Digital Privacy & Modern Security: What's New Here

Build the mental model

You already know passwords, 2FA, phishing, malware, social engineering, network security, encryption, password managers, backups, mobile security, the OWASP Top 10, secrets management, and incident response from Cybersecurity Basics. This course does not repeat any of it.

Digital Privacy & Modern Security picks up where those fundamentals leave off, focusing on what has changed in how people authenticate, browse, and get targeted online.

• Passkeys - a new authentication model replacing password-typing with public-key cryptography
• Public Wi-Fi & VPN risks - untrusted-connection dangers and what a VPN genuinely limits
• Browser security - extensions, tracking, sandboxing, and safe browsing habits
• Digital privacy - treated as its own discipline, separate from security
• Developer authentication & API security - for anyone building software
• AI & vibe-coding security - the security implications of AI-assisted coding

Think of this course as an upgrade path: it assumes your Cybersecurity Basics knowledge is solid and spends its time exclusively on what's genuinely new since you finished that course.

  AI & vibe-coding security

Connect it to a real scenario

In practice, the fastest way to get value from this course is to check your own starting point before diving in. If any of Cybersecurity Basics' topics feel shaky, that's worth a quick refresher there first.

The code example below models that self-check. It takes a small self-report of what you already know and returns, for each new chapter, whether it's genuinely new material and whether you're ready to start it now or should review a prerequisite first.

• Passkeys and Developer Authentication lean on solid password/2FA understanding
• AI & Vibe-Coding Security leans on solid phishing understanding
• Privacy, Browser Security, and Wi-Fi/VPN require nothing beyond the basics course as a whole

Try adjusting the input flags yourself and rerunning the function: change `knowsPhishingBasics` to `true` and notice how the "AI & Vibe-Coding Security" recommendation flips accordingly.

• This course never re-teaches Cybersecurity Basics topics
• Passkeys, privacy, browser security, and developer/AI security are the genuinely new additions
• A quick self-check of your prior knowledge before starting pays off

Try the working example

const courseChapters = [

  { name: "Public Wi-Fi & VPN Risks", requiresPrior: [] },

  { name: "Developer Authentication & API Security", requiresPrior: ["knowsPasswords2FA"] },

];

function newChaptersFor(learner) {
  return courseChapters.map(ch => {
    const ready = ch.requiresPrior.every(req => learner[req]);
    return {
      chapter: ch.name,
      isNewContent: true,
      readyToStartNow: ready,
      recommendation: ready ? "Start anytime" : "Review that topic in Cybersecurity Basics first"
    };
  });
}

const learner = { knowsPasswords2FA: true, knowsPhishingBasics: false, knowsEncryptionBasics: true };
console.log(JSON.stringify(newChaptersFor(learner), null, 2));
