I wanted to query the community to see what novel or interesting data sources you have used along with the SIEM? For example, data sources like weather, record/album sales, employee degrees, HAVC system data, badge system data, etc. The goal of this discussion will be to determine novel and interesting data sources that each of us can consider for use in the SIEM. Ideally, this would allow for new correlations and lead to further value extraction from the platform.
I am looking forward to this discussion.
P.S. For the data sources that you mention, if they are available publicly, please link to the source.
