Title

The portmap or rpcbind service must not be installed unless needed. (Cat II impact)

Discussion

The portmap and rpcbind services increase the attack surface of the system and should only be used when needed. The portmap or rpcbind services are used by a variety of services using Remote Procedure Calls (RPCs).

Check Content

If the system needs the portmap service to operate, this is not applicable. Consult vendor documentation to determine the name and location of the portmap service. The portmap executable is part of fileset bos.net.tcp.client and is not removable, so this will always be a finding.

Fix Text

If the portmap or rpcbind service is part of a removable package, consult vendor documentation for the procedure to remove the package. If the service cannot be removed, prevent service activation by removing all permissions from the executable. Procedure: # chmod 0000 /usr/sbin/portmap
