Object

column SNMPv2-SMICounter64 
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.
              
This attribute records the number of SYN attacks.
