Check: Exch-1-603
Exchange 2010 Client Access Server STIG:
Exch-1-603
(in version v1 r9)
Title
The Microsoft Active Sync directory must be removed. (Cat III impact)
Discussion
To reduce the vectors through which a server can be attacked, unneeded application components should be disabled or removed. By default, a virtual directory is installed for Active Sync, and the Exchange application default has Active Sync disabled. If an attacker were to intrude into an Exchange CA server and reactivate Active Sync, this attack vector could once again be open, provided the virtual directory is present. Once removed, the Active Sync functionality cannot be used without restoring the virtual directory, not a trivial process.
Check Content
Open the Exchange Management Shell and enter the following command: Get-ActiveSyncVirtualDirectory | Select Server, Name, Identity, Path If the value of 'Path' (actual directory) exists, this is a finding.
Fix Text
Open an Exchange Command Shell and enter the following command: Remove-ActiveSyncVirtualDirectory ServerName\Microsoft-Server-Active-Sync -Confirm $true NOTE: The physical directory must also be deleted.
