It’s been quite a long time since my last post here. I’m now taking the opportunity to share one article I wrote about Splunk , which might be of some help to the community.
Since I’ve been using that technology for a while, I’ve decided to leverage such knowledge in order to renew one GIAC certification I got in the past (GCIA). Basically, the paper’s content is about installing Splunk Enterprise (freely available version) on a Linux machine, getting network data processed based on tshark’s output, and finally extracting some interesting stats and charts out of it.
It was also a fun way to introduce Splunk’s data mining features, which might hopefully enable users to develop new ideas based on the approach presented in there. As expected, there should be many other ways to accomplish the same results while processing IP packet headers, whether it’s using Splunk or not, so I would really appreciate receiving feedback about other approaches used out there.
