Part 1 (paid an extra page for this) Use Microsoft Visio or an open-source alternative to: Create a network infrastructure diagram, incorporating the following devices needed for a secure corporate network, placed where they will work, and citing specific, credible sources that support the design. Note: A web search will provide multiple examples of network infrastructure diagrams. Web server. FTP server. VPN server. Authentication server. Anti-virus server (client-based and server-based). Edge firewall. Firewall. Vulnerability scanner. Intrusion detection system (IDS). Web proxy. Edge router. Core router. Switch. Distribution router. Note: All client- and server-based devices work where a client is installed on a workstation, which has bi-directional communication with a corresponding server. Part 2 Write a 5 page paper in which you: Determine the specific devices you will use in the network, including the following information for each device: Make or vendor’s name (for example, Microsoft, Redhat, Cisco, Juniper, Netgear, 3Com). Model (for example, Windows 7, ASA 5500, Cisco 3500, Squid). IP address assigned to all devices. Determine the basic configuration of each network device, citing specific, credible sources that support the configuration. Research each of the devices you chose and provide a basic configuration you would use in your network. Use IP addresses to describe your configuration. Identify the operating system. Highlight at least five security features and the administrative controls incorporated into each device, including devices in the network diagram. Explain the impact that each of your configurations has on the security of the entire network. Explain the elements that must be addressed for planning and testing a network, citing specific, credible sources that support your assertions and conclusions. Organizational requirements and expectations. Budget. Modularity for security and testing. Naming conventions that facilitate layering and growth. Determination of required network speed and data capacity. Vendor support. Determination of risk and redundancy.
