Security Evaluation – Secure Design, Security Audit and IoT Security Recommendations
This individual coursework for the Security of Emerging Connected Systems module requires students to prepare a 2,000-word technical report evaluating secure design, security auditing and security recommendations for an organisation developing Internet of Things (IoT) devices and systems for home and workplace environments. The assessment is worth 10 credits and requires students to provide practical and evidence-based guidance to the client’s software development team. The report is assessed across secure design and development methodology, security audit methodology, security recommendations and overall report structure. The first major section addresses Secure Design and Development Methodology. The client wants to incorporate secure design principles into its software development workflow and therefore requires an overview of possible secure design processes relevant to IoT. Students must evaluate the strengths and weaknesses of different approaches and provide a justified recommendation for a process that would be appropriate for the client. The emphasis is on integrating security into the design and development of systems rather than treating security as a separate activity after development. The second section focuses on Security Audit Methodology. The client wants to complement its secure design process with a security audit of the final developed system. Students must provide a practical guide explaining how a security audit could be performed, including the overall testing methodology and the purpose of each stage. The brief identifies methodologies such as PTES and OWASP as examples. Students are also expected to discuss different approaches and evaluate their respective strengths and weaknesses. The third section concerns Security Recommendations and requires students to demonstrate the implications of strong secure design and auditing through an IoT security case study. Students must research a security vulnerability affecting an IoT device, explain the vulnerability and identify where the security flaw was introduced. The report must then examine which parts of the secure design and audit processes were not implemented correctly and evaluate the resulting impact on the security of the product. The report is intended for a technical audience, specifically the client's software development team. Students are expected to use an appropriate technical structure and language, support their arguments and analysis with references, and use APA referencing. The assessment also encourages appropriate diagrams to support the written content. The report structure component accounts for 10% of the assessment, while Secure Design and Development Methodology, Security Audit Methodology and Security Recommendations each account for 30%. The coursework assesses learning outcomes relating to defence-in-depth solutions for technical internet security vulnerabilities, secure private networks for IoT and BYOD, and current research and technological advances in network security. These outcomes connect the assignment to practical IoT security engineering, secure development, security auditing and emerging network-security practices.
