OpenFPC – An update: v0.2.97 available (woohoo!)

with 4 comments

It’s been a couple of months since I first posted about the OpenFPC project, so I thought it’s time that I provided a little update.

Firstly, I need to throw some karma over to Edward Fjellskål (http://gamelinux.org), so… Edward++.

Edward and I have merged the OpenFPC and FPCGUI projects, it makes way more sense to combine our efforts as our goals are similar while our approaches have been from different angles. We both see a need to unify all of the home-brew full-packet-capture/network forensics tools we see out there in the wild.

OpenFPC now has a new home, http://www.openfpc.org.  So, if you’re looking for a distributed wrapper for your daemonlogger instances, or if you’re still trying to get tcpdump to log in a ringbuffer and share access over multiple analysts, devices, and tools, head on over to www.openfpc.org to read all about it. Here are a couple of quick links for those who want to jump right in:

I’m looking for people to help test and provide feedback now so I can fix problems and tweak things ahead of a full release.

Good luck, and please let me know your feedback.

TweetYard – Sourcefire and Snort alerts to Twitter

with 4 comments

Update: – You can download tweetyard here.

There has been some of discussion of late on the snort-* lists of late regarding Unified alerting vs direct DB access.

I stopped storing events in a DB years back when I stopped using ACID (and yes that was back-in-the-day before BASE came into being). My personal Snort requirements are pretty simple and fast output has always worked well for me linked with a load of swatch-foo and custom perl scripts. After hanging my head in shame for not converting to unified yet (cobblers children clearly have no shoes over here) I thought it would be wise to put some effort in.

I used to receive all of my Snort IDS events via email, but email is *so* web 1.0. So I thought I would hook into Twitter for real-time alerting 🙂

So far, so good, and it only took about an hour to build. Kudos to Jason Brvenik for his snort-unified.pm and sample barnyard replacement, it was a good base for what I wanted to hack together. Because I put this together more than fun more than anything else, feel free to follow a censored Twitter feed of my IPS events (If you didn’t have enough to deal with already).  I have blanked the IPs of my protected systems in an attempt to raise the smarts-to-abuse bar up 0.2 inches above short skiddie tall.

I will upload the code when I get a spare couple of minutes, but as I will be attached to the Sourcefire booth @ Infosecurity London for the next three days it may take a while. Hooking it into Sourcefire’s Estreamer is also on the cards the next time I get some down-time.

If anyone is at the show, feel free to drop by the Sourcefire booth and say hi (and to bring me a Coffee at the same time).
