Host must enable the highest version of TLS supported

中レベル 1自動vmware

説明

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.

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

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.
