The list of open source projects included in OSSIM includes: FProbe, Munin, Nagios, NFSen/NFDump, OpenVAS, OSSEC, PRADS, Snort, Suricata and TCPTrack. OSSIM combines native log storage and correlation capabilities with numerous open source projects in order to build a complete SIEM. OSSIM includes key SIEM components, namely event collection, processing and normalization, and most importantly - event correlation. The open source version of AlienVault’s Unified Security Management (USM) offering, OSSIM is probably one of the more popular open source SIEM platforms. We will follow up this article with a similar analysis of proprietary tools. As always, though, there are some good contenders, and in this article, we take a look at six of these platforms. Existing solutions either lack core SIEM capabilities, such as event correlation and reporting or require combining with other tools.
There is no all-in-one perfect open source SIEM system. That’s why Logz.io Cloud SIEM exists, our proprietary endeavor to amalgamate open source options to create a defense-prioritized security solution for observability, largely based off the ELK Stack (more on that below). These solutions can become rather expensive, especially in the long run and in larger organizations, and so more and more companies are on the search for an open source SIEM platform.īut is there an open source platform that includes all the basic SIEM ingredients?
There are proprietary platforms that do offer an all-in-one SIEM solution, such as LogRhythm, QRadar, and ArcSight. One of the conclusions reached in that article was that SIEM is not actually a single tool in itself, but is instead comprised of multiple monitoring and analysis components.
In a previous post, we explained what a SIEM system actually is - why organizations require it to start with, the components it is comprised of, and how it helps mitigate attacks. Helping to protect IT environments from cyber attacks and comply with tightening compliance standards, SIEM systems are becoming the cornerstone for security paradigms implemented by a growing number of organizations.
