Open Source Host-based Intrusion Detection System performing log analysis, file integrity checking, rootkit detection, and active response.
OSSEC is an Open Source Host-based Intrusion Detection System (HIDS) that provides comprehensive security monitoring for computer systems. It performs log analysis, file integrity checking, policy monitoring, rootkit detection, real-time alerting, and active response to security threats. The platform combines multiple security functions into a unified solution for detecting and responding to intrusions.
System administrators, security professionals, and organizations needing open-source intrusion detection and security monitoring capabilities for their infrastructure.
OSSEC offers a complete, integrated security monitoring platform that's both powerful and accessible as open-source software, eliminating the need for multiple disparate security tools while providing real-time threat detection and automated response capabilities.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Integrates HIDS, log analysis, and SIM/SIEM into a single platform, eliminating the need for multiple disparate tools as highlighted in the project description.
Fully open-source with no licensing costs, making it accessible for organizations of all sizes, as emphasized in its value proposition.
Offers active response mechanisms to automatically counteract threats, demonstrated in the SSH attack detection screenshot from the README.
Effectively detects unauthorized file changes with visual examples provided in the FIM screenshot, ensuring critical system integrity.
Requires significant expertise to configure rules and policies, with documentation hosted externally, which can lead to a fragmented learning experience.
File integrity checking and log analysis can impose high CPU and memory overhead, especially on large-scale deployments with frequent scans.
Lacks a modern web-based GUI, relying on command-line interfaces and basic screenshots, which may hinder real-time monitoring for less technical users.
