Security Onion is a security information and event management platform and network security monitoring suite. It functions as an intrusion detection system and a network traffic analysis tool designed to identify malicious activity and network intrusions through signature-based detection and host-based monitoring. The platform integrates a security case management system to organize investigations by tracking detections and grouping related security events. It provides capabilities for full packet capture, network metadata extraction, and the collection and indexing of security logs from dive
Substation is a toolkit for routing, normalizing, and enriching security event and audit logs.
DetectionLab is a reproducible Windows Active Directory security lab designed for testing detection capabilities. It uses an automation framework based on Vagrant and Packer to provision virtualized networks across multiple hypervisors and cloud platforms. The project utilizes Ansible for the declarative installation and configuration of domain services and endpoint security tools. It incorporates a browser-based remote access interface via Apache Guacamole to manage laboratory hosts without requiring standalone remote desktop clients. The environment includes a telemetry pipeline that aggre
CrowdSec is a collaborative, distributed security engine designed for threat detection and infrastructure protection. It functions as an intrusion detection system that parses logs and network traffic to identify malicious patterns, utilizing a bucket-based threshold detection model to aggregate events and trigger alerts. The platform is built on a modular architecture that includes a centralized local API server for managing security signals and a relational database for persistent storage of remediation decisions. What distinguishes the project is its decoupled enforcement model, which offl
HELK is a containerized security information and event management environment and threat hunting platform. It provides a security-focused deployment of the ELK stack, combining Elasticsearch, Logstash, and Kibana into a specialized platform for investigating logs and discovering hidden patterns in network and system security data. The project functions as a security data science suite, integrating interactive computational notebooks and distributed processing tools to run machine learning and graph analytics on security logs. This allows for the identification of hidden attack patterns and an

Varna: Quick & Cheap AWS CloudTrail Monitoring with Event Query Language (EQL)
Opensnitch is a host-based application firewall for Linux that monitors and intercepts outbound network connections in real time. By hooking into kernel-level interfaces, it tracks system-wide network activity and maps connection attempts to specific local processes, allowing users to explicitly permit or deny traffic on a per-application basis. The project distinguishes itself through its ability to manage security policies across multiple distributed nodes from a single, unified dashboard. This centralized management is secured via encrypted socket communication, enabling consistent rule en
capa is a static analysis tool that scans executable files to identify what a program can do, detecting capabilities such as API calls, byte sequences, and structural patterns without executing the code. It supports multiple file formats including PE, ELF, .NET, and shellcode, and can also process runtime behavior traces from sandbox reports generated by CAPE, DRAKVUF, or VMRay. The tool integrates directly with reverse engineering environments through plugins for IDA Pro and Ghidra, allowing analysts to view capability matches and author detection rules within their disassembler of choice.

IntelOwl is a threat intelligence platform and security orchestration engine designed to aggregate, analyze, and enrich security observables. It functions as a security incident investigation tool and a threat intelligence aggregator, collecting data on files, domains, and IP addresses from diverse internal and external sources. The system differentiates itself through playbook-based workflow automation, allowing users to define reusable sequences of analysis tasks that trigger subsequent jobs based on prior outputs. It unifies disparate security data into a common schema and utilizes protoco
