An organization may save money on licensing costs but spend money on continual maintenance.
Open source siem. Many open source siem solutions lack key siem capabilities such as reporting event correlation and remote management of log collectors. 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. This allows it professionals to modify and share the tools code much more freely offering important customizability and adaptability.
Open source siem tools are available for the public to modify and the best tools enjoy a community of loyal supporters. Open source siem tools literally open their cybersecurity design to the public. 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. 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. The open source version of alienvault s unified security management usm offering ossim is probably one of the more popular open source siem platforms. Open source siem and free siem tools can seem like the solution.
