Computer Security Operating System and Network Security 1. Airport Security . You are chief security officer for the main airport in your city. Computer Security for airports is both very complex and very important. It is important because airports are high profile pieces of national infrastructure that are frequently targeted by criminals, protestors and terrorists. It is complex because a lot of different types of people use their networks and computer systems: Airport staff that are directly related to high security activities such as air traffic control or passenger security checks Other airport staff, for example, back office staff and baggage handlers Staff of companies that operate from the airport, including airlines as well as shops and restaurants Passengers, who use airport WIFI and need to know about flight times and other information Many of the systems used by these different people will be different from each other (e.g. the baggage handling system or a restaurants booking system), but there are systems, such as the flight take off and arrival schedule that almost everyone needs access to, though in different forms and with different levels of access. As a security officer you need to keep up to date on possible threats to the organisation. For this coursework, you should research 3 specific threats that could affect an airport (e.g. a specific piece of malware or a specific type of DDoS attack), describe that threat and suggest a security mechanism to protect against it, and explain how it will defend against the attack. All sources must be fully referenced
