The Information Security Talent Search is a college security competition designed and ran by students, for students.
The first Information Security Talent Search was held in 2003, organized by the Security Practices and Research Student Association (SPARSA) at the Rochester Institute of Technology in Rochester, NY. Beginning as a small, in-house competition for SPARSA members and RIT students, ISTS has grown to include teams representing numerous colleges from the northeastern, mid-atlantic, and midwestern regions of the United States. Each subsequent year of competition has evolved ISTS slightly, changing everything from the competition rules and structure, to the hardware and software used by the competitors. To this day, ISTS remains a completely student-organized and student-run competition.
