Title

Named pipes that can be accessed anonymously must be configured with limited values on domain controllers. (Cat I impact)

Discussion

This is a Category 1 finding due to the potential for gaining unauthorized system access. Pipes are internal system communications processes. They are identified internally by ID numbers that vary between systems. To make access to these processes easier, these pipes are given names that do not vary between systems. This setting controls which of these pipes may be accessed anonymously.
