The F5 BIG-IP DNS server implementation must validate the binding of the other DNS server's identity to the DNS information for a server-to-server transaction (e.g., zone transfer).
An XCCDF Rule
Description
<VulnDiscussion>Validation of the binding of the information prevents the modification of information between production and review. The validation of bindings can be achieved, for example, by the use of cryptographic checksums. Validations must be performed automatically. DNSSEC and TSIG/SIG(0) technologies are not effective unless the digital signatures they generate are validated to ensure that the information has not been tampered with and that the producer's identity is legitimate.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
