How do you test for security vulnerabilities in software?

H2K Infosys emphasizes that QA testing for security vulnerabilities in software requires a multi-layered approach. Begin with threat modeling to identify risks, followed by static and dynamic code analysis. Perform penetration testing to simulate real-world attacks, and use automated vulnerability scanning tools regularly. Secure code reviews and dependency checks help detect hidden issues. Additionally, conduct compliance testing against standards like OWASP Top 10. Continuous integration pipelines should include security testing, ensuring vulnerabilities are identified early and resolved promptly before deployment. Regular monitoring and incident response planning further strengthen application security posture over time, reducing risk of breaches significantly for organizations globally.
