INFORMATION AND NETWORK SECURITY - 2021/2
Module code: COMM048
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
The module introduces general information and network security principles, challenges and goals and then focuses on main security mechanisms and protocols for protecting network communication across different layers of the Internet protocol stack. This will include discussion on various attacks on the networks, penetration testing tools and possible countermeasures to ensure protection of authentication, confidentiality and end-to-end security of communications. In labs students will be able to practice experience with various network security protocols and tools.

|School-timetabled exam/test||IN-SEMESTER TEST (INDIVIDUAL) (1 HOUR)||20|
The assessment strategy is designed to provide students with the opportunity to demonstrate that they have achieved the module learning outcomes.
Thus, the summative assessment for this module consists of:
· An individual in-semester test with a set of questions that students are required to answer.
This addresses LO1 and LO2.
· An individual coursework with a set of theoretical and practical tasks.
This addresses LO1, LO2 and LO3.
Formative assessment and feedback
Lecture slides are used extensively in the lectures with each lecture consisting of a number of slides explaining the theory and showing the examples. Solutions to lab exercises are explained during the lab session and provided to the students.
- The aim of this module is to equip students with background knowledge and practical experience of modern information and network security mechanisms, including widely used network security protocols and technologies. The module will explain various attacks on the network communications and demonstrate the use of appropriate protection mechanisms. The module will cover theoretical foundations of modern information and network security mechanisms and practical understanding of those mechanisms with their application in the real world.

Overall student workload
Lecture Hours: 15
Laboratory Hours: 10
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Help students understand the nature of information and network security, including main principles, challenges and goals
- Explain threats and attacks arising in the context of network communications
- Explain the functionality of network security protocols and relevant protection mechanisms
- Enable students to apply existing security mechanisms and protocols for the protection of network communications
The learning and teaching methods include:
- Lectures (15 hours) using detailed lecture slides to gauge the students’ understanding
- Labs (10 hours) using computing labs, exercise sheets and their solutions.
Students will be expected to distribute the remaining workload on self-study, preparation for lectures and labs, preparation for the in-semester test and submission of the coursework.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
