Flashcards: Mastering User Authentication Security — 10 cards

User Authentication — definition?

Verification process to confirm user identity.

Authentication mechanisms — role?

Verify user identity to grant access.

Broken authentication — impact?

Leads to unauthorized access and data breaches.

Common vulnerabilities — example?

Weak passwords, verbose error messages, insecure storage.

Insecure transmission — risk?

Credentials can be intercepted during communication.

Countermeasure — generic error messages?

Prevent information leakage and username enumeration.

Brute force attack — prevention?

Implement account lockout, rate limiting, and monitoring.

Response time — security significance?

Consistent response times prevent timing attacks.

Hashing credentials — best practice?

Use salted hashing to secure stored passwords.

Multi-factor authentication — benefit?

Provides higher security by requiring multiple verification factors.
