VPN stands for Virtual Private Network. VPN is a data network connection that makes use of the public telecommunication infrastructure but maintains privacy through the use of a tunneling protocol and security procedures. It operates much like a Wide Area Network (WAN). Most companies actually leased lines, but in either case both solutions are very expensive. As the Internet became more widely available people started creating VPN solutions that took advantage of the cheap network access. The idea

Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPN's permit secure, encrypted connections between a company's private network and remote users through a third-party service provider. A VPN can grow to accommodate
user to log onto a network from a distant location. This is accomplished with a remote computer connected to the distant network. Whereas remote control refers to taking control of another computer, remote access means that the remote computer becomes a work station on the network. Communication between the network facility equipment and the remote computer is accomplished through a data link. The only difference between a remote user and workstations connected directly to the network is slower data
the Intranet and the Extranet. Internet The Internet is a public, global network of networks which is based on Internet Protocol (IP) and related standards (http://www.teleshuttle.com/media/extradef.htm). The Internet was designed to provide a standard means of interconnecting networks so that any system could communicate with any other system, regardless of physical location. It operates as a confederated network of networks (an "internet"), and offers universal accessibility (http://www.teleshuttle
relay is a communication method that transfers data by dividing information into packets and sending them over a virtual network. Frame relay is a difficult process to understand and to accomplish. Leased lines, however, is the permanent connection between two stations. Leased lines are simpler to understand and do not take a lot of effort to achieve. According to Computer Networks, frame relay came into existence to overcome the complex protocols caused by slow telephone lines, and expensive
Introduction Android operating system is one of the most popular mobile operating systems.

Mobile phones are not only used for communication, but for educational purposes,getting location, for social networking sites, clicking pictures and many more. Hence, mobile phone have become an inseparable part of our daily life. With the increase in usage of smartphones, there
possible to remain private online while using the internet effectively. Certain methods of remaining anonymous online will have different difficulties in order to follow them, I will take this into account when I am analysing my findings as not everyone who wishes to remain private online is going to be computer literate. I will also take into account that the internet is accessed through a range of devices (mobiles, tablets, and desktop PCs) so I will focus on remaining private
Network Security 1. What is network security? Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself. Threats to your network is becoming more
Conversation started April 2 Sai Gokul 4/2, 4:36am Sai Gokul There was an era where physical security was considered to be the most effective means of protecting technical systems. But this era became obsolete with the advent of telephone networks and modems which necessitated the protection of data as well as the systems with the help of Informatics. The significant contribution of Informatics in the field of security was the development of RSA encryption algorithm -in the late 1970s- that utilized
Benefits of Having VPN A Virtual Private Network, more commonly known as VPN, is a type of technology that provides secure private connection for users who connect to public networks, such as the Internet or company network. It is a safe and secured channel through which data are transmitted without exposing these data to anyone. Many people are still new to VPN use, but a lot of companies all over the world are already using them. People need to understand its benefits so that they can take advantage
this is magic!" I exclaimed as I read 'Tom' on the screen. While I realized intuitively that a complex version of this elementary network could achieve much, at the time I had no real idea what. Now, four years later, I know that Networking makes possible a plethora of applications, from video-conferencing over the Internet to linking banks through private networks. It still seems like magic. Or rather, a grand adventure - one that I most certainly want to be part of. My interest in applied science
computer or network access from a remote location. Today many business people who travel often need to have remote access to their corporation's network. There is however vulnerabilities that all types of remote access have common, and it doesn’t matter what method used, the endpoint machine is vulnerable like all other systems that have access to the Internet. Whenever a system is accessible via the internet, that system is exposed to danger. Analyze the Quick Finance Company Network Diagram and

Network Security In the last decade, the number of computers in use has exploded. For quite some time now, computers have been a crucial element in how we entertain and educate ourselves, and most importantly, how we do business. It seems obvious in retrospect that a natural result of the explosive growth in computer use would be an even more explosive (although delayed) growth in the desire and need for computers to talk with each other. For quite some time, businesses were primarily interested

Public key infrastructure and digital certificates help companies battle the wave of illegal activity and enhance the business models. Today many businesses are using firewalls as a way to add security to a network. Virtual Private Network allows users to gain secure access to its organizations network. Companies that have used these technologies are paving the way for future security methods. Encryption and decryption are always used whenever secure sites are accessed so that users that enter information
provide authorized access only into a network. This review will look into the common security features that are present within firewalls and how they are used in daily functions to help prevent issues that threaten organizations. Firewalls work by preventing unauthorized access into a network by monitoring and enabling / disabling traffic via security policies and procedures. Grimes states, “Firewalls work by inspecting and filtering packet traffic between two networks. Firewalls are categorized according
Each virtual network in a network virtualization environment is a collection of virtual nodes and virtual links. Essentially, a virtual network is subset of underlying physical network resources. Network virtualization proposes decoupling of functionalities in a networking environment by separating the role of traditional ISPs into InP’s (Infrastructure Providers) who manages the physical infrastructure and SP’s (Service Providers) who creates virtual networks by aggregating resources from multiple
