Course Overview

In this course the learner will look at the component parts of digital communications and interoperability with IT networks, hardware, firmware and software components. The inherent insecurity of the internet will be described and discussed. What are the basics of computer science and technology? How do computers communicate with one another? How can networks communicate and how can we plan their security architecture in a more proactive and organised manner?

The second half of this unit will look at security planning and core concepts including ‘security engineering’, systems hardening and cyber resilience.
