Unit rationale, description and aim
With the increasing reliance on technology, it is becoming more and more essential to secure every aspect of online information and data. Therefore, network security is very critical for any organisation and is essential to protecting client data. This unit covers the advanced network security concepts that require to developing students’ knowledge and practical skills in digital communication and security.
This advanced unit explores the theoretical foundations and current landscape of cryptography, covering essential concepts required to understand complex security challenges in networked environments. The unit contents include networking concepts, classical cipher design and analysis, key management, digital signatures and hash algorithms, wireless security, web security, email security and data stewardship. The unit also focuses on applications of network security tools to prevent or detect security attacks. The aim of this unit is to provide students with a good understanding of network security issues and the importance of data stewardship, as well as the knowledge and skills they need to plan, design or implement in order to secure a networked environment.

Assessment strategy and rationale
A range of assessment procedures will be used to meet the unit learning outcomes and develop graduate attributes consistent with University assessment requirements. The first assessment item consists of a number of weekly practical tasks which will give students the opportunity to implement their theoretical knowledge to solve problems in a practical environment. The second assessment item is a design report, where students will write a report on a given case study. The purpose of this assessment is to assess the students’ ability to apply their theoretical knowledge and design an effective solution to countermeasure security threats through collaborative learning. The final assessment is an open book exam, where students will study several case studies, critically analyse them and answer a number of open-ended questions. The purpose of this assessment is to test students’ ability to apply professional skills and practices in solving numerous problems.
The assessments for this unit are designed to demonstrate the achievement of each learning outcome. To pass this unit, students are required to: obtain an overall mark of at least 50%.

Assessment Task 3: Exam
This assessment task tests the students’ grasp of both theoretical and practical aspects of the unit. The students will study several case studies, critically analyse them and answer a number of open-ended questions. They also have to use network security tools to investigate the given scenarios and justify the outcomes.

Learning and teaching strategy and rationale
This unit is delivered through Attendance and Online modes using a single, integrated learning and teaching strategy designed to ensure equivalent learning outcomes and a comparable learning experience for all students, while supporting diverse learning needs and maximising access.
Across both modes, learning activities are intentionally aligned to the unit learning outcomes and assessment tasks, and are underpinned by active learning, guided engagement with disciplinary knowledge, opportunities for peer interaction, and regular, timely feedback. While the mode of delivery shapes how students participate, the pedagogical intent, expectations and standards remain consistent.
In Attendance mode, students engage in weekly face-to-face classes at designated locations, supported by preparatory activities prior to workshops and opportunities for consolidation following classes. Online learning platforms are used to complement face-to-face teaching through additional resources and learning activities.
In Online mode, students engage with the same core content and learning outcomes through a combination of synchronous and asynchronous activities, including structured discussions and applied learning tasks that support learning in professional contexts.
Across both delivery modes, students should plan to commit approximately 150 hours to this unit over the semester, including participation in learning activities, independent study, readings and assessment preparation.
