This assignment refers to Risk Assessment Lab scenario we completed in class. If you need to refresh your memory on the specifies of that lab, the lab is located in Files on our course Canvas site. Answer each question asked in each case project below fully and completely. Case Project 1 Six months after your initial security audit, the credit union's manager contacts you to conduct a follow-up security audit. He mentions that his networking team followed your suggestion for improving the LAN and WAN security. However, since then several wireless components have been added to the network, including an access point at each of its two locations. These access points allow employees to connect with the LAN and another access point at each of its locations designated for customer access. The manager doesn't even know if wireless security measures have been implemented, much less whether any measures that might have been implemented are as secure as possible. Describe at least three separate techniques that could be used to improve wireless LAN security. Among these, which do you recommend for the employee WLANs at each location, and which do you recommend for the customer WLANs? Why might the two types of WLANs differ in the method of secure transmission they use? Finally, how can the credit union's network administrators ensure that customers who bring their PDAs or laptops into the bank can access customer WLAN but cannot access the employee WLAN? Case Project 2 A year after your first visit to the credit union the manager calls you once again. His business is experiencing tremendous growth and needs to either open another branch office on the west side of town or allow their auditors and loan-processing staff to work from home. He asks you to compare the security requirements of opening a new branch office versus implementing a VPN solution (using employees' home broadband Internet connections) for work-at-home employees. As part of your comparison, identify the costs associated with these security requirements. What factors do those costs depend on? For an expansion of 10 users, which solution to you recommend
