The Windows 2012 DNS Server must require devices to re-authenticate for each dynamic update request connection attempt.
Medium Severity
<VulnDiscussion>Without re-authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. In addition to the re-authentication requirements associated with session locks, organizations may require re-authentication 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). So 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>
