To gain better visibility into real-time web attacks, SafeLine supports forwarding detailed logs via Syslog. This allows you to integrate SafeLine with third-party monitoring platforms like SIEM or log aggregators.
🔧 How to Configure Syslog in SafeLine
1. Enable Syslog Forwarding
Navigate to the System page in the SafeLine dashboard. Under Syslog Settings, input the required server address and port. SafeLine uses UDP protocol and follows the RFC-5424 standard for log formatting.
Note: Make sure your firewall allows UDP traffic to the specified Syslog server.
2. Verify Syslog Connectivity
Once configured, click the Test button. If the Syslog server receives a message like the following, your setup is working correctly:
<30>1 2024-03-20T20:02:38+08:00 55ae65e87e75 /matio/mario 1 safeline_event - Connectivity test requested.
đź“ť SafeLine Syslog Log Format
SafeLine outputs logs in structured JSON format, making them easy to parse and analyze. Each log entry contains detailed context about HTTP requests, including attack events, request metadata, and enforcement actions.
Here’s an example of a typical Syslog message:
