Web Application Security — The Test Bench

A hands-on, senior-level course that tests and fixes web application vulnerabilities the professional way: probe a surface safely, read the response, then fix the code and re-test until the flaw is closed. Work every OWASP-class flaw — injection, XSS, broken authentication and access control, SSRF, and misconfiguration — on a real HTTP test bench with real requests and real remediation. Four hands-on activities in every lesson.

What you'll learn

• Run the professional loop — probe safely, read the response, reproduce, fix the class at the code, re-test — under authorization.
• Find and fix injection and XSS with parameterization, safe APIs, and context-aware output encoding plus CSP.
• Harden authentication, sessions, and access control against enumeration, CSRF, IDOR, escalation, and mass assignment.
• Close SSRF, deserialization, upload, and misconfiguration flaws, and run the ongoing security-testing loop.
