Learners follow data across the internet (packets with IP addresses, routers choosing paths, and DNS turning names into addresses), use a simple shift cipher to understand encryption and what the padlock in a browser really means, and build a personal security toolkit: unique passphrases, a password manager with a trusted adult, two-step verification, updates and care on public Wi-Fi.
