And contextualization of an event can be very critical, more often than not (even chatGPT thinks so).įigure 1: ChatGPT on FIM.

This provides an advantage of not having to install a kernel component (like a mini-filter driver) but that comes at a cost of missing important context around the event. The reason for that being ‘under-the-hoods’ implementation of the table as it relies on monitoring NTFS journal. It also lacks a unique file identifier like file hash (e.g. Unfortunately, it doesn’t provide any info on which process did the action. Looking at the schema of the ntfs_journal_events, it gives a detailed information on the target file and the type of modification event. There are limitations to what osquery can achieve. This table provides monitoring capabilities for file system events on Windows and is a good start for getting basic FIM capabilities on Windows. For a long time, this capability was available only on Linux and macOS until a much later version when FIM was also available using osquery’s ntfs_journal_events table created on Windows. The evented tables capture the events on a pre-determined set of directories (or files) and thus osquery agent captures the changes to the files being monitored. Osquery achieves FIM through the evented tables. Thereby, having a FIM solution is not only important from the standpoint of a compliance requirement, it also is an essential toolkit for security monitoring.
FIM solutions use different methods, such as comparing file attributes (e.g., file size, timestamps, hashes) to detect changes, monitoring file access and modification events, or using machine learning to detect anomalous behaviour. configuration as well as content files) and can trigger alerts based on rules around the access. FIM solutions are also used to monitor activities on sensitive files (e.g.
#Timeline using table tool software
The aim of FIM is to verify the integrity of application software files to determine if they have been tampered with or if a fraud has occurred by comparing them with a baseline. FIM is an important security control needed for almost all kinds of compliance requirements, like PCI DSS, HIPAA, GDPR and ISO. File Integrity Monitoring (FIM) is a security control that helps organizations ensure the integrity of their files and systems by monitoring changes to files and directories.
