The SYN (TCP connection request) attack is a common denial
of service (DoS) technique characterized by the following
pattern:
- Using a spoofed IP address not in use on the Internet,
an attacker sends multiple SYN packets to the target machine.
- For each SYN packet received, the target machine allocates
resources and sends an acknowledgement (SYN-ACK) to the source
IP address. This can cause the target machine to allocate
resources for more than 3 minutes to respond to just one i
SYN attack, hence wasting resources.
