Understanding Brute Force Attacks

Protecting Against Password Guessing

Brute force attacks try to guess your password by attempting many combinations.

What is a Brute Force Attack?

Automated scripts try thousands of password combinations against your login page.

How They Work

  • Target common usernames (admin, administrator)
  • Try common passwords first
  • Use dictionary words
  • Try combinations at high speed

Signs of Brute Force Attack

  • Many failed login attempts in logs
  • Slow website performance
  • Account lockouts
  • Security plugin alerts

Protection Measures

  • Limit login attempts: Block IPs after failed tries
  • Use strong passwords: Can't be easily guessed
  • Change default username: Don't use "admin"
  • Enable 2FA: Password alone isn't enough
  • Use CAPTCHA: Block automated attempts

WordPress Protection

Security plugins like Wordfence or iThemes Security can:

  • Limit login attempts
  • Block suspicious IPs
  • Alert you to attacks

DirectAdmin Protection

DirectAdmin has built-in brute force protection that blocks IPs after multiple failed attempts.
