Web Security Threats – OWASP Top 10 & Real Use Cases

🌐 The Dark Side of the Web and How to Defend It

Introduction
Every web app is a potential target. OWASP Top 10 provides a battle-tested list of the most dangerous threats.

OWASP Top 10 (with examples)

1. Broken Access Control → Users accessing admin features.
2. Cryptographic Failures → Leaked passwords in plain text.
3. Injection Attacks (SQL, NoSQL, XSS) → Login bypass.
4. Insecure Design → Weak workflows.
5. Security Misconfigurations → Exposed admin panels.
6. Vulnerable & Outdated Components → Unpatched plugins.
7. Identification & Authentication Failures → Weak login.
8. Software & Data Integrity Failures → Supply chain attacks.
9. Security Logging & Monitoring Failures → Blind to breaches.
10. Server-Side Request Forgery (SSRF) → Attacker pivots internally.

Case Studies

• SQL injection in e-commerce → stolen credit cards.
• Misconfigured AWS S3 bucket → millions of records leaked.
• XSS in a banking app → session hijacking.

Conclusion
Your web app is only as strong as its weakest point. Treat OWASP Top 10 as a survival guide, not a checklist.
