The vSphere "TrustedAdmins" group grants additional rights to administer the vSphere Trust Authority feature.
To force accountability and nonrepudiation, the SSO group "TrustedAdmins" must be severely restricted.
From the vSphere Client, go to Administration >> Single Sign On >> Users and Groups >> Groups.
Click the next page arrow until the "TrustedAdmins" group appears.
Click "TrustedAdmins".
Review the members of the group and verify only authorized accounts are present.
Note: These accounts act as root on the Photon operating system and have the ability to severely damage vCenter, inadvertently or otherwise.
If any accounts are present as members of "TrustedAdmins" that are not authorized, this is a finding.
From the vSphere Client, go to Administration >> Single Sign On >> Users and Groups >> Groups.
Click the next page arrow until the "TrustedAdmins" group appears.
Click "TrustedAdmins".
Click the three vertical dots next to the name of each unauthorized account.
Select "Remove Member".
