File Integrity Monitor (FIM)

In this video, a simple File Integrity Monitor (FIM) is built using PowerShell. This FIM monitors a specific set of files and can detect if any of them have been changed, deleted, or new ones have been added. When any of these events occur, the FIM will send an alert to the user to notify them of the change.
