Users with unrestricted access permissions to files and folders are the ultimate target for cyber-criminals. If such accounts are compromised, then the attacker effectively holds the keys to your kingdom. Continuous tracking of who has access to what on the File server is a vital part of ensuring that your permissions don’t sprawl out of control. In this article, we will go through the manual ways in which changes made to files and folders can be identified. We will also show you how Lepide File Server Auditor (part of Lepide Data Security Platform) handles this task.
How to identify file and folder access permissions natively
Keeping sensitive data under close surveillance helps keep your network infrastructure in a constant state of security. To do this, event-by-event analysis is crucial.
Let’s have a look at the steps you need to take to determine who has access to what on the files or folders in your File server:
- Locate the document for which you want to view the permissions.
- Right-click the folder or file and click “Properties” in the context menu.
- Switch to “Security” tab and click “Advanced”.
- In the “Permissions” tab, you can see the permissions held by users over a particular file or folder.

Lepide File Server Auditor – An easier way to audit your file servers
With a comprehensive auditing solution like Lepide File Server Auditor (part of Lepide Data Security Platform) in place, you can easily analyze current effective permissions held by users on files and folders, as well as modifications made to permissions.
The following screenshots show our “Current permissions” reports, which let you analyze the current permissions set on shared files and folders:
Our solution allows you to view permissions assigned to everyone, filter and sort the reports, identify stale objects and also indicates if the permission inheritance is broken at that level.

Effective permissions on an object are calculated after carefully analyzing and comparing both the NTFS and share permissions applied on it. The screenshot given below allows you to analyze the permission flow for an object:
