Welcome to the Open SIEM project.

Event Log Library

The log library is meant to be a source for information on log events from all operating systems and applications.

Eventually this will contain a massive library of event logs across multiple operating systems and hundreds of applications. Right now this is a work in progress.

Community Forums

A forum for SIEM professionals and anyone who has to work with logs.

to data breaches is a bit like reading random pages of War and Peace-it is hard to
understand the story when the data is indiscriminate in nature and lacks context."
