Description
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 OMA, and the Exchange application default has OMA disabled. If an attacker were to intrude into an Exchange Front-End server and reactivate OMA, this attack vector could once again be open, provided the virtual directory were present. Once removed, the OMA functionality cannot be used without restoring the virtual directory, not a trivial process.
