Host must automatically terminate idle host client sessions

MoyenneNiveau 1Automatiséevmware

Description

Configuring the host to automatically terminate idle host client sessions helps mitigate security risks associated with unattended sessions, which could potentially be exploited. The recommended setting for this control is a timeout value of 900. The parameter governing this behavior is UserVars.HostClientSessionTimeout. The audit reads UserVars.HostClientSessionTimeout with esxcli and requires 900 seconds or less (0 = unlimited fails). Runs in the ESXi Shell (busybox sh) as root.

Méthode de vérification

Méthode d'audit: Commande shell

shell

out=$(esxcli system settings advanced list -o /UserVars/HostClientSessionTimeout 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/UserVars/HostClientSessionTimeout: no integer value'; exit 1 ;; esac
if [ "$v" -gt 0 ] && [ "$v" -le 900 ]; then echo compliant; else echo "/UserVars/HostClientSessionTimeout = $v (expected 1-900)"; fi

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

1. Set the approved idle timeout with Get-VMHost | Get-AdvancedSetting -Name UserVars.HostClientSessionTimeout | Set-AdvancedSetting -Value <seconds> -Confirm:$false 2. Reconnect to the Host Client and confirm inactive sessions expire as expected.
