Shields Up for Cyber Safety
In this lesson, students learn the concept of the Dual-Shield Defense for cybersecurity: The Outer Shield (Technical Perimeter Defenses): Automatic, structural blocks that prevent risks from ever reaching a user's account or device. This includes DNS (domain name system) filtering tools such as CIRA Canadian Shield, ad blockers, multi-factor authentication (MFA), and device-level Stolen Device or Theft Protection. The Inner Shield (Human Cognitive Verification): Active mental habits that allow users to spot, analyze, and neutralize scams that get past the outer shield. This includes detecting psychological triggers (Urgency, Fear, Authority, Secrecy), applying the "Take Five, Tell Two" rule, and using robust offline verification protocols.
