Q: What is application security testing and why is it critical for modern development?
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: What makes a vulnerability "exploitable" versus "theoretical"?
