TCP SYN Attack

[abbase]

I have P4 machine, on which Windows Xp has been running as my operating system. I would like like to know that what is TCP SYN attack? Is TCP SYN attack dangerous for our system? Does any body have any idea about it? Let me know your views on the above topic. Any help you can provide would be greatly appreciated.

The TCP SYN Flooding attack consists of a tool that only implements one portion of the Sequence Number Guessing attack, with a completely different focus. There is a potential denial of service attack at internet service providers (ISPs) that targets network device. A sender transmits a volume of connections that cannot be completed.

TCP Syn Attack is a type of denial of service (DOS) attack in which a sender transmits a volume of connections that cannot be completed. While SYN attacks may not be entirely preventable, tuning the TCP/IP stack will help reduce the impact of SYN attacks while still allowing legitimate client traffic through. The SYN flood attack sends TCP connections requests faster than a machine can process them. This causes the connection queues to fill up, thereby denying service to legitimate TCP users. A TCP SYN attack (also called SYN attack) is a common type of Denial of Service attack.

TCP "SYN" Attack is also known as SYN Flooding. It takes advantage of a flaw in how most hosts implement the TCP three-way handshake. The TCP SYN attack exploits this design by having an attacking source host generate TCP SYN packets with random source addresses toward a victim host. Using a spoofed IP address not in use on the Internet, an attacker sends multiple SYN packets to the target machine. This causes the connection queues to fill up, thereby denying service to legitimate TCP users.
