2. Question Two SEM Ltd. is a company that operates an online service 24/7 all days of the year serving 10,000 customers all over the world. SEM Ltd. suffered 90 Denial of Service (DoS) attacks since they started operating 3 years ago. Every time this attack happens, it causes losses of £1 per customer, as their services are not available to their customers until SEM Ltd.’s IT team manage to relaunch the online platform. An off-the-shelf DoS mitigation appliance costs £300,000 per year, and SEM is more concerned about the company’s finance status than customer confidence.
a. Conduct a quantified assessment, including a clear description of the metrics used, of the risk SEM Ltd. faces, and decide the most adequate risk treatment, clearly identifying both the name of the risk treatment action and its rationale.
b. As an alternative to the off-the-shelf DoS mitigation appliance, SEM Ltd. are also exploring cloud computing, so that they could elastically expand the instances of their service as a way of replicating it and becoming less vulnerable to DoS. However, SEM Ltd. are worried about whether they will be able to completely remove data from the cloud when needed. What are the main challenges that make it difficult for SEM Ltd. to delete data from the cloud?
