Q: What is application security testing and why is it critical for modern development?
Application security testing is a way to identify vulnerabilities in software before they are exploited. It's important to test for vulnerabilities in today's rapid-development environments because even a small vulnerability can allow sensitive data to be exposed or compromise a system. Modern AppSec tests include static analysis (SAST), interactive testing (IAST), and dynamic analysis (DAST). This allows for comprehensive coverage throughout the software development cycle.
Q: How does SAST fit into a DevSecOps pipeline?
A: Static Application Security Testing integrates directly into continuous integration/continuous deployment (CI/CD) pipelines, analyzing source code before compilation to detect security vulnerabilities early in development. This "shift-left" approach helps developers identify and fix issues during coding rather than after deployment, reducing both cost and risk.
Q: What makes a vulnerability "exploitable" versus "theoretical"?
A: An exploitable weakness has a clear path of compromise that attackers could realistically use, whereas theoretical vulnerabilities can have security implications but do not provide practical attack vectors. Understanding this distinction helps teams prioritize remediation efforts and allocate resources effectively.
