COIT20262 - Advanced Network Security

General Information

Unit Synopsis

In this unit, you will learn how to protect the confidentiality, integrity and availability of information and network services in business organisations. You will study the fundamental cryptographic techniques that many of the security mechanisms are built upon. You will also study network security attacks, including malware, denial of service, and application vulnerabilities, and the corresponding countermeasures. Through computer laboratory activities, you will gain hands-on experience in analysing attacks and deploying defences, including securing web applications, establishing access control mechanisms, and applying encryption in wired and wireless networks.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

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 Postgraduate 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. Written Assessment 35%
2. Online Quiz(zes) 25%
3. Written Assessment 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%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student emails.
Feedback
Software was difficult to use on a Mac, as the instructions were out of date for the latest Mac version.
Recommendation
Update the software instructions for the latest operating systems, while also making it clear that Windows is the only environment supported by teaching team (as the computer labs only have Windows).
Action Taken
The Unit Profile now makes it clear Microsoft Windows is required. However, there are instructions provided for Windows, Mac and Linux.
Source: Teaching team, student feedback.
Feedback
Workshop tasks in first few weeks are too time consuming or complex.
Recommendation
The early workshop tasks are important for understanding later tasks. Lecture content should be reduced so that some more time can be spent explaining the workshop tasks.
Action Taken
In the first 3 weeks of lecture, the number of slides has been reduced by about 40%. Combined with changes based on the new textbook, the reduction has allowed focus on key concepts in the lecture, reducing coverage of some technical detail and less important concepts. The key concepts are aligned with the corresponding tutorial (workshop) tasks.
Source: Teaching team, Self-reflection.
Feedback
Customised online textbook is hard to access and is getting out of date.
Recommendation
Review options for a new textbook, either a different book or another customised online textbook that uses new versions.
Action Taken
A different, newer textbook was selected and the lecture content updated to align with that textbook. Also, a second book created by the the unit coordinator and focusing on the practical tutorial tasks (essentially a lab manual) is freely available to students.
Source: Student evaluations and Moodle forum posts by students
Feedback
Some of the tutorial tasks are hard to follow, as they rely on tools not seen before (e.g. Linux commands) and/or assumed networking knowledge.
Recommendation
While the written instructions are detailed, they can be quite long. Consider providing short additional video demonstrations to introduce the new tools and review the assumed knowledge.
Action Taken
Nil.
Source: Staff feedback, analysis by unit coordinator
Feedback
Online quizzes may not be encouraging continuous study or accurately reflecting student performance.
Recommendation
Include in-class quizzes, which should encourage students to prepare and attend tutorials, as well as provide accurate assessment of their own knowledge.
Action Taken
Nil.
Unit learning Outcomes

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

  1. Explain vulnerabilities and attacks, as well as their countermeasures
  2. Use and compare cryptographic techniques for securing computers and networks
  3. Design security controls for organisations, such as firewalls, authentication, and access control
  4. Develop and deploy network security technologies, including encryption software, VPNs and wireless security
  5. Assess emerging threats and security controls.

The Australian Computer Society (ACS) 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 7 (the SFIA code is included):

  • Information Security (SCTY)
  • Security Administration (SCAD)
  • Information Assurance (INAS)
  • Specialist Advice (TECH)
