SSH password lockout

I looked through the security logs and found 300+ login attempts from many different IP addresses.

Is there a way to lockout an IP address for X minutes after a few failed login attempts?
 
Not really. Your best options are to: use keys for authentication, move SSH to a non-standard port, block SSH connections from all but a couple of ip addresses
