Domain Security Best Practices: Preventing Hijacking, DNS Poisoning & Unauthorized Transfers

Hardware 2FA Keys, Registry Locks, DNSSEC and Account Hardening

Key Takeaways

  • Your domain registrar account is the single most critical asset in your digital infrastructure.
  • Hardware security keys (FIDO2 / WebAuthn / YubiKey) eliminate the risk of SMS and phishing attacks.
  • DNSSEC cryptographically signs DNS records to prevent man-in-the-middle DNS cache poisoning.
  • Registry Lock provides the highest security tier by requiring offline human authorization for modifications.

Core Domain Protection Protocols

1. Deploy FIDO2 hardware security keys for two-factor authentication.

2. Enable DNSSEC at both your DNS host and your registrar to prevent cache poisoning.

3. For high-value enterprise domains, activate a Registry Lock directly with Verisign or the authoritative registry.
