How to Prevent IP Spoofing

Prevent IP Spoofing

Introduction:

An IP (Internet Protocol) address is the address that reveals the identity of your Internet service provider and your personal Internet connection. The address can be viewed during Internet browsing and in all of your correspondences that you send.
IP spoofing hides your IP address by creating IP packets that contain bogus IP addresses in an effort to impersonate other connections and hide your identity when you send information. IP spoofing is a common method that is used by spammers and scammers to mislead others on the origin of the information they send.
IP spoofing is a security exploit and can be prevented from placing nospoof on in host.conf file. Edit the host.conf file and place the following lines. If you run dns bind, give it preference.

Steps:

1. login to server as root
2. vi /etc/host.conf
3. and add following line

nospoof on

4. save and exit
