Explore Cybersecurity
Cybersecurity examines the protection of digital systems through risk-based controls. This subject guide introduces the questions, methods and practical work that help learners understand the field before choosing a formal course of study.
A strong starting point is to connect network security with cryptography. The first develops a foundation for reasoning; the second provides a setting in which to test ideas. Keep a learning journal that records assumptions, sources and questions that remain unresolved.
Four areas to investigate
Network security
Connect network security to the study of the protection of digital systems through risk-based controls. Compare an introductory explanation with a worked example, then describe where the approach is useful and where it may fail.
Cryptography
Connect cryptography to the study of the protection of digital systems through risk-based controls. Compare an introductory explanation with a worked example, then describe where the approach is useful and where it may fail.
Secure coding
Connect secure coding to the study of the protection of digital systems through risk-based controls. Compare an introductory explanation with a worked example, then describe where the approach is useful and where it may fail.
Incident response
Connect incident response to the study of the protection of digital systems through risk-based controls. Compare an introductory explanation with a worked example, then describe where the approach is useful and where it may fail.
Learn through inquiry
Threat-model a fictional online service and test defensive controls in an isolated lab.
Begin with a question narrow enough to investigate. Decide what evidence would support an answer, document the method and explain what further work would be needed.
