File access monitoring for Windows File Server involves capturing and analyzing native Windows audit events, translating those raw events into readable audit trails, and surfacing alerts and reports that support security investigations and compliance.
An effective solution for these requirements is one that reliably collects Security event logs at scale, associates events with users and originating machines, identifies atypical access patterns, and produces audit-ready reports and timelines that can be exported.

Frequently Asked Questions (FAQs)
For detailed file access and permission auditing, enable SACLs and the primary event IDs such as 4663 (object access), 4670 (permissions), and 5140 (share access), depending on your Windows version and auditing requirements. Vendor docs and product pages linked above include guidance on recommended SACL settings.
It depends. Some vendor products support both agentless collection of Windows event logs and WMI and installation of lightweight agents. Other vendor products require the installation of an agent to provide more reliable data or to collect file integrity events and offline stored events. Review the vendor’s architecture for the supported collection modes. For example, Both Netwrix Products and Quest Software can provide an agentless collection mode in many cases.
If the workload is heavily focused on file access visibility, compliance reporting, and fast forensic sequencing, use a purpose-built solution. If you require cross-source correlation, custom analytics, and long-term archival across multiple types of telemetry, then use a SIEM solution. Many organizations implement both types of solutions, using the file auditor for fast investigations, while using the SIEM solution for correlation and long-term analytics.
