IP Address Spoofing

IP Address Spoofing

IP Spoofing is a technique which is used to gain unauthorized access to computers, whereby the squatter sends messages to a computer with a false IP address to indicate that the message is coming from a trusted host. In other words it is a process of returning IP address that is different from the one that is actually assigned to the destination website.

To involve in IP spoofing, the intruders use a variety of techniques to find an IP address of a trusted host and then modify the packet headers so that it appears that the packets are coming from that trusted host.

In case IP spoofing is used to hijack a browser, whenever any visitor types in a legitimate site’s URL, he is taken to a fraudulent Web page of the intruder. For example if the intruder has spoofed a popular ecommerce website, then any Internet user who would type in the URL of that particular site would be redirected to the spoofed content created by the intruder.

If a user interacts with dynamic content on that spoofed page, the intruder can gain access to sensitive information on the particular computer or network such as a credit card number or password, or install malware.

IP Spoofing is a big no no when in terms of SEO as it is considered a black hat seo technique. Newer routers and firewall arrangements can help protect your network from these malicious cloaking and cracking techniques.such as IP spoofing.

  1. one should always keep his / her System updated with patches and updates for OS as well as installed softwares.

    Firewall is always a good option on both Linux as well as Windows OS. iptables can be tweaked on Linux to have good firewall settings while on windows one can consider System Mechanics or Fprot software firewall.

    Cisco ASA 5510 would be the best if one is willing to pay its costs :)
