The snort integration is just following a snort socket; the same effect can be had by continuous integration of eve.json (trivial to process since, you know, its in json format...) and just processing inside of pigrelay. Handoff between pigrelay and ryu is even possible using partial extraction from eve alerts. Ya Unfortunately, I have no test environment to tinker with pigrelay and ryu, so t his is really about the only guidance I can offer. Someone else may have modified pigrelay, or have some insight into how it can be done. Doesn't look like it should be too difficult however, assuming you can hax python.</div><div dir="ltr"><div><br></div><div>Erik</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Dec 4, 2019 at 11:31 PM Priyatham Ganta <<a href="mailto:gantapritham4@gmail.com" target="_blank">gantapritham4@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Erik,<div><br></div><div>Can you give more details on this parser and any url on how to use it.</div><div><br></div><div>Thanks</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 3 Dec 2019 at 04:08, erik clark <<a href="mailto:philosnef@gmail.com" target="_blank">philosnef@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Phone message, sorry for spam.

No, there is a not way to do this with Suricata. Post-processing tools<br>
like Logstash could likeley be configured to make the transformation though.<br>
<br>
Eve is a generic format with mostly generic event parameters at the top<br>
level. Anything event_type specific is placed under the object for that<br>
event_type.<br>

Hi,<br>
<br>
I want to integrate Suricata with the Ryu controller and I checked that<br>
there is no built-in library for Suricata in the Ryu controller.<br>
<br>
I was thinking if I can convert Suricata messages to snort messages and use<br>
the same library or I want to know if there is any other way I can<br>
integrate Suricata with the Ryu controller to parse the alerts generated by<br>
Suricata.<br>
<br>
Thanks<br>
