The 2007 International Capture The Flag in UCSB
The UCSB International Capture The Flag (also known as the iCTF) is a distributed, wide-area security exercise, whose goal is to test the security skills of the participants from both the attack and defense viewpoints.
The Capture The Flag contest is a multi-site, multi-team hacking contest in which a number of teams compete independently against each other.
Each team is given a virtualized network installation (for example, a Linux host and/or a Windows host). The hosts provide a number of services. The services have a number of undisclosed vulnerabilities, which have been included in the servers' software by the contest organizers.
The goal of each team is to maintain the set of services available and uncompromised throughout the contest phase. Each team can (and should) attempt to compromise other teams' services. Since all the teams receive an identical copy of the virtual network, the task of each team is to find vulnerabilities in their copy of the hosts and possibly fix the vulnerabilities without disrupting the services. At the same time, the teams have to leverage their knowledge about the vulnerabilities they found to compromise the servers run by other teams. Compromising a service will allow a team to bypass the service's security mechanisms and to "capture the flag" associated with the service.
During the contest a scoring system keeps track, for each team, of which services are available, and which services have been compromised.
The 2007 iCTF is scheduled Friday, December 7, 2007, from 8am to 5pm, PST.
