What is the best practice for securing PowerProtect Data Domain in a Dell PowerProtect Cyber Recovery vault?
Within a PowerProtect Cyber Recovery vault, best practice is to restrict remote administrative access to the PowerProtect Data Domain system by disabling SSH on all network interfaces except the one used by a trusted, tightly controlled help desk jump host, reducing the exposed management attack surface while preserving the ability to administer the system when required. Fully blocking HTTP/HTTPS or the DD Boost/replication ports would break required vault replication and management functionality, so selective SSH restriction to a jump host is the recommended control.
