Study Notes
Authentication
Two-Factor Authentication
- Adds an extra layer of security to the authentication process
- Requires two forms of verification:
- Something you know (password, PIN, etc.)
- Something you have (smart card, token, etc.) or something you are (biometric)
- Examples:
- One-time password (OTP) sent to a mobile device
- Authenticator app that generates a time-based code
Access Control
- Process of controlling and managing access to resources and systems
- Involves:
- Identification: claiming an identity
- Authentication: verifying the claimed identity
- Authorization: determining access rights based on authenticated identity
- Types of access control:
- Mandatory Access Control (MAC): access is determined by a set of rules
- Discretionary Access Control (DAC): access is determined by the owner of the resource
- Role-Based Access Control (RBAC): access is determined by a user's role within an organization
Biometric Authentication
- Uses unique physical or behavioral characteristics to verify identity
- Examples:
- Fingerprint recognition
- Facial recognition
- Iris scanning
- Voice recognition
- Handwriting recognition
- Advantages:
- Unique and difficult to replicate
- Convenient and easy to use
- Challenges:
- Privacy concerns
- Accuracy and reliability issues
- Spoofing attacks (e.g., using fake biometric data)
Single Sign-on (SSO)
- Allows users to access multiple systems or applications with a single set of login credentials
- Benefits:
- Convenience: users only need to remember one set of credentials
- Increased security: reduces the risk of password-related security breaches
- Types of SSO:
- Kerberos-based SSO
- Token-based SSO
- Federated SSO (e.g., using SAML or OpenID Connect)
Password Management
- Best practices for creating and managing passwords:
- Use strong, unique passwords for each account
- Use a password manager to generate and store passwords
- Avoid common passwords and password patterns
- Regularly update and change passwords
- Password storage and security:
- Hashing and salting passwords for secure storage
- Using password-based key derivation functions (PBKDFs) for secure authentication
Test your knowledge of authentication and access control methods, including two-factor authentication, biometric authentication, single sign-on, and password management. Learn about the different types of access control and best practices for creating and managing passwords.
