STIG Description
This STIG provides focused security requirements for the AD or Active Directory Domain Services (AD DS) element for Windows Servers operating systems. These requirements apply to the forest and can typically be reviewed once per AD Forest. The separate Active Directory Domain STIG contains domain level requirements. Systems must also be reviewed using the applicable Windows STIG. Comments or proposed revisions to this document should be sent via e-mail to the following address: disa.letterkenny.FSO.mbx.stig-customer-support-mailbox@mail.mil.

Finding ID	Severity	Title	Description
V-15372	High	Update access to the directory schema must be restricted to appropriate accounts.	A failure to control update access to the AD Schema object could result in the creation of invalid directory objects and attributes. Applications that rely on AD could fail as a result of invalid...
V-8557	Medium	The Windows Time Service on the forest root PDC Emulator must be configured to acquire its time from an external time source.	When the Windows Time service is used to synchronize time on client computers (workstations and servers) throughout an AD forest, the forest root domain PDC Emulator is the normal default to...
V-8555	Medium	Anonymous Access to AD forest data above the rootDSE level must be disabled.	For Windows Server 2003 or above, the dsHeuristics option can be configured to override the default restriction on anonymous access to AD data above the rootDSE level. Anonymous access to AD data...
V-8527	Low	Changes to the AD schema must be subject to a documented configuration management process.	Poorly planned or implemented changes to the AD schema could cause the applications that rely on AD (such as web and database servers) to operate incorrectly or not all. Improper changes to the...
