The Windows DNS Server permissions must be set so the key file can only be read or modified by the account that runs the name server software.
An XCCDF Rule
Description
<VulnDiscussion>To enable zone transfer (requests and responses) through authenticated messages, it is necessary to generate a key for every pair of name servers. The key can also be used for securing other transactions, such as dynamic updates, DNS queries, and responses. The binary key string that is generated by most key generation utilities used with DNSSEC is Base64 encoded. Transaction Signature (TSIG) is a string used to generate the message authentication hash stored in a TSIG Resource Record (RR) and used to authenticate an entire DNS message.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
