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.
