OWASP Top 10: A Rogue's Gallery of Web Risks

The OWASP (Open Web Application Security Project) Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications.

While the specific list evolves, common themes include:

1. Injection Flaws (e.g., SQLi, NoSQLi, OS Command Injection)
2. Broken Authentication
3. Sensitive Data Exposure
4. XML External Entities (XXE)
5. Broken Access Control
6. Security Misconfiguration
7. Cross-Site Scripting (XSS)
8. Insecure Deserialization
9. Using Components with Known Vulnerabilities
10. Insufficient Logging & Monitoring

Understanding these risks is the first step to defending against them. We'll dive deeper into many of these throughout this module.
