File server
This tutorial is your guide to understanding and implementing effective file server monitoring and securing techniques using EventLog Analyzer.
Before diving into audit reports and activating detection rules, it's crucial to establish a solid monitoring foundation for your file server. This involves configuring logging settings and integrating them seamlessly with the EventLog Analyzer console.
Throughout this tutorial, we'll focus on practical strategies for monitoring your file server, helping you detect anomalies and track file access patterns to maintain data integrity.
Securing Windows and Linux file servers: A log-based approach with EventLog Analyzer
EventLog Analyzer covers the below file server auditing use cases with its security auditing reports. These reports are predefined and can be scheduled to be generated at specific times and distributed over email. EventLog Analyzer supports file servers on both Windows and Linux platforms.
| Use Case | Description | Why implement? | Available Reports |
|---|---|---|---|
| Windows File Monitoring | Track user interactions, file modifications, and access attempts, both in real time and retrospectively. Detect suspicious behavior, prevent unauthorized access, and maintain the integrity of your critical data assets. | Enhance security, facilitate auditing, and ensure compliance by keeping tabs on file access, modification, deletion, and creation. |
|
| Linux File Monitoring | Use various system-level mechanisms and tools to observe and analyze changes occurring within the Linux file system. | Implement file monitoring on a Linux system to ensure security, compliance, integrity, incident response, proactive maintenance, and auditing. |
