TMA-VMWARE-3.2

Host must deactivate the ESXi shell

AltaNivel 1Automatizadavmware

Descripción

The ESXi shell is an interactive command line environment available from the Direct Console User Interface (DCUI) or remotely via SSH. Activities performed from the ESXi Shell bypass all access controls, but are logged. The recommended setting for the ESXi shell is to be stopped and only started manually when needed, such as when running diagnostics or troubleshooting. The audit parses vim-cmd hostsvc/hostconfig for the TSM (ESXi Shell) service and requires startup policy "off" and the service not running. Runs in the ESXi Shell (busybox sh) as root.

Cómo se verifica

Método de auditoría: Comando de shell

shell
out=$(vim-cmd hostsvc/hostconfig 2>/dev/null) || exit 1
p=$(printf '%s\n' "$out" | awk '/key = "TSM"/{f=1} f && $1=="policy" {v=$3; gsub(/[",]/, "", v); print v; exit}')
r=$(printf '%s\n' "$out" | awk '/key = "TSM"/{f=1} f && $1=="running" {v=$3; gsub(/[",]/, "", v); print v; exit}')
[ -n "$p" ] || { echo 'TSM: service not found in hostconfig'; exit 1; }
if [ "$p" = off ] && [ "$r" != true ]; then echo compliant; else echo "TSM: policy=$p running=$r"; fi
Salida esperada
