Blocking/Locking after x failed ssh attempts

[datadan]

Good Day.

I am getting an increased number of attempts to access my (rehat 9) server through sshd attacks.

I would like to have my machine lockout/not even allow attempts from the same source for a certain period of time after 3 or 4 failed attempts.

Is this possible? If so how?
Any help is appreciated.
Thank you
