what is difference between syn flood and port scan attack?
问题 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. 回答1: The purpose is to consume tcp backlog for both 'half-open' and 'open'. http://www
