Identify and justify the choice of technology (or technologies) you are proposing to use to upgrade the IT Infrastructure of your selected organization.

Assignment Task
This assignment is worth 100% of the total marks for the module.
To make this assignment more relevant and interesting for you, you will select your own realworld organization (and thus case study) and then apply the concepts and techniques you have
learned from this module to that case study. The case study you select must not have been
used by you, or any other student, in any other module current or historic. Please ensure you
check your selected organization and the scope of the case study with your tutor before starting.
Your selected organization for this case study intends to upgrade their current IT infrastructure
to meet the organizational IT needs in the 21st century. You have an option of using a
technology of your choice or technologies such as Internet of Things, Cloud Computing, Content
Centric Networking, or Software Defined Networks for this upgrade. You as an IT Lead have
been asked to write a report for the management justifying viability of the proposed future IT
infrastructure in the context of its security.

Task 1
1a) Discuss briefly the profile of your selected organization, its existing IT infrastructure, and
pertinent issues with the current infrastructure to justify the need for an infrastructure upgrade.
1b) Identify and justify the choice of technology (or technologies) you are proposing to use to
upgrade the IT Infrastructure of your selected organization. You are expected to briefly compare
technologies to justify your choice.
1c) In the context of proposed future IT infrastructure for your organization, discuss critical
assets (including information assets) that will need protection, and list vulnerabilities related to
each of the identified assets.

Task 2
2a) Risk analysis lies at the heart of any successful IT project. Through arguments backed by
literature, justify the importance of risk analysis phase in any IT project. Also discuss what risk
analysis process in relation to IT infrastructure projects entails.
2b) Critically evaluate a range of pertinent security risks posed to the selected organization in
context of their proposed IT infrastructure upgraded through the technology of your choice. Also,
briefly discuss the proposed protection against those risks.
2c) Conduct a detailed risk analysis of your organization based on the risks evaluated in Task

Task 3
3a) Critically evaluate key aspects of the security policy of your selected organization (or an
organization of a similar profile and size) also discussing how effective the policy is in protecting
against security risks evaluated in Task 2b.
3b) Cryptography acts as a key measure in tackling a range of security threats. Discuss a
cryptographic approach (or a combination of approaches) you are proposing for your
organization to adopt and justify your choice by briefly comparing your approach against other
available approaches. Explain in what areas of your organization’s future IT infrastructure you
will use the proposed cryptographic approach.
(1000 words)
Task 4
4a) Provide a brief assessment of the security of your proposed IT infrastructure using layered
security approach.
4b) Critically evaluate legal, social and ethical issues in relation to the security of proposed IT
