Course Overview

Managing and maintaining network and information security is an essential aspect for the development of the global economy and is crucial to the success of all companies, particularly in the current climate.

Managing and maintaining network security poses a huge challenge for businesses today and is forcing them to look for next-generation security solutions to contain cyber threats, with the result that there has been a 40% increase in cybersecurity vacancies over the past two years. Security is perceived as one of the key challenges of mobility, with a higher number of devices and connected endpoints increasing organisations' exposure to cyberthreats.

This postgraduate diploma prepares students with computing backgrounds for employment in the IT industry with a specific focus on addressing these networking and information security challenges.
