Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls></description> <reference> <dc:title>DPMS Target Microsoft Windows Server 2016</dc:title> <dc:publisher>DISA</dc:publisher> <dc:type>DPMS Target</dc:type> <dc:subject>Microsoft Windows Server 2016</dc:subject> <dc:identifier>4205</dc:identifier> </reference> <ident system="http://cyber.mil/legacy">SV-87935</ident> <ident system="http://cyber.mil/legacy">V-73283</ident> <ident system="http://cyber.mil/cci">CCI-000016</ident> <fixtext fixref="F-26527r857239_fix">Configure temporary user accounts to automatically expire within 72 hours.

Therefore, emergency account activation may bypass normal account authorization processes. If these accounts are automatically disabled, system maintenance during emergencies may not be possible, thus adversely affecting system availability. Emergency administrator accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts are not subject to automatic termination dates. Emergency accounts are accounts created in response to crisis situations, usually for use by maintenance personnel. The automatic expiration or disabling time period may be extended as needed until the crisis is resolved; however, it must not be extended indefinitely. A permanent account should be established for privileged users who need long-term maintenance accounts. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls></description> <reference> <dc:title>DPMS Target Microsoft Windows Server 2016</dc:title> <dc:publisher>DISA</dc:publisher> <dc:type>DPMS Target</dc:type> <dc:subject>Microsoft Windows Server 2016</dc:subject> <dc:identifier>4205</dc:identifier> </reference> <ident system="http://cyber.mil/legacy">V-73285</ident> <ident system="http://cyber.mil/legacy">SV-87937</ident> <ident system="http://cyber.mil/cci">CCI-001682</ident> <fixtext fixref="F-26528r857242_fix">Remove emergency administrator accounts after a crisis has been resolved or configure the accounts to automatically expire within 72 hours.

Use of a Privileged Access Workstation (PAW) and adherence to the Clean Source principle for administering affected affected servers. ….
