Security Testing Fundamentals Questions

Fundamental practices for identifying and mitigating security vulnerabilities in software. Candidates should understand common failure modes described by the Open Web Application Security Project Top Ten and related risks such as injection attacks including structured query language injection, cross site scripting, broken authentication and authorization, insecure direct object references, and security misconfiguration. Coverage includes secure coding patterns such as input validation, output encoding, parameterized queries, secure session handling, least privilege, and secret management. Testing approaches include manual exploratory security testing, threat modeling, dynamic security scanning, static analysis, dependency and composition analysis, fuzz testing, and targeted penetration testing. Candidates should also be able to explain how to integrate security checks into automated test suites and continuous integration pipelines and how to prioritize security fixes by impact and exploitability.
