The following table provides more information about each event:. Unfortunately, this is not a one-to-one mapping. Each file action includes many smaller operations that Windows performs, and those smaller operations are the ones logged. Consider this only as a starting point. The analysis above is extremely simplified, and real-world implementation will require more research.
Some areas for further research are:. You may want to review this PowerShell Script which reads Windows events and generates from them meaningful file activity report to get a somewhat less simplified analysis. Pro tip: Varonis has been auditing Windows file servers at petabyte scale for over a decade, with numerous patents related to normalization and analysis. Give it a try to save yourself time figuring out how to parse raw logs. While the Windows file activity events seem comprehensive, there are things that cannot be determined using only the event log.
A few examples are:. If you are going to use the native Windows file auditing, you need to be aware of how much data you are going to collect. Collecting Windows file activity is a massive event flow and the Microsoft event structure, generating many events for a single file action, does not help. Such a collection will require more network bandwidth to transfer events and more storage to keep them. Furthermore, the sophisticated logic required may need a powerful processing unit and a lot of memory.
Varonis records file activity with minimal server and network overhead — enabling better data protection, threat detection, and forensics. An alternative approach for implementing this important security and compliance measure is to use a lightweight agent on each monitored Windows system with a focus on file servers. Varonis processes Windows file activity and translates those events into audit data that you can actually use and understand, and can handle many millions of events per hour on the largest file servers.
Keep in mind that each one of those events in the native Windows auditing would be at least four entries, and all mixed in with all of the other logon and ticket authorization events in the Security Event Log. With Varonis, you can easily filter your search in Event Viewer by user, file server, or folder path. Each moment you waste trying to discover which accounts triggered the ransomware, more files might get encrypted. Audit Flowchart. Flowchart Template For Approval Process.
