Intrusion Detection and Prevention / Re: Suricata 4.1.2 does not block traffic

I can confirm that everything works after patching 4.1.2_1 version. Tested with eicar, urlhaus and a few policy rules.

There is a patch/fix that will be included in 19.1.2

I haven't tried it myself yet..

Hi! One more confirmation from my side. Blocking is not fully functional in Suricata 4.1.2.

Blocks do occur, but 2 out of 4 test downloads of eicar.com file won't be blocked. Same goes for the rules like abuse.ch (i tried *.co.cc rule in my testing).

I run OPNsense in a virtual enviroment, VMware ESXi, on a Qotom Intel i3 box with Intel chipset..

Something has gone wrong with this version? I can provide further details to try and find the culprit (debugs, logs?)

Greetings,
Tom

EDIT:
Just to add more details: OPNsense 19.1, Suricata 4.1.2_1
Allthough logs show me eicar is blocked, the file is succesfully downloaded
- attached screenshots

Reverting back to Suricata 4.0.5 is not an option for me at the moment, since i need to revert back to OPNsense 18.7 due to GeoIP dependencies..

EDIT2:
I managed to succesfully install GeoIP and Suricata 4.0.5 on OPNsense 19.1 and blocking is working once again. Tested with a few rules including abuse.ch and eicar.
To conclude - Suricata 4.1.2 NOT working properly on OPNsense 19.1

Some events are not being pushed to syslog from eve.json. Could not find out why, but found a solution to push everything from eve.json to elasticsearch (as i see, you are using it as well).

Install filebeat on opnsense host and change filebeat.yml to point to logstash using this guide:
https://extelligenceblog.it/2017/07/11/elastic-stack-suricata-idps-and-pfsense-firewall-part-1/


Configure logstash:
beats {
    type => "Suricata"
    port => 5044
    codec => json
  }
filter {
         if [type] =~ /^Suricata/ {
                mutate {
                  add_tag => ["Suricata"]
                  remove_tag => ["beats_input_codec_json_applied"]
                  replace => {"service" => "Suricata"}
                }
        }
}
output {
if [type] == "Suricata" {
    elasticsearch {
      hosts => ["http://localhost:9200"]
      index => "suricata-%{+YYYY.MM.dd}"
    }
  }
}

Hope it helps.
Cheers
