Ensure rwhod is not in use

СредњаНиво 1Аутоматскаaix

Опис

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.

Метод провере: Команда љуске

shell

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

Очекивани излаз: compliant

Како се исправља
