Brute-force attacks target logins (DirectAdmin, webmail, WordPress) by guessing passwords. These practical steps help reduce risk without breaking legitimate access.
Start with strong credentials
Use long, unique passwords for DirectAdmin and each mailbox. Avoid reuse across systems.
- Use a password manager
- Prefer 14+ characters
- Rotate credentials after staff changes
Enable two-factor authentication (2FA)
2FA turns a stolen password into an incomplete login. Keep recovery codes offline.
- Use app-based OTP (TOTP)
- Store recovery codes safely
- Require 2FA for admins and resellers
Reduce exposure
Limit who can reach login pages and services.
- Restrict /wp-admin by IP where possible
- Disable unused accounts
- Use HTTPS everywhere
Watch signals
Monitor failed logins and unusual access patterns so you can respond early.
- Check login logs
- Look for repeated attempts
- Block abusive IPs
