Port numbers are not so controlled, but over the decades certain ports have become standard for certain services. The port numbers are unique only within a computer system. Port scans are more common than most people think. Not all of them are malicious. Not every Internet security package does a good job of accurately identifying a port scan.

This means that people trying to connect to your computer. They scan your ports to find an entry! See in "advanced settings" of Bitdefender (by consulting the help you will see the boards). The message from bitdefender that is used to secure your computer.

if you want to block the port scan you can do this :
# Drop port scanning packets
-A portscan -m limit --limit 1/sec --limit-burst 2 -j RETURN
-A portscan -m limit -j LOG --log-prefix "iptables scanned: "
-A portscan -j DROP
