As Internet usage grows exponentially network security issues newlinebecome increasingly important Network security measures are needed to newlineprotect data during transmission Various security controls are used to prevent newlinethe access of hackers in networks They are firewall virtual private networks newlineand encryption algorithms Out of these the virtual private network plays a newlinevital role in preventing hackers from accessing the networks A Virtual newlinePrivate Network VPN provides end users with a way to privately access newlineinformation on their network over a public network infrastructure such as the newlineinternet Using a technique called Tunneling data packets are transmitted newlineacross a public routed network such as the internet that simulates a pointtopoint newlineconnection newline newline
