Title

Proxy Neighbor Discovery Protocol (NDP) must not be enabled on the system. (Cat II impact)

Discussion

Proxy Neighbor Discovery Protocol (NDP) allows a system to respond to NDP requests on one interface on behalf of hosts connected to another interface. If this function is enabled when not required, addressing information may be leaked between the attached network segments.

Check Content

If the system does not support proxy NDP, this is not applicable. Determine if the system has proxy NDP enabled. If so, this is a finding.

Fix Text

Disable proxy NDP on the system.
