Open source siem tools are available for the public to modify and the best tools enjoy a community of loyal supporters. With ossim users get a powerful siem open source tool with the logging and monitoring elements of sem and the threat assessment automated responses and data synthesis of sim. A siem whether it is open source or commercial is virtually useless without the basic security controls necessary for security visibility. The open source version of alienvault s unified security management usm offering ossim is probably one of the more popular open source siem platforms.

This allows it professionals to modify and share the tools code much more freely offering important customizability and adaptability. As an organization grows open source siem software can become labor intensive. It experts across the globe share their knowledge and experience to tweak open source siem code meaning the tool itself is constantly evolving. Many open source siem solutions lack key siem capabilities such as reporting event correlation and remote management of log collectors.

An organization may save money on licensing costs but spend money on continual maintenance. Open source siem and free siem tools can seem like the solution. Ossim includes key siem components namely event collection processing and normalization and most importantly event correlation.
