The DNS server implementation must provide protected storage for cryptographic keys with organization-defined safeguards and/or hardware protected key store.

A Trusted Platform Module (TPM) is an example of a hardware-protected data store that can be used to protect cryptographic keys.

Verify the DNS server implementation is configured to provide protected storage for cryptographic keys with organization-defined safeguards and/or hardware protected key store.

If the DNS server implementation is not configured to provide protected storage for cryptographic keys with organization-defined safeguards and/or hardware protected key store, this is a finding.

Configure the DNS server implementation to provide protected storage for cryptographic keys with organization-defined safeguards and/or hardware protected key store.
