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 is the role of containers in application security?

Q: Why is API security becoming more critical in modern applications?
A: APIs are the connecting tissue between modern apps, which makes them an attractive target for attackers. To protect against attacks such as injection, credential stuffing and denial-of-service, API security must include authentication, authorization and input validation.
Q: How should organizations approach security testing for microservices?
this link : Microservices require a comprehensive security testing approach that addresses both individual service vulnerabilities and potential issues in service-to-service communications. This includes API security testing, network segmentation validation, and authentication/authorization testing between services.
Q: What are the key differences between SAST and DAST tools?
DAST simulates attacks to test running applications, while SAST analyses source code but without execution. SAST can find issues earlier but may produce false positives, while DAST finds real exploitable vulnerabilities but only after code is deployable. Both approaches are typically used in a comprehensive security program.
Q: What are the best practices for securing CI/CD pipelines?
A: Secure CI/CD pipelines require strong access controls, encrypted secrets management, signed commits, and automated security testing at each stage. Infrastructure-as-code should also undergo security validation before deployment.
