Unit 4: Cyber Security and Encryption
Protect digital assets through risk assessment, cryptographic controls, and security policies assessed in an external timed task.
What is Unit 4 — Cyber Security and Encryption?
The Cyber Security and Encryption (Unit 4) unit addresses one of the fastest-growing technology fields, combining threat analysis with practical security controls.
Learners study encryption methods, authentication mechanisms, and organisational policies that mitigate cyber risk in connected enterprises.
Assessment is delivered as an external timed task requiring applied problem-solving under examination conditions.
Core Strategic Value
- •Threat Intelligence: Classify vulnerabilities, attack vectors, and actor motivations.
- •Cryptographic Controls: Explain symmetric, asymmetric, hashing, and certificate use cases.
- •Governance: Design policies for access, awareness training, and incident response.
