DC615 Nashville joins a new educational initiative with TN Homeland Security!

DC615, the DEF CON group based out of Nashville, TN is excited to be a part of a new initiative between the Tennessee Department of Safety and Homeland Security, and local law enforcement! The new initiative builds a stronger connection between members of the Information Security community and federal and local law enforcement, with emphasis on educating on the risks of cyber security, as well as details for remediation efforts.

DC615 has been chosen as the group to help build this initiative. We are building a framework with the Tennessee Department of Safety and Homeland Security that can be shared and used by any DC group, and look forward to being able to share our knowledge through training events, speaking engagements, and whatever other capacity that we can be utilized to help educate and strengthen the security posture of schools, federal and local law enforcement. This is a great way for us to not only help give to our community, but to help educate others as well.

The project was announced at DEF CON 25, and has been in planning with Jayson Street, Brent White, and the Tennessee Department of Safety and Homeland Security since the projects inception around April, 2017. Events will be announced soon, and we will keep you updated on this project.

DEF CON Groups Update for 2018!

DEF CON Groups Ambassador Jayson Street has a vid for you, summing up the past year and giving you the scoop on some of our plans for 2018. We've got big things in the works and we're hoping you'll join us in making this the best DCG year ever!

How to Start a DEF CON Group

A local DEF CON group (DCG) is part of “a global community of hackers, thinkers, makers and others bent on being part of the elegant chaos they want to see in the world” (--The Dark Tangent)

DCG is a great way to meet, learn, and share with local hackers.

If there is not a local DCG within a reasonable commute from your area, you may want to start your own group.

Welcome from The Dark Tangent!

I am proud to unveil the launch of the new DEF CON Groups website,! will provide a centralized place to socialize, learn new skills, collaborate, and show off recent projects to DEF CON Groups around the world . It will include a directory to make it easier to find like-minded hackers in your area, as well as showcase featured DEF CON Groups, guest blogs, videos, tutorials, and more.

To help make this happen Jayson E. Street, the unofficial DEF CON ambassador for the last 15 years, will now take on an official role as the new DEF CON Groups coordinator. Jayson has been active in the DEF CON community for years, and he embodies a spirit of openness and energy  that I am looking for to take the DEF CON Groups to a new level.

Jayson has assembled a team to help make this happen. @ioCassie, @tottenkoph, @KentNabors, and @Sara_Kantor have all volunteered their time and responded ten-fold in their efforts to make this community happen. They have a lot of work ahead of them yet to even begin. With the community's help they're going build the road to benevolent world domination that was set in motion back at DEF CON 2001 by Speed Russr when he came up with the idea for the DCG.
