Q: What is Application Security Testing and why is this important 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 testing includes static analysis (SAST), dynamic analysis (DAST), and interactive testing (IAST) to provide comprehensive coverage across the software development lifecycle. Q: What role do containers play in application security? A: Containers provide isolation and consistency across development and production environments, but they introduce 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: How do organizations manage secrets effectively in their applications? Secrets management is a systematized approach that involves storing, disseminating, and rotating sensitive data like API keys and passwords. The best practices are to use dedicated tools for secrets management, implement strict access controls and rotate credentials regularly. Q: What is the difference between a vulnerability that can be exploited and one that can only be “theorized”?
