Defend, learn,
move up
Every event is scored the same way, so results compare across years. TCDC 1 is open to student teams. SMC is for the senior military colleges.
How the events connect- Live defense
Run a real business network for the whole event. Keep every service up while it is under attack.
- Business injects
Handle new tasks from a simulated company, from new user accounts to incident reports for leadership.
- Red team and debrief
An industry red team attacks. Afterward, each team gets a written debrief on what was found.
Built on the collegiate defense format
The National Collegiate Cyber Defense Competition (CCDC) has paired universities, industry and government for years. TCDC brings the same format to Texas, run on the Texas Cyber Range by TxCR.
Students who run and defend a company network for the whole event.
Industry practitioners who attack, log every compromise and debrief.
Officials who set the rules, grade injects and publish the scores.
