DNS security best practices to implement now

DNS is critical for network services, translating domain names into IP addresses. Ensuring its security involves basic server management such as hardening the host server, deploying multiple servers, auditing security logs, and limiting access. There should also be a strong disaster recovery plan. The server configurations should implement measures such as DNS forwarding and encryption. Windows administrators should integrate DNS updates into the AD replication process for extra security. DNS filtering and encryption should be used to block malicious sites and protect data integrity.
