Study Notes
Digital User Authentication Principles
- Digital identity is a unique representation of a subject in online transactions (NIST SP 800-63-3).
- Digital user authentication determines the validity of authenticators claiming a digital identity.
- Basic security requirements include identifying users, authenticating identities, and employing multifactor authentication (MFA).
Password-Based Authentication
- Requires users to authenticate with something they know, such as a password or PIN.
- Security measures include enforcing complexity, preventing reuse, and disabling inactive accounts.
Token-Based Authentication
- Users authenticate with something they possess, like a smartcard or electronic keycard.
- One-time passwords (OTP) generated by devices increase security for transactions.
- Alternatives like time-based OTP (TOTP) rely on algorithms and a secure clock, but vulnerable to clock drift issues.
Biometric Authentication
- Utilizes unique physical characteristics (e.g., fingerprints, facial recognition) for user authentication.
- Technically complex and expensive compared to traditional methods, yet provides heightened security.
Multifactor Authentication (MFA)
- MFA involves using two or more factors for identity verification, such as passwords combined with tokens or biometrics.
- Enhances security compared to single-factor authentication methods.
Assurance Levels for User Authentication
- Identity Assurance Levels (IAL) define certainty in identity proofing:
- IAL1: No link to real identity required.
- IAL2: Evidence of identity through remote or in-person proofing.
- IAL3: Physical presence is needed for proofing.
- Authenticator Assurance Levels (AAL) gauge authentication strength:
- AAL1: User ID and password provide some assurance.
- Higher levels require stronger proof mechanisms.
Security Issues for User Authentication
- User authentication is subject to attacks like eavesdropping, replay attacks, and client/host attacks.
- Common attacks include password guessing, token theft, and biometric spoofing.
- Defense strategies involve multifactor authentication, large entropy for identifiers, and rigorous password protection measures.
Remote User Authentication Challenges
- Increased complexity and vulnerability over networks due to threats like capturing passwords and replaying authentication sequences.
- Challenge-response protocols can mitigate some security risks associated with remote authentication.
Case Study: ATM Security Problems
- Small to mid-sized debit card issuers often rely on processors for core data processing and electronic funds transfer, leading to potential vulnerabilities in ATM security.
