Abstract
This guide helps you implement Domain Name System (DNS) on the Windows Server® 2008 operating system in a small network. Windows Server 2008 uses DNS to translate computer names to network addresses. An Active Directory® domain controller can act as a DNS server that registers the names and addresses of computers in the domain and then provides the network address of a member computer when the domain controller receives a query with the name of the computer. This guide explains how to set up DNS on a simple network that consists of a single domain.

Domain Name System (DNS) is a system for naming computers and network services that maps those names to network addresses and organizes them into a hierarchy of domains. DNS naming is used on TCP/IP networks, such as the Internet and most corporate networks, to locate computers and services by using user-friendly names. When a user enters the DNS name of a computer in an application, DNS can look up the name and provide other information that is associated with the computer, such as its IP address or services that it provides for the network. This process is called name resolution.
Name systems, such as DNS, make it easier to use network resources by providing users with a way

Kudler Fine Foods Network Design Project

...INDP Final Kudler Fine Foods Network Design Project NTC 362 March 17, 2014 Introduction This paper will present the Final Integrative Network Design outlining the cumulative plan that Kudler Fine Foods has accepted and agreed on for implementation of the following: Final Network Design The integrative network design project for Kudler Fine Foods will include Transmission Control Protocol/ Internet Protocol (TCP/IP) will be used as a means of communication within a private network or the internet for Kudler Fine Foods network devices. Hypertext Transfer Protocol (HTTP) is used for transfer of multimedia files, video, sound, and text over the internet. Kudler Fine Foods will implement File Transfer Protocol (FTP) to download files, transfer files, delete files, copy and rename files from the internet as needed. Mesh Protocol will be used to connect all devices such as printers, computers, and scanners on the network. In a true mesh topology every node has a connection to every other node in the network ("Common Physical Network Topologies ", 2014).   The network will consist of a hardware firewall blocking unwanted access from outside of the location. The next step is to set up a hub or switch that will connect all of the stores terminals. All of these terminals such as registers and remote locations such as warehouse will be hardwired with twisted pair CAT 5 Ethernet cable. The server will be located in a room in each store with the hub or switch. A wireless...

Foundations of Network Security Fundamentals of Network Security 2 Firewall Fundamentals 43 VPN Fundamentals 79 Network Security Threats and Issues 111 CHAPTer Fundamentals of Network Security 1 C OMPUTER NETWORK SECURITY is very complex. New threats from inside and outside networks appear constantly. Just as constantly, the security community is always developing new products and procedures to defend against threats of the past and unknowns of the future. As companies merge, people lose their jobs, new equipment comes on line, and business tasks change, people do not always do what we expect. Network security configurations that worked well yesterday, might not work quite as well tomorrow. In an ever-changing business climate, whom should you trust? Has your trust been violated? How would you even know? Who is attempting to harm your network this time? Because of these complex issues, you need to understand the essentials of network security. This chapter will introduce you to the basic elements of network security. Once you have a firm grasp of these fundamentals, you will be well equipped to put effective security measures into practice on your organization’s network. While this textbook focuses on general network security, including firewalls and virtual private networks (VPNs), many of the important basics of network security are introduced in this chapter.
