  Internet protocol spoofing - Wikipedia, the free encyclopedia
For example, Transmission Control Protocol uses sequence numbers negotiated with the remote machine to ensure that arriving packets are part of an established connection.
Protocol spoofing is also used as a data compression technique, and was used as early as 1985 when the Hayes Smartmodem incorporated spoofing of portions of the UUCP protocol to improve throughput.
The term spoofing is also sometimes used to refer to header forgery, the insertion of false or misleading information in email or netnews headers.

 Spoofing attack - Wikipedia, the free encyclopedia
A spoofing attack, in computer security terms, refers to a situation in which one person or program is able to masquerade successfully as another.
An example from cryptography is the man in the middle attack, in which an attacker spoofs Alice into believing he's Bob, and spoofs Bob into believing he's Alice, thus gaining access to all messages in both directions without the trouble of any cryptanalytic effort.
Alice's firewall can defend against spoof attacks when it has been configured with knowledge of all the IP addresses connected to each of its interfaces.

 Encyclopedia: Internet protocol spoofing
The Internet Protocol (IP) is a data-oriented protocol used by source and destination hosts for communicating data across a packet-switched internetwork.
An IP address (Internet Protocol address) is a unique number, similar in concept to a telephone number, used by machines (usually computers) to refer to each other when sending information through the Internet.
UUCP stands for Unix to Unix Copy Protocol, and is a computer program and protocol allowing remote execution of commands and transfer of files, email and netnews between Unix computers not connected to the Internet proper.

Concerns about intruders attacking Pitt's Internet computer network, and the machines attached to it, through IP spoofing or terminal hijacking have surfaced at the University since an article on the method appeared in the Jan. 23 issue of The New York Times.
IP spoofing makes use of a flaw in the design of the network to fool router computers into believing that a message is coming from a trusted source such as a member of the University community with a CIS account.
As of October 1994, according to CIS's Carpenter, the Internet is connected to more than 3.9 million hosts and 56,000 domains such as universities, businesses and government agencies around the world, which means the break-ins have been very, very few compared to the number of computers connected to the network.

Note 1: An attack using IP spoofing may lead to unauthorized user access, and possibly root access, on the targeted system.
It is possible to route packets through this type of firewall if the router is not configured to filter incoming packets having source addresses on the local domain.
Note 4: A method for preventing IP spoofing problems is to install a filtering router that does not allow incoming packets to have a source address different from the local domain.

 IP Spoofing: An Introduction
In IP spoofing, an attacker gains unauthorized access to a computer or a network by making it appear that a malicious message has come from a trusted machine by “spoofing” the IP address of that machine.
Internet protocol (IP) is a network protocol operating at layer 3 (network) of the OSI model.
Both types of spoofing are forms of a common security violation known as a man in the middle (MITM) attack.

The protocols are correctly implemented in Windows NT 4.0 and Windows 2000, but, by design, they are vulnerable to misuse and spoofing.
This could allow any machine on a network to spoof a WINS server and send a name conflict or name release datagram to another machine, thereby causing the machine to abandon its name and be unresponsive to requests for service.
Under the protocol, if a name conflict were detected, the WINS server would send a Name Release demand to one of the machines claiming the name.

 Email Spoofing
E-mail "spoofing" is the act of altering an e-mail header so that it appears to have been sent by someone other than the actual sender.
Some spoofed messages are from hackers trying to cause outrage by sending a damaging e-mail apparently from a well-known person or organization.
Spoofing generally isn't illegal because no hacking is required, FBI officials say, leaving prosecutors with little recourse unless there's a threat of death or violence involved.

 Internet Address Spoofing and Hijacked Session Attacks
These attacks are based on the exploitation of two separate vulnerabilities: forging or spoofing the source address of IP packets and hijacking already established login sessions.
The IP spoofing attacks are very similar to those described in section 2 of "Security Problems in the TCP/IP Protocol Suite" by Steve Bellovin.
Currently, the best defense against IP spoofing attacks is to filter packets as they enter your router from the Internet, blocking any packet that claims to have originated inside your local domain.
