| Description |
|---|
| All forms of authentication other than Common Access Card (CAC) must be disabled. Password authentication can be temporarily reenabled for emergency access to the local Single Sign-On (SSO) accounts or Active Directory user/pass accounts, but it must be disabled as soon as CAC authentication is functional. |
| ℹ️ Check |
|---|
| If a federated identity provider is configured and used for an identity source, this is not applicable. From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Identity Provider >> Smart Card Authentication. Under "Authentication method", examine the allowed methods. If "Smart card authentication" is not enabled and "Password and windows session authentication" is not disabled, this is a finding. |
| ✔️ Fix |
|---|
| From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Identity Provider >> Smart Card Authentication. Next to "Authentication method", click "Edit". Select to radio button to "Enable smart card authentication". Click "Save". To re-enable password authentication for troubleshooting purposes, run the following command on the vCenter Server Appliance: # /opt/vmware/bin/sso-config.sh -set_authn_policy -pwdAuthn true -winAuthn false -certAuthn false -securIDAuthn false -t vsphere.local |
