Introduction

Web application security testing is more than just running automated scanners. It requires a structured methodology to uncover logic flaws, race conditions, and complex vulnerabilities that tools often miss.

In this guide, we will walk through a complete testing lifecycle, from initial recon to final report generation.

Phase 1: Reconnaissance using OSINT

Before touching the target, you must understand it.

  • Subdomain Enumeration: Using tools like Amass and Subfinder.
  • Technology Profiling: Identifying the stack with Wappalyzer or BuiltWith.
  • Content Discovery: Finding hidden endpoints with ffuf or dirsearch.

Phase 2: Vulnerability Analysis

Once we have mapped the attack surface, we look for entry points.

OWASP Top 10 Focus

  1. Broken Access Control: Can user A access user B’s data?
  2. Injection: SQLi, NoSQLi, and Command Injection.
  3. SSRF: Can the server be tricked into making internal requests?

Phase 3: Exploitation

Demonstrating the impact. This is where we turn a theoretical risk into a proof of concept (PoC).

Note: Always respect the scope of engagement. Exploitation should demonstrate risk, not cause damage.

Conclusion

Effective security testing is an iterative process. By following a methodology, you ensure coverage and consistency.
