Shift-left security refers to integrating security measures early in the software development lifecycle (SDLC). This approach ensures that code and software are evaluated for security vulnerabilities at the earliest stages of development, reducing risks and improving overall security posture.
What is Shift Left Security?
Shift-left security refers to the approach of integrating security testing earlier in the software development lifecycle. In traditional DevOps processes, security checks typically happen after the code is developed and ready for deployment. However, this delayed testing can lead to bottlenecks if vulnerabilities are discovered late.
By shifting security left, organizations incorporate security practices from the planning and coding phases. This early integration involves security modeling, which anticipates potential risks before development progresses.
Shift-left security aligns with DevSecOps principles, encouraging seamless collaboration between development, operations, and security teams to ensure continuous, secure software delivery.
What is Shift Right Security in DevOps?
If shift-left security moves testing earlier in the software development process, shift-right security focuses on monitoring and testing in real-world, production environments. No matter how thorough your testing is during development, real-world usage can reveal issues that weren’t detected before deployment.
Shift-right security involves evaluating an application after it’s live, testing its performance, resilience, and reliability under real conditions. This stage ensures that any lingering vulnerabilities or bugs can be caught and addressed promptly, often through patches or other fixes.
DIfferences between Shift Left Security and Shift Right Security
To illustrate the difference, imagine building a car. Shift-right testing would be like taking the car for a test drive after assembling it to see how it handles on the road. If you notice a problem with the brakes or the steering, you’d need to bring the car back to the workshop to make necessary adjustments.
Shift-left security, on the other hand, would be akin to inspecting the engine and other critical components before fully assembling the car, ensuring that any issues are caught early and worked on immediately. Shift right security might be essential but it is definitely not as cost-effective as shift left security.
If we go back to our car example, not selling faulty cars to your customers is amazing but identifying the faults during production is even better and can help in cutting down costs. That is why we can say that for DevSecOps best practices, it is ideal to use both shift right and shift left security combined together.
Benefits of Shift Left Security
Here’s a closer look at the key benefits of shift-left security:
- Early Detection of Issues: Spotting security issues early on is essential for minimizing risks. By identifying vulnerabilities from the start, teams can address them quickly, reducing the chance of missing critical threats later.
