Ensure dhcp relay services are not in use

OrtaDüzey 1Otomatikaix

Açıklama

The dhcprd daemon listens for broadcast packets, receives them, and forwards them to the appropriate DHCP or BOOTP server. Unless a system is specifically set up to act as a DHCP relay server, it is recommended that the dhcpd fileset be removed to reduce the potential attack surface. Audit: the dhcprd start line in /etc/rc.tcpip must be commented out and the dhcprd subsystem must not be active.

Nasıl denetlenir

Denetim yöntemi: Kabuk komutu

shell

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

Beklenen çıktı: compliant
