Foundations of Digital Defense
Before you touch a single tool, you need a map of the battlefield and a working theory of how attacks actually happen. This track builds the mental models that everything else rests on: who is trying to hurt you and why, how the machinery of authentication really works, how humans get manipulated, and how to shrink the trail you leave behind. No jargon for its own sake, no fear-mongering — just the load-bearing fundamentals, taught with real incidents and real numbers.
What you'll be able to do
- ▸ You'll be able to explain who attacks, why, and how the cybercrime economy funds itself.
- ▸ You'll be able to reason about password strength in terms of entropy and real cracking speeds.
- ▸ You'll be able to set up phishing-resistant authentication — passkeys and hardware keys — and know why they beat SMS.
- ▸ You'll be able to spot phishing, vishing, and business-email-compromise attempts before you click.
- ▸ You'll be able to harden a browser, understand what a VPN does and doesn't do, and shrink your data trail.
- ▸ You'll be able to protect your devices with patching, the 3-2-1 backup rule, and full-disk encryption.
