Internet of Things (IoT) devices can be used to sense and share data from its surrounding environment for various purposes that can be useful for both humans and machines. These can be as simple as measuring the temperature of a room or more critical tasks such as monitoring the heart-rate of a sick patient in a hospital. The advances in hardware design, communication protocols, and computing technologies have created an ecosystem of a variety of IoT devices by numerous vendors and underlying infrastructure.
The network diagram provided (Figure 1 – see below) illustrates the various IoT devices integrated in a medium sized organisation’s IT network. Table 1 (see below)provides detailed specifications of the devices including hardware, software, and firmware details. Although the network is already secured with various defences, there are several problems that can lead to the organisation being compromised by cyber criminals.
You have been hired as an external cyber security consultant to analyse the network for security issues and recommend solutions to mitigate these risks in the form of a technical report. The report is intended to be submitted to the management committee of the organisation. Therefore, highly technical concepts must be further described to a level understood by a novice audience.
Your report should consist of the following:
Please note that discussions related to security policies are beyond the scope of this assessment and therefore should be excluded from your report.
Each of the following criteria are worth 8 marks, with a total of 40 marks for the whole assessment.
