Once waited for and processed, subsequent events can be queued with FindNextChangeNotification.The handle returned by FindFirstChangeNotification can be used with the standard Windows object waiting routines, like WaitForSingleObject and WaitForMultipleObjects.FindFirstChangeNotification can be used to place a set of notification filters on a particular directory’s entries (and those of all subdirectories, if requested).The Windows API provides a collection of (mostly) filesystem-agnostic functions for polling for events on a registered directory: We’ll cover the technical details of each of these approaches, as well as their advantages and disadvantages (both general and pertaining to osquery) below. Filesystem filter drivers and minifilters.


Many malicious activities are reliably sentineled or forecast by well-known and easy to identify patterns of filesystem activity: rewriting of system libraries, dropping of payloads into fixed locations, and (attempted) removal of defensive programs all indicate potential compromise.Read the schema documentation here!įile monitoring for fleet security and management purposesįile event monitoring and auditing are vital primitives for endpoint security and management: You can use this table today to performantly monitor changes to specific files, directories, and entire patterns on your Windows endpoints. TL DR: Trail of Bits has developed ntfs_journal_events, a new event-based osquery table for Windows that enables real-time file change monitoring.
