Secure Network Systems

Network security is the activity associated with the detection and prevention of unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. In this module, the learner will evaluate common cyber security threats and defense in depth techniques to defend against these threats. In particular, the module will provide the learner with the skills to apply and use various computer protection components such as Firewalls, VPN and Intrusion Detection and Response Systems (NIDRS) and security techniques such as zoning and encryption. At the end of this module the learner should have the ability to operate and interpret information collected from various network security equipment and network tools to implement a secure network architecture.

Lecturer: Dr. George D. O'Mahony

Important Information

Entry Requirements

A level 7 qualification with modules on Computer Networking, where the applicant has an understanding of how networking protocols work together to achieve data communications and the lifecycle of a packet as it traverses a computer network. This includes an understanding of a computer network, its architecture, protocol stacks and the process of data segmentation and encapsulation. In addition, the principles and structure of Internet Protocol (IP) addressing and sub-networking, along with building and configuring a basic network utilizing common network utilities would be advantageous.

Student Stories

“Cyber Skills provides the building blocks needed to set you up for a career in Cyber Security. Online learning and the ability to re-watch a lecture has given me the freedom to work a full-time job and also fit in my extra-curricular activities.”
Colm McSweeney, Secure Network Operations Pathway

“Security is paramount on financial systems, and it cannot be implemented as an afterthought, I wanted to reinforce my knowledge on Cyber Security, to continue to design robust systems capable of sustaining today’s sophisticated attacks.”
