Ensure dhcp server services are not in use

СредњаНиво 1Аутоматскаaix

Опис

The dhcpsd deamon is the DHCP server that serves addresses and configuration information to DHCP clients in the network. Unless a system is specifically set up to act as a DHCP server, it is recommended that the dhcpd fileset be removed to reduce the potential attack surface. Audit: the dhcpsd start line in /etc/rc.tcpip must be commented out and the dhcpsd 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=$( { grep -E "^[[:blank:]]*start[[:blank:]]+/usr/(sbin|lib)/dhcpsd([[:blank:]]|$)" /etc/rc.tcpip; lssrc -s dhcpsd | 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

Метод исправке: Смерница или закрпа инфраструктуре

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