Open source siem.

The open source version of alienvault s unified security management usm offering ossim is probably one of the more popular open source siem platforms. Many open source siem solutions lack key siem capabilities such as reporting event correlation and remote management of log collectors. Open source siem tools literally open their cybersecurity design to the public. This allows it professionals to modify and share the tools code much more freely offering important customizability and adaptability.

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. A siem whether it is open source or commercial is virtually useless without the basic security controls necessary for security visibility. That said the tool has potential drawbacks.

As an organization grows open source siem software can become labor intensive. Launched by security engineers because of the lack of available open source products alienvault ossim was created specifically to address the reality many security professionals face. It professionals have noted the difficult setup process and the intensive upfront labor required to customize it.
