Study Notes

The main purpose of session management in web applications is to securely manage user sessions and maintain the integrity of user authentication.

Attack methods for meaningful tokens in web applications include:
- Token prediction attacks
- Session fixation attacks
- Token replay attacks
- Token brute forcing attacks

Weaknesses in the handling of session tokens throughout their lifecycle include:
- Insecure token generation
- Insufficient token expiration
- Inadequate token validation
- Poor token storage and management

The types of authentication technologies discussed in the text include:
- Single-factor authentication
- Multi-factor authentication
- Token-based authentication
- (NOT) Biometric authentication

The recommended approach for brute forcing a login is to use a slow and distributed pace to avoid IP blocking and rate limiting.

Authentication can be the weakest link in a web application's security because a single vulnerability can compromise the entire system.
