In this tutorial you will be shown how to configure group policy to track file change events on your windows file server.
In the event of a data breach, businesses often want to know who accessed the data and when. They also want to know what kind of changes were made. With this method you can track file changes in your Windows file server. This will help you prevent insider threats by knowing who is accessing files they don’t need access to. Plus, it can help during data breach investigations by proving who changed what.
