Virtual private networks technologies and solutions pdf
A Survey of Mobile VPN Technologies - IEEE Journals & MagazineA v irtual p rivate n etwork VPN is a network that is constructed using public wires — usually the Internet — to connect remote users or regional offices to a company's private, internal network. A VPN secures the private network, using encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. 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. The information transmitted between the two locations via the encrypted tunnel cannot be read by anyone else because the system contains several elements to secure both the company's private network and the outside network through which the remote user connects through. The first step to security is usually a firewall between the client and the host server, requiring the remote user to establish an authenticated connection with the firewall.
Virtual Private Networking
For many years Russian residents have been banned from viewing tens of thousands of websites, mostly those sharing copyrighted material. But many residents decided not to bend to these new rules willingly, rather opting for virtual private networks to help them surf online anonymously. A new bill just signed into law by President Vladimir Putin requires every service provider that allows people to view blocked domains to stop. The use of virtual private networks, or VPNs, to circumvent government or other types of restrictions online is in no way restricted to Russia. On the other side of the world, Australia is fast becoming an unlikely hotspot for digital disobedience after Google started removing illegal streaming sites following a court order. However, many tech experts warn that merely banning these sites and restricting access is not enough because it can be bypassed in seconds using a VPN.
