Host must deactivate CIM

中レベル 1自動vmware

説明

Deactivating the Common Information Model (CIM) service, when not in use, aligns with the principle of minimizing the attack surface by disabling non-essential services. This action helps in reducing the potential vectors of attack, thus bolstering the host's security posture. The audit runs esxcli system wbem get and requires "Enabled: false". Document an exception when CIM is required. Runs in the ESXi Shell (busybox sh) as root.

監査方法: シェルコマンド

shell

out=$(esxcli system wbem get 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk -F': *' 'tolower($1) ~ /^ *enabled$/ {print $2; exit}' | tr 'A-Z' 'a-z' | sed 's/ *$//')
if [ "$v" = false ]; then echo compliant; else echo "WBEM Enabled: ${v:-not reported}"; fi

期待される出力: compliant
