| If the system needs the portmap service to operate, this is not applicable. The rpcbind program is part of a core Solaris package and cannot be removed. Verify the permissions on the rpcbind file. # ls -lL /usr/sbin/rpcbind If the rpcbind service is not required and the rpcbind file has non-zero permissions, this is a finding. |
