In simple words, IP Spoofing can be stated as “Hiding your Systems IP address from others”. It is essentially a technique used by hackers to gain unauthorized access to Computers. Concepts of IP Spoofing was initially discussed in academic circles as early as 1980. IP Spoofing types of attacks had been known to Security expert on the theoretical level. It was primarily theoretical until Robert Morris discovered a security weakness in the TCP protocol known as sequence prediction. Occasionally IP spoofing is done to mask the origins of a Dos attack. In fact, Dos attacks often mask the actual IP address from where the attack has originated from.
Virtual Private Network(VPN):
Virtual Private Network Provides us a secure way to serf less secure networks, it helps us in IP spoofing so that no one can access your personal information without Authentication. It is a technology that creates a safe and encrypted connection over a less secure network, such as the internet. A Virtual Private Network is a way to extend a private network using a public network such as the internet. The name only suggests that it is a Virtual “private network” i.e. user can be part of a local network sitting at a remote location. It makes use of tunneling protocols to establish a secure connection.
