an innovative video game and tool to teach computer and network security concepts  

CyberCIEGE enhances information assurance and cyber security education and training through the use of computer gaming techniques such as those employed in SimCity™. In the CyberCIEGE virtual world, users spend virtual money to operate and defend their networks, and can watch the consequences of their choices, while under attack.

Cyber Security Simulation
In its interactive environment, CyberCIEGE covers  significant aspects of computer and network security and defense. Players of this video game purchase and configure workstations, servers, operating systems, applications, and network devices. They make trade offs as they struggle to maintain a balance between budget, productivity, and security. In its longer scenarios, users advance through a series of stages and must protect increasingly valuable corporate assets against escalating attacks.

CyberCIEGE includes configurable firewalls, VPNs, link encryptors and access control mechanisms.  It includes identity management components such as biometric scanners and authentication servers.   Attack types include corrupt insiders, trap doors, Trojan horses, viruses, denial of service, and exploitation of weakly configured systems.   Attacker motives to compromise assets differ by asset and scenario, thereby supporting scenarios ranging from e-mail attachment awareness to cyber warfare.
