IP Security

The Internet Protocol (IP) is the message-delivery portion of the TCP/IP suite. It provides the address and delivery of data packets. This is a "best-effort" delivery system that does not guarantee the arrival of packets or that the information is properly sequenced. Thus, IP packets can be intercepted en route, reviewed, and even modified. The potential misuse is obvious. Let's take a second to examine some IP security issues.

IP spoofing can be a major threat. The IP address is ordinarily shown as plain text. The hacker can then direct the packet to the destination with altered information. The use of cryptographic technologies is the best defense against IP sniffing and spoofing.
