performing-web-application-penetration-test
Performs systematic security testing of web applications following the OWASP Web Security Testing Guide (WSTG) methodology to identify vulnerabilities in authentication, authorization, input validation, session management, and business logic. The tester uses Burp Suite as the primary interception proxy alongside manual testing techniques to find flaws that automated scanners miss. Activates for requests involving web app pentest, OWASP testing, application security assessment, or web vulnerability testing.

# Performing Web Application Penetration Test
## When to Use
- Testing web applications before production deployment to identify exploitable vulnerabilities
- Conducting compliance-driven security assessments (PCI-DSS requirement 6.6, SOC 2 Type II)
- Validating remediation of previously identified web application vulnerabilities during retesting
- Assessing third-party web applications before integration into the organization's environment
- Evaluating custom-developed web applications where automated scanning alone is insufficient
**Do not use** against web applications without written authorization, against production systems during peak traffic hours without explicit approval, or for denial-of-service testing of web infrastructure.
## Most Often Missed & How to Confirm
- **Authorization beyond the scanner** — IDOR/BOLA and vertical privilege escalation are the most impactful and least scanner-detectable. Replay every object-bearing and state-changing request with a second account and a lower-privilege token (Burp Autorize), including write/delete methods and nested resources.
