Enterprise Networking and Security
Run by School of Computer Science and Electronic Engineering
20.000 Credits or 10.000 ECTS Credits
Organiser: Dr David Edward Perkins
Overall aims and purpose
This module predominantly uses the “Enterprise Networking, Security, and Automation” section of the Cisco CCNA course and covers wide area network (WAN) technologies and quality of service (QoS) mechanisms used for secure remote access along with the introduction of software-defined networking, virtualization, and automation concepts that support the digitalization of networks.
Students gain skills to configure and troubleshoot enterprise networks, and learn to identify and protect against cybersecurity threats. They are introduced to network management tools and learn key concepts of software-defined networking, including controller-based architectures and how application programming interfaces (APIs) enable network automation.
The theoretical content of this module is blended with a substantial number of practical exercises involving configuration of switches and routers. These exercises are carried out either in a networking lab using industry standard hardware or using the Cisco Packet Tracer network simulator which is provided to all students studying the Cisco based modules to facilitate practice at home.
Indicative content includes:
- Open Shortest Path First (OSPF) routing protocol on point-to-point & broadcast multiaccess networks.
- Network security concepts
- Access Control Lists (ACLs)
- Network Address Translation (NAT) for IPv4
- WAN access technologies
- Virtual Private Networks (VPNs). IPSec.
- Quality of Service (QoS)
- Network design
- Network management
- Network virtualisation
- Network automation
Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.
Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
Configure and troubleshoot ACLs and NAT
Explain how LANs can be linked securely
Explain how ACLs can be used for traffic filtering and security
Explain how and why NAT is implemented
Explain how network design can affect scalability
Explain the purpose and characteristics of network virtualisation
Configure and troubleshoot single area OSPFv2.
Teaching and Learning Strategy
The classroom sessions which take place in dedicated computer hardware networking rooms will include interactive lectures, group discussions, practical labs using network simulator or real hardware, individual and group work.
Most study materials are provided through the Cisco Networking Academy VLE. Other materials will be hosted or signposted on the VLE.
