DEF CON Hacking Conference


Q: What are DEF CON Groups?

A: The DEF CON Groups were spawned from the annual DEF CON security conference in Las Vegas. The DEF CON Groups (DCGs or DC-Groups) are a gathering point for folks interested in the alternate applications of modern technology, referred to properly as 'hacking'. DCGs are not intended to compete with any other computer groups, such as 2600, but rather to provide yet another gathering place for the discussion of technology and security topics. DCG meetings are open to anyone, regardless of their skill, age, job, gender, etc. DCGs are designed to help you learn new things, meet new people, mentor others in areas you may be strong in, and provide some cohesion within the hacker culture and members.

DOs and DONTs of DCG Logos

The first goal of a DCG logo is to have an image that represents your group. It can be an image only, an image with text, or just stylized text. Let your imagination run wild. Logos must not be NSFW, illegal, or offensive.

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.

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.
