01 - Introduction to Web Application Security & Architecture
Master modern web application security architecture, root cause threat modeling, and production configuration of HTTP Security Headers across Nginx, Caddy, Python, Express, and Go.
02 - XSS and CSRF Masterclass
Deep technical breakdown of Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). Master context-aware escaping, DOM sinks, Anti-CSRF token strategies, SameSite cookies, and multi-language defenses in Python, Node.js, Go, and Java.
03 - SSRF and File Upload Security
Master Server-Side Request Forgery (SSRF) defenses, cloud metadata protection (AWS IMDSv2), DNS rebinding mitigation, unrestricted file upload security pipelines, image re-encoding, and path traversal prevention across Python, Node.js, and Go.
04 - Session Management and Authentication
Master secure session state management, server-side Redis session stores, JWT attack vectors (alg: none, key confusion), cookie security flags (__Host- prefixes), and Session Fixation defenses in Python, Node.js, and Go.
05 - Web Security Scanners and Testing Automation
Master Dynamic Application Security Testing (DAST) and SAST automation using OWASP ZAP, Burp Suite, ProjectDiscovery Nuclei, and Semgrep in CI/CD pipelines.
06 - Hands-on Lab: Web Application Vulnerabilities
A self-contained hands-on lab containing a vulnerable Python Flask application (Stored XSS, File Upload RCE, SSRF, Session Fixation), an automated exploit framework, and a production secure refactor.
07 - References and Security Resources
Comprehensive AppSec Atlas directory of official security standards, RFC specifications, real-world CVE case studies, OWASP cheat sheets, and DAST/SAST tooling documentation.
Web Application Security Handbook
Master modern web application security fundamentals, threat modeling, security headers, injection defenses, session protection, DAST tooling, and hands-on vulnerability labs.
