In this assignment, you are going to design a simple network monitoring system that is suitable for a small business. 
Project Background: 

You are the proprietor of InSat a new Internet based startup that focuses satire on the American political process. Your first real product is a tee shirt that portrays Andrew Jackson and Martin Van Buren as Batman and Robin. You are operating your entire company out of your parents' two car garage; on one side you silkscreen the tee shirts and on the other side you have your computers.

Your entire network consists of three nodes, a Linksys EA 3500 wireless router, and a dumb gigabit Ethernet switch. All three nodes are directly connected to the switch, and the switch is in turn connected to one of the LAN ports of the router; the other three LAN ports on the router are vacant. Your nodes are a mixture of two Windows 7 nodes and one CentOS Linux node. Your Linksys router is directly connected to a cable modem which in turn has a connection to the Internet through a cable provider's Business Class services for small business.

You have contracted with your cable provider for a single static IP address. You have used the DMZ Host feature of your router to redirect unsolicited inbound traffic directly to the CentOS Linux node. You are using the CentOS Linux node to host an Apache web server that advertises your business. You are allowing only unsolicited inbound SSH, HTTP and HTTPS traffic from the Internet through your router. And, as an extra precaution, you are only accepting unsolicited inbound SSH traffic on port 36415 instead of the standard port 22.

You must design a simple network monitoring system that is suitable for a small business. You must secure your network and establish the network monitoring system. You have no money to spend, so your solutions must require no cost whatsoever. A no cost solution is a firm requirement. You have been advised to document your network to show potential investors that you are serious.
Project Requirements: 

You must create a presentation in .ppt or .pptx format with no less than 6 slides that describes the challenges of monitoring a simple LAN when there is no money available to purchase resources. Your presentation must identify a no cost solution that you will use to perform basic network monitoring. Your presentation must describe the methods and procedures that will be used to monitor and secure the small LAN.
You are required to list all of the components that are present in your network, to describe which components must be monitored, and to identify the security requirements of each monitored component. You must produce a network diagram that describes your network. The network diagram must be included in your presentation. You must include in your presentation any other information that is necessary to describe the monitoring system that you are using.
