A: Application security testing identifies vulnerabilities in software applications before they can be exploited. In today's rapid development environments, it's essential because a single vulnerability can expose sensitive data or allow system compromise. Modern AppSec testing includes static analysis (SAST), dynamic analysis (DAST), and interactive testing (IAST) to provide comprehensive coverage across the software development lifecycle.
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 allows developers to identify and fix problems during the coding process rather than after deployment. It reduces both cost and risks.
