MACCDC takes great pride in being one of the premier events of this type in the world.

The 2024 Mid-Atlantic Collegiate Cyber Defense Competition (MACCDC) is in its 19th year of providing a unique experience for college and university students to test their cybersecurity knowledge and skills in a competitive environment. In 2023, more than 200+ students competed for an opportunity to be one of eight teams to advance to the Regional Finals. The winner of the MACCDC represents the Mid-Atlantic region at the National CCDC, usually the third week in April.

“Such experiential education increases the knowledge and expertise of future professionals who may be in a position to contribute to the secure design and operation of critical information and its supporting infrastructure.”
from Exploring a National Cyber Security Exercise for Colleges and Universities, Lance J. Hoffman and Daniel Ragsdale, 2004

While similar to other cyber defense competitions in many aspects, MACCDC, as part of the National CCDC, is unique in that it focuses on the operational aspects of managing and protecting an existing network infrastructure. Teams are physically colocated in the same building. Each team is given physically identical computer configurations at the start of the competition. Throughout the competition, the teams have to ensure that the systems supply the specified services while under attack from a volunteer Red Team. In addition, the teams have to satisfy periodic “injects” that simulate business activities IT staff must deal with in the real world.

In spring 2006, five teams from Maryland, Virginia, and Pennsylvania competed in the 1st MACCDC. By today’s standards, the infrastructure was simple. Each team had a router, a firewall, and a small sampling of servers. Scoring was accomplished through a custom Perl script that checked network and service availability and integrity. In 2006, the teams defended a mere seven assets, including a router, a firewall, servers, and an IP surveillance camera, and there were only four Red Team members (“hackers”) attacking and disrupting the students’ infrastructure.
