The National Collegiate Cyber Defense Competition (NCCDC) is the championship event for the Collegiate Cyber Defense Competition system – the largest college-level cyber defense competition in the world. The event is held annually in the San Antonio area. The 5th National Collegiate Cyber Defense Competition is scheduled for April 16–18, 2010.
In an effort to help facilitate the development of a regular, national level cyber security exercise, the Center for Infrastructure Assurance and Security at the University of Texas at San Antonio (UTSA) hosted the first Collegiate Cyber Defense Competition for the Southwestern region in May 2005. On June 29, 2010, United States House legislature passed recognizing the National CCDC for promoting cyber security curriculum.
While similar to other cyber defense competitions in many aspects, the NCCDC, is unique in that it focuses on the operational aspect of managing and protecting an existing network infrastructure. While other exercises examine the abilities of a group of students to design, configure, and protect a network over the course of an entire semester, this competition is focused on the more operational task of assuming administrative and protective duties for an existing commercial network. Teams are assessed based on their ability to detect and respond to outside threats, maintain availability of existing services such as mail servers and web servers, respond to business requests such as the addition or removal of additional services, and balance security needs against business needs.
