There is already a timeout after each bad password from the same ip address.
Time between each try increase.

If you use vnc to give support on a pc with some user, you can add the "required accept". Then the hacker always
get the refused by user answer.

Try to use another port the 5900, most hackers scans only that port for vnc access.

I infer from this that the timeout can be increased. Where is this setting changed?
