Short explanation on portscans and attacks: Most portscans scan the lower well known ports (Well known ports) to find services (e.g. FTP servers, SMTP servers, etc) so they can exploit them to get access to the machine.
What is automatic port scan detection?
In its simplest form, the port-scanning software asks about each port, one at a time. The remote system will respond and say whether a port is open or closed. The person running the port scan would then know which ports are open.
