SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyze system and security logs (auth.log, syslog, Windows EVTX, Apache/Nginx, JSON logs). Detect brute force, lateral movement, privilege escalation, and anomalous activity.

Core Features & Use Cases

  • Real-time log parsing for Linux, Windows, and web servers
  • Correlation across log sources to reveal attack chains
  • Automated detection of brute-force attempts, privilege escalation, and lateral movement

Quick Start

Run a log analysis on the target log file or directory to identify anomalies and brute-force patterns.

FAQPage Schema
How do I detect brute-force attacks in Linux auth logs and syslog?

To detect brute-force attacks in Linux auth logs and syslog, you can parse the files to identify anomalous activity and correlate events across sources. This process reveals attack chains and generates a structured security report.

Can I analyze Windows EVTX files to identify privilege escalation and lateral movement?

Yes, you can analyze Windows EVTX files to identify privilege escalation and lateral movement. The analysis applies predefined parsing rules to the logs, correlating events across sources to detect these specific anomalous activities.

What is the best way to parse web server logs for security anomalies?

The best way to parse web server logs for security anomalies is to apply predefined parsing rules that support multiple log formats. This correlates events across log sources to automatically detect anomalous activity and brute-force patterns.

Does log analysis work with multiple log formats simultaneously?

Yes, log analysis works with multiple log formats simultaneously, including Linux auth logs, Windows EVTX, syslog, and web server logs. It correlates events across these diverse sources to reveal comprehensive attack chains.

How do I get a structured report after analyzing system logs?

To get a structured report after analyzing system logs, run an analysis on your target log file or directory. The process parses the logs, detects anomalies like brute-force attempts, and automatically generates the structured report.
