The Windows DNS Server must require devices to reauthenticate for each dynamic update request connection attempt.
Medium Severity
<VulnDiscussion>Without reauthenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. In addition to the reauthentication requirements associated with session locks, organizations may require reauthentication of devices, including but not limited to the following other situations: (i) When authenticators change; (ii) When roles change; (iii) When security categories of information systems change; (iv) After a fixed period of time; or (v) Periodically. DNS does perform server authentication when DNSSEC or TSIG/SIG(0) are used, but this authentication is transactional in nature (each transaction has its own authentication performed). Therefore, this requirement is applicable for every server-to-server transaction request.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
