Networks and Security

Module overview

This module introduces students to the principles of layered communication protocols, the architecture of the Internet and the TCP/IP model. This is complemented with a multi-disciplinary overview of cyber security, which considers not only technical measures and defences, but also legal, management, crime, risk, social and human factors.
