Study Notes
Session Management in Web Applications
- The main purpose of session management in web applications is to securely manage user sessions and maintain the integrity of user authentication.
Attacking Session Tokens
- Attack methods for meaningful tokens in web applications include:
- Token prediction attacks
- Session fixation attacks
- Token replay attacks
- Token brute forcing attacks
Weaknesses in Session Token Handling
- 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
Authentication Technologies
- The types of authentication technologies discussed in the text include:
- Single-factor authentication
- Multi-factor authentication
- Token-based authentication
- (NOT) Biometric authentication
Brute Forcing a Login
- The recommended approach for brute forcing a login is to use a slow and distributed pace to avoid IP blocking and rate limiting.
Authentication Security
- Authentication can be the weakest link in a web application's security because a single vulnerability can compromise the entire system.
