Udemy – Quantum Computing & Cybersecurity for Security Professionals

Get Started

Quantum computing is not a future problem. Governments have already signed enforceable mandates — NIST FIPS 203/204/205, NSA CNSA 2.0, EU DORA, NIS2 — with hard deadlines. Nation-state adversaries are already harvesting your encrypted traffic today, waiting for the day they can decrypt it. That day has a name: Q-Day. This course gives security professionals the technical foundation and practical frameworks they need to understand, quantify, and act on the quantum threat — with zero physics or mathematics background required.

You will learn exactly how Shor’s algorithm breaks RSA, ECDH, DSA, and every elliptic curve scheme in use today. You will learn why no key size increase protects you. You will learn how Grover’s algorithm weakens AES-128 and SHA-256, and what the safe alternatives are right now. You will master Mosca’s Theorem — the risk framework used by CISOs and government agencies worldwide — and apply it to your own organisation to produce a scored, prioritised migration plan.
