Study Notes
Multi-Factor Authentication (MFA)
- MFA is an authentication method that requires more than one method to identify a user.
- It can be based on what you know (e.g., a password and username), what you have (e.g., a phone or a security key), or what you are (e.g., a fingerprint scan).
- MFA is a good defense against account hacks, but it has its own pitfalls, such as losing your phone or SIM card.
- Adding a recovery phone number to your Google account can prevent phishing attacks and automated bots while enabling MFA on Microsoft accounts blocks 99.9% of unauthorized login attempts.
Certificate-Based Authentication
- Uses digital certificates (like a driver's license) that contain the user's identity, including a public key.
- Certificate is issued and signed by a certification authority to prove ownership of a public key.
- Users provide their digital certificate to sign into a server, which verifies the signature and the certificate authority; then uses cryptography to confirm the user has the correct private key associated with the certificate.
Biometric Authentication
- Uses unique biological characteristics for authentication.
- Examples include fingerprint scanners, facial recognition, iris scanners and voice recognition.
- Advantages include easy comparison to authorized features in a database, physical access control for gates and doors, and integration into multi-factor authentication.
- Widely used by airports, military bases, government agencies and corporations.
Passphrases
- A passphrase is a longer, sentence-like sequence of words for authentication.
- Typical passwords are between 8-16 characters, while passphrases can exceed 100 characters long.
Challenge-Response Authentication
- A set of protocols that validate actions to prevent unauthorized access.
- Requires a verifier to present a challenge to the user who must provide the correct answer.
- Can be as simple as a password or dynamically generated request.
Security Tokens
- Physical devices used as hardware authenticators.
- Contain cryptographic information specific to each user, used for authentication.
- Examples include USB keys, name badges with chips, and car remotes.
- Can substitute passwords or be used as an additional factor in MFA.
- Considered a "possession" factor in MFA.
