Host must enable the highest version of TLS supported

MoyenneNiveau 1Automatiséevmware

Description

The host should be configured to operate using the highest version of TLS supported to ensure secure communications. ESXi 8, by default, comes with TLS 1.2 enabled, although re-enabling other protocols is possible if required. Employing the highest version of TLS aids in protecting against known vulnerabilities present in older versions. The audit reads UserVars.ESXiVPsDisabledProtocols with esxcli and requires sslv3, tlsv1 and tlsv1.1 to be listed. Runs in the ESXi Shell (busybox sh) as root.

Méthode de vérification

Méthode d'audit: Commande shell

shell

out=$(esxcli system settings advanced list -o /UserVars/ESXiVPsDisabledProtocols 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | sed -n 's/^ *String Value: *//p' | head -n 1)
if printf "%s" "$v" | tr "A-Z" "a-z" | tr -d " " | tr "," "\n" | grep -qx sslv3 && printf "%s" "$v" | tr "A-Z" "a-z" | tr -d " " | tr "," "\n" | grep -qx tlsv1 && printf "%s" "$v" | tr "A-Z" "a-z" | tr -d " " | tr "," "\n" | grep -qx "tlsv1[.]1"; then echo compliant; else echo "/UserVars/ESXiVPsDisabledProtocols = '$v' (expected sslv3,tlsv1,tlsv1.1 disabled)"; fi

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Disable unsupported/legacy protocol versions using Broadcom-supported TLS configuration procedures for ESXi 8 and dependent services. Test vCenter, backup, monitoring, and API integrations before broad deployment.
