How to confirm if the IP Reputation App for Splunk Enterprise is connecting to the Honeypot to retrieve bad IPs?

I have set up the app and I think it is working, but how do I confirm that a list of Bad IP is being created? I presume there is a search I can use for this.

Thanks

Hi Andy,

the app is working different then then threat list download's in ES or some other threat intel apps on Splunkbase.

The lookup to IP's is done in realtime via DNS query. so there is no threat list download. It's using the http:BL api: https://www.projecthoneypot.org/httpbl_api.php

To test:

* | head 1 | eval clientip = 89.234.157.254 | lookup threatscore clientip | table clientip, threatscore

In words:
Take any event, add to this event a field called clientip with eval. I took an ip from the project honeypot website that showed bad activity. then doing the scripted lookup. the scripted lookup gives back a new field called threatscore. The ip associated with bad activity should have a threatscore between 1-100 - not 0!

Hi Andy,

sorry syntax error. you need to to make " " around the IP Address in the eval command.

 * | head 1 | eval clientip = "89.234.157.254" | lookup threatscore clientip | table clientip, threatscore
