Question

The city of Hastings, KY wants to set up a secure WAN to connect all of their government buildings. They also want to provide free and secure wireless access to the residents that live within the downtown city limits (the free wireless access should provide access to the residents of local government services and general Internet access). The city currently uses leased lines through the local phone company to connect the 10 government buildings. They also want to provide access to the schools in the city; 5 elementary schools, 2 middle schools,
and 2 high schools. The total student population is approximately 9,600. By setting up their own WAN they expect to save at least 50% over the cost of the leased lines that they currently utilize. Below is a map of the city with the government building locations, and the schools. The T1 lines, there is only 1 line that connects the buildings in the sequence shown (blue lines), cost $347 per month per connection (each building has at least 1 connection, some have 2 – each in and out is one connection). When you recommend a new solution, consider
redundancy/fault tolerance, cost, and suitability for the city. Also, each school is connected to the closest city government building using a leased line that costs the same as the T1 lines ($347 per month).

Determine the following:

1.) What hardware upgrades would they need, and would you suggest to the network (both at the LAN and
WAN level).
2.)What would you recommend that the city uses for its Wireless WAN access across the 12 square mile
area of the city (which encompasses all of the buildings in the diagram)? Make sure to show the
coverage, including a site survey (once again, you will have to investigate coverage of each wireless
router).

3.) When recommending equipment for the wireless public network, what type of configuration would you
recommend?

Explanation / Answer

The city of Hastings, KY wants to set up a secure WAN to connect all of their government buildings. They also want to provide free and secure wireless access to the residents that live within the downtown city limits (the free wireless access should provide access to the residents of local government services and general Internet access).

The networking, security, financial and management teams, as well as the network's users, must all be involved and kept in the loop. Issues such as required changes to procedures and processes, test dates and any expected downtime need to be flagged as soon as possible to all affected.

Vendors and specialists in both internal and external applications should take part in the process, too. Differences over whether the right decision has been taken need to be put to one side to ensure the approved plan is implemented well. To help this process, the security team should highlight any concerns early on in the planning stage so that mitigating solutions can be agreed on. I would also recommend that a consistent vocabulary and terminology is established to avoid any confusion when discussing new technologies and equipment.
