Threat Detection Tools

Threat detection is the practice of identifying suspicious activity, vulnerabilities, and signs of compromise across computers, networks, and applications. It helps security teams find potential attacks early, investigate unusual behavior, and reduce the time between an intrusion and a response. Detection can use system and network logs, known indicators, behavioral analysis, or low-level operating system events. Some approaches focus on continuous monitoring, while others analyze collected data to uncover patterns that may otherwise go unnoticed.

Open source tools in this area include host monitors, log analysis systems, network sensors, honeypots, and rule-based or behavior-based detection engines. When choosing one, consider the systems it supports, data sources and integrations, deployment requirements, alert quality, maintenance activity, and license. These tools can be useful to security teams, system administrators, researchers, and organizations building their own monitoring workflows.
