Security of Operating Systems and Networks – Individual Assignment

This individual assignment focuses on the security of operating systems and computer networks. Students are required to produce a professional technical report of approximately 2,000 words demonstrating a deep and systematic understanding of operating-system security, networking functions, security threats, vulnerabilities and practical security testing. The assessment carries 50% and forms 100% of the module assessment. Students are expected to support their work with appropriate technical evidence, images showing practical steps and relevant sources. The assignment uses a business scenario involving Net-Tech, a small and medium-sized technology-services enterprise. The organisation is concerned about the security of its proposed system, including operating-system attacks such as buffer overflow and network threats such as hacking and phishing. Students are required to investigate, design and experiment with the features and functions of a web server used to serve the company's website, while assessing the security landscape and presenting findings that can support appropriate organisational security decisions. As part of the practical work, students must create a prototype Net-Tech network test rig. This includes creating two users, with one configured as a superuser and another as a standard user, applying appropriate baseline security measures, installing suitable software and identifying vulnerabilities, using appropriate tools to conduct security tests, and writing scripts to automate repetitive tasks. Students must document assumptions and parameters used within the project, including further security implementations and recommendations such as the use of a suitable database for a database-driven website. The report is structured around introduction, background research, pre-engagement, engagement and post-engagement activities. The introduction should explain the business scenario, assumptions, aims, objectives, deliverables, available skills and resources, constraints and project plan. The background research should address common vulnerabilities, threats, risk models, security-testing approaches, relevant attack and testing tools, legal and organisational requirements, and ethical, social, professional and sustainability considerations. The pre-engagement section covers the test-rig setup and testing strategy. The engagement section requires practical comparison and demonstration of operating-system and network security, including user authentication, file and directory permissions, protection against stack-overflow attacks, network weaknesses, operating-system discovery, firewalls, listening ports, network statistics, prevention of denial-of-service attacks and scripting for automation. The post-engagement section requires a summary of the work, deductions and limitations, mitigation measures and recommendations, and personal reflection. The assessment requires students to use relevant sources, provide a bibliography and demonstrate appropriate analysis, evaluation and reflection. The assignment is designed to assess learning outcomes relating to knowledge of network security threats and the development of complex software and scripts relevant to operating systems and computer networks.

Digital Security Risk and Audit 2,000 words

Digital Security Risk and Audit – Information Security Audit of ABC Air

This individual coursework for the Digital Security Risk and Audit module requires students to prepare a 2,000-word information security audit report based on a case study involving ABC Air, a small aircraft service company responsible for aircraft maintenance for civil operators. The company records information including aircraft flying hours, servicing time, engineers' man-hours and related maintenance activities. An external contractor has also provided a report outlining a possible solution for ABC Air. Students are required to assess the information security risks associated with the scenario, complete an information security audit and produce a professional report, clearly identifying any assumptions made during the analysis. The assessment requires students to examine risk assessment, identification and analysis as part of the audit process. A suitable auditing approach must be selected and justified, with students considering either a general risk-based approach or a specific control-based approach. The report should explain why the selected approach is appropriate for the ABC Air scenario and demonstrate how it can be applied to the organisation's information security environment. The coursework also requires consideration of potential cyber attacks and their use within an integrated fault event analysis. Students must identify relevant information security threats and examine how an attack could affect the organisation and its information assets. The report should further identify appropriate standards, best practices or guidelines that could be used to mitigate information security breaches. These should be critically evaluated, including discussion of their advantages and disadvantages rather than simply being listed. The assessment develops students' ability to apply information security governance and audit practices within legal, ethical and professional contexts. It also requires consideration of recognised industry frameworks such as COBIT and international standards including the ISO 27000 series. Students are expected to perform systematic risk assessment and analysis, critically evaluate information assurance reference models, and select appropriate information security audit strategies for complex real-world scenarios. The marking criteria place particular emphasis on the quality of the information security audit, identification and adoption of appropriate international standards and frameworks, and critical evaluation of the benefits and limitations of security audit frameworks. The assessment allocates 20% to identifying and applying an appropriate audit approach, 50% to completing the conceptual information security audit and assurance, and 30% to interpreting and critically evaluating information assurance reference models. The report is an individual assessment and must be submitted as a PDF through Aula/Turnitin. The brief states that APA referencing should be used for the work and that all sources and any AI tools used must be acknowledged.
