Vulnerability discussion

If personnel are not notified of permission events, they will not be aware of possible unsecure situations.

Check content

From the vSphere Client select the vCenter server at the top of the hierarchy and go to >> Alarms >> Definitions. Verify there is an alarm created to alert on permission deletions. or From a PowerCLI command prompt while connected to the vCenter server run the following command: Get-AlarmDefinition | Where {$_.ExtensionData.Info.Expression.Expression.EventTypeId -eq "vim.event.PermissionRemovedEvent"} | Select Name,Enabled,@{N="EventTypeId";E={$_.ExtensionData.Info.Expression.Expression.EventTypeId}} If an alarm is not created to alert on permission deletion events, this is a finding.

Fix text

From the vSphere Client select the vCenter server at the top of the hierarchy and go to >> Alarms >> Definitions >> Right click in the empty space and select New Alarm. On the General tab provide an alarm name and description, Select vCenter for alarm type and "Monitor for specific events occurring on this object", check "Enable this alarm". On the Triggers tab click Add three triggers and in the event column enter "vim.event.PermissionAddedEvent", "vim.event.PermissionRemovedEvent", and "vim.event.PermissionUpdatedEvent" for the three triggers and click OK.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
