AppSec Q and A

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. 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 tests include static analysis (SAST), interactive testing (IAST), and dynamic analysis (DAST). This allows for comprehensive coverage throughout the software development cycle.

Q: How can organizations effectively manage secrets in their applications?

A: Secrets management requires a systematic approach to storing, distributing, and rotating sensitive information like API keys, passwords, and certificates. Best practices include using dedicated secrets management tools, implementing strict access controls, and regularly rotating credentials to minimize the risk of exposure.

Q: Why does API security become more important in modern applications today?
