Modern Cybersecurity: Zero Trust, Privacy & AI Security Course

Modern Cybersecurity is a premium, ~5.7-hour cybersecurity course for engineers and security practitioners — a deep, up-to-date guide to Zero Trust, passkeys, privacy engineering, threat detection, AI/LLM security, and software supply-chain defense. It's the mental model the engineers at Google, Microsoft, Apple, and Cloudflare actually use to build the controls that protect billions of users.

In September 2022, an 18-year-old logged into Uber's network with a password he bought for less than the price of a sandwich. Multi-factor authentication — the gold standard for fifteen years — lost to a single WhatsApp message. No zero-day. No nation-state. A teenager and a tired contractor.

That breach is where this course begins, because it raises the question every security architect now wrestles with: if perfect MFA still loses to a phone call, what does good security actually look like?

This isn't certification prep, and it isn't beginner theory. It's how the world's most-attacked companies defend in practice — explained one layer deeper than the marketing decks, through the real breaches that forced each defense into existence.

Who this cybersecurity course is for

This series is built for software engineers, security engineers, and practitioners who already understand what HTTPS does and what MFA means, and want the senior-level architecture knowledge that turns headlines into understanding.

By the end, you'll be the person on your team who can read a fresh breach disclosure and immediately spot what the defenders missed.

This course is right for you if you:

• Build, operate, or defend production systems and want to reason about security like an architect
• Keep reading about Scattered Spider, Volt Typhoon, prompt injection, or the XZ backdoor and want to truly understand them
• Want concrete, do-it-Monday-morning actions — not abstract frameworks

It's not the right fit (yet) if you need an absolute-beginner introduction or a certification cram. We assume the fundamentals and go straight to depth.

What you'll learn

Three tightly connected videos, each opening with a real named incident, extracting the architecture lesson, and ending with exactly what to do about it.

Part 1 — Identity at Scale: Zero Trust & Passkeys (≈96 min)

The front door: who gets in, and why every other defense sits on top of identity.

• What Zero Trust actually means as an architecture, not a slogan (NIST 800-207, the CISA pillars, and why it really means continuous, evidence-based trust)
• Google BeyondCorp — the first production Zero Trust, plus ALTS, Binary Authorization, and gVisor
• Microsoft Entra & the Secure Future Initiative — the breach so severe Microsoft publicly reorganized, and the Conditional Access model behind the response
• Cloudflare One — the exact cryptographic reason FIDO2 hardware keys beat the phishing campaign that broke 130 other companies
• Passkeys and WebAuthn, explained properly — origin binding, synced vs. device-bound, and the real end of password theft
• The Okta breaches, Scattered Spider, and the Snowflake wave — how modern attackers skip the cryptography and simply call the help desk
• Federal phishing-resistant MFA mandates, WebAuthn Level 3, OAuth 2.1, and the future of identity in the AI-agent era

Part 2 — Defending Billions: Privacy Engineering & Threat Detection (≈122 min)

What happens when the attacker is already inside — and how to protect data you can't even see.

• Apple Private Cloud Compute — how a server can prove it never read your AI prompts, and why Apple paid up to $1M to anyone who could prove them wrong
• Differential privacy and federated learning — using data without ever seeing it
• End-to-end encryption — the Signal Protocol, Advanced Data Protection, and the politics of the backdoor
• Threat intelligence — how Microsoft names and tracks 300+ state-backed hacking groups
• Volt Typhoon and Salt Typhoon — the new era of pre-positioning inside critical infrastructure
• ITDR, the modern SOC, detection-as-code, and the security data lake
• The CrowdStrike outage — the day one update took down 8.5 million machines, and what defense really costs

Part 3 — The New Frontier: AI Security & Software Supply Chain (≈124 min)

The two surfaces where attackers and defenders are still writing the rules — live, in production.

• EchoLeak — the first zero-click prompt injection against a production AI agent: one email, zero clicks, your entire SharePoint
• The OWASP Top 10 for LLM Applications (2025) and why prompt injection is the new SQL injection
• How the major AI labs actually defend their models — safety frameworks, red teams, and MITRE ATLAS
• Agentic AI security — the attack surface that doubled once assistants started to act
• Model theft and distillation
• Software supply chain security — SolarWinds, Log4Shell, and the full story of the XZ backdoor, the near-miss that came within days of compromising nearly every server on Earth
• The real defenses: SLSA, Sigstore, SBOMs, and reproducible builds

Why this cybersecurity course is different

Built on real incidents, not abstractions. Every concept is anchored to a named breach, a real CVE, and the specific control that would have stopped it.

Current and relevant. This is a definitive snapshot of where security stands today — the regulations in force, the products shipping, and the campaigns active in the wild right now.

Architecture-deep, with primary sources. Citations to NIST 800-207, the BeyondCorp papers, the Cyber Safety Review Board reports, OWASP, and MITRE — so you can keep learning after the video ends.

Action over trivia. Every part ends with a concrete order of operations you can apply Monday morning, whether you defend a Fortune 500 or a one-person SaaS.

What's included

• All three premium videos (~5.7 hours of in-depth instruction)
• One-time purchase, lifetime access — buy once, keep it forever
• The complete series, designed to be watched in order, with each video building on the last

"By the end, the alphabet soup — WebAuthn, FIDO2, OAuth, ZTNA, ITDR, SLSA, SBOM — will feel concrete. You'll know what each one is for, where it sits in the stack, and what problem its absence creates."

Frequently asked questions

Is this cybersecurity course for beginners? No. It's an advanced course for engineers and practitioners. We assume you already understand HTTPS and MFA, then go a layer deeper into how large-scale defenses are actually built.

What background do I need? A working knowledge of how the web and authentication function. If you can explain what HTTPS and MFA do, you're ready.

Is the material up to date? Yes. The series covers the most current breaches, regulations, and defenses, including AI/LLM security and software supply-chain attacks through 2025–2026.

Do I get lifetime access? Yes. This is a one-time purchase with lifetime access to all three videos.

Will this help me pass a certification? It's not exam-focused, but the depth on Zero Trust, identity, privacy engineering, detection, and supply-chain security reinforces the concepts behind most modern security certifications.
