I’ve never done this before- finding what might be a bug(?) or just being nitpicky, but regardless I’m curious how to go forward with this:
When installing Snort on pfsense (some time ago snort and suricata ditched barnyard2 in pfsense and use Unified2 now) and checking “send logs to syslog…”
It does as it says, and I have a transforms.conf in the SIEM to source type it appropriately to have a technology add-on’s regex made for Unified2 format to do field extraction.
Example of output I am getting:
Example of output the Unified2 TA is expecting:
Note my snort output does not have interface information, the Unified2 example does. From memory before the Snort and Suricata drop of barnyard2 to Unified2, it used to have interface.
I can fix the regex but to me it seems snort’s implementation of Unified2 is not completely accurate.
How would one go about “reporting” this appropriately, tastefully and with the right information/logs/terminology?
