COIT11238 - Networked Infrastructure Foundations

General Information

Unit Synopsis

This unit will provide you with the foundation knowledge of computer and network infrastructure that underpins Information and Communication Technologies (ICT) in modern organisations. You will study networking essentials including virtualisation, wireless networks, cloud computing, cyber security, and risk management. By the end of this unit, you will be able to build and manage basic computer networks. You will conduct hands-on practical activities with industrial-grade networking equipment and cyber security tools to enhance the security of built networks.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Online Quiz(zes) 30%
2. Written Assessment 30%
3. Portfolio 40%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Explain the role of hardware and software components in computer networks
  2. Recognise the importance of protocols, standards, and layered architectures in building computer networks
  3. Explain the selection of network components, topologies, and technologies to meet business requirements
  4. Describe challenges and solutions in securing computer networks and infrastructure
  5. Interpret the use of forwarding and encapsulation to deliver data securely in computer networks
  6. Discuss techniques for managing cyber security, documenting, and troubleshooting computer networks.

The Australian Computer Society (ACS), the professional association for Australia's ICT sector, recognises the Skills Framework for the Information Age (SFIA). SFIA is adopted by organisations, governments, and individuals in many countries and provides a widely used and consistent definition of ICT skills. SFIA is increasingly being used when developing job descriptions and role profiles. ACS members can use the tool MySFIA to build a skills profile.

This unit contributes to the following workplace skills as defined by SFIA 8 (the SFIA code is included):

  • Network Support (NTAS)
  • IT Infrastructure (ITOP)
  • Security Administration (SCAD)
  • Systems Installation/Decommissioning (HSIN)
  • Problem Management (PBMG)
  • Information Security (SCTY).

The National Initiative for Cybersecurity Education (NICE) Framework defines knowledge, skills and tasks needed to perform various cyber security roles. Developed by the National Institute of Standards and Technology (NIST), the NICE Framework is used by organisations to plan their workforce, including recruit into cyber security positions.
