Ensure multicast routing is not in use

보통레벨 2자동aix

설명

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.

command -v lssrc >/dev/null 2>&1 || exit 1; [ -r /etc/rc.tcpip ] || exit 1; out=$( { grep -E "^[[:blank:]]*start[[:blank:]]+/usr/(sbin|lib)/mrouted([[:blank:]]|$)" /etc/rc.tcpip; lssrc -s mrouted | awk 'NR>1 && $NF=="active"' ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

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.
