How to Choose an API Security Tech Stack

How to Choose an API Security Tech Stack APIs are rapidly on their way to becoming the most popular attack vector. That's why ensuring you have a good security strategy in place is essential— the right tech stack can help with this. There are many tools on the market to choose from, each with features that help secure your digital assets. But how do you sort through these API security tools to build the right stack for your business? In this blog post, we'll walk you through the different types of security testing tools and which factors you need to look at when choosing the best stack for your needs. TLDR Key Takeaways Your security stack is usually made up of a few different types of testing tools, each designed to complete specific tasks. With automation, you can test every combination of inputs and outputs and reduce various human errors, especially when time constraints or budget make manual testing unaffordable. If your security solution isn't designed with speed in mind, you might be prolonging the development process and ultimately jeopardizing the system's integrity. 4 Types of API Security Testing Tools Just as a writer may use a range of copywriting tools to help them fine-tune their content, your security stack is usually composed of a few different types of security testing tools—each designed to complete various tasks. Let's break down the four most common types of testing tools you'll run into: Penetration testing tools: They simulate real-world attacks on APIs and are used to identify vulnerabilities hackers may exploit. Some popular penetration testing tools include Kali Linux, Burp Suite, and OWASP ZAP. Vulnerability scanners: As the name implies, these tools scan for known API vulnerabilities and are used to find both security and performance issues. Some popular vulnerability scanners include Acunetix, Nessus, and beSECURE. Bug bounty programs: These allow companies to crowdsource security testing by offering rewards for finding vulnerabilities. Some popular platforms to host bug bounty programs include HackerOne and Bugcrowd; alternatively, your company can host its own program. Continuous API security testing solutions: These tools provide automated tests that run on a regular basis, helping you find issues quickly and ensure that they are fixed in a timely manner. Some popular continuous API testing solutions include APIsec, SoapUI, and Postman. When looking at different technologies for your tech stack, it's important to take the time and evaluate what each one offers, as each has its own advantages and disadvantages. For example, some tools are very limited in their capabilities, only focusing on securing certain aspects of your API. This will require you to invest in additional tools to cover what's left over. On the other hand, some tools, like APIsec, allow you to combine multiple types of testing in a single solution, giving you comprehensive coverage. Drilling Down Into the Factors You Need to Consider When Choosing Your API Security Tech Stack Now that you understand the types of testing tools you'll run into, it's time to look at how you'll evaluate whether or not the tool is right for your tech stack. We've gone ahead and drilled down into the most critical factors you'll need to examine to make an informed decision. The following is a quick cheat sheet that covers the main things you should consider and how they stack up for each testing type: Automation Automation is arguably the most crucial factor to consider when choosing your API security tech stack. Why? Because if you're not automating your API security, you're doing it manually. And that's a huge mistake. It's nearly impossible to manually test every possible input and output combination because there's simply not enough time in the day or a big enough budget. On top of that, manual API security is error-prone and not feasible at scale. That's why automation is absolutely essential for your testing tools. Automated testing allows you to: Cover a much larger attack surface Run tests more frequently Identify and respond to threats much faster than manual testing Reduce operational costs Reduce human error Ideally, you should look for a solution that offers a high degree of automation so that you can set it up once and then forget about it. That way, your teams can focus on more important things, safe in the knowledge that your APIs are well-protected. Coverage As the threat landscape continues to evolve, malicious actors are always looking for new ways to exploit vulnerabilities in your APIs, which is why you need to ensure you have complete coverage. If you don't take coverage into account, you may find yourself with gaps in your protection. Attackers can exploit these gaps, leading to data breaches and other security issues. Most security testing tools only focus on identifying commonly known vulnerabilities, such as OWASP's Top 10, but they fail to catch business logic flaws. To ensure adequate coverage, you need to select an API security solution that offers comprehensive protection that will be able to protect against a wide range of threats, including legitimate users who are abusing their privileges. Costs If it were up to your dev and security teams, you'd probably utilize dozens of testing tools, but unfortunately, your budget probably can't handle that many tools. When deciding which tools you want to include in your security tech stack, you'll need to weigh the upfront costs of the solution against the long-term benefits it provides. If you don't carefully consider the cost of your API security solution, it could end up costing you more in the long run, as you'll need to supplement with other testing tools. For example, manual pen testing is extremely expensive, and most businesses can only afford to complete tests annually, meaning you have to adopt another solution to ensure your API is secure for the other 364 days of the year. On the other hand, you might invest in a more budget-friendly bug bounty program, but you end up missing critical vulnerabilities because you didn't have the budget to offer attractive payouts. It's crucial to take the time to consider all of the costs associated with API security and to choose an affordable yet effective solution. Doing so can ensure that your business is protected from the ever-growing threats posed by cybercriminals. Scalability As your business grows, you'll need to be able to scale up your API security solution accordingly. Otherwise, you may find yourself with inadequate security setups that leave your system vulnerable and cause major bottlenecks. For example, you might add new APIs, roll out new versions of your product, or create new packages. All of these actions create new endpoints, calls, and parameters that require testing to be secured. By taking scalability into account from the beginning, you can avoid these issues and ensure that your API can grow with your business. Accuracy You could have a top-of-the-line security solution with all the bells and whistles, but if it's inaccurate, what good is it? All you'll end up with is a noisy system that produces an overwhelming amount of false positives your team will have to filter through. Eventually, something will slip through the cracks, and it will compromise your system. Instead, you need tools with a high accuracy rate so you can: Ensure the data being passed through the API is correct and consistent Improve the overall performance of the system by reducing latency and improving response times Identify attack warning signs quickly Investigate and respond to incidents in a timely manner Ideally, you should look for a solution that has a high degree of accuracy so that you can be confident that any alerts are genuine threats. Speed The importance of testing speed is growing as DevOps teams adopt agile practices. This means that security testing needs to be done quickly and efficiently. Unfortunately, many API security solutions are not designed with speed in mind. This can lead to delays in the development process and ultimately jeopardize the system's security. The faster you can test, the faster devs can identify and fix vulnerabilities. Plus, it's easier to fix bugs early in development while code is still fresh in their minds than it is to fix them in production. To ensure that your API security tech stack includes fast and effective testing, you'll want to look for: Support for parallel testing: Parallel testing allows you to run multiple tests simultaneously, which can greatly speed up the testing process. A comprehensive test suite: A comprehensive test suite will cover all aspects of your API, including functionality, performance, and security. Flexible reporting options: Flexible reporting options allow you to customize the information you receive from your tests. This can help you identify areas that need improvement and track progress over time. Reliability Just like we discussed with accuracy, what's the point of having security measures in place if they're not going to be reliable? Malicious actors are constantly looking for ways to exploit these "doorways" into your application and its sensitive data, and if your API security solution is unreliable, it can leave your API vulnerable to attack. An unreliable API security solution may not be able to detect and defend against emerging attacks, leading to data breaches, loss of customer trust, and damage to your brand. Don't gamble with your API security. Choose a solution that is backed by a team of experts who are constantly monitoring the latest threats and developing new defenses.

What the OCC's Bank Supervision Operating Plan for Fiscal Year 2023 Means for Community Banks and FinTechs

Open Banking places consumers at the center of a banking experience made up of interconnected, yet independent services. At the same time, Open Banking offers technology-forward banks the chance to reshape their business models and re-orient their relationship with clients to grow market share and increase profitability. At the heart of the Open Banking revolution is data; specifically the infrastructure of databases, data standards, and open APIs that make the free flow of data between banks, third party service providers, and consumers possible. Priority Objectives for CBS Operating Units The emphasis for fiscal year 2023 is on risk-focused bank supervision, specifically cyber security and data protection. “The threats for many financial institutions continue to expand at a rapid pace as the interconnectedness of multiple specialized service providers and FinTechs increases, digitalization of critical infrastructure components proliferates, and reliance on cloud services grows rapidly.” Per the OCC Bank Supervision Operating Plan for Fiscal Year 2023, in the coming year, the OCC will focus more on a select few key areas. Third-parties and Related Concentrations Third-party relationships are a source of financial institution risk, but it is important to understand how these risks appear and what steps taken by banks can reduce them. Common risk attributes include: Customer-facing products and services Critical elements needed for bank operations Significant concentrations Factors that may affect the bank's operational resilience Regulatory compliance, including Bank Secrecy Act and consumer protection laws Examiners must determine whether the bank and third parties possess adequate, qualified personnel to mitigate these risks and meet contractual obligations. Additionally, examiners must evaluate how the bank assesses a third party's cybersecurity risk management and resilience capabilities. New Products and Services To remain vigilant, bank examiners should assess whether banks can still see potential threats in new growth opportunities. As part of the strategic planning process, they must understand how innovative or new activities offered through third parties affect financial performance and risks. Payments: Examiners should evaluate products and services (both new and existing) for potential operational, compliance, strategic, credit, liquidity, and reputation risks. Additionally, they should consider how they will assess and manage these risks in their institution-wide risk assessments, as well as new product reviews. FinTech and digital assets: Examiners should identify and evaluate changes to governance processes for banks applying new technological innovations to their operations, such as: Cloud computing Artificial intelligence Digitalization of risk management processes Engaging in banking-as-a-service arrangements Crypto-related products and services and other new products and services need to be evaluated by examiners for risk management practices, which include: Evaluating due diligence activities Assessing the expertise needed to manage technology, financial, operational, compliance, strategic, reputational, and other risks. Operational Resilience and Cybersecurity To ensure FinTechs are resilient to the ever-changing cybersecurity threat landscape, examinations must focus on fundamental controls to identify, detect, and prevent threats and vulnerabilities. These include, but are not limited to: Authentication Access controls segmentation Patch management End-of-life programs Additionally, auditors should assess how effective the governance processes are in relation to technology investment and implementing changes in systems and infrastructure. What Does This Mean for API Security Teams? With the Office of the Comptroller of the Currency's Committee on Bank Supervision prioritizing cybersecurity more than ever before, banks and FinTech companies should shift their focus accordingly to ensure a safe environment for their users. This means taking proactive measures to protect their digital infrastructure from data breaches and other cyber threats. But with so many attack vectors, how should you prioritize your efforts? Gartner knows the answer, projecting that APIs are well on their way to becoming the primary attack vector in 2022 and beyond. Your APIs are the main target for cybercriminals trying to access your financial data, so your cybersecurity strategy for 2023 should prioritize API security. Top 4 Tips to Protect Your FinTech APIs Now that you know that APIs should be your main focus, how should you prioritize your efforts? To help you get started, here are some actionable tips to reduce your API attack surface and minimize your risk. 1. Cover the OWASP API Security Top 10 List You need to cover the essentials first, so it's a good idea to start by tackling some of the most common API vulnerabilities and threats. Fortunately, you don't need to hire an expensive cybersecurity firm to get the list of action items. It already exists, and it's called the OWASP API Security Top 10 list. This list is developed by OWASP, an industry-leading non-profit organization that aims to promote a safer Web by spreading awareness around the most common cybersecurity threats. The API security top 10 list is explicitly tailored to APIs, giving you an idea of which vulnerabilities you should prioritize. ‍ Here's a quick recap of the OWASP Top 10 list: ‍ 2. Analyze Your APIs for Business Logic Flaws While the OWASP list covers the most popular attack vectors, business logic flaws are, by far, the most dangerous ones. Why is that the case? Business logic vulnerabilities occur when the attacker can abuse the flaws in the legitimate functionalities of your APIs, allowing them to gain unauthorized access to data without resorting to any exploits. But what makes them truly dangerous is the fact that since this cluster of vulnerabilities occurs because of how the API is built, they're virtually impossible to detect at scale with penetration testing, vulnerability scanning, or bug bounty programs. Every API has its unique architecture, meaning that each API will have its own unique business logic flaws. This is why tackling this API threat is so paramount. 3. Implement a Zero-trust Security Model Most systems rigorously monitor requests from new users. But once they're in, they give them a certain level of trust, meaning that the system no longer views them as a threat. This approach fails as the attacker can easily take advantage of your APIs once they’ve gained access. That's where the zero-trust security model comes in. As opposed to trusting a certain group of users based on their privilege level, the model treats everyone as a potential security threat at all times. This means that every user and every request should be constantly monitored and evaluated from a security perspective, drastically reducing the likelihood of a successful data breach. That's why implementing the zero-trust security model across all of your API assets can help you add another layer of security. 4. Implement Automated API Security Testing Whenever your API is updated, you potentially open up new loopholes that attackers can abuse. Traditional testing methods are time and labor intensive, as well as costly. As a result, most organizations test their API security only once or twice a year, leaving their APIs ripe for the picking. However, with the rise of AI and machine learning came solutions that allow for automated, comprehensive, and continuous API security testing at scale. One of them is APIsec. APIsec is a fully automated API security testing solution that can automatically dissect every corner of your APIs to generate thousands of custom-tailored attack scenarios and execute them in minutes. Solutions like APIsec helps you security test for the entire OWASP list as well as business logic flaws that are unique to your APIs. Now your application security teams can run a full security check on every build for a fraction of the cost of manual pen testing. ‍ ‍ ‍

FAQ Why Should You Perform Penetration Testing? Performing penetration testing is important for a number of reasons. For starters, it helps identify vulnerabilities in your system that attackers could exploit. By testing your system's defenses, you can ensure that they are up to par and able to resist attacks. Penetration testing also improves your organization's security posture. When you identify and address weaknesses in your system, you can reduce the risk of data breaches and other security incidents by making it more difficult for attackers to breach your network. Additionally, penetration testing provides valuable insights into your organization's security processes and procedures. Conducting tests regularly helps you identify areas where improvements can be made. All this knowledge is used to refine and improve your organization's security posture. How is Penetration Testing Automated? In the past, penetration testing was a manual process that required significant time and resources. However, with the advent of new technologies, penetration testing can now be automated. To conduct an automated penetration test, security professionals need to identify the targets for testing, such as websites, web applications, network infrastructure, etc. Once the targets have been identified, they will need to configure the automated tools and processes for testing. Then, the automated penetration testing process will begin. The tools and processes will work to identify vulnerabilities in the target systems and applications. Security professionals will need to analyze vulnerabilities and determine which pose a risk to the organization once they have been uncovered. There are a number of different tools that can be used for automated penetration testing (some of them are listed above). How Much Does Manual Pen Testing Cost? The cost of manual pen testing depends on a number of factors, including the size and complexity of the system being tested, the level of expertise of the testers, and the time frame in which the testing needs to be completed. Generally speaking, manual pen testing is a major expense for an organization, costing anywhere from a few hundred dollars to several thousand dollars.

How to Continuously Test APIs (and Why That's Impossible for Bug Bounty Programs)

What Determines “Continuous” API Testing? Continuous API testing runs ongoing, automated, evolving tests against an API to ensure high performance and security. This testing is typically carried out throughout the development lifecycle to catch any bugs or vulnerabilities before the API is released. There are a few key factors that determine whether an API testing solution is truly continuous: Automation: A continuous API testing solution should be automated to run tests independently, without manual intervention. This way, the testing process can keep up with the pace of development and ensure proper security testing against all changes before they're released. Comprehensive coverage: A continuous API testing solution should provide comprehensive coverage of an API, including all endpoints and parameters, to ensure that no bugs or vulnerabilities slip through the cracks. Adaptability: A continuous API testing solution should constantly evolve its tests to keep up with changes in the API landscape. As new threats arise, tests should be updated to address them. Scalability: A continuous API testing solution should be able to scale up or down as needed, depending on the size and complexity of the API being tested. Here is a summary of how each method stacks up: Why is Continuous Security Testing so Hard? Many CISOs and members of the AppSec community find it hard to believe that any platform can effectively automate API security testing to cover the entire OWASP list. Those concerns are valid because finding the most dangerous vulnerabilities, like business logic flaws, is notoriously difficult because they're usually found deep within an application's code. To complicate the matter even further, business logic flaws aren't errors in the coding. Rather, these flaws exist in the application's logic, so any scanner looking for flaws in the code would fail to identify the dangerous vulnerabilities. Application complexity, the vast number of endpoints, and ever-expanding potential attack vectors have historically made it impossible for any engineering team to programmatically test for all possible security flaws. That's no longer the case. With the help of recent advancements in machine learning, automated API testing platforms, like APIsec, provide continuous, comprehensive testing coverage of an API, including all endpoints and parameters. Dev and security teams were historically stuck with limited options for protecting their APIs, the most popular being manual pen testing, vulnerability scanning, and bug bounty programs. Let's quickly break down each testing method, how they work, and where they come up short. Manual penetration testing is a process in which testers manually attempt to exploit vulnerabilities in an application. Some concerning issues with manual pen testing include: It's time-consuming and expensive since it requires highly skilled testers manually writing hundreds or thousands of tests that can take weeks or even months to complete. It's a point-in-time test that doesn't cover continuous code updates leaving significant windows of high vulnerability in the time between pen tests. Vulnerability scanning is similar to manual penetration testing but uses automated tools to scan for known vulnerabilities. Vulnerability scanning can be a fast and cost-effective way to find some security issues, but it has several limitations, including: It can only find known vulnerabilities, so as new flaws arise, they will go undetected. It can be noisy, creating many false positives that waste security and development resources chasing down phantom vulnerabilities. It can't find business logic flaws, which are often the most dangerous. Bug bounty programs consist of a crowd of ethical hackers who are paid to find and report vulnerabilities in an application. While this can be a helpful way to supplement other testing methods, it has several drawbacks: It’s time-consuming to set-up properly and requires continuous management to ensure researchers stay focused. It's reactive approach only tests for vulnerabilities after they’re in a production environment, leaving potential vulnerabilities exposed for weeks, months, or even years. It's often used as a replacement for other testing methods, which can be dangerous since it provides incomplete coverage. Bug bounty programs, along with manual pen testing and vulnerability scanning, can often do more harm than good by creating a false sense of security. Continuous testing is the only way to effectively protect your APIs from vulnerabilities, automating the entire process, including incorporating detailed reports directly into your CI/CD pipeline. While pen testing, vulnerability scanning, and bug bounties can be valuable tools in your API security arsenal, they simply can't provide the same level of coverage or speed as continuous, automated testing. Continuous Testing Starts with the Right Tools The first step to protecting your APIs using continuous testing is finding the right tool. Up until this point, we have only covered continuous testing for API security, but that’s only one piece of the puzzle. To truly test your API continuously, you need to find a suite of tools that cover every part of the API journey from security to functionality. No matter what type of testing you want to run, you should evaluate solutions based on their ability to execute the options we covered earlier: automation, comprehensive coverage, adaptability, and scalability. Next you should look at each solution’s ease-of-use, support, price, and any other feature that matters to you... here is a snapshot summary of tools that we love: We actually broke these tools down in more detail when we wrote this post covering the Top 5 API Security Tools on the market today, when to use them, and why we recommend them. Key Building Blocks of Continuous API Security Testing Are you ready to start continuous API security testing? Here are three key steps to take as you work toward a continuous API security testing environment: 1. Identify any manual bottlenecks in your security process today, and automate them. Automating as much as you possibly can is the cornerstone of continuous testing - not only will this strengthen your security, but it will free up your team to focus on other key tasks since testing will no longer require valuable human resources to perform (automation offers a significant, lasting ROI).‍ 2. Integrate everything directly into Continuous Integration / Continuous Delivery It’s highly likely your organization is already leveraging CI/CD technology to improve product quality and developer productivity. Don’t “re-invent the wheel,” rather, leverage these same processes/technology to test new code when it’s ready without needing to manually trigger a test. 3. Leverage your current developer feedback loop Finding a security vulnerability is only the first half of API security testing. Someone needs to fix them. This often requires inter-team communication for security engineers to recruit developers to fix these critical issues. As we mentioned before, there are existing processes you can leverage to deliver feedback to developers without the added manual step. Integrating with Developer Ticketing or Productivity software is a guaranteed way to prevent slowing the pace of development without missed issues, which may lead to deploying exploitable vulnerabilities to production. Ensure Continuous API Security Testing with APIsec Continuous API security testing is well on its way to becoming the new norm thanks to its scalability, accuracy, and cost-effectiveness. If you still haven't adopted continuous API security testing, you're almost guaranteed to leave your APIs exposed to data breaches and other cyber threats. For years, organizations had to rely on pen testing, vulnerability scanning, and bug bounty programs to protect their API assets. APIsec offers a superior alternative to all of them. By leveraging the power of AI and machine learning, APIsec can automatically generate and execute hundreds of custom-tailored attack scenarios based on the unique architecture of your API.

The Hidden Risks of API Monitoring That Leave APIs More Vulnerable

‍API Monitoring: A Quick Refresher API monitoring is the process of checking your API's endpoints and data exchanges to make sure they're functional, available, and performing as expected. This allows developers to identify and fix API issues before they impact the end-user. Additionally, you get visibility into how well each function within the API operates by viewing metrics such as the number of API function calls, the time it takes to respond to those calls, and the amount of data returned. In today's world, monitoring is essential to ensure your APIs are sustainable, the applications that depend on them receive the services/data they need while the end-user has a streamlined experience. Some companies think that API monitoring is enough to cover all of their API security needs. Here are 5 reasons why API monitoring alone is not sufficient to ensure API security. 5 Risks of API Monitoring That No One Wants to Tell You About While API monitoring gives you insight into certain information, there are some areas that slip through the cracks. We've put together a list of the most important vulnerabilities your API monitoring tools are missing. 1. Monitoring Tools Cannot Identify Business Logic Vulnerabilities Business logic can't be parsed using API monitoring tools, which means you won't discover an entire cluster of potential security risks that exist in your API governance Business logic vulnerabilities are either weaknesses or bugs in the design or legitimate functionalities of an application. Because business logic is unique to every application, business logic vulnerabilities typically go overlooked until your data has already been compromised. In late 2021 a security researcher ran vulnerability research on a group of financial services and FinTech companies. Every single API tested contained business logic flaws which created Broken Authentication vulnerabilities that allowed the researcher to perform API requests on other bank customer accounts without authenticating. That's what makes these vulnerabilities so dangerous. The fact that these vulnerabilities are often exploited without the need for special tools or techniques makes them widely cited as the number one API security threat. Since these vulnerabilities are rooted in your API's governance, you'll need to have a deep understanding of every process, rule, and workflow that directly or indirectly informed the setup of your API. 2. False Positives and Negatives Cause Teams to Miss Auditable Events API monitoring tools have a tendency to produce a fair amount of false positives while simultaneously missing other potential auditable events. An auditable event occurs when a user performs a certain action that may affect the security of your API or correlates to a security breach, such as: Changing or deleting policies, permissions, and data Making large transactions Failed login attempts Altering system functions Since many API monitoring tools run on pass/fail alerts that are based on your API’s governance, many IT departments find themselves overwhelmed with the number of false positives they need to investigate, especially if the ticket doesn't include enough information. It's like having a doorbell camera that alerts you every time a car goes by; eventually, you stop looking at the notifications and miss an important event. Similarly, IT teams either deprioritize their investigations or become less confident in their monitoring tool—IT teams reported that 44% of their alerts go unexplored, exposing them to potential attacks. When teams fail to investigate false positives promptly, they run the risk of missing an actual threat to the system. This is one of the main reasons why insufficient API logging and monitoring are listed as one of OWASP's Top Ten API Security threats. 3. Synthetic API Monitoring Tools Fail to Simulate Real-world Events Synthetic monitoring, sometimes called synthetic testing, was developed as a proactive way to test your API, but it does little more than conduct basic acceptance tests to check your API's performance. Synthetic monitoring involves a monitoring client actively sending a previously-made client request to your API, meaning that they aren't monitoring what your users are currently doing. While using these predefined requests helps you assess your API's performance, it only accounts for what you anticipate or what some users have done in the past. Additionally, these tests only occur on single endpoints, severely limiting their ability to detect functional errors. Synthetic monitoring tools don't unify work silos, they create more. This means the teams with the deepest knowledge of creating real-world tests specific to your API won't be involved in their creation. 4. API Monitoring Cannot Continuously, and Proactively Test API Vulnerabilities While you can set up a monitoring routine that runs at regularly scheduled intervals throughout the SDLC lifecycle, you'll find that API monitoring is nowhere near enough to ensure continuous API security testing. Continuous testing is the process of integrating automated testing into SDLC pipelines so that businesses can identify and resolve risks quickly and efficiently. This is done by applying shift-left testing methodologies, which only work if your testing doesn’t slow down your dev team. While API monitoring tools complement continuous testing methods by adding another layer of screening on their own, they aren't enough to ensure security and can’t keep up with new cybersecurity threats. 5. Monitoring Can't Match Specialized API Security Testing Solutions API monitoring tools claim to analyze your entire API, but they only return certain metrics without providing your details to the underlying cause of a vulnerability—or miss it altogether. On the other hand, specialized API testing solutions, like APIsec, are designed to dissect every endpoint, variable, method, and input parameter to uncover hidden API security threats, including business logic flaws. APIsec has the perfect plan to keep your API safe and secure. Check out this quick demo to see how the platform works: Our engine creates thousands of automated attack playbooks, which are designed for testing every corner of your system so that you can be confident no vulnerability is left uncovered.

Shift Left Security: The Ultimate Guide

GitHub estimates that developers outnumber security professionals 500 to 1, meaning organizations need to integrate shift left security measures into their development to stay competitive. The use of traditional testing is often not in line with DevOps, which emphasizes delivering features and updates from one production stage to the next without unnecessary delays. How did they fix this? By implementing agile methodologies, like shift left, into DevOps practices. Shifting left means integrating testing and security activities into every relevant stage of development, from design to production. How Shift Left Impacts Security Shifting security left means taking a new approach to how DevSecOps teams develop and design software. The goals of this shift are simple: Build security best practices into your process from start-to-finish Detect potential issues as early in the lifecycle as possible Fix problems quickly without expensive miscalibrations later down the line Maintain an affordable price point for any company or organization To do this effectively and efficiently, developers must be aware of what they need during each stage to avoid gaps in their defenses against vulnerabilities that malicious actors could use. Integrating CI/CD into SDLC The adoption of CI/CD transforms the SDLC as it automates and monitors every step of the development process, from code integration to live production environments. In addition to reorganizing teams into DevSecOps teams, companies will have to incorporate security testing earlier into their deployment pipelines as CI remains crucial for software development. Benefits of Shift Left Security Shift left testing is a powerful way to identify and fix defects before they become costly, meaning your team can make faster progress in the development cycle. Other benefits include: Improve code quality and security posture Easily manage risks with cloud technologies Create a security-conscious culture Continual assessment Driving Technologies for Shift Left Security To make sure organizations maintain a high level of security, OWASP suggests DevSecOps use a variety of tools. Here are five commonly used tools: SAST (static analysis) DAST (dynamic analysis) Interactive Application Security Testing (IAST) Software Composition Analysis (SCA) Cloud Security Posture Management (CSPM) How to Implement Shift Left Security: 5 First Steps Shift left security can be implemented in a number of ways, but these are the most crucial steps. 1. Establish and Define Shift Left Security Strategy It's critical that you identify what shift left means for your team to help them understand how to achieve success. To do this, you'll need to: Define Common Goals The goal of DevSecOps is to promote collaboration and alignment among all stakeholders involved in the development process. To do this, teams need to come together to clearly establish their goals and objectives for their shift left security strategy. This should include: Who has ownership or responsibilities over what processes? What metrics will be used to gauge success? What parts of your applications and APIs operate with sensitive data? How many resources are you willing to allocate to the testing process? What will your milestones look like? Change the Culture Enable a security-centric development environment where security is considered at every stage of the development lifecycle—whether it's selecting a package during project planning, developing code, or conducting tests. You'll most likely have to do some shift left myth-busting to facilitate a smooth transition. The most common misconception is that shift left means moving the testing to an earlier stage and then neglecting to test later. Establish a Set of Security Requirements for APIs Because APIs are windows into your system, the safety of an application depends on the security policies you establish for them. Including security requirements for APIs in your shift left security strategy, will boost your security posture. There are a few factors to consider when establishing a set of security requirements for APIs, such as: The type of data being accessed by the API The environment in which the API will be used The user base that will be using the API For example, if the API is accessing sensitive data in a public environment by many users, then a higher level of security will be required. When determining the security requirements for an API, it is essential to consult with experts in the field. They will be able to help identify what security measures need to be put in place to protect the data that is being accessed by the API. They will also help determine what level of security is needed. 2. Understand Where Software is Created Understanding your software development pipeline is an important first step in securing it. This will be more challenging depending on the complexity of your business units. Before you can start shifting security left, identify who's responsible for developing code and how that person or team moves from creating new features through deployment to production. This helps you identify what technology will be used throughout this process, so there are no gaps. Make sure you identify: The individuals responsible for developing code The workflow process The technology used in this process 3. Implement Security Controls at the API Level Through APIs, applications and software interact with your business, allowing outsiders direct access to sensitive information. Without proper security measures in place, cybercriminals will exploit these vulnerabilities. To address OWASP's Top 10 API security risks, it's recommended that you implement security controls at the API level, which help protect your data and systems. Some of the most widely used security measures are: Authentication and Authorization: Ensure only authorized users access the API using OAuth 2.0 or OpenID protocols. Encryption: Protect the data that passes through your API from interception and tampering, for example, using SSL/TSL encryption. Principle of least privilege: With this principle, subjects are granted only the minimum access necessary to complete a stated function—this includes access to your APIs. Use rate limits: To prevent denial-of-service attacks, set a threshold above which subsequent requests will be rejected. 4. Automate Security Processes Penetration testing and vulnerability scanners are the most common ways to test the security of your APIs. However, they each have unique problems when using a shift left security approach. Vulnerability scanners are deployed to test your APIs against a list of known vulnerabilities, but they do not consider your API's architecture. This means they miss business logic flaws that leave you vulnerable. On the other hand, pen testers use black box or white box testing methods to simulate attacks on your API, which are extremely time-consuming and expensive when applied to the shift left testing framework. But there’s a third way. You can use APIsec. APIsec is an automated security testing solution that uses AI to analyze the architecture of your APIs to generate and execute hundreds of custom-tailored attack scenarios. 5. Implement Security Fixes as the Code is Developed It is important to implement security fixes as you develop the code so that your application and APIs have no vulnerabilities. It’s a good idea to retest once you fix your code as loopholes often open up after remediation. This ensures no weak spots are left where an attacker could exploit simple errors.

What is Broken Object Level Authorization (BOLA) and How to Fix It

With APIs projected to become the main attack vector in 2022, companies that downplay the importance of API security risk making the headlines as the next victim of a major data breach—losing customer trust for years to come. While most API threats are relatively easy to catch using vulnerability scanners, some can remain undetected for years. This makes them a ticking time bomb until bad agents spot them. Today, we're going to cover one of them. Broken Object Level Authorization (BOLA) vulnerabilities sit at the top of the OWASP API Security Top 10 list. Why is that the case? Keep reading to find out the answer and learn how to protect yourself from it. What is Broken Object Level Authorization, and Why Is It #1 on the OWASP Top 10 List? Object-level authorization is a security measure that controls which users can access which objects, be it database records or files. For example, a user might be allowed to view specific files but not edit or delete them. Broken object-level authorization (BOLA) vulnerabilities occur when a user is able to access other users' data due to the flaws in authorization controls validating access to data objects. BOLA vulnerabilities are often caused by insecure coding practices, such as failing to properly validate user input or check permissions before granting access to an object. This happens when an API uses overly permissive access controls or when API resources are not properly protected. BOLA vulnerabilities lead to devastating data breaches and other ramifications. The USPS hack, one of the largest data breaches in history, happened because of, you guessed it, broken access controls. “The USPS hack is a classic example of a broken authorization vulnerability. User A was able to authenticate to the API and then pivot and access user B’s and 60 million other people’s information.”- Dan Barahona, Head of Marketing at Biz Dev at APIsec How to Protect Your APIs from BOLA Vulnerabilities Since BOLA vulnerabilities are the most dangerous cluster of API threats, companies need to take proactive steps to prevent them. Here are the most effective ones. 1. Enforce Robust Authorization Mechanisms Enforcing robust authorization mechanisms is the first step any organization should take to combat BOLA vulnerabilities. Many organizations think their APIs are secure because they have strong authentication. But that's not really going to help a whole lot when it comes to BOLA vulnerabilities. To keep your APIs safe, you need strong authentication mechanisms, but the bigger challenge is ensuring you've got well-controlled authorization policies that you are testing rigorously and continuously to make sure they're free of logic flaws or loopholes.2. Use Random Universally Unique Identifiers (UUIDs)The next step is redefining how you approach the process of generating and managing IDs within your API ecosystem. Auto-incrementing IDs absolutely have to go. As an alternative, use random IDs when creating and accessing APIs. These IDs, commonly referred to as UUIDs, are designed specifically to be difficult for cybercriminals or unauthorized users to guess. UUIDs are made up of a combination of letters, numbers, and symbols that have no inherent meaning or pattern, making them virtually impossible to guess or reverse-engineer. Using UUIDs minimizes the risk of malicious tampering, one of the root causes of BOLA vulnerabilities.3. Laser-focus on Your Business Logic Layer BOLA vulnerabilities are so tricky because they often lurk in the business logic layer of your APIs. The implications? It means that BOLA vulnerabilities typically occur due to the flaws in the design of the legitimate functionalities of your APIs rather than bad agents using complex exploits to break into your systems. That's why it's critical to meticulously test your business logic layer to spot vulnerabilities that are impossible to reliably address upon each release with vulnerability scanners. “BOLA is already #1 on the OWASP API Security Top 10 list - and for good reasons. API providers do a great job at making sure that users are authenticated to the API, so they want to make sure that legitimate users have access. But the number one thing that's often overlooked is authorization, ensuring that user A can't access user’s B resources. And it's one thing to hide the resource IDs, but the important factor there is that user A should not be able to access, interact with, or alter user B's resources - at all.”- Corey Ball, Cybersecurity Consulting Manager and Author of "Hacking APIs"4. Implement the Zero-Trust Security Model Enforcing the zero-trust security model is another step organizations typically take to protect APIs from BOLA vulnerabilities. In a traditional security model, authorized and authenticated users are trusted by default. However, in the zero-trust security model, all users must be authenticated and authorized before accessing any resources. Additionally, the authorized users are constantly monitored to prevent insider threats. Based on this model, each API call must be authenticated and authorized before it can be executed. Once the user has been authenticated, the authorization mechanisms in place determine whether the user is allowed to access the requested resource. If the user is not authorized, then the API call will not be executed, making it more difficult for attackers to exploit BOLA vulnerabilities.5. Ensure Continuous API Security Testing This is arguably the most effective way to protect APIs from BOLA vulnerabilities. However, here's the rub. Traditional API security testing tools aren't reliable since vulnerability scanners don't take into account the unique architecture of your API while pen testing is impossible to scale to ensure full coverage with each update. This is where APIsec comes into play. APIsec is an industry-leading solution that leverages the power of AI to dissect your API and generate custom-tailored attack scenarios aimed at identifying business logic vulnerabilities. APIsec is the only reliable way to automatically secure your API from BOLA vulnerabilities and, most importantly, business logic flaws while ensuring full coverage and eliminating human error.

Penetration Testing Best Practices for Every Stage of Testing

Due to the ever-changing cyber threat landscape, it's more important than ever for businesses and governments around the world to recognize and protect themselves from potential cybersecurity risks. Even if you think that your company's security measures are on point, there's always a chance they won't be enough to prevent an intrusion. Penetration tests uncover cybersecurity weaknesses in your systems and reveal how attackers could potentially exploit them before it becomes too late. These tests are an essential security practice where you intentionally attack your applications, networks, APIs, and computer systems to find and exploit vulnerabilities. By following our best practices for effective results, you ensure that your organization gets the most out of its penetration testing initiative. Pen Testing Best Practices No matter what stage of the testing process you're in, we have aligned our best practices with your needs to provide the most helpful information. Scope1. Set Clear Objectives The first step in developing a secure test is to plan it by setting your scope. This involves selecting specific objectives and conditions for your test that will affect the outcome. For example, you might want to cover an entire network, certain applications within that network, test the security of your APIs, or even specific users who work remotely from home offices. The objectives and goals of a penetration test often vary greatly, from improving security to ensuring compliance with regulations. You'll need to clearly understand, "Why are we even doing a pen test?" To avoid wasting time and resources on unimportant areas, focus on the high-risk vulnerabilities that are likely to be exploited first. During this process, your team should clearly: Evaluate the reasons for conducting pen testing Define the target environment Identify resourcing requirements Establish and define liabilities Determine the testing to be conducted Discuss follow-up activities 2. Establish your Budget Your budget is one of the most important things to take into consideration when you're looking for a security solution. The price you pay for security depends on the value of your assets and what kind of objectives you are trying to achieve. Factors that affect your budget: In-house testing versus hiring an external service provider Type of testing you want to do (black, white, grey, or red teaming)The amount of time needed to conduct the test The scope and coverage focus One way to keep your costs down is to use automated testing instead of manual testing. Another way to eliminate costs is by using white box testing, which gives the tester all the information they need to find vulnerabilities faster. Remember, there is no one-fits-all solution because every organization has its own needs that translate into dollar figures—the more coverage you want, the more you pay. Expertise3. Choose a Penetration Testing Methodologies There are five common methods you can use for a penetration test, and the results will vary depending on which one is employed. Open Source Security Testing Methodology Manual (OSSTMM): This peer-reviewed methodology provides technical details for identifying what needs to be tested, how to measure the results, and what to do during every step of testing. Open Web Application Security Project (OWASP): This industry-leading organization is dedicated to improving cybersecurity by providing lists of the most common cyber threats as well as tools, forums, and documentation to anyone who needs them. National Institute of Standards and Technology (NIST): The methodology by which NIST approaches security assessment of information technology systems is less comprehensive than the OSSTMM; however, their approach is more accepted by regulatory agency standards. Information System Security Assessment Framework (ISSAF): This peer-reviewed framework provides field inputs for security assessments for real-life scenarios. Penetration Testing Execution Standard (PTES): This methodology was created by industry specialists and provides a common language standard for penetration testing. Pro Tip: External pen testers use varying methods. Make sure their methodology aligns with what's necessary for this test, and make it clear from day one which objectives need completion before they start testing.4. Find the Right Pen Testers When hiring pen testers, make sure you ask the right questions and find the right experts for your target domains: if it's API security, look no further than those who specialize in this field. An expert will know how systems are built as well as their common weaknesses, so they'll help guarantee the success of any pen test by taking advantage from all possible angles. Advantages of hiring external penetration testing providers: They have experienced staff dedicated to conducting highly-effective tests. They complete independent assessments that provide a comprehensive analysis of your security posture. They conduct a wide variety of testing that satisfies any environment and objective.5. Prepare for the Pen Test In order to ensure your pen test yields maximum results, you'll need to: Request sample reports from your pen tester. If anything, in particular, catches your eye or interests you (for example, missing data points on important metrics or the findings don't include enough non-technical corrective actions), indicate this when making queries during regular meetings. Clean up the test environment by restoring it back as close to its original state. Ideally, you want to test in a live environment, but many perform their tests in development test environments to avoid disruptions. Make sure your team is ready for anything by identifying those who will review the test report and fix any issues that were discovered during testing. Grant proper authorizations to conduct testing if needed.Monitor6. Establish Monitoring Solutions Make sure that your security monitoring solutions are in place before starting a pen test. Not only will this help you oversee the testing performance, but you'll also be able to make sure appropriate actions are taken when necessary. To do this, we recommend: Implement logging: This is a vital component in security monitoring and investigation because it provides insights into pen tests' impacts on your systems as well as identifying potential vulnerabilities before they become threats. Establish risk management processes: They should cover many areas, including tests that don't work as planned or problems caused by penetration testing gone wrong. Additionally, they should look for breaches in contract/codes for both company and individual policies regarding security vulnerabilities and provide ways for effective resolutions when needed.Remediation7. Prioritize Pen Test Results Now that we have all of this data, it's time to take action! Schedule a team meeting with your security leaders and specify which vulnerabilities need immediate attention. Your pen testers should provide you with: How the vulnerabilities were discovered Potential outcomes if they are exploited The risk level for each vulnerability Remediation advice The tester will use their technical expertise to determine the most pressing vulnerabilities. You should review their prioritization and decide which ones make the most critical impact on your business to tackle first. Ask yourself: Should we fix this? What happens if I don't? How will that affect my company? If we can't fix the vulnerability, can we mitigate the damage if exploited? Remember, defects may arise from mistakes made during design or implementation, new attack techniques that were unknown at the time of testing, or simply coding errors. Your development team needs to identify areas where they can improve their process for them to have successful products. Pro Tip: When selecting a pen tester, make sure their reports include both technical and non-technical terms so that your entire team has access to this information. If the report is too complex for audiences outside of tech-related fields, it may not provide enough information needed to justify adjustments within an organization's business practices.8. Review Vulnerabilities and Adapt After you've prioritized your results, you'll begin remediation. During this process, we recommend: Keep communication channels open by providing regular feedback and being available for quick meetings to provide clarity or address questions and concerns. Assign a dedicated task force to handle any uncovered vulnerabilities, ensuring they have all the resources necessary and an appropriate amount of time and experience for this job. Identify the root cause of the vulnerability and develop strategies to take corrective action for each one. Re-evaluate your security measures after they have been fixed to ensure that any previously found vulnerabilities were indeed eliminated. Maximize Your Security Posture While penetration tests are a great way to identify vulnerabilities, they have clear limitations. The main one is that it only captures a snapshot of a specific point in time. To get the most out of your security processes, you need to pair it with a robust security partner that has the ability to test your system and processes continually. APIsec offers a fully automated and continuous testing solution that runs comprehensive attacks on every endpoint in your network—giving you the most up-to-date information. Ready to start securing your APIs and networks?

What is Business Constraint Exploitation?

Business constraint exploitation, commonly known as business constraint bypass, is not a typical data breach where sensitive data is stolen; rather, this vulnerability occurs when an application's business logic constraints are circumvented by an attacker. Since this flaw is more challenging to discover than OWASP vulnerabilities, we've put together an article that discusses the importance of identifying it and what you can do to test for potential attacks. Why It's Important to Identify Business Constraint Bypass? Business Constraint Bypass is an overlooked threat that can seem harmless at first. But if left unchecked, this simple exploit could lead to serious problems for your company's data and applications—from getting access where it shouldn't have to DoS-based attacks. For example, your website has a flash sale of a product, but each customer is limited to 10 items per transaction. When a web application or an API has a loophole, malicious users are given carte blanche to modify and exploit this parameter (limit per customer to purchase more, therefore bypassing your business constraint. If you've tried to get your hands on a new gaming system during its initial launch, you've experienced this type of exploit from a customer's perspective. Let's see ways to correct business constraint exploitations. How to Combat Business Constraint Bypass Vulnerabilities? The best way to get more information from a program is by looking at its controller. This can be done in two ways: finding parameters that may be changed or examined and then modifying them to have better data sets for your analysis. Modifying a program's parameters to return more data than necessary is an effective way of finding bugs in the application. Usually, this involves looking at all its possibilities and then choosing which ones can be modified for better results. Here are some other remediation steps you could take: Monitor API Calls: Make sure they are being used as intended. If an API call is available on the internet, someone has a chance to exploit it. Set Limits on API Keys: Regular users should never have limitless capabilities or access. Set User Limits on Dynamic APIs: Limit requests by user or use cases, including session data in requests themselves. Observe HTTP Traffic: Look at both request and response blocks. Analyze POST/GET Requests: Malicious actors might use POST/GET requests with typical parameters either in name-value pair, JSON, or XML. Search Hidden Parameters: Look for hidden parameters and their values, analyzing specific calls as these constraints on a business can become targets if the end-user of your application or website does not understand them. Start Securing Your Business Constraints with APIsec Finding business constraints on your own is time-consuming, and you still risk missing a flaw. APIsec is leading the industry with its innovative, comprehensive, and continuous API testing. Here's how they find the often undiscovered constraint flaws: API Analyzer: With API Analyzer, you can dissect your company's APIs down to every endpoint, call, and input parameter so that the engine knows how best to attack it.

Web Attacks: Intro to HTTP Verb Tampering

In the early days of the internet, you had to type "http://" before entering the web address of a website. Redirects have made our lives easier in that sense, but HTTP (Hypertext Transfer Protocol) still plays an integral part in applications across the web. Since this application-layer protocol for transferring hypermedia documents, such as HTML to render pages, is so common — it’s also a popular attack vector for cybercriminals. What Are HTTP Verbs? The HTTP verbs specify how the server should handle data identified by the URL. Often called "HTTP methods," they're called verbs because they are simply actions. Web servers accept many different HTTP verbs, but some of the most common instances are: GET - Returns a representation of a specified resource. Only retrieves data. POST - Submits an entity to the specified resource, often causing a change in state or side effects on the server. PUT- Writes the request payload to the specified location. PATCH - Makes a partial change to an existing resource. DELETE - Deletes the resource at the specified location. GET and POST are traditionally the two most commonly used HTTP verbs. For example, when you want to visit a website like Google, you’re performing a GET HTTP verb, retrieving the data from the website to your device. Performing a POST HTTP verb often shows up as entering information into a form on a website. You're "posting" new data, or a state change, on the web server. Links with the standard style trigger a GET request, while forms submitted with the 'POST' method trigger a POST request. In the absence of an HTTP verb, the form sends data via GET by default. As you can see, there’s not much difficulty in being able to change HTTP verb inputs. Attackers easily perform sensitive functions like DELETE once it's evident that there are vulnerabilities in the HTTP configuration. How Does HTTP Verb Tampering Work? HTTP verb tampering attacks take advantage of vulnerabilities in authentication and access control mechanisms of HTTP methods. The most common HTTP methods allow access with limited security because that’s how the authentication mechanisms were intended. Sites that required authentication originally were deemed secure with only password protection. As the Web got smarter, so did cybercriminals. Because most HTTP verbs are not fully secure, tampering is as simple as manipulating a password-protected area, allowing unauthorized access to restricted resources. HTTP verb tampering tends to be caused by misconfigured security settings either in the web application or the backend server. An attacker will exploit the vulnerability to bypass authentication and access sensitive data—with the option to manipulate or delete data by simply changing the request method. Common Attack Scenarios Insecure default configurations: Analyze whether any of your endpoints run on out-of-the-box settings and allow the usage of all HTTP verbs by default. Storing HTTP verbs in URL strings: Attackers can extract which HTTP verbs are allowed if stored in the URL strings. Ensure that your URLs do not contain HTTP verbs that can allow the URL to be easily manipulated. Using hidden fields to store status information: Hidden fields might be great and easy to use at design time, but attackers can easily read those hidden fields by inspecting the web page and then tamper with the information in them. Man-in-the-Middle attacks: Two servers are communicating without encryption, which allows an attacker to intercept and monitor traffic and communication. Lack of authorization and authentication of API endpoints: API vulnerabilities are commonly caused by inadequate authorization and authentication controls. An attacker can compromise an account protected by a single layer of authentication and abuse a lack of checks to expose information. Insecure coding: A web developer often applies specific filters to mitigate particular vulnerabilities within the written code, but leaves the code insecure by not applying those filters to all HTTP verbs. HTTP verbs being transferred between the client and the server: An attacker hijacks the message being passed between client and server to tweak the HTTP verb. How to Combat HTTP Verb Tampering Vulnerabilities There are a few actions you should take immediately to prevent HTTP verb tampering. Check Configurations: Make sure your code is not set to "allow all" in your security configurations. Failure to do so means attackers can use alternative HTTP verbs like HEAD or arbitrary character strings in their requests to gain access. Test: Penetration testing (or pen testing) involves simulating attack scenarios on your HTTP verbs to look for vulnerabilities that could lead to HTTP verb tampering before they're exploited. If you're regularly conducting pen tests, checking for problems like modified data or request smuggling will help prevent any issues from happening later. Be sure to include not only whether or not they're accessible, but what may happen once access has been granted. Automate the process: Automation saves time and resources all around. Automating your pen-testing means more quality analysis in finding potential vulnerabilities and preventing them before they happen. APIsec is the only automated API security testing solution that covers both vulnerability scanning and pen testing. APIsec provides ten times the coverage of manual pen testing at one-tenth the cost. APIsec doesn’t stop there, though. When vulnerabilities are uncovered, APIsec automatically provides a detailed description of the attack playbook used, giving you an actual "recording" or wire logs of the successful attack and remediation recommendations. Engineers never have to waste time investigating issues; instead, they can focus on remediation of the underlying problem.

Sensitive Data Exposure: What It Is and How to Avoid It

The amount of sensitive data we share with outsiders has skyrocketed thanks to the technological advances that undoubtedly make our lives easier. However, these same advancements come with a cost—increasing exposure of our personal data. So, how is sensitive data exposed? What Is Sensitive Data Exposure? A sensitive data exposure occurs when an organization unknowingly exposes its customers' private information, leading to accidental destruction, alteration, or distribution of sensitive data. Personally identifiable information (PII) such as financial, business, and personal data is not the only sensitive information that needs to be protected. Other forms of sensitive data that need rigorous safeguarding include: Race, ethnicity, religious beliefs, political associations, or philosophical beliefs Passwords/login credentials Genetic and biometric data Trade-union membership Health-related information Details surrounding an individual's sex life or sexual orientation Sensitive Data Exposure vs. Data Breach It's important to remember that sensitive data exposure is different from a data breach, even though these terms are often used interchangeably. A data breach occurs when a third party with malicious intent gains unauthorized access to sensitive information. This typically occurs when sensitive data is exposed; however, breaches still happen without a preexisting exposure. On the other hand, it's possible for an organization to have sensitive data exposure without having their information breached. Just because an exposure exists doesn't mean it will be breached, but it significantly increases the chances. How Do Sensitive Data Exposures Lead to Attacks? The more you know about how data is prone to exposure, the better equipped your organization will be at mitigating potential attacks on this sensitive information. And since regulations, like the GDPR and CCAP, require organizations to protect sensitive data or face serious consequences, it's essential to know specifically where your company's sensitive files may run into trouble. Digital data is found in several different states, and to better understand where attacks occur, we need to take a quick look at them first. Data at Rest Many web applications typically store data at rest in servers, files, networks, and databases. While this data appears to be less vulnerable to attacks, the security of this information is entirely dependent on the protocols in place to protect it. Cyberattacks such as SQL injections or malicious payloads are used to circumvent security measures and gain unauthorized access to stored data. Data in Motion As data is exchanged between servers, channels, and application programming interfaces (APIs), it's at risk of interception by third parties along the way. Cybercriminals take advantage of security flaws that exist when two applications or servers communicate without encryption. One common attack is known as a man-in-the-middle (MITM), where the attacker intercepts and monitors traffic and communication. Data in Use Unlike data in motion or rest, data in use is a reflection of the current activity happening within an organization's IT infrastructure. This means that it can be actively updated, processed, or erased at any time, rather than simply being stored for later access. Data in this state is equally vulnerable to attacks and even more likely to be initiated by insider attacks. Now that you know where data can be attacked, let’s look at the way these attacks happen. Common Ways Data is Infiltrated: Broken access controls - Broken access control attacks rank #1 on OWASP's Top 10 list for web applications in 2021 and occur when an unauthorized user breaks through preexisting security barriers put in place to protect your data and applications. Weak or missing TSL/HTTPS - Lack of or weak encryptions is also a major cause of sensitive data exposure. Storing plain text files containing personal information onto your website leaves it vulnerable to exploits. SQL injection flaw - SQL injections occur when attackers introduce malicious queries into the system to extract information about users or other important details with a simple command. Phishing - Phishing attacks are designed to mislead users and get them to provide sensitive information via emails, instant messages, and text messages. Insider attacks - Insider attacks occur when current or former employees with authorized access initiate an attack by breaking in and stealing data, often going unnoticed because most organizations focus on outside attacks rather than those coming from within. How to Prevent Sensitive Data Exposure While web applications and web surfaces have their own vulnerabilities, however, Gartner predicts that APIs will be the main attack vector by 2022. To help prevent exposures, OWASP suggests you take these minimum steps against cryptographic failures (another name for sensitive data exposure). Identify, filter, and classify client data Avoid storing non-essential data Encrypt data at rest Update algorithms regularly Encrypt data in transit (with TSL) Disable caching for sensitive data Enforce authorization for all APIs (even internal) Address excessive data exposure vulnerabilities While these steps offer a great starting point, taking advanced measures will ensure your data is well protected. We recommend taking some advanced security measures. Advanced Recommendations Automated security - Use an automated end-to-end vulnerability scanning solution to improve your security posture by benchmarking web applications against the OWASP Top 10 list. Automated API testing platforms detect potential problems before they grow into something major. Continuous testing - Integrating security into software that includes continuous testing from development through production gives you complete coverage and ensures there are no loopholes for attackers to exploit.. As the world continues to accelerate development cycles, organizations should never compromise security to meet the demands of digital transformation. With APIsec, you won't have to. APIsec is the only platform that offers an automated, comprehensive way to test your company's API security. With ten times the coverage of manual pen testing, APIsec enables in-depth security assessments for your entire breadth of APIs. The automated platform tests against both known vulnerabilities and newly found threats to give you peace of mind with every vulnerability test.

Generating OpenAPI Specification (OAS) documentation for your REST APIs

The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.[1] APISec supports 1.0, 2.0, 3.x versions of the OpenAPI specification (OAS) as well as Postman and RAML formats. The following is a list of some libraries and resources which can be helpful in generating an OpenAPI Specification (OAS) document for your existing REST API application grouped by implementation technology.

How to Address Business Logic Flaws During Application Design

Business logic vulnerabilities often go undetected for years. Nothing makes cybercriminals happier than an application with vulnerabilities they can exploit without any special tools—simply working within the normal functionality of the app. Since most vulnerabilities are exposed in the development phase, catching them during the design phase will require new strategies beyond what has been the industry norm. “Without proper testing, you’re leaving those APIs exposed and just ripe for the picking.” - Corey Ball, Cybersecurity Consulting Manager & Author of "Hacking APIs" We’ve identified common business logic flaws and provided our top tips for eliminating them during application design. 1. Ensure Proper Authorization and Authentication Measures From Day 1 Attackers often gain access to sensitive data through vulnerabilities in authentication and authorization resources that they should not have access to. Here are the most common business logic flaws associated with this cluster of API threats and how you address them from the start: Unprotected APIs: Implement stringent authorization and authentication for all internal and staging APIs so they can’t be compromised to pivot to other systems. Weak credential policy: Restrict the use of insecure or previously exposed passwords to guard yourself against automated brute force attacks. Flawed credential recovery process: Ensure that permit recovery or credential reset can’t be triggered with insufficient information. Broken authentication: Make it impossible to view, modify, or remove the data of another account without the corresponding user privileges. Read More: API Security Checklist: What You Need To Know 2. Eliminate Data Input And Client-Side Loopholes Malicious attackers can alter a database query without using any exploits to make the application execute unauthorized commands. To combat this, we recommend evaluating the most common business logic flaws related to data input and client-side vulnerabilities. Critical parameter manipulation: Inspect HTTP request parameters (the values sent in the request body) to make it impossible to tamper them to query the database. Cookie tampering: Encrypt session and cookie data to prevent the attacker from reverse engineering business logic and modifying cookie parameters to launch a privilege escalation attack. LDAP injection attacks: Check LDAP parameters for any business logic flags to prevent bad actors from changing them to bypass the business layer. Client-side vulnerabilities: Examine your business routines embedded in JavaScript, Flash, or other client-side languages. Read More: Drilling Down Into Excessive Data Exposure: How to Protect Your APIs Sensitive Data 3. Eliminate Logic Flaws From Processes and Workflows When application workflows or processes have design flaws built into the business logic, users short-circuit them in unintended ways to bypass security checks and gain unauthorized access to data and functionalities. That’s why it's essential to meticulously test every action and task the user can perform to uncover potential loopholes. These business logic vulnerabilities would be a great starting point: Business constraint exploitation: Ensure that no hidden user fields contain values that control the constraints or restrictions defined by the business logic layer. Business flow bypass: Break down your application workflows to verify steps can’t be hijacked, skipped, or bypassed to perform a certain task. Denial of Services (DoS) with business logic: Check for the possibility of short-circuiting processes with infinite loops to overload or crash the system. Auto-increment IDs: Graduate from using automatically-incrementing identifiers when generating database records to make it impossible for the attacker to automatically harvest all of your records should you find your defense lines compromised. Read More: What Is API Privacy and How to Protect Your Sensitive Data 4. Ensure Critical Data Is Secured APIs and web applications often leak credentials and sensitive data without an organization ever knowing it happened. By following these best practices, you help to ensure that your API is secure: Identity extraction: Examine the parameters that control user profiles and make it impossible for the attacker to reverse engineer or guess tokens to harvest user data. Getting entire database objects: Ensure that the server returns only the values requested by the user, not entire database objects. Never leave data filtering to the client. Unauthorized file URL access: Dissect the mechanisms that generate temporary links to restricted files to ensure they can’t be reverse-engineered or hijacked with a custom API call. Read More: How Improper Assets Management Leaves Your APIs Vulnerable to Attacks The Only Automated API Security Testing Tool that Detects Business Logic Flaws Armed with this list, you will drastically reduce the likelihood and severity of data breaches caused by this vulnerability cluster. APIsec is the only fully automated API security testing solution that identifies business logic vulnerabilities at scale.
