Ensure CDE is not installed

보통레벨 1자동aix

설명

The recommendation is to de-install CDE aka X11.Dt from the system, assuming that it is not required and is already installed. CDE has a history of security problems and should be disabled. NOTE: If CDE is required, it is vital to patch the software and consider TCP Wrappers to further enhance security. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

shell

command -v lslpp >/dev/null 2>&1 || exit 1; lslpp -L >/dev/null 2>&1 || exit 1; out=$( { lslpp -L | grep -i 'X11.Dt' ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Identity if CDE is already installed: lslpp -L |grep -i X11.Dt If there are CDE filesets installed - de-install them if CDE is not required. For each fileset preview the de-installation: installp -up <fileset name> Review the fileset removal preview output, paying particular attention to the other pre- requisites that will also be removed. Typically only X11.Dt filesets should be de- installed as pre-requisites. Once reviewed, de-install the fileset and pre-requisites: installp -ug <fileset name> NOTE: Repeat until all CDE related filesets are de-installed
