Build and map networks, configure routers, switches, and firewalls, and learn to read what's actually happening on the wire.
Learn how locks work and why some fail. Members practice on their own practice locks, never locks in use, and see how physical and digital security connect.
Scope, consent, responsible disclosure, and privacy. Students learn why doing security work the right way matters, and agree to our acceptable-use guidelines before starting labs.
Members lead cyber-safety sessions for parents, seniors, and local organizations, teach their peers, and present research talks.
Local practitioners share how they work in security operations, forensics, engineering, and policy. We get out to events too: members attended DEF CON 2026.



We meet every other Sunday, all year round. Topics change based on what members want to dig into. Here's a sample.
Some members also compete as a team in capture-the-flag (CTF) competitions, solving security puzzles against the clock.
The team is optional and open to every member, whatever your experience. New to the club? Apply first, then tell us at a Sunday meeting that you want to compete.
No experience needed. We meet every other Sunday in Rancho Santa Margarita. Parents: here's what to know.
