Overview
Computer networks underpin modern communication and digital services, and network attacks can disrupt systems, expose sensitive information, and cause serious consequences for organisations and individuals. This unit introduces foundational and practical knowledge of network security principles and the mechanisms used to protect modern computer networks.
You will explore common network attacks and the protocols and techniques used to secure both wired and wireless networks. Topics include cryptography fundamentals for network security, secure communication protocols, authentication and access control, and defensive mechanisms such as firewalls and intrusion detection systems, as well as attacks like denial‑of‑service.
By the end of the unit, you will understand how security mechanisms operate within real‑world networks and how they are applied to mitigate security risks.
