You have been recently hired as a network security analyst for a small

accounting firm. The firm realizes that it needs help to secure its network and customers’ data. With your background and skills, the firm is looking to you to provide guidance. In addition to helping the firm secure its network, the firm requires that you obtain your CompTIA Security+ certification within 60 days of being hired.
In addition to the owner, who serves as the overall business manager, there are about 20 people on staff:
➢ 10 accountants
➢ 3 administrative support specialists
➢ 1 vice president
➢ 1 financial manager
➢ 2 interns
There is also one IT support technician on staff, who has basic computer hardware and networking knowledge. He has requested that the firm create a website, hosted internally, so that new customers can get information about the firm. This will be important to remember as you complete your final project.
The firm has a simple network. There are 20 computers and two multipurpose printers. All computers and printers are connected wirelessly to a NETGEAR MR814 device. This router is connected to a Motorola SB3100 cable modem. Staff email accounts are set up through the company’s Internet provider. Employees use a combination of Microsoft Outlook and standard web browsers to access their e-mail. The owner uses his personal iPad during work hours to check and respond to email messages.
Prior to your hiring, the firm hired a network cabling contractor to run Cat 6 cables from the central wiring closet to all offices and cubicles. The firm wants to move away from using wireless as the primary network connection, but wants to keep wireless access for customers coming to the building. The technician who did the wiring mentioned to your supervisor that he should look into setting up a Windows Server domain to manage user access, instead of the current peer-to-peer network. He also recommended that the firm invest in a managed switch and a firewall, and look into having some backups. The internal IT support technician agreed with these recommendations but needs your help to implement them.
You’ve been asked to assess the current vulnerabilities and provide a recommendation to the firm’s owner on how to better secure the network infrastructure. Now that you are aware of the firm’s history, your assessment and recommendation should provide specifics about the network security settings that must be implemented and the equipment that must be procured, installed, and configured. The firm’s owner has a basic understanding of computing, so it is important that you explain the technical issues in layman’s terms.

I. Vulnerability AssessmentsUse this secTon to describe any network security vulnerabiliTes. Use the scenario along with industrystandards and best pracTces to idenTfy the vulnerabiliTes. Describe why it is vulnerable and what theimplicaTon is if it is not miTgated.±he example below is of the physical security of a warehouse. (In your submission, you will have severalvulnerabiliTes idenTFed and miTgated.)At the Alpha Warehouse, we discovered one key vulnerability to the physical security. This was the use ofa Master Lock combina±on lock to secure the back entrance. While the use of a combina±on lock canlimit the number of people who can enter to those given the combina±on, vulnerability in the design ofthese locks was recently exposed. By using “a process that requires less than two minutes and a minimalamount of skill to carry out” [1], would-be thieves can access the warehouse through a single entrance.While the thief will need to also have access to an online calculator that helps stream the process, theprevalence of smartphones makes this a small hurdle to jump, allowing any interested par±es quickaccess to the Alpha Warehouse.
