A: Application security testing identifies vulnerabilities in software applications before they can be 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 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 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. This distinction allows teams to prioritize remediation efforts, and allocate resources efficiently. Q: Why does API security become more important in modern applications today? A: APIs serve as the connective tissue between modern applications, making them attractive targets for attackers. To protect against attacks such as injection, credential stuffing and denial-of-service, API security must include authentication, authorization and input validation. How should organizations test for security in microservices? A: Microservices require a comprehensive security testing approach that addresses both individual service vulnerabilities and pot
