Deep Dive: Brute Force Attacks
- Method: Systematically trying every possible password combination until finding the correct one
- Dictionary attack variant: Tries common passwords first (password123, qwerty, etc.) - faster than pure brute force
- Time factor: Short simple passwords can be cracked in minutes; long complex passwords take years
- Prevention methods:
- Account lockout: Lock account after X failed attempts (e.g., 3-5 tries)
- Strong passwords: Minimum 12+ characters with mixed case, numbers, symbols
- CAPTCHA: Proves user is human, not automated script
- Rate limiting: Slow down login attempts (delays between tries)
- Multi-factor authentication: Requires second factor even if password is correct
