Host SSH daemon, if enabled, must not permit user environment settings

보통레벨 1자동vmware

설명

Preventing user environment settings in the SSH daemon ensures a consistent and controlled environment, reducing the attack surface by limiting the customization of the SSH environment by users. The audit reads /etc/ssh/sshd_config and requires PermitUserEnvironment no (unset = OpenSSH default no). Runs in the ESXi Shell (busybox sh) as root.

점검 방법

감사 방식: 셸 명령

shell

f=/etc/ssh/sshd_config; [ -r "$f" ] || exit 1
v=$(awk 'tolower($1)=="permituserenvironment" {print tolower($2); exit}' "$f")
case "$v" in '') echo compliant ;; no) echo compliant ;; *) echo "PermitUserEnvironment $v" ;; esac

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

To remediate this recommendation, set PermitUserEnvironment no, restart SSH if authorized, and verify users cannot alter the SSH environment through per-user environment settings.
