Information
In the vSphere Client, you can create a local or a subscribed content library. By using content libraries, you can store and manage content in one vCenter Server instance. Alternatively, you can distribute content across vCenter Server instances to increase consistency and facilitate the deployment workloads at scale. When publishing a content library it can be protected by requiring authentication for subscribers.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
From the vSphere Client, go to Content Libraries.
Select the target content library.
Select "Actions" then "Edit Settings".
Click the checkbox to "Enable user authentication for access to this content library".
Enter and confirm a password for the content library. Click "OK".
Note: Any subscribed content libraries will need to be updated to enable authentication and provide the password.
