Part A: Background
Located in Mississauga the Hegelberg Dairy Headquarters (HQ) was established in 2005 by Dr. Joseph Hegelberg and his daughter Nina Hegelberg, a Ryerson graduate student in Bio- Engineering.
The company produces a wide range of dairy products (milk, yogurt, cheese, butter, ice cream) and non-dairy products such as orange juice.
The companys cheese products, Gouda and Edam, and the Ice cream product
named Hegel-Ice are among the most popular products sold in Ontario and other parts of the country. The company later expanded by opening two other production facilities in Oshawa and Montreal.
Each location consists of six departments: Production, Sales & Marketing, Accounting & Finance, HR, Administration, and Logistics.
In addition to the above departments, HQ has a unique IT department responsible for IT services for all locations. The IT manager is a BTM graduate from Ryerson. And here is the organizational chart for each location:
HQ: This facility consists of four floors: The first floor is the Production (100 employees) department. In second floor departments such as Sales & Marketing (20 employees), Accounting & Finance (20 employees), HR (10 employees), and Logistics (15 employees) are located.
The third floor is dedicated to offices for Joseph Hegelberg (President), Nina Hegelberg (Vice President), and six other senior managers: Production, Sales & Marketing, Accounting & Finance, HR, Logistics, and IT, including a big boardroom for meetings and video conferences.
The IT department (20 employees) occupies the entire fourth floor. This floor is the location of the main servers, DMZ, main network printing, and LAN/WAN connectivity devices. All floors are connected through a fiber optic backbone cable with a speed of 3Gb/s. Each floor is connected to the backbone cable through a high-speed switch in star topology fashion (IEEE 802.3).
The entire third floor is networked through wireless 802.11g technology using three access point devices connected to the backbone cable via a switch. All employees on this floor have their laptops and wireless printers.
Also, there are network-attached fax-copier-printer (combined) for floors 1-3. As mentioned above the IT department has the fasted and largest network-attached printer.
Except for the production and administration departments, each employee has his/her desktop computer. Note: the Admin people have their laptop computers which they carry every day to the work. Also, in the production area, there are 10 mobile wireless laptops connected via 802.11g for controlling the production lines.
XYZ-Bank is the main financial institution that processes all major transactions for Hegelberg Dairy Inc.
The Oshawa and Montreal facilities consist of two main floors (in each location), the first floor is production (40 employees) and the second floor is dedicated to offices for six other departments:
Sales & Marketing (8 employees), Accounting & Finance (8 employees), HR (4 employees), Logistics (5 employees), and administration (5 employees). The two floors for each location are connected through a fiber optic cable with a speed of 1Gb/s.
Each employee has his/her desktop computer. On each floor, there is a network-attached printer. In the production department, there are 5 mobile laptop computers (in each location: Oshawa and Montreal) for controlling the production lines. These WiFi laptops are connected through 802.11g.
6) Provide secure Web as well as email services to all employees, suppliers, and other stakeholders. Place these servers along with the other related servers (e.g., VPN server) in a DMZ area. Note: The DMZ is connected to the Internet through a firewall
7) There are five main LAN servers located in the IT department: A domain server (authentication server), a Database server, a File Server, an application server, and a Finance server. These servers provide services to all employees as well as managers in these locations.
You need to provide a secure solution for these servers. Use a graphical presentation for your solution and explain how these servers are secured.
