Synthetic RFC5424 Syslog Generator (SIEM Benchmark Dataset)

This dataset generator produces synthetic RFC 5424-compliant syslog events designed for benchmarking high-performance Security Information and Event Management (SIEM) systems. It simulates realistic enterprise telemetry including authentication logs, network flows, process activity, and lateral movement patterns.

Dataset Characteristics

Format

RFC 5424 syslog format
Structured data embedded in [SD] blocks
UTF-8 plain text logs

Example:

<34>1 2026-04-26T12:34:56.123Z host3.example.com sshd 4821 - [evt event_type="auth_fail" user="alice" src_ip="8.8.8.8" dst_ip="host1.example.com" action="login" status="fail"] auth_fail

Ethical Considerations

This dataset is synthetic and does not contain:

real user data
real IP addresses
production system logs

It is safe for benchmarking and research use.
