The widespread adoption of agile development practices, like shift left, has made it possible for IT decision-makers to unlock higher revenues. 83% now implement DevOps strategies to keep their pipelines on track. Let us show you how shift left can help your business and explore some best practices to get you started. Why is Shift Left Beneficial for DevOps? DevOps is all about speed, agility, and efficiency. To achieve these goals, organizations need to shift left. This means moving away from the traditional "waterfall" methodology and towards a more agile approach. A shift left strategy ensures security is taken into account as early in the development lifecycle as possible. There are many benefits to shifting left. Here are the ones with the most impact: Increased Quality The main benefit of shift left is that it reduces the number of defects in a final product, increasing its overall quality. Companies that implemented shift left methods experienced a 45% increase in quality. By identifying and resolving issues early in the development process, before the product is released, there are fewer chances for those defects to make it into the finished product. Enhanced Communication In addition, shift left encourages collaboration and communication among team members. Businesses that use agile methods typically see a 60% improvement in team productivity and a 70% improvement in visibility. By involving testers earlier on, developers can get feedback on their code and make changes accordingly, leading to a more positive and productive development process overall. Faster Time to Market Shift left also helps shorten development timelines. Businesses that implement agile practices, such as shift left, have seen their delivery times quicken by 64%. When defects are discovered early, before they can snowball into larger problems, they are easier to address, which allows development teams to focus on new features and improvements instead of fixing bugs. Reduce Costs Shift left reduces the costs associated with development. The earlier a vulnerability is found in the development process, the cheaper it is to fix. Early identification and resolution of defects eliminates the need to rework code, leading to significant savings for development organizations. DevOps Shift Left Best Practices Shifting left in your DevOps practice can be a challenge, but it's definitely worth doing if you're serious about improving your process. Here are a few tips to help you successfully implement shift left: 1. Collaborate to Create Deployment and Testing Procedures There are many reasons why failures in production often go unnoticed. One of the most common is that developers and operations teams use procedures and tools that differ from one another. To be successful, operations and development need a shared understanding of deployment procedures. Having your teams aligned will enable them to detect and resolve issues more quickly and efficiently. 2. Implement Shift Left Gradually There's no one-size-fits-all answer on to how best to implement a shift left strategy within your organization; however, we recommend starting small and gradually increasing the scope and depth of your shift left efforts over time. One way to do this is to start by identifying areas with a high level of waste or inefficiency. These are typically areas where manual processes are still being used when automated ones would be more effective, such as penetration testing. Once you've identified these areas, you can begin to implement shift left principles in a way that makes sense for your organization. 3. Simulate Production Environments Throughout the SDLC The more similar the development and production environments are, the easier it is to avoid errors. You can simulate a production environment with the right patterns and cloud technologies. 4. Test Early and Often Testing is an essential part of quality assurance, and it needs to happen throughout the development process. Continuous testing allows you to find issues sooner, so fixing them will be less costly. 5. Use Automation to Implement Continuous Integration and Delivery CI/CD automates the software development process so that changes are made and tested more quickly. This means that issues are found and fixed earlier in the development cycle before they cause problems in production. The more automation teams incorporate during the coding and deployment phases, the faster they can develop code, run more tests, integrate changes, and spend less time on each activity. There are three common types of automated tests: API tests: API tests include integration tests that check whether an API works as expected in terms of security, functionality, reliability, and performance. Unit tests: Unit tests are a great way to ensure your code works as expected within a specific environment. User interface tests: This is a technique for identifying defects in software utilizing graphics by testing the GUI.

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.

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.

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.
