I have this Information Security Project. It would be greatly appropriated if you could help with some information on how i would answer the 5 questions in the business challenge section using SDLC method.

FINAL PROJECT BUSINESS CHALLENGE EXECUTIVE SUMMARY Customer Name: MacArthur Corporation Industry: Building materials distribution Location: Headquartered in Minneapolis, Minnesota, with 36 distribution locations and two manufacturing facilities in the central and western United States Number of Employees: 500 BUSINESS CHALLENGE Relieve network congestion and maintain performance without adding branch bandwidth Strengthen and centralize web security Smooth network performance without additional bandwidth or operating costs Dependable, cloud based centralized Internet security for remote users Reduced help desk support r equirements MacArthur Corporation is a distributor of roofing, siding, HVAC, and other building materials for residential and commercial construction. Headquartered in St. Paul, Minnesota, the company maintains 36 distribution locations and two recently acquired manufacturing facilities in the upper Midwest and mountain states and on the west coast. With a basic hub - and - spoke architecture, MacArthurs network connects the remote sites to the companys data center in St. Paul for access to all enterprise resource planning, email, and other applications as well as access to the Internet. According to Jon Reineke, director of information technology, the companys migration to different technology began four years ago. With the previous vendors routers, we were having three or four outages a week, he says. By replacing that equipmen t with an Integrated Services Routers (ISRs), Reineke and his team reduced outages to less than one per month. The ISR also allowed them to provide secure VPN links for employees laptops at the remote sites. They deployed antivirus and ant spam email security solutions and a Web Security Appliance. Soon after, they also added a Unified Communications Manager, they named Call Manager , to their infrastructure in St. Paul to begin centralizing voice communications management network wide. E ventually, however, it became clear that backhauling all of MacArthurs network traffic through St. Paul was not a strategy for the long haul. The St. Paul facility is served by a 30 - megabit Multiprotocol Label Switching (MPLS) link as well as a 50 - megabit Internet connection, but the volume of traffic through the site was slowing performance across the network, or soon would. Some of the branches are limited to a T1 connection. At one of the manufacturing facilities, some 60 users were consuming most of th e available bandwidth just using the companys centralized ERP applications. Meanwhile, on the security side, the solutions localized at the branches were not providing adequate Internet access control and network security. Many of our remote users have company laptops, says Reineke, and you cant control everything they do on the web with those PCs, no matter how hard you try. So we had users going to compromised Internet sites. Others were downloading music and other media. They were bringing back vir uses and malware on their machines. The result was lots of downtime for those users, and lots of time spent by our IT staff of just three people fixing infected PCs. Routing remote employees Internet use, whether for company or personal purposes, back to headquarters to secure the network, would
