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 Public Folders. If an attacker were to intrude into an Exchange CA server and be able to access the Public Folder website, it would provide an additional attack vector, provided the virtual directory was present. Once removed, the Public functionality cannot be used without restoring the virtual directory. |
