Penetration Testing discovers system and network security vulnerabilities by simulating real attacks. It is an important means of enterprise security assessment. This article introduces 2026 penetration testing methodology and practice.

Penetration Testing Types

External network penetration testing: Targeting internet-facing assets. Internal network penetration testing: Simulating attackers who have obtained initial access within the network. Web application penetration testing: OWASP Top 10 vulnerability testing. Social engineering testing: Phishing emails, phone, and physical security testing. Red team exercises: Simulating real APT attacks, evaluating detection and response capabilities.

Testing Methodology

OWASP Testing Guide: Web application security testing standard. PTES (Penetration Testing Execution Standard): Complete penetration testing process framework. NIST SP 800-115: Technical security assessment guide.

Conclusion

Penetration testing should be conducted regularly (at least annually) and targeted testing after major infrastructure changes. The value of testing results lies in the subsequent remediation execution, not just the test report itself.
