The ESXi host must exclusively enable TLS 1.2 for all endpoints.
Description
Discussion Text
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 the third-party software supports TLS 1.2.
Be sure to modify TLS settings in the following order:
1. Platform Services Controllers (if applicable)
2. vCenter
3. ESXi
