Integrative Network Design Project The redesign for Kudler Fine Foods has covered the topology and standards and has defined the architecture, protocols, and strategies it will employ. Now security is the issue that needs to be reviewed. The most important aspect of any communications platform is that it is secure. This paper will discuss the security of the network and the details of the hardware choices that will be used in it.
Security Hardware and Software Between every network and the outside host of threats there is a first line of defense. For almost every network this will be a firewall. A firewall can be both hardware and software and is usually a combination of the two. A firewall creates a barrier between networks. Any outside computer or client must pass through the firewall to access the network or its resources. Only a computer or system that has proper access can easily access a network protected by a properly configured firewall. Though it is not infallible, a firewall is the first and perhaps best means of security …show more content…
A local network can mean a small network in a home, or a business network covering several buildings on a city block. LANs are relatively fast, compact, and when configured correctly, have few errors or problems. The hardware needed to build an LAN is set up on OSI levels 1 and 2 and include devices like switches, bridges, hubs, and repeaters. Wide area networks (WAN) are complex networks that span large geographical areas. The most commonly known WAN is the Internet. WANs tend to be slower in speed, highly complex, and intolerant of system problems. Because of the multitude of connections on a WAN, even a simple down can create problems across the network.
