Hello
At the beginning I have a lot of problem with information chaos with the differences between Snort 2 and Snort 3. There are plenty books and info about Snort 2, but not many about Snort 3. For example Snort 2 Manual (y. 2020) is 270 page book and but Snort 3 Manual (y. 2024) is 116 page book and there is very little info.
I can only guess what is the latest approach in using Snort 3, for example thanks to the latest videotutorials on YT. I really miss the forum on Snort to not making spam for example here
To the point, there are up-to-date such logger modules in Snort (alerts and packet logger).
At this point, I used alert_fast, alert_full and alert_json, because I found tutorial which recomended alert_json because there is possibility to integrate this with Splunk (I found myself alert_fast and alert_full too). OK. I did that.
But, what with unified2? The old materials tell a lot about it. But now, nothing.
From Snort 2 manual:
Unified2 can work in one of threemodes, packet logging (log_unified), alert logging (alert_unified2), or true unified logging(unified2).
In Snort 3 Manual is mentioned only about unified2.
Is unified2 mode is used by anyone? Or this is only history? Is Snort 3 at all is able to use log_unified, alert_unified2 or only unified2(packet and alert)?
