Check Text ( C-38111r1_chk )
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 (F-31836r1_fix)
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
