FIN scan a port scanning techinque that hackers use to see which ports on your computer are penetrable by knocking on the port like a door. it works by sending a FIN packet to a target port then the target system sends a RST for all closed ports. FIN scan can identify all closed doors and then give you a list of all open ports. most system donot realise this is happening because its handle by the lowest level of the operating system.
