TMA-ESXI9-3.7

Host must automatically terminate idle DCUI sessions

MediaNivel 1Automatizadavmware

Descripción

By configuring a session timeout, unattended console sessions are automatically terminated, thereby reducing the potential security risks associated with lingering active sessions. The parameter governing this behavior is UserVars.DcuiTimeOut, with a recommended setting of 600 (10 minutes). The audit reads UserVars.DcuiTimeOut with esxcli and requires 600 seconds or less (0 disables the timeout and fails). Runs in the ESXi Shell (busybox sh) as root.

Cómo se verifica

Método de auditoría: Comando de shell

shell
out=$(esxcli system settings advanced list -o /UserVars/DcuiTimeOut 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/UserVars/DcuiTimeOut: no integer value'; exit 1 ;; esac
if [ "$v" -gt 0 ] && [ "$v" -le 600 ]; then echo compliant; else echo "/UserVars/DcuiTimeOut = $v (expected 1-600)"; fi
Salida esperada
compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

To correct the DCUI timeout setting, perform the following steps: 1. From the vSphere Web Client, select the host. 2. Click Configure, then under System select Advanced System Settings. 3. Select Edit then enter UserVars.DcuiTimeOut in the filter. 4. Click in the box for the current value, then set the value to 600 seconds or less. Alternately, use the following PowerCLI command: Get-VMHost | Get-AdvancedSetting -Name UserVars.DcuiTimeOut | Set-AdvancedSetting -Value 600
