...Network Design Student Name Course 2 July 2014 Professor Identify hardware and software needed to secure your choice of networks against all electronic threats. A network that helps a workstation to connect with each other is called a Networking hardware. If a company uses both routers and firewall, the company is assured protection of both wireless and cabled networks that are used in the company. Network hardware is suitable in any organization in the keeping of the organizations network safe. In the software part I will choose to use McAfee Anti-virus security software. This software in conjunction with firewall is a sure way of protecting a company. Routers when used along with hardware are the best security hardware needed if the company needs to increase the security of their network to a level where none of the intruders can be able to access it (Radu, 2002). The function of the firewall in an organization is to ensure that all unwanted activities are blocked including hackers that can retrieve important and delicate information of the company. Hacking will be a very dangerous exercise where criminal can access the important information that a company has and use this information in blackmailing the company and its customers. Networking software’s also plays a major role in securing an organizations network security. The software has the capabilities of detecting viruses that may attack an organization and make an organization loose its critical...

Kudler Fine Foods new network will have multiple hardware choices to make. Each location has Point of Sale (POS) computers that need to be secured from attack; there are office computers that will need to be secure. The POS server will need to be secured as well. There is the wireless Ethernet switch that will connect to the modem and Wide Area Network (WAN) between the three stores. The central hub location for the WAN (the Del Mar store) will also need to make sure the data servers are secured as well as everything else already mentioned. The desktop computers are going to be up to personal preference for Kudler Fine Foods, most desktops are just about the same weather they come from the big companies like Dell and HP. Each location will have two office desktop computers as well as four POS computers, a Standalone UPS in case of power outage.

...Local Area and Wide Area Networks The complex nature of today’s local and wide area networks requires a great deal of planning before the network can be assembled and configured. Identifying and implementing network security is a key area of concern due to the large variety of network vulnerabilities that can be exploited by both malicious and external users. Additionally, the correct switching and routing technologies must be implemented to ensure the efficiency and availability of the network. A network can reach its peak security and efficiency only when these factors are fully considered and correctly configured in the network. Security Hardware and Software One of the primary concerns in the development of a network is introducing and configuring the proper security hardware and software. One of the primary tools in ensuring the security of a modern network is the implementation of a network firewall. A network firewall is designed to allow or deny packets entry or exit to the network based on user defined rules (Beal, n.d.). Traffic can be allowed or denied entry to the network based on a variety of criteria. Traffic can be inspected and allowed, based on IP, port number, application, or its entry or exit security level (Beal, n.d.). For these reasons the internal network will be guarded by the Cisco ASA 5512-X Firewall. The ASA 5512 firewall provides up to 1Gbps throughput with stateful packet inspection with is sufficient to support the maximum speed of the networks...

...AT&T Corporation AT&T AT&T is one of the most popular companies that provide variety of services; voice, data, and communications and is the largest provider for mobile telephony and fixed telephony. There is a main server called the proxy server which AT&T uses, which acts as a server and a client in making request on behalf of other clients, it can provide routing and can enforce policy. The proxy server is an application layer service that routes SIP request and replies; it hides the identities of endpoint and it may be redundant because its functions overlap with those of the firewall proxy service. Proxy servers are rarely implemented in SIP networks because of the cost, delay, delay variation, and complexity they add to the service. The next server would be a redirect server; which makes mobile and nomadic users reachable as well as users who have new phone numbers it is a part of the availability service as well as geographic location services provided by the location server. The type of switches this company uses is the Cisco switches they are used to create a network by connecting and controlling all of your organizations computers, printers, and servers and it can also increase efficiency, productivity, and allow your devices to talk to one another through information sharing and resource allocation. Cisco offers two types of network switches: * Cisco unmanaged switches, which are found in home networks work right out of the box and are not designed to be...

...Data Communication Theory What is dotted decimal notation on IPv4 addresses? Answer: It is presentation form for the numerical data that consists of a string of decimal numbers each pair is separated by a dot. The common use is to write the numbers in the octet group based 10 (decimal) numbers separated by dots. In computer networking, Internet Protocol Version 4 addresses are commonly written using quad-dotted notation of four decimal integers, ranging from 0 to 255 each. Chapter 6- Explain the Peer-to Peer network and what are its advantages? Answer – In Peer to Peer network, network hosts don’t have a specific role. They provide specific services and also consume network services. We have hosts that will fulfill a variety of different roles, like one computer can have printer connected to it which is then shared on to the network. Another computer can have a large hard drive attached to it and everyone else is allowed to use the hard drive for data storage, modification etc. In Such network we have hosts that both provide and consume network services. In essence they function both as a Client and as a Server at the same time. The advantage of Peer to Peer network is the ease of installation. We can share our resources on the network and everyone can share the benefits. On the other hand is not very scalable. The Peer-to-peer network are useful only for a network with fewer computers and are suitable for applications that do not require a high level of...

...Routers Term Paper INTRODUCTION Router is a hardware device designed to take incoming packets, analyzing the packets and then directing them to the appropriate locations, moving the packets to another network, converting the packets to be moved across a different network interface, dropping the packets, or performing any other number of other actions. In the picture to the down, is a Linksys BEFSR11 router and is what most home routers look like. [pic] A router has a lot more capabilities than other network devices such as a hub or a switch that are only able to perform basic network functions. For example, a hub is often used to transfer data between computers or network devices, but does not analyze or do anything with the data it is transferring. Routers however can analyze the data being sent over a network, change how it is packaged and send it to another network or over a different network. For example, routers are commonly used in home networks to share a single Internet connection with multiple computers. [pic] In the above example of a home network there are two different examples of a router, the router and the wireless router. As can be seen in the example the router is what allows all the computers and other network devices access the Internet. Below are some additional examples of different types of routers used in a large network. Brouter Short for Bridge Router, a "brouter" is a networking...

...well as networking devices (eg. Switches/hubs). Select the appropriate network media to use. The network media necessary for this is as follows: Switch x11 – For each room that requires more than one computer and the server rooms. The reason for this is so that ports can be allocated accordingly to staff or students as well. Patch Panel x11 – For each room that has a switch so that multiple computers can access the ports on the switch. The patch panel will provide the network with a connection point between network equipment and the ports to which the PCs are connected. Router x1 – This is where the default gateway for the network will be and is located at the demarcation point. It is used to route information obtained by the network and deliver packets returned by the Internet.

...Wireless Router Configuration- Gateway Configuration Cisco Linksys Products (http://homesupport.cisco.com/en-us/wireless/lbc/WRT54G) Model # WRT54G Firmware : v1.4 – v 4.20. Barry Rodricks Outline Introduction. Configuring the Router as a Gateway. References Introduction What is a default Gateway ? A default gateway is the device that passes traffic from the local subnet to devices on other subnets. The default gateway often connects a local network to the Internet, although internal gateways for local networks also exist. In simple words the Gateway (normally associated with a router ) is an entry and an exit point for network traffic. A depiction below shows a SOHO and how the wireless router acts as a gateway for all the devices connected. In big enterprises, the device playing the part of a gateway could also act as a proxy server and a firewall. In most cases the gateway is a router, which use headers and forwarding tables to determine where packets are sent. Configuring the Router as a Gateway Login to the router’s web interface (refer to router guide) , and click on the “Setup Tab” and proceed to the “Advanced Routing option” Use the instructions as given below : If the Router is directly connected to the DSL/Cable modem, select the default option of Gateway. In this example , we will attempt to configure the router as a gateway . Our assumption would be that the customer only has one wireless router connecting to the Cable/DSL...
