Develop your understanding of network management and cyber threats

This course delves into five generations of IT and IS to give you a historical perspective on the development of technologies and better understand the emerging digital opportunities for organisations today.

Discover the emergence of the IT industry

Stepping back 80 years to vacuum tubes in the first generation of computers, this course will walk you through five generations of innovation. You’ll discover the invention of transistors, integrated circuits, microprocessors, and artificial intelligence. You’ll have the opportunity to see where we came from, and just how far the industry has come.

Apply history to modern cyber security

Through a historical lens, you’ll have a chance to explore IT infrastructure, web servers, intranet, extranet, URLs, domain names, web systems, languages, application infrastructure and media standards. Understanding the history means you can better assess the vulnerabilities, historically and today.

Explore real-world cyber threats

In the second week of this course, you’ll look at common types of cyber threats, where they come from and how they’ve evolved, as well as non-web-based attacks.

By the end of the course, you should have a clearer understanding of network management and how it relates to cyber threats.
