Increasingly, computer networks cannot be considered without the important issue of security; without secure networks, businesses, commerce and communications would all fail. This University of Essex course addresses the need for modern computer network professionals.

Students cover topics such as current and future internet protocols, programming networked services and securing these systems. Essex offers a strong practical element through laboratory programmes in software engineering and in computer networking; laboratory work in security includes unique environments where the techniques of the attackers can be observed and stopped using specialist security tools.
