INTRODUCTION

When it comes to network devices and how they communicate with each other, we need to understand the type of devices and how they need to be configured within the network. We cannot form a network without communication devices and understanding their uses. To develop any type of network, communication devices are required and in this paper I will talk about three devices that are used within a network environment.

The first device I want to mention is a NIC Adapter. NIC stands for Network Interface Card, I consider this the most important network hardware when building your LAN (Local Area Network), WAN (Wide Area Network), or even MAN (Metro Area Network). This adapter is the most common part of the computer we use for our offices and homes. To call your office space a network, these cards need to be attached together with communication mediums (cables). Each card is assigned a unique MAC address that will identify the system it is in. Once you establish your LAN, then you can move on to connect with other LANs which will form a WAN or MAN, not only through the NIC Adapter but other network devices mentioned below.
This is where a Router comes into play. A router is an intelligent network device which transmits data to other destined computers. It connects two networks and like I said, it forwards packets between them according to the information in the packet header. This communication occurs at the network layer of the OSI model. Routing was initially performed by general purpose computers, but today they are typically performed by dedicated computers that are optimized for this purpose. They connect networks using various media and architectures.

Routers do not care about the type of data they have to handle, and they perform very little filtering of the data. There are different types of routers, but the most common are broadband and…...

...Devices on the Network Michael Gustafson NTC/405 10/8/2012 JOHN-HUNG HO Devices on the Network There have been many advances in the world of networking and there are a multitude of devices which are a part of any particular network. I will go over the following network devices: Network interface card (NIC), modems, network hubs, switches, routers, gateways, and repeaters. Also the difference between channels and circuits and the difference between circuit switching and packet switching will be addressed as well as the concept of Ohm’s law and its importance to circuit trouble shooting. A NIC or network interface card is a device which lets a piece of equipment interface with a network. A NIC is a card encoded with a special 48 bit unique number known as a MAC address which helps the network recognize the user so that it can access the network, a NIC supports a transfer up to 1000+ mbps. A transceiver is embedded in the NIC that can transfer media from the network to the NIC. A wireless NIC or WNIC is essentially the same as a wired NIC in that it too has a 48 bit address although the connection is through radio waves transmitted electronically from the NIC’s antennae. The connection is started electronically through antennae and transferred over radio waves then back into an electronic signal in the device. A modem is a piece of equipment used to connect a user’s computer to a network. The modem is essentially a converter in that it can convert analog cables to......

Network Access Control: User and Device Authentication

...Enterprise Security Network Access Control: User and Device Authentication August 2005 Intel IT is piloting new security methods to provide network access control by authenticating devices as well as users. Since networking has evolved to support both wired and wireless access, securing corporate networks from attack has become ever more essential. Therefore, to effectively enforce network access control policies in a proactive manner, we are developing a method to authenticate users and devices before they connect to the network. Network Access Control at Intel • Over 90,000 employees worldwide • 80 percent of knowledge workers are mobile and unwired • Over 50,000 remote access users Background As a global corporation, Intel IT supports more than 90,000 employees and contractors all over the world, and 80 percent of our knowledge workers are mobile and unwired. Network access depends more and more upon wireless LANs and WANs, as well as virtual private network (VPN) remote access. All of these technologies have the potential to open our network perimeter to threats. When we considered the threat of viruses and worms, it was evident that we needed additional controls to secure the enterprise network and its information assets from unauthorized devices and unauthorized people. Figure 1 shows how we could authenticate devices and users as part of the authentication pyramid. Figure 1. Authentication pyramid Info Use Auditing Access Control User Device......

... A Network Attached Storage device is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role. * What is the speed of the network adapter available on a NAS device? There are many varieties of NAS devices, depending on if you build it yourself or purchase it. The speed is usually 1GB Ethernet connection but it can be changed to multiple Gb, 10Gb, fiber optic by adding a PCIe network card(s). * What is the capacity range? The capacity range also varies. With a port replication and add on hardware drive controller cards there really isn’t a limit on size. A board that has six SATA ports can be replicated allowing for thirty drives to be attached, if 3TB drives are used in RAID 50,that would be 72TB of storage. * Is there any fault tolerance (such as RAID) built into a NAS device? If set up correctly RAID 50 is fairly stable, RAID 10 has been touted as on of the best set ups because more drives can fail at one time with having data loss. * Are management features available? Here are some management features available on a NAS device. ......

...Networks are hardware, software, and media that can be used to connect computers together allowing them to communicate, exchange information and share resources. Networks allow multiple users to access shared data and programs. There are five kinds of networks; LAN, WAN, CAN, MAN, and HAN. The two main types of networks are LAN and WAN. LAN stands for local area network, and WAN stands for wide area network. According to our text “A local area network (LAN) is a data communication system consisting of several devices such as computers and printers.” (The McGraw−Hill Companies, 2006). These devices are physically connected to one another by cables, wireless media, or infrared links. Any network within a building or several that are next to each other is a LAN. A WAN, also known as a wide area network is made up of two or more LAN’s geographically connected. An example of a WAN is when a company or business located in one place has its main offices in one place and other smaller parts of the company in other places all data is shared within the network. There are also three types of hybrid networks, CAN’s, MAN’s, and HAN’s. A CAN or campus area network is like a LAN but on a bigger scale and more diversified, allowing different campus offices and organizations to be linked. For example, at a college the registrar’s office is connected to the bursar’s office. MAN’s which are metropolitan area networks are a large type of network that connects many corporate LANs together.......

...Computing technology advances in the past decade have created a more easy and flexible work place. Mobile technology can mean greater productivity, but it also has inadequate security measures to mitigate the risks inherent in the use of mobile devices. There are many factors to consider when deciding if wireless networking or in specifically if wireless technology is a reliable and safe route for the healthcare systems. Given the type of wireless infrastructure and different construction techniques, there are many ways to develop safe, reliable and most importantly a secure wireless health care technology. First, the important thing to consider is the assurance and security that we may face in today's enterprise healthcare systems. For this particular case, there are multiple office spaces in the professional building. With that said there may be multiple wireless transmitters and due to a radio-frequency wireless application may be a source of interference for another application. Security for wireless medical devices and systems must be addressed and make sure that it is able to handle such risks that can be involved. Some things to keep in mind would be if this exchangeability is worth the risks with such diligent information. With these interferences, it's a matter of manageability for a safe and secure method of transferring patient data from one space to another. Secondly, threats differ by groups whether they may be a police force or a medical team and most......

...Mobile Devices Now days, wireless communication and devices are very flexible, convenient, and easy to use everywhere. With the introduction of wireless local area network (WLAN) many users find it very flexible to move laptops from one place to another within the office while maintaining connectivity with the network, sharing data and applications with network system and other users with compatible devices without been tied to printer cables and other peripheral device connection. This is very important in a doctor’s office because patients and doctors move from room to room depends on the type of test they are doing. Having mobile device makes it easier for them to do their jobs easier and it can even help cut wiring costs (Patricia & Donna, 2008). In the other hand there are many risks inherent in using wireless and mobile technologies. Wireless networks face the same threats as conventional wired network because intruders who gain access to information systems via wireless communication can bypass firewall protection and expose patient’s information and data. Besides lunching denial of service attacks, insert viruses or malicious code, disable operations, most importantly they can violate the privacy of patients and even steal their identities.  Risk of using wireless or mobile technology makes it easier to come up with a plan is place to try preventing further actions. This open connectivity brings with it risks, however, some of which are similar to those in......

...Network Attached Device Network-attached storage (NAS) is a dedicated hard disk storage device that is set up with its own network address and provides file-based data storage services to other devices on the network. It is attached to a local area network and assigned an IP address, allowing both application programming and files to be served faster because they are not competing for processor resources. NAS devices are usually configured with a web browser and do not have a keyboard or display. Consists of hard disk storage, including multi-disk RAID systems and can usually handle a number of network protocols, including Microsoft's Internetwork Packet Exchange and NetBEUI, Novell's Netware Internetwork Packet Exchange, and Sun Microsystems' Network File System. (Rouse, 2013) NAS devices speed is typically one gigabit Ethernet connection but this can be changed to multiple gigabit, 10 gigabit, fiber optic by adding a pci-e network card(s). Older parts can be used which may be limited to 10/100 megabit. If you need an exact answer for speed, simply look at the wiki on gigabit. The capacity range varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and add on hard drive controller cards there is hardly a limit on size. A board with 6 SATA ports can be replicated (1 to 5 port) allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage.

Network Endpoints and Network Devices Have Different Security Considerations and Implications

...NT2580: Week 2 Explore the Importance of Security Policies Analysis 2.1 Testing and Monitoring Security Controls Network endpoints and network devices have different security considerations and implications. A user workstation implies certain security issues that remain in the user domain while network implications remain part of the LAN or LAN-to-WAN domain. However, during the course of investigating an intrusion, you may have to source data from logs kept in routing devices and end-user systems. Suppose an attacker intrudes upon one of your servers. How do you reconstruct the events of a crime? Log files are the first place to check for administrative issues and security activity. Log files help you put together a timeline of events surrounding everything from a performance problem to a security incident. You can also identify bad system or network activities by observing anomalies from baseline behavior or identifying certain suspicious actions. Testing ensures that your control and monitoring facilities work as intended and maintain proper operation. Monitoring ensures that you capture evidence when your testing procedures fail to examine all possibilities or legitimate behavior permits unauthorized activity. Always consider that even legitimate traffic can be used in illegitimate ways, and sometimes, legitimate traffic can appear illegitimate. Protected services can be attacked from the inside or accessed externally through loopholes in firewall rules.......

...2.1.1 Network History The history of computer networking is complex. It has involved many people from all over the world over the past 35 years. Presented here is a simplified view of how the Internet evolved. The processes of invention and commercialization are far more complicated, but it is helpful to look at the fundamental development. In the 1940s computers were large electromechanical devices that were prone to failure. In 1947 the invention of a semiconductor transistor opened up many possibilities for making smaller, more reliable computers. In the 1950s mainframe computers, which were run by punched card programs, began to be used by large institutions. In the late 1950s the integrated circuit that combined several, then many, and now millions, of transistors on one small piece of semiconductor was invented. Through the 1960s mainframes with terminals were commonplace, and integrated circuits were widely used. In the late 1960s and 1970s, smaller computers, called minicomputers came into existence. However, these minicomputers were still very large by modern standards. In 1977 the Apple Computer Company introduced the microcomputer, also known as the personal computer. In 1981 IBM introduced its first personal computer. The user-friendly Mac, the open-architecture IBM PC, and the further micro-miniaturization of integrated circuits led to widespread use of personal computers in homes and businesses. In the mid-1980s users with stand-alone......

Protecting Wireless Devices and Enhancing Security in a Wireless Network

...Wii, Netbooks, iPods, etc…) like wireless devices, there are many advantages and disadvantages in operating wirelessly. No matter how you feel about the advantages or disadvantages of the devices, they need to be protected, along with setting up some form of security. On the website Howstufworksvideo (12) they show you the basics on how to setup home Network Security. You can go there can see how it is done. Just a few years ago, (25 Sep 07) there were some so-called experts saying that there was no need to secure your wireless system. In an article, David Ramel alleges that the importance of wireless security is overhyped, that it's now trivial to secure wireless nets and that IT pros have far more serious security concerns they should be addressing -- while home users have little to lose even in the remote chance someone tries to breach their network.
