In this era of fast moving technological innovations and development, one area that has lag and yet unable to match feet with the pace is online security and anonymity. Though we have opportunity to go online while on the move, we don’t have surety just how secure we are. An old proverb fits well here, Prevention is better than cure. You should take preventive measures before it’s too late. In this article our focus would be VPN and online security and anonymity. While I was surfing the internet, I came across many interesting websites that have been offering remote VPN accounts, they are for your sure security and anonymity online with a price tag equals that of an anti-virus license. Let me explain how it works and what is needed on your part to get a VPN.The VPN providers have setup remote servers at various locations worldwide in various data centers. They may be at diversified locations like USA, UK, Canada, Germany etc. On the server side generally if Windows they may be using built-in RRAS (Remote routing Access) that is configured to route (or NAT) your connection to the other side (Public Address on Internet) while you get a private address from a predefined pool in there. There could principally three flavors, namely Shared IP, Dynamically Shared IP and Dedicated IP. A shared IP or a static shared IP means every time you connect (dial their server) you get similar IP address. Dynamic shared IP means every time you connect you get a different IP (from a pool of Public IP addresses, may be /24 or /25 or other). Whereas a dedicated IP would mean you will get a similar IP every time you connect but that is not shared with anyone else. In short static shared IP address is more like an open-proxy as it begin used by more than one person at a time, dynamic shared IP is not much like proxy, its concept could be understood by thinking its IP allocation as that in ADSL. Dedicated IP, as name suggests, gives you a unique IP that is solely yours and there is no point in any kind of trouble like Black listed IP, UCE listings. You should first check IP status before going to get a dedicated IP.In order to connect to a VPN server, VPN providers provide dialers (that are actually made using a utility called, CMAK, found in windows server), generally two protocols are provided PPTP and L2TP, as your network might support either of the two. Once you are connected, all your internet bound traffic goes to the VPN provider server and from there it’s routed to internet. Incoming traffic follows the similar procedure, thus your identity is completely hidden from rest of internet. Wherever you browse its VPN provider server IP that would be visible and your IP would be hidden. Most impotently all your data that travels between your PC/MAC and secure VPN connection provider goes encrypted thus leaving no room for data loggers and hackers to intercept your traffic (passwords and private information) in a readable form.There are unlimited benefits for such a service. Some are bypassing local internet filters, bypassing blocks on particular websites, unblocking VOIP where it’s blocked; for example UAE, Oman, Saudi Arabia and other ME countries. VPN is also considered as work around for streaming country-specific media e.g. if a media is limited to be accessed from USA, and you get a USA VPN you could watch the media as if you were in the USA. Same goes all countries.
