  1. Jason Moore says:

    The TCP syn is not an attack to start. It is a method that pen testers use to fingerprint a nodes on a network. I imagine that if flooded from different IP’s that it is possible to DDOS a system, but I can not see this being used as an attack vector.

This uses up the resources of the target’s(victim)resources and could lead to denial of services for legitimate users if necessary security measures/thresholds are not in place to stop such DoS attacks.
