Ensure rwhod is not in use
Beschreibung
The rwhod daemon is the remote WHO service, which collects and broadcasts status information to peer servers on the same network. Unless a system is specifically set up to provide WHO services, it is recommended that the rcmd_server fileset be removed to reduce the potential attack surface. Audit: the rwhod start line in /etc/rc.tcpip must be commented out and the rwhod subsystem must not be active.

Behebungsmethode: Anleitung oder Infrastruktur-Patch
Run the following command to remove the software: # /usr/sbin/installp -u bos.net.tcp.rcmd_server bos.net.tcp.server - OR - - IF - the bos.net.tcp.rcmd_server fileset is required as a dependency: Run the following script to stop and disable rwhod #!/usr/bin/ksh DAEMONS="rwhod" for l_daemon in $DAEMONS; do /usr/sbin/chrctcp -d $l_daemon /usr/bin/stopsrc -s $l_daemon done
