Ensure multicast routing is not in use

中等級 2自動化aix

說明

The mrouted daemon is an implementation of the multicast routing protocol. Unless a system is specifically set up to act as a network router, it is recommended that the mrouted daemon is disabled to reduce the potential attack surface. Audit: the mrouted start line in /etc/rc.tcpip must be commented out and the mrouted subsystem must not be active.

Run the following script to stop and disable mrouted #!/usr/bin/ksh DAEMONS="mrouted" for l_daemon in $DAEMONS; do /usr/sbin/chrctcp -d $l_daemon /usr/bin/stopsrc -s $l_daemon done NOTE: mrouted is provided by bos.net.tcp.server_core so it is not possible to remove this fileset.
