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 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 allows developers to identify and fix problems during the coding process rather than after deployment. It reduces both cost and risks. Q: What role do containers play in application security? Containers offer isolation and consistency between development and production environments but also present unique security challenges. Organizations must implement container-specific security measures including image scanning, runtime protection, and proper configuration management to prevent vulnerabilities from propagating through containerized applications. Q: What is the difference between a vulnerability that can be exploited and one that can only be "theorized"? 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. Q: Why is API security becoming more critical in modern applications? A: APIs are the connecting tissue between modern apps, which mak
