Tri-Cities Security Group

We're a group of security professionals, located in and around the Tri-Cities area, in Southeastern Washington State. DC509 is associated loosely with Defcon, home of a well-known security conference. Multiple groups associated with Defcon are located world wide.

Our Meeting Schedule

We meet once a month, on the third Saturday. Our inaugural meeting was in January, 2008.

Topics reflect the group's interests, and vary between Community Outreach meetings, and technical topics for the local group.
