title: what is difference between syn flood and port scan attack?
body: <p>i am confused based on the difference between SYN Flood and Port scan attack.
  knowing that TCP SYN Flood is often referred to as "half-open" scanning, because you don't open a full TCP connection. You send a SYN packet, as if you are going to open a real connection and wait for a response. 
  Port Scan varies destination port but i think they have similar operations, if not please i need clarifications.</p>
