NIS server

Vulnerability Assessment Summary
Checks the presence of a RPC service

Detailed Explanation for this Vulnerability Assessment

The remote host is a NIS server. NIS is used to share password files among
the hosts of a given network, which must not be intercepted by a possible hacker.

Usually, the first step of their attack is to acertain whether they are
attacking a NIS server, which make the host a more valuable target.

Since we could acertain that the remote host is a NIS server, they can
acertain too, which is not a good thing.

Solution : filter incoming TCP and UDP traffic to prevent them from connecting
to the portmapper and to the NIS server.
Network Security Threat Level: Low
