FolSec File Audit & Event Monitoring Whitepaper

File Auditing, Compliance, and Real-Time Event Monitoring

1. Introduction

In enterprise environments, being able to answer questions like “Who accessed which file, when, and what was done?” is critical not only for data security but also for regulatory compliance.

Folsec is an advanced monitoring and auditing solution that captures and analyzes all critical activities on file servers, based on NTFS permissions. It monitors user actions, file operations, process-level activities, and suspicious behaviors, and generates alerts when necessary to keep administrators informed.

2. Compliance Alignment

Folsec supports the following standards and regulations by providing extensive event logging and reporting capabilities:

KVKK (Turkish Personal Data Protection Law)

Tracks access to personal data, logs unauthorized access attempts, and preserves audit trails.

PCI DSS (Payment Card Industry Data Security Standard)

Monitors sensitive file access, audits permission changes, and supports secure data retention.

ISO/IEC 27001

Enables incident management, audit trail generation, and risk-based activity monitoring.

3. Event Types

3.1 File Events

Event Type Description

Read File was opened or read

Write / Modify File content was changed

Delete File was deleted

Create New file was created

Move / Rename File was moved or renamed

Extension Change File extension was modified

3.2 User Events

3.3 Process Events

Event Type Description

Scripted Access Access through scripts or automation tools (e.g., PowerShell, .bat)

Explorer Access Access via Windows GUI (explorer.exe)

Unknown Process Access by unidentified or suspicious process

System Process Access initiated by system-level processes (e.g., dllhost.exe)

4. Alerts and Anomaly Detection

Folsec includes a built-in anomaly engine that analyzes events and triggers alerts for suspicious behavior patterns.

Alert Type Description

Mass Delete Detection Large number of file deletions in a short time

Ransomware Activity Pattern Read + write + delete operations in rapid succession

Protected Folder Violation Abnormal activity in high-value folders

Sudden Access Spike User performing an unusually high number of operations suddenly

Note: All thresholds and patterns are customizable by the Folsec administrator.

6. Conclusion

Folsec enhances file security by combining permission management with behavioral auditing and anomaly detection. Its File Audit framework enables IT administrators to not only track what happened—but also understand why it happened.
