Network Management and System Administration

The aim of the paper is to establish the difference between a system administrator and a network administrator. The paper is thus divided into three sections. The first section deals with the basic definition and responsibilities of a system administrator; the second does the same for a network administrator and the third compares their responsibilities to clearly identify the differences between the two.

System Administrator

The maintenance of computer systems in a company is the sole responsibility of a system administrator. They are responsible for maintaining, upgrading and installing servers. They are also entrusted with the task of checking the security of the server and maintaining its backup as well. They are also involved in programming for automating tasks at the server. For this purpose, they write programs, also known as scripting (Schneider, 2012a).

In some areas it will be used for more populist applications such as, in schools to introduce students to the discipline and within an environment that will give opportunity for participation of non-academics in academic discussion.

Conclusion

Computer has in a great deal widened the world's knowledge. As the fastest technology that has ever evolved, it has given opportunity for the children and adults, for personal, academic and commercial use. It has made communication to be easier; people get to know what is happening in the other parts of the world instantly. Information and data entering and saving has been made convenient and even easy.

Evaluating the Advantages and Disadvantages

of Using Cloud-Based Systems for IT Storage and Applications

The emergence of cloud computing as a disruptive innovation is redefining the economics of information technologies, application delivery and the pace of new feature development and introduction. Companies who are standardizing on cloud computing for critical tasks including Customer elationship Management (CM) do so after evaluating several factors, including the opportunity to expense the costs vs. pay for them via capital expense, the customization of the applications, and the ability to selectively update them over time (Lashar, 2009). Cloud-based applications delivered over Software-as-a-Service (SaaS) platforms are paid for as an operating expense, which is often referred to as OPEX. Traditional enterprise software is paid for through CAPEX, or capital expense investment. This is a critical point in the economics of this market and a primary criterion that TUI University needs to consider was it…

Network Vulnerabilities and Controls

Computer networks are constantly under threat from many different sources of attacks. In order to get a clear understanding of the different views on computer security and its characteristics, it is important to define a network. This term means a group of computers that have been interconnected to communicate to one another using electrical signals. The network can be either wired or wireless and the most common of them nowadays is the wireless computer network. The internet or wide area network can link very many computers that are widely and geographically apart.

Computers are therefore linked to communicate with one another via the internet. However, these same computers are prone to attacks from all different angles. Any unauthorized access to ones computer can be defined as an attack since in the process, valuable information may be retrieved from the computer or even deleted. The information may…

Network Standards

A Brief Look Since 1995

This is a research paper that focuses on network standards and protocols that involve strategies in management. Leadership strategies cannot handle the need for network standards to handle billions of users and user generated applications. Therefore management strategies are more appropriate. Furthermore the history of network standards shows layering through the OSI models follows a management approach vs. A leadership approach.

In the OSI model, there are seven layers. The seven layers then acts as a means of managing problems within that layer as it is separated and contained. People can run communication through these layers much more easily and smoothly than through a singular, whole layer. The several layers are more efficient and can handle and spot problems and inefficiencies more quickly. It serves as the basis for network standards.

The history behind network standards provides valuable insight into how organizations emerged…

All network authorized personnel must be instructed to use "strong" passwords consisting of at least 8 characters; they must include at least one upper and one lower case letter, at least one Arabic number, and at least one "special character" in addition to avoiding any form or abbreviation of the user's first or last name (Boyce, 2002; Kizza, 2005).

Network administrators must also implement applications capable of ensuring compliance by automatically rejecting improper password choices. Additionally, administrators must require authorized users to change their passwords at specific intervals. Finally, office managers must monitor compliance with common-sense rules about behavioral aspects of password security, such as prohibiting divulging passwords to co-workers, requiring users to log off if they leave their terminals, and by providing training into recognizing attempted social engineering to obtain secure information through deception (Larson, 2007).

Likewise, authentication layers can also significantly enhance network security. In that regard, the…

). Such security should also preplan strategic responses to attacks associated with the network (Dawkins et al.).

A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained between the firewall and the internet access or between the firewall and the internal network are often vulnerable. Organizations with networks should work hard to secure them at these points. The article also states that if attackers can gain access to a network at these points, they can gain access to sensitive information and compromise the stability of the network. Also attackers who gain access to a network at one of the aforementioned points will also be able to…

Network Security: Past, Present and Future

The work of Curtin (2007) states that a network is defined as "any set of interlinking lines resembling a net, a network of roads -- an interconnected system, a network of alliances." Quite simply a computer network is a system of computers that are interconnected. There are seven layers of communication types identified by the International Standards Organization (ISO) Open Systems Interconnect (OSI) eference Model as well as the interfaces among them. Each layer is stated to be dependent on the services that the layer above it provides including the physical network hardware.

Technology: Description and Area of esearch

Attempts to alleviate or at least reduce network congestion including using un length Encoding (LL) for packet size reduction, the use of abbreviated headers for optimizing their path through networks, and the development of protocols that seek to optimize path selection through a network (Wen, Wang, Yang, 2007). The challenge of continually enhancing and increasing network performance through better optimization of paths throughout a network is being made more challenging with the en masse adoption of WiFi as well (Wen, Wang, Yang, 2007).

Computers are tools for learning; and as such are not essentially different from the way dictionaries, calculators, and videos are teaching and learning tools. However, computers provide a wide range of learning experiences that do make them qualitatively and quantitatively different from other learning tools. Three ways that computers measurably benefit the learning experience include communication, information access and retrieval, and training. Computers facilitate communication between learner and teacher, or between learner and peers. With computers and their applications, the raw data of learning -- that is, information -- becomes accessible to both teacher and learners. Training manuals and tutorials can be digitalized in ways that are accessible to learners regardless of geography and time. In spite of these three benefits of computers as learning tools, there are three detriments to the use of information technology in the higher education classroom. One detriment is the digital divide, or income disparity…

Network Design

The process of gathering technical requirements for a network design project may differ from one organization to another, but the requirements themselves can be described using many of the concepts discussed in the lecture this week (i.e. Scalability, Availability, Network performance, Security, Manageability, and Affordability).

Analyzing technical requirements for the customer is important in helping one best fulfill the customer's expectations. The various objectives that need to be fulfilled involve the factors of Scalability, Availability, Network performance, Security, Manageability, and Affordability.

Scalability

Scalability refers to the amount of growth that a network design can support. This is particularly important for large companies that are adding users, applications, additional sites, and external network connections all the time. The proposed network deign should be able to adapt to any envisioned additions. You will want to know the prospective amount of networks, users, servers, and/or sites that may be added to…

Prioritizing the goals is helpful for both you and client, so you start off with the most important goal ending with that least important to client. A list of options, too, can be made and correlated with goals. In this way, you will be more likely to design a computer network that will meet client's expectations.

Wireless and Wi-Fi

The dominant approach used today for connecting to network, wireless technologies including W-Fi is dominating the entire area of networking, from 3G and 4G on smartphones and tablet PCs to the development of hotspot technology on the attest iPad. This is the future of networking for many consumers. The reliance on Wi-Fi as a means to stay connected to business and friends has exponentially increased and will continue to for the long-term (Gilmer, 2010). The fundamentals of Wi-Fi are easily taught as they are based on IEEE standards that create a framework for teaching these technologies with clarity and insight (Greiner, 2001). Wi-Fi continues to increase in terms of speed as well, with 3G and 4G now commonplace. Consumers need to know about this technology and how it works to troubleshoot problems on their smartphones, tablet PCs and laptops. The best approach to managing the teaching process…

Network Security Administrator, Approach Problem Securing a Central

I would utilize a number of security measures to adequately secure a central computer network that is accessed by other branches and staff from remote physical location. The vast majority tends to work in conjunction with one another, and should not deny access to authorized users.

For all of the computers that are present in the primary, physical location in which the network is based out of, I would employ encryption measures. This sort of encryption is similar to that used by cellular devices (whether in the form of tablets or phones), which enables users to reduce the threat of unauthorized users from accessing their devices or the data within them (Stafford, 2010). However, it is worth noting that encryption would not be used on the computing devices in the network that are outside of this primary physical location.

What are the advantages of computers in communication? In education? In entertainment? In the economy? What are the disadvantages in these areas? Is computer technology creating winners and losers, or furthering social stratification? Have we become too dependent on computers? Do computers limit social skills and physical activity to a damaging degree? Why or why not? Computers have changed our national culture and our global culture, and not always for the better. When they were first developed for the mass market, computers were meant to increase productivity and cut down on paper work.

In addition, The potential for IPv6 to significantly reduce the overall costs of supporting an enterprise-wide network are also very clear as well.

ATM portals and technologies are ideal for creating a unified computing and networking platform corporate-wide, especially if a company has operations in several countries, and across continents. The speed and bandwidth considerations of running a global enterprise are also accentuated by this technology, as is a drastic reduction in Total Cost of Ownership (TCO) for a given network topology that must scale to be global. In addition, ATM could be used for unifying diverse legacy systems into a single, cohesive network architecture that capitalizes on the many information assets a company has (Dunne, Klementowski, 1982). In addition, these networks also make it possible to create entirely new approaches to solving very complex problems in enterprise, including the ability to collaborate and produce new product designs in real-time…

After server authorization four domains for giving and registration of addresses of clients are created. "If a physical LAN has more than one logical subnet, how can different groups of clients be allocated addresses on different subnets?

One way to do this is to preconfigure each client with information about what group it belongs to. A DHCP feature designed for this is the user class option. To do this, the client software must allow the user class option to be preconfigured and the server software must support its use to control which pool a client's address is allocated from.

Knowledge of e-crime from the perspective of crime science is insufficient in devolution of the problem, which cuts across various sections of social interaction through computers. There is a limitation in the forensic and social / legal exploration of information technology aspects and that is the possible cause of the limitations of the jurisdictions of the computer crime legislation, creating the insufficiency in the fulfillment of its purpose (Tonry 2009 p. 20-350).

The legislation approaches the infringement of the social precepts of technology without any consideration of social remedies. The use of police in regulation of operations is limiting because they may not have the capacity for gauging the extent of computer damage. It is logical considering the sensitivity of pro-social individuals, and their possibility of taking up their responsibilities. Social norms revolve around consideration of others and create a sense of mindfulness and consideration of activities (Humphreys 2007 p.…

computer used by the employee has either been compromised physically with a password cracking software (EC-Council,2010;Beaver & McClure,2010) or it has bee compromised remotely with the help of a keylogging software.A keylogger is noted by APWG (2006) as a special crimeware code that is designed with the sole intention of collecting information from the end-user terminal. The stolen information includes every strike of the keyboard which it captures.The most sensitive of the captured information are the user's credentials. Keylogger may also be used to refer to the hardware used for this purpose. The employee's password could also have been shoulder-surfed by his immediate neighbor at the workplace. This could be his coworker who manages to peek and see over his shoulder as he types in sensitive authentication information (password)

New Computer System for the 21st Century Business Office

It is impossible to imagine that any business can be run in the 21st century without an adequate computer system. And yet therein lies the rub: Determining what computer system is adequate for any business purpose is in fact a complex and difficult process in many cases. All too often what happens when a manager is faced with choosing a new computer system (usually at the point when the old one has completely crashed, losing valuable information that wasn't backed-up) is that he or she finds the brochure that's on the top of the pile and orders that computer system.

But this is not the way to proceed. Acquiring the right information system is essential in keeping a company healthy. This paper examines a real-world case of a corporation - in this case, Toys Us - adopted a new computer information…

Computer mediated Communication (CMC)

Throughout the years, people used different means of communication to pass information from one source to another. The type of communication involved face-to-face, writing letters then sending to people, using telegrams which was the quickest means of communication, and use of telephones, although telephones were invented some years back. Today, the world has become computerized and there are new technologies that most firms have acquired to ease communication as well as replace labor. The computer mediated communications (CMC) that emerged involved the use of e-mail, chat rooms, and Usenet groups. In summary, this paper gives a narrative regarding the issue of Computer Mediated Communication as well as, analyzing the linguistic and visual features of my topic while explaining how they affect communication.

Selecting the type of cable to be used when developing a LAN from the ground up can be a complex process with many considerations, including issues of functionality and of cost. Twisted pair cables provide a cheaper alternative to other cable types and are also the most flexible type of cable, but they are less secure and are more prone to losses in data integrity than are other standard cable types (Hsieh, 2012). Fiber optic cables provide the best protection against interference and are the most secure cable for use in a network, but the cost can be prohibitive and the heightened performance aspects are not necessary in all applications (Hsieh, 2012). Coaxial cables come in two varieties, thinnet and thicknet, with thinnet being both cheaper and more flexible than twisted pair cables (though still more expensive and less flexible) and also provide a decent amount of security…

This is what creates the continual need to share literally everything going on in their lives, as each post releases a significant dopamine rush (Charman-Anderson, 17, 18).

Dopamine is also the reason why the many forms of computer addiction are so difficult to treat. ith anonymity comes the opportunity to create multiple identities or personas online (Soule, 66, 67). This is what leads employees who have Internet addictions to create many different online identities, giving them ethical and moral leeway they would never give themselves. This aspect of personas and the forgiven unethicacy of conduct of personas is a key factor in online crimes committed by employees during company hours (Nykodym, Ariss, Kurtz, 82, 83). The personas of the addicted computer addicts are orchestrated for specific dopamine-driven production to fuel and feed habitual behaviors online

Computer History Museum: A virtual visit

Description of the event

The Computer History Museum has both an online and a 'real world' incarnation. It is a physical warehouse of different types of computers, a virtual catalogue of computer history throughout the ages, and also provides information about specific topics pertinent to computer history, such as the history of video games. The Museum contains artifacts such as the first calculators, 'punch cards' and online computers as well as information about their place in computer history. It makes a convincing case about the ubiquity of computers in everyday life from an early age, even though the contrast between the primitive nature of early computers and computers today is striking.

There is also a stark contrast between the functionality of early computers and computers today. The computers we use on a daily basis are multifunctional. People demand that their smartphones do everything from…

Network Security: An Issue for Business Data Communication

Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time.

The key security issue facing IT professionals is to protect the system from invaders or intruders known as Hackers. Hackers can be grouped into several categories according to motive. They are Joyriders (who do it for fun), Vandals (who do it to cause harm),…

The behavior of both botnets and worms in peer-to-peer networks have been empirically examined and models or simulations of their behavior have been attempted, and the manner in which different nodes in peer-to-peer networks develop in and of themselves and in terms of their relationships with other nodes -- the very architecture of the network itself, in other words, which is necessarily dynamic in a peer-to-peer network -- makes it easier for these threats to spread and evolve undetected due to this architecture and to the patterns of information flow over such networks (Fan, 2011; Xu et al., 2011). When it comes to worms propagating in peer-to-eer networks, the activity of the worm itself has been demonstrated to be the most necessary knowledge in terms of tracking and preventing the continued spread and damage of such a threat, while botnets generally show more "robustness" an are better impacted by shifts…

Network Design Consultation

Design recommended for the client

The requirement of the client of the small billing business shall deserve a tailored system for his network design. This compels for network similar for a small office management process. Shall has a variety of the components suited in their places. The network shall facilitate the process of file sharing, internet access, connection to a networked printer, maintain a basic, secure environment and facilitate a multiple email addresses. The application of the client/server system shall prove vital for the entire process of the design work considering the laid requirement by the clients. The client specifies that the numbers of the user are three. This leads to the categorization as the multiple user networks (Kennington, 2011).

Conclusion

The purpose of this discussion was to examine the network security measures that are available. The research found that the proper configuration provides the first line of defense as it relates to securing a network.

In addition, firewalls serve an essential role in securing networks against outside intrusions. The research also indicates that anti-virus software, encryption software and biometrics allow organizations to secure networks in a more comprehensive manner. There are also specific strategies and technologies that should be considered if an organization chooses to use a wireless network.

To some users of personal computers, who state, never trust a computer that you cannot lift; the IBM has been viewed, more often than not, as an enemy, and according to Byte, the computer magazine, this was because of the fact that the IBM company rose to fame mainly on the basis of its mainframe computers, that were large and forbidding, and overwhelmingly bulky. This was probably why, when the rest of the world was eyeing the emerging opportunities in the minicomputer market, the IBM never paid any attention, and even though IBM did succeed in capturing a large chunk of that market, it did not happen until Digital had captured the minicomputer market and had grown into a large corporation.

In the past few years, IBM has agreed to change the ways in which it conducts its business, and adapt to the changing times when the prices of computers…

Subtopic 6: Job management and protection; include a serious discussion of security aspects

The most commonly leveled criticism of operating systems is the inherent lack of security they have (Funell, 2010). Defining operating systems to have partitioned memory is just the start, as Microsoft learned with their Windows NT platform. Dedicated memory partitions by user account can be hacked and have been (Funell, 2010). The need for greater levels of user authentication is required, including the use of biometrics for advanced systems that have highly confidential data within them. The reliance on security-based algorithms that also seek to analyze patterns of use to anticipate security threats are increasingly in use today (Volkel, Haller, 2009). This aspect of an operating system can capture the levels of activity and the patterns they exhibit, which can provide insights into when a threat is present or not. The use of predictive security technologies, in…

The view opposing non-neutral networks is also articulated by one of the founders of the Internet, Vinton G. Cerf. "Allowing broadband carriers to control what people see and do online would fundamentally undermine the principles that have made the Internet such a success. "(Prepared Statement of Vinton G. Cerf...)

hile the cable and telephone companies do present some cogent practical and legal points, yet their rationale cannot measure up to the serious issues of democratic freedom and free access to information and content that a neutral network ensures. hile there is no perfect solution to this problem probably a middle ground could be worked out where the companies receive some control but do not infringe on the essential rights of freedom of expression and information.

The responses to a network security monitoring attack needs to be based on an assessment of the method of the attack that is being leveled against the network and its security monitoring, and thus can be as varied and complex as the attacks themselves (Bejtlich, 2004). Two tactics or tools that an attacker might use to attack network security monitoring are an attack from a stepping stone or an attacking using a spoofed source address. Both of these are methods by which the attacker uses tools and processes to hide their location and identity, making it more difficult to trace the origin of the malicious activity and thus to end it and also causing problems when it comes to the legal end of proving and prosecuting crimes. There are numerous methods of addressing attacks that utilize such tools, including different ways of attempting to track the true and hidden identity…

My significant other and I met in a traditional manner, at a nightclub.

Furthermore, most of our early relationship was spent in a conventional manner; we dated and spent time with each other, using CMC, such as texts and IMs as a way of relaying information about how we would spend our face time, rather than using it as a way to replace face-time. Then, life intervened, as it so often does, and an internship opportunity across the country separated us. Both of us being relatively poor students, we are unable to fly to visit each other frequently. Furthermore, while cell phones and unlimited calling plans have made it possible for us to talk a lot of the time, we have conflicting schedules, which can make it difficult for us to arrange times for any type of lengthy conversation.

The main lesson learned from viewing the tutorials and programs is the ease and flexibility of configuring each specific session to the unique needs of an audience. Feasibly these technologies could be used for creating highly unique and tailored learning experiences for students who were learning through online universities only for example. The ability to tailor all forms of digital content, from music and video to drawing boards and the inclusion of self-pacing materials, shows the potential of these technologies to support online learning over an entire semester for example (Suduc, Bizoi, Filip, 2009). The implications on long-term learning using these technologies is also significant. It is clear that the recursive nature of how they are designed would allow for repetitive study of complex concepts, including the more challenging areas of math, statistics and the sciences.

Network dating sites. How type dating evolved . Include pros cons.

Network dating sites have gained a particular place of social eminence within contemporary times. Online dating sites that members pay to use, such Match.com, made over a billion dollars in 2010 (No author). Many people consider these websites as primary options for dating for the simple fact that they allow expedient access to other singles who are also looking to date. Interestingly enough, these sites seem to have evolved from more conventional advertising for dating, which was traditionally found in print resources such as newspapers and weeklies. One may argue that the development of social networking web sites played a considerable role in the formation and popularity of network dating sites. Despite the degree of popularity these sites have, there are some inherent drawbacks associated with them that somewhat mitigates their efficacy. The most salient of these revolves around…

In less than one hundred years, air travel and networking and computing communications have evolved from the Wright brothers and the UNIVAC housed in several huge rooms to fully functional in-flight Gulfstream network communications. Passengers today expect their palm pilots, laptops and PC's to work as seamlessly as the flight itself. The modern day concerns are mired in the fact that digital conversation now entails a two way link that has inadvertently opened up a can of worms for airline network administrators.

Computer clustering involves the use of multiple computers, typically personal computers (PCs) or UNIX workstations, multiple storage devices, and redundant interconnections, to form what appears to users as a single integrated system (Cluster computing). Clustering has been available since the 1980s when it was used in Digital Equipment Corp's VMS systems. Today, virtually all leading hardware and software companies including Microsoft, Sun Microsystems, Hewlett Packard and IM offer clustering technology. This paper describes why and how clustering is commonly used for parallel processing, batch processing, load balancing and high availability.

Despite some challenges such as achieving transparency, mitigating network latency and the split-brain problem, clustering has proven to be a huge success for bringing scale and availability to computing applications. Hungry for even more efficient resource use, IT departments are now turning their eye on the next evolution of clustering called grid computing.

Once all of the hardware and networking is completed then this will represent the projects second major milestone.

The final project stage will be the one most prone to delays by it project historical standards. Since these are standard network servers however the project estimates that these can be installed in a relatively short amount of time. In fact, the budget estimates allowed for the servers to come fully installed with server operating systems directly from the factory. However, the project could potentially be altered in the software planning phase if it was deemed that purchasing the servers' operating systems separately provide any substance advantage.

To conclude the discussion of the projects activities, we will again revisit the project milestones; the first is the completion of the renovations to the floor designated to host the servers, related equipment, and personnel. The second milestone will be reached when all of the…

Network Alarms

Network Events, Alarms, and Alerts

It's not at all difficult to name and describe an event category or event-based transaction that can trigger an alert, alarm, or otherwise cause a network management system to bring something to the attention of a network manager; the difficulty is in limiting the description of such categories and transactions. Depending on the specific needs and architectures of the network and its users, the type of event or event-based transaction that might lead to the notification of a network manager could be pretty much anything. There are, however, some common event categories and event-based transactions that will trigger alarms or other notifications in the network management system and require attention form network managers. Several of these event and transaction types will be identified and described in the following pages, with their relevance discussed.

One broad category of events that commonly triggers alarms are…

Unfortunately, many consumers may not be aware of their photographic image being used in this fashion and even if they were, existing privacy laws fail to provide any substantive protections. For example, in response to these trends, the Harvard Law eview published an essay entitled, "In the Face of Danger: Facial ecognition and Privacy Law," with a majority of the article describing how "privacy law, in its current form, is of no help to those unwillingly tagged" (2007, para. 3). These issues have become even more salient because of the proliferation of social networking sites as discussed further below.

Privacy within social networking sites

Verizon is a leader in the communications industry. With an unparalleled service and strong brand equity, Verizon continues to uphold its market leadership among telecommunications providers. A key aspect of the success of Verizon is its network. Its network is ultimately the source of its vast profits, strong leadership, and globally recognized brand. The company's network also provides the company with economies of scale, lowering the per-unit cost per subscriber. This document will describe how the network is designed, offering insights as to why the design is effective. The documents will then often brief, incremental suggestion to improve the overall network capability.

To begin, Verizon Wireless is one of two major U.S. carriers that use CDMA2000. CDMA 2000 is a family of 3G mobile technology standards, which use CDMA channel access, to send voice, data, and signaling data between mobile phones and cell sites. The cell sites are important…

Computer Fraud and Abuse Act

Information technology and related systems provide multiple benefits to business, government, and individual users. Databases, Internet transactions, and emails contain sensitive customers, employee and operations data that are extremely vulnerable. The following study focuses on various components of IT and related systems used for the storage of information like computers, servers, and website databases. Whilst identifying the ways the date can be compromised and exposed to abuse, the study identifies ways of protecting and enhancing their integrity.

Types of information systems that that hold data

Computers

Computers do their primary work in parts that are not visible when using them. To do this, a control center that converts data input to output must be present. All this functions are done by the central processing unit (CPU) a highly complicated set of electric circuits that intertwine to store and achieve program instructions. Most computers regardless of…

Network Implementation for Davis Networks Inc.

In the proposal, effort is made to develop an affordable local LAN for Davis Networks Inc. The effort involves provision of wireless Internet connection to all individuals for their desktops and laptops from the current high speed connection they have at an affordable price (800 USD -- 1000 USD). Provision of the internet to the same location costs approximately 700 USD including all other expenses like doing the wiring etc. To implement the project, there are various obstacles that have to be considered like electric poles, trees and walls. The core location is the Computer Center building. It has the highest speeds of connection. From this building, there will be distribution to the surrounding buildings located between 500 and 1000 meter range. The establishment of the network needs 5 Wireless Access points (WAP) having Omni antennas (A, B, C, D, E) and two directional…

Another aspect of the security management area of a network management system is the development of policy-based auditing and alerts by role in the organization

(Merilainen, Lemmetyinen, 2011). This is one of the areas of knowledge-enabled security management, specifically in the area of role-based access and advanced auditing and reporting.

Fault management is also an area that no single suite of network management systems can completely meet per the ISO standards today. This requires the CIO and network managers to define specific goals in this area including the extent of fail-over support and use of advanced fault tolerance technologies (Netak, Kiwelekar, 2006). Accounting management baseline performance includes the ability to generate logs of performance and also define benchmarks for performance. This is the minimal level of functionality a CIO and network manager need to consider when selecting a network management system. Configuration management systems requirements range from the relatively simplistic…
