Study Notes
Authentication Methods
- Authentication methods involve verifying a user's identity.
- Three common methods include: something you know (passwords), something you are (biometrics), and something you have (tokens).
Advantages and Disadvantages
-
Something you know:
- Advantage: Convenient, immediate login.
- Disadvantage: Forgetting passwords, susceptibility to phishing.
-
Something you are:
- Advantage: No need to remember passwords, generally secure.
- Disadvantage: Sensor/camera errors, physical limitations (e.g., injury).
-
Something you have:
- Advantage: Secure against password guessing, phishing.
- Disadvantage: Device loss or compromise.
Authentication in Operating Systems
- Password entry during OS login.
- Using authentication during system updates.
- Enabling authentication when using apps external from the OS store.
- Accessing sensitive accounts or administrative controls via secure authentication (e.g., multi-factor authentication)
Attacks on Authentication Methods
- Something you know: Phishing (tricking a user into revealing credentials).
- Something you are: Biometric spoofing (e.g., using a contact lens to mimic eye recognition).
- Something you have: Cloning devices for ATM/security access.
Two-Factor Authentication
- Does protect against many attacks on other methods.
- Helpful second factor methods (e.g., passcodes, security tokens) protect against those attacks.
