3. Broken Auth & JWT Security

3. Broken Auth & JWT Security: Broken Authentication is like an amusement park ticket collector accepting a VIP wristband drawn with crayons (forged JWT token) without verifying

Broken Authentication is like an amusement park ticket collector accepting a VIP wristband drawn with crayons (forged JWT token) without verifying the official stamp.

2 Analogies: Broken Authentication

Brute Force Locksmith

2 Reasonings: Why Authentication Breaks

Vulnerability Simulation

Which part of a JWT token ensures its integrity and prevents tampering?

The Signature part is generated by hashing the header and payload using a secret key. A tampered token will fail signature verification checks.

What configuration prevents brute force attacks on authentication systems?

Adding SSL certificates

Rate Limiting and Account Lockout

Deleting all idle accounts
