The ESXi host must exclusively enable Transport Layer Security (TLS) 1.2 for all endpoints.

Description
TLS 1.0 and 1.1 are deprecated protocols with well-published shortcomings and vulnerabilities. TLS 1.2 should be enabled on all interfaces and SSLv3, TL 1.1, and 1.0 disabled, where supported. Mandating TLS 1.2 may break third-party integrations and add-ons to vSphere. Test these integrations carefully after implementing TLS 1.2 and roll back where appropriate. On interfaces where required functionality is broken with TLS 1.2, this finding is not applicable until such time as the third-party software supports TLS 1.2. Modify TLS settings in the following order: 1. vCenter. 2. ESXi. Satisfies: SRG-OS-000480-VMM-002000, SRG-OS-000425-VMM-001710

Check Text (C-256429r959010_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "UserVars.ESXiVPsDisabledProtocols" value and verify it is set to the following: tlsv1,tlsv1.1,sslv3 or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name UserVars.ESXiVPsDisabledProtocols If the "UserVars.ESXiVPsDisabledProtocols" setting is not set to "tlsv1,tlsv1.1,sslv3" or the setting does not exist, this is a finding.
