You really can't stop port scanning.

Review your rules and make sure you aren't exposing anything they can exploit. Consider adding ACLs to block their IP before they get to the firewall.

There isn't a whole lot you can really do. Just keep your system secure. If you have no holes, you will be fine.

If anything, you should be more worried about the humans on the inside of your network. Hackers are much more likely to breach there than your firewall.
