When a site is in violation of its assigned policy, that site can be audited. To do so, browse to the [Explorer] tab and scroll to the site you wish to audit. Under "Actions", expand the 3 dots and select "Audit Site".
 

A site auditing wizard will then be launched [To Do], which shows you an overview of all the current policy violations that were detected on that site. For each violation, you are given the option to either:

• Revert the violation to be in line with the policy applied, or 
• Approve the violation and acknowledge it

Clicking on one of the rows will populate a panel showing the violation details.

To view more detailed information about the access permissions of the affected item, expand the 3 dots and select "Permissions". Doing so will populate a panel with information about sharing links, administrators, owners and users with different access permissions. (Can View, Can Edit, etc.)

Note: All actions and changes made will be audit logged and viewable in the Event Log, along with the details of the user account that performed the action.
