Just a quick note today about threat sharing groups. 

I am talking to more and more companies and organizations that are putting together local, regional or vertical market threat sharing groups. These are often adhoc and usually driven by security practitioners, who are helping each other with cooperative defenses and sharing of new tactics and threat patterns (think TTPs (tactics, techniques & procedures)) or indicators of compromise (IOCs). Many times, these are informal email lists or RSS feeds that the technicians subscribe to and share what they are seeing in the trenches. 

A few folks have tried to commercialize them, but in most cases, these days, the sharing is simply free and open. 

If you get a chance to participate in one or more of these open source networks, you might want to check it out. Many of our clients are saying great things about the data they get via the networks and often they have helped contain incidents and breaches in a rapid fashion.

If you want to discuss your network, or if you have one that you’d like me to help promote, hit me up on Twitter (@lbhuston). If you are looking for one to join, check Twitter and I’ll share as folks allow, or I’ll make private connections as possible. 

As always, thanks for reading, and until next time, stay safe out there!
