This paper will Describe in detail what Virtual Private Networking is and how it is used in companies. It will cover all of the benefits, as well as the problems encountered in achieving success with this facilitator of social software. It will give examples of companies and how they use the technology, it will provide case studies of companies that have used the technology successfully. It will review the author’s thoughts of how to use VPN in a common workplace.
Then it will show you how to implement VPN on a network, through both hardware and software installations. You will see how employees collaborate with this tool and use it to increase productivity. You will see the obstacles that you would encounter with a VPN system and how to overcome those obstacles and solve problems that might occur in its everyday use.
Later in the paper you will see the more popular products available that support VPN and you will also see a price comparison of those products. Near the end of the paper you will see an estimate that adequately shows the cost of full implementation in a business workplace.
A virtual private network (VPN) uses a public network infrastructure to make the connections among geographical dispersed nodes. It can also be described as a logical local area network that connects an organization’s geographically dispersed sites in a way that makes them appear to be part of one single network. A VPN differs from a typical wide area network in the following way. Instead of a hardwired pipeline between nodes of a standard wide area network using a dedicated connection, the connections of a VPN are made through a web of cables of a public network such as the Internet.
There are several ways a companies use a VPN. A VPN can do anything a leased line wide area network can do and more. Companies connect to geographically distant facilities into a cohesive network. By using the international resources of the Internet, a VPN can offer connectivity virtually anywhere in the world. This allows a company to expand globally. Company use VPN for remote access services. It is not only an extremely cost-effective way to service a mobile workforce or telecommuters but it allows workers to connect into the home office through an Internet service provider from anywhere in the world, riding through a public Internet to l...

...igh performance techniques that are available. This series is the “most feature-rich carrier-class VPN product line on the market.”(digital warehouse) The concentrator ranges from $5,000-$19000 as the Encryption Service Processor ranges from $40,000-$60,000 and the Power Supply Spares and Options are from $50-$5,000.
The cost for a system to be installed in a company mainly depends on the size of the company. The smaller companies will typically use the less expensive and the larger the companies will use the more expensive system. Overall, for a high quality VPN system a company would pay about $8,000. This price depends on whether or not the company needs the accessories or an upgrade kit or spares for the system.

Server-based networks are higher in cost because money is invested for dedicated servers, network operating software, and network administrators with technical expertise required for network management and configuration. On a small network consisting of fewer than five workstations, client/server architecture is not recommended and is very costly.
TOR (Roger Dingledine) is a circuit based low-latency anonymous communication service. TOR is now in its second generation and was developed from the Onion routing program. The routing system can run on several operating systems and protect the anonymity of the user. The latest TOR version supports perfect forward secrecy, congestion control, directory servers, integrity checking and configurable exit policies. Tor is essentially a distributed overlay network which works on the application layer of the TCP protocol. It essentially anonymizes all TCP-based applications like web-browsing, SSH, instant messaging. Using TOR can protect against common form of Internet surveillance known as “traffic analysis” (Electronic Frontier Foundation). Knowing the source and destination of your internet traffic allows others to track your behavior and interests. An IP packet has a header and a dat...
As technology improves, businesses expand and recruitment pools decrease, organizations contemplate ways to, not only reduce the overhead costs of doing business but, to attract new talent in a competitive employment marketplace (Darleen, 2012). To do so, many organizations have redefined what it means to ‘go to work’, in terms of not only the act of getting there, but how work is accomplished and where (Lojeski & Yuva, 2008). A study conducted three years ago by the Society For Human Resource Management (SHRM) reported that almost half of the organizations surveyed utilized virtual teams (Minton-Eversole, 2012). Anyone who conducts business using mobile technology devices is considered

In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
Virtual Private Network presents some advantages over the traditional network technologies. VPN offers direct cost savings over leased lines or long-distance calls for remote access, savings resulting from reduced training requirements and equipment, increased flexibility, scalability, and security. The main advantage of VPN is the cost savings of Internet VPN when compared to networks built using conventional leased lines. Leased lines include tariffs that have an installation fee, a fixed monthly cost, and a mileage charge. The cost to an organization of traditional leased lines may be reasonable at first but can increase exponentially as the organization grows. As an organization grows and more companies must be added to the network, the number of leased lines required increases dramatically. VPN that utilizes the Internet avoids this problem by simply tapping into the geographically distributed access already available. Another way VPN reduces costs is by reducing the need for long-distance telephone charges for remote access. Instead of having the offsite team of a company dial into the corporate modem bank via long distance lines, the company’s VPN allows them to simply place local calls to the ISP’s POP in order to connect to the corporate network.
A reliable environment for teams to exchange information in a secure manner may be a necessity for virtual teams; therefore, security can pose another challenge. Different types of projects may require different levels of security. A virtual private network may be necessary to ensure that information is passed securely to the desired recipients. Authentication and encryption techniques can guarantee secure transmission of electronic...
The methods of communicating for a virtual team consist of different tools than used by a traditional team because “…awareness of others’ activities is more difficult and requires some degree of technological intervention” (Fussell et.al., 1998, p. 276). A virtual team needs to use alternative tools because it has members working from different geographical areas and possibly at different times. A traditional team meets face to face, whereas a virtual team needs the use of technology to operate and interact efficiently. Teleconferencing, video conferencing, faxing, e-mail, and instant messaging are some of the tools available to a virtual team.
Virtual corporations have some major characteristics (Judith, 2002, quoted in Byrne. n.d.) as following state: technology, excellence, opportunism, trust and no borders. Technology makes distance no longer a problem while entrepreneurs or companies far away from, due to the computer networks link people all over the world. Excellence was showed by each partner bringing its core competencies to the corporation, which can exert all advantages. Companies make alliances for specific market opportunity and this is a more efficiency work way than any others. Members in a virtual organization must trust their partners due to they meet the need by cooperating. The new communication ways were brought by computer networks, which blur the traditional hierarchies and boundaries.
In today’s virtual society our office experience is getting more and more dependent on cyber culture. Due to the increase in employees working at home, virtual offices have become a convenient way for staff, clients, educators, students and all other types of business people to stay connected. Teleconferencing, skyping, e-mails, and texting have become mainstream ways of conducting business so it seems pertinent that businesses learn to effectively create and conduct virtual teams.
Corporate Networks in organisations can be complex structures that “requires a great deal of attention” (Clemm 2007). Even small companies can have quite complex networks that are a considerable investment to the business. The notion that corporate network management is a cost to a business rather than a continual beneficial investment is a naive assumption that requires further investigation to the benefits that network management brings. Clemm (Clemm 2007) states in his text that the ultimate goal of network management “is to reduce and minimize total cost of ownership”, improving operational efficiency and lowering cost. Clemm (Clemm 2007) also notes that “Network Management is not just related to cost and quality”, which will be an continual concept presented throughout the report. The report will address key issues with corporate network management and ultimately argue and justify that corporate network management must be seen as a positive benefit to the business and not as a continual expense. The supporting articles will also provide sound evidence that networking is crucial to a business’s processes and production which can be seen from the OpenSSL Heartbleed Security vulnerability fiasco (Nieva 2014) or the QANTAS Amadeus system failure (Heasley 2012).
To reiterate these six components, which are innovation, technical package, communication, management, and political commitment – the community is hand in hand associated with core functions of Public Health. In Public Health the three main core functions are assessment, policy development, and assurance. Assessment is a tool that helps monitors different health and environmental statutes to create, deploy, and identify solutions. It also used a diagnostic tool to investigate health-related problems and different health hazards. Policy development is an act of informing and educating those developed ideas and topics that help the communities and different organizations in their health care efforts. Lastly, assurance utilizes different laws and regulations to help in the aid of protecting the public or environment at risk. It also re-evaluates the laws and regulations to see its effectiveness and its quality (Schneider,
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
Due to the demand for the internet to be fast, networks are designed for maximum speed, rather than to be secure or track users (“Interpol” par. 1). The adage of the adage.... ... middle of paper ... ...
