Introducing EvidenceForge: Synthetic security logs that don’t look (as) fake

Source Cisco Talos

Description

EvidenceForge generates high-quality, realistic, and consistent datasets across multiple log formats, enabling teams to effectively train personnel and validate detection models without the need for complex manual simulations.

Impact

EvidenceForge itself is not a security vulnerability or threat. Instead, it provides security teams with realistic synthetic datasets that improve training, detection tuning, and analytic model validation. This reduces reliance on anonymized, stale, or incomplete public datasets and costly manual simulations. There is no indication of exploitation or risk introduced by EvidenceForge; rather, it enhances defensive capabilities by enabling more effective preparation and testing.

Defensive guidance

No remediation or mitigation is required as EvidenceForge is not a vulnerability or threat. It is a beneficial tool designed to aid security teams in generating realistic training and testing data. Organizations can adopt EvidenceForge to improve their security operations and detection capabilities.

Summary

EvidenceForge is a synthetic log generation tool that creates realistic, multi-format security datasets by using a single canonical event model with shared context objects, ensuring causal and temporal consistency across logs such as Windows Security Events, Sysmon, Linux syslog, Zeek, Snort, and others. Unlike traditional synthetic generators that emit independent events per format, EvidenceForge produces correlated logs that tell a coherent story, including realistic background noise and red herrings. It supports sensor placement modeling to reflect realistic network visibility and uses AI-assisted scenario authoring to collaboratively develop attack narratives. The tool outputs labeled datasets with ground truth documentation and analyst briefings, facilitating SOC training, detection validation, and ML model training. EvidenceForge is open-source and available on GitHub.
