DNSSEC (Domain Name System Security Extensions) enhances DNS security by validating responses. Here are key practices for effective implementation:
1. Enable DNSSEC Signing
- Sign all zones to prevent spoofing and data tampering.
- Use strong cryptographic algorithms like RSA or ECDSA.
- Regularly rotate keys to mitigate risks of key compromise.
2. Validate DNSSEC Chains
- Ensure proper chain of trust with valid parent zone delegations.
- Monitor DNSSEC validation failures for potential DNS poisoning attacks.
- Implement recursive resolver support for full validation.
3. Secure Key Management
- Store private keys securely using hardware security modules (HSMs).
- Use unique key identifiers for each zone.
- Backup keys regularly and restrict access to authorized personnel.
4. Monitor and Audit
- Enable DNSSEC-aware monitoring tools to track anomalies.
- Conduct regular audits of DNSSEC configurations and logs.
- Update DNSSEC records promptly for domain changes.
