Introduction – The Past:
Thirty years ago, there was no such need of privacy and data encryption as the Internet age had not taken off. In the 90s, VPN technology was still a fairly new technology but was predicted that it would be the next big thing in the early 2000s. Only large companies could afford the price to use dedicated lines to connect to remote locations. However, the disadvantages of the lease line are quite clear: Although large companies have the capitals and needs for building private networks, small and medium companies could rely on the less expensive, packet switched X.25 network. As the size of the Internet continued to grow, both small and large companies began to connect their private network with the public network. This brings a convenience but with one obvious problem – privacy and security.
Virtual private network (VPN) was developed in 19XX by Stan Hanks, who build IP VPN based on TCP/IP-over-X.25 stack for CSNET. Its goal was to ensure privacies and data integrities of communication and information. Thanks to the helps of many engineers and people such as XXX decided not to patent the XXXX technology when he was in Microsoft, VPN technology was growing rapidly during the early 2000s. Over the year, its flexibilities make travelled businessmen able to connect back to their companies’ networks, it also made employees work from home possible. Although some may argue that this makes the line between home and work space less clear, others claim that it
Virtual Private Networks (VPNs) are used to allow a remote public connection to an internal network. A VPN is essentially a virtual tunnel connecting a remote user (Tunnel Vision). The traffic within the VPN tunnel is encrypted, and there are two ways to do this. One way is Internet Protocol Security (IPsec) and the other is Secure Sockets Layer (SSL).
In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in
Risk Management or Assessment To lessen the exposure of the corporate network to outside sources, there are many matters to consider. Areas of concern with the VPN client that should be addressed include: the potential hazards of the “always connected” nature of broadband Internet connections, installation of personal firewalls, antivirus software, and the remote PC itself. Analysis of the client PC begins with the PC itself. It is recommended that security policy require the VPN host to be company issued equipment, rather than using the existing user’s personal property. This eliminates problems associated with mixing business and personal information. When under company ownership it is easier to require the end user to comply with policy, and insist the PC be used only for business-related purposes. As the hardware is company-owned, users will not be given administrator account rights on their desktop machines. Controlling user activity as well as checking and maintaining desktop integrity is very difficult (if not impossible) when users have complete control through administrator rights. Company provided hardware also serves to minimize management issues, as the computer should remain relatively static - with no unauthorized software installations, end-user configuration changes or device conflicts to troubleshoot, support calls are reduced. In addition to
Versa VPN is working as VPN vendor since 2010 to facilitate the users with secure and anonymous browsing. They provide an above average service to their clients with their business philosophy to deliver the best internet security with finest levels of quality keeping it within the reach of common internet users. Versa VPN suppliers maintain its quality and make sure it users’ end by restricting 20 number of clients at each server. They are providing best customer care support through different methods including email address, telephone number, ticket support, Twitter account, and Live Chat option. They also ensure a reply to every query within 30 minutes.
A VPN is a private network that uses a public network (usually the Internet) to connect

VPN refers to the networking technology Virtual Private Network. A VPN allows users connected to this network the ability to access any website or computer data from any location in the world with dedicated and secure networking environment rather than being present in a public server. Majority of VPN users belong to business class industry and educational purposes. VPN networks are used in this manner because majority of VPN networks offer the features like encryption and anonymity which increases the privacy and security benefits while using the VPN network. VPN networks also allow the user ability to perform activities on the internet as if they were accessing
VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].
2.. Security standards: When working mobile, one is dependent on public networks, requiring careful use of VPN. Security is a major concern while concerning the mobile computing standards on the fleet. One can easily attack the VPN through a huge number of networks interconnected through the line.

This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.
I believe that the VPN and its respective protocols is a very important step towards securing the Internet and all the data that travels over it every second of every day. In the future I think that there will be yet a faster, even more secure and reliable private connection, only 15 years ago or so the VPN was primarily a land line based technology, using common twisted pair for connection over a modem and going through a tel-co switch. In only 15 years we have progressed to optical networks, wireless networks, VPN networks of varying flavors. VPNs sound secure, and in theory they are, however, as with all technology and advances made towards protecting our data from unauthorized access by anyone who is not the intended recipient, is inevitable. Just recently the VPN protocol was breached, a way around the protocols and encryption was discovered and exploited. The hackers were able to circumvent two of the most trusted privacy tools on the Internet: virtual private networks, or VPNs, and Tor, the anonymity software that masks a computer’s true whereabouts by routing its Internet connection through various points around the globe, according to findings by Jaime Blasco, a security researcher at AlienVault, a Silicon Valley
VPN configurations will be used between each location to ensure site-to-site connectivity. The VPN will allow employees to access the company's intranet from home or while traveling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.[6] which will
SSL VPN is a newer VPN technology that links an employee’s computer to a corporate network via a web browser. No client software is required, meaning a larger variety of operating systems are potentially supported. The third type of VPN is mobile, in which one of the endpoints of the tunnel is not fixed (Bridwater, 2013).
The intent of this security proposal is to ensure the ongoing protection and data security for a government agency's data center. Security and access privileges will be defined at the role and department levels, with added authentication for system administrators and members of the IT staff. Role-based access to this government facility will be tracked continually and reported using real-time log reporting and analysis (Amsel, 1988). This role-based approach to managing security will provide for inclusion of authentication, detection and deterrence in the areas of social engineering, firewalls, Virtual Private Networks (VPNs), authentication, security protocols and vulnerability assessments.
