Quantum Computing & Cybersecurity For Security Professionals

Explain how Shor's algorithm breaks RSA, ECDH, and DSA - and why increasing key size provides zero protection against a quantum computer
Apply Mosca's Theorem to score your organisation's quantum risk and produce a prioritised 30/90/365-day migration action plan by role
Identify every cryptographic algorithm at risk across TLS, VPN, SSH, PKI, and code signing - and map each one to its exact quantum threat level
Explain how Harvest Now, Decrypt Later attacks work and why data encrypted today under RSA or ECDH may already be in an adversary's archive
Interpret NIST FIPS 203/204/205, NSA CNSA 2.0, EU DORA, and NIS2 quantum mandates and their binding compliance deadlines by jurisdiction
Communicate quantum security risk to boards and executives using business-impact language without requiring any technical background
Requirements
No quantum physics or mathematics background required - every concept is built from first principles with plain-language explanations
No programming or coding experience needed - this is not a development course; it is a security strategy and risk awareness course
Basic familiarity with cybersecurity terminology (encryption, certificates, VPNs, PKI) is helpful but not required to enrol
An open mind toward technical concepts explained at a conceptual level - you will understand the mathematics intuitively, not by calculation
Access to a computer or mobile device to download the 7 supplementary research papers and reference guides included with the course
Description
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.You will understand Harvest Now, Decrypt Later (HNDL): why data encrypted today under classical cryptography may already be sitting in an adversary's archive, and why this creates present-day compliance liability under GDPR Article 32, DORA, and NIS2.You will map every vulnerable algorithm - TLS 1.3, IPsec, SSH, PKI, code signing, DNSSEC, S/MIME - to its quantum threat level, and understand exactly what breaks and what survives.The course includes 7 supplementary papers in LaTeX for students who want the formal mathematics, 7 downloadable reference guides, section quizzes, and a capstone assessment with certificate of completion.No prior quantum knowledge needed. If you manage, architect, or secure systems that rely on cryptography - this course is your mandate briefing.
Security professionals - SOC analysts, security engineers, penetration testers - who need to assess and communicate the quantum threat to their organisation's cryptographic infrastructure,CISOs, IT managers, and security architects responsible for planning post-quantum cryptography migrations and presenting quantum risk to boards, executives, and audit committees,Compliance officers and risk managers working under GDPR, DORA, NIS2, HIPAA, or CNSA 2.0 who need to understand quantum-related regulatory obligations and enforcement timelines,IT administrators and infrastructure engineers who manage TLS, PKI, VPN, SSH, or code signing systems and need to assess which components are quantum-vulnerable and in what order to migrate them,Security consultants and advisors who need a rigorous, up-to-date briefing on the quantum threat to present to clients or incorporate into risk assessments and security roadmaps,Professionals preparing for post-quantum cryptography certifications or seeking foundational knowledge before progressing to the NIST FIPS 203/204/205/206 implementation courses in this track
