Computer Science
As a network consultant, you are given the complete access to customers’ infrastructure, all features in routers/instruments, and all the customers’ data collection. You have been assigned to address the following customers’ queries:
1) Customer A is experiencing a high network traffic problem within one of its private networks. The customer suspects that the traffic is generated by computers that are infected with malicious software where it has been sending spam messages without the owners' knowledge. The customer is asking for your help to monitor the amount of traffic due to this network and possible hosts that had been infected. Analyze the necessary steps you would take to address the query and clearly state all the assumptions. Evaluate the practical data that you may consider to be included in your analysis.
