SCP Exam SC0-502 Topic 3 Question 24 Discussion

GlobalCorp is a company that makes state of the art aircraft for commercial and government use. Recently GlobalCorp has been working on the next generation of low orbit space vehicles, again for both commercial and governmental markets. GlobalCorp has corporate headquarters in Testbed, Nevada, USA. Testbed is a small town, with a population of less than 50,000 people. GlobalCorp is the largest company in town, where most families have at least one family member working there. The corporate office in Testbed has 4,000 total employees, on a 40-acre campus environment. The largest buildings are the manufacturing plants, which are right next to the Research and Development labs. The manufacturing plants employee approximately 1,000 people and the RD labs employ 500 people. There is one executive building, where approximately 500 people work. The rest of the employees work in Marketing, Accounting, Press and Investor Relations, and so on. The entire complex has a vast underground complex of tunnels that connect each building. All critical functions are run from the Testbed office, with remote offices around the world. The remote offices are involved in marketing and sales of GlobalCorp products. These offices also perform maintenance on the GlobalCorp aircraft and will occasionally perform RD and on-site manufacturing. There are 5 remote offices, located in:

New York, California, Japan, India, and England. Each of the remote offices has a dedicated T3 line to the GlobalCorp HQ, and all network traffic is routed through the Testbed office the remote offices do not have direct Internet connections. You had been working for two years in the New York office, and have been interviewing for the lead security architect position in Testbed. The lead security architect reports directly to the Chief Security Officer (CSO), who calls you to let you know that you got the job. You are to report to Testbed in one month, just in time for the annual meeting, and in the meantime you review the overview of the GlobalCorp network: Your first day in GlobalCorp Testbed, you get your office setup, move your things in place, and about the time you turn on your laptop, there is a knock on your door. It is Orange, the Chief Security Officer, who informs you that there is a meeting that you need to attend in a half an hour. With your laptop in hand, you come to the meeting, and are introduced to everyone. Orange begins the meeting with a discussion on the current state of security in GlobalCorp. "For several years now, we have constantly been spending more and more money on our network defense, and I feel confident that we are currently well defended." Orange, puts a picture on the wall projecting the image of the network, and then continues, "We have firewalls at each critical point, we have separate Internet access for our public systems, and all traffic is routed through our controlled access points. So, with all this, you might be wondering why I have concern." At this point a few people seem to nod in agreement. For years, GlobalCorp has been at the forefront of perimeter defense and security. Most in the meeting are not aware that there is much else that could be done. Blue continues, "Some of you know this, for the rest it is new news: MassiveCorp is moving their offices to the town right next to us here. Now, as you all know, MassiveCorp has been trying to build their orbital systems up to our standards for years and have never been able to do so. So, from a security point of view, I am concerned." This is news to most people, Yellow, the Vice President of Research asks, "We have the best in firewalls, we have the best in you and your systems, what are you suggesting?" The meeting continues for some time, with Orange leading the discussion on a whole new set of technologies currently not used in the network. After some time, it is agreed upon that GlobalCorp will migrate to a trusted networking environment. The following week, Orange informs you that you will be working directly together on the development of the planning and design of the trusted network. The network is going to run a full PKI, with all clients and servers in the network using digital certificates. You are grateful that in the past two years, Orange has had all the systems changed to be running only Windows 2000, both server and professional systems, running Active Directory. You think the consistent platform will make the PKI roll out easier. The entire GlobalCorp network is running Active Directory, with the domain structure as in the following list: Testbed.globalcorp.org Newyork.globalcorp.org California.globalcorp.org Japan.globalcorp.org India.globalcorp.org England.globalcorp.org Although you will be working in the Testbed office, the plan you develop will need to include the entire GlobalCorp organization. Based on this information, select the solution that describes the best plan for the new trusted network of GlobalCorp:}
