Overview

The popularity of the Internet, coupled with the explosive growth of mobile computing devices (phones, personal digital assistants (PDAs) and laptops), has led to the world of universal electronic connectivity. In this connected world, people access data and services on the Internet and communicate with each other anywhere and anytime. While this level of connectivity may bring us many benefits such as improving our quality of life and running services with global presence but with reduced costs, it does open vast opportunities for unauthorised access to data, services and other resources and for fraud and forgeries in commercial and business activities. Therefore, it is of paramount importance to increase both awareness and knowledge in protecting data and resources from unauthorised disclosure, in guaranteeing the authenticity of data in transit, and in protecting networked systems against attacks.

Aims

This course unit aims to introduce the principles and practice of cryptography and network security. It covers cryptography, network-based security threats and vulnerabilities, and practical solutions to system and network security. It is designed for students who have some understanding of computer networks and protocols, but no background in security.
