What stages are included in the security testing process and how is it implemented in practice?

The security testing process includes several key stages:

1. Security requirements analysis — studying the security requirements of the application or system.
2. Test planning — defining the goals, methods, and tools for security verification.
3. Test environment preparation — creating an environment as close to the operational one as possible, with necessary configurations.
4. Conducting security tests — performing various types of testing, such as:
   • Vulnerability scanning
   • Penetration testing
   • Authentication and authorization testing
   • Attack resilience testing (e.g., DoS)
5. Results analysis — identifying and classifying vulnerabilities.
6. Reporting and recommendations — documenting found issues and suggestions for their resolution.
7. Re-testing — verifying fixes and improvements.

In practice, this is implemented using specialized tools (e.g., OWASP ZAP, Burp Suite), automated scanners, and manual analysis. In DevOps processes, security testing is integrated into CI/CD pipelines for continuous security quality control.
