Hi,

I don't know how to do it with checkpoint specifically.  However, I use a 
freeware
called Simple Event Correlation (SEC) and it takes the checkpoint log that I get
through a LEA server.  From there, with the data in place, I write SEC rule
to do just what you want to accomplish.  SEC is a very powerful tool and it is
free.  Not only it can take log from Checkpoint, it can also takes logs from the
SSH server, NetFlow data and other things and based on the rules you specified,
it can tell you if your system has been compromised and what you want to do
with that information.

Good luck

Is there a chance to detect SSH brutforce to Servers in the DMZ by
Checkpoint?
For example blocking a specific IP after 3 SSH connections in 1 Minute?

I thoght about using SmartDefense "Successive Events", but there I can't
specify a Server..

I have NGX R61, is there something that can help me? Is there something
in the newer Versions?

I'd like to avoid implementing such a Blocker on the DMZ Servers, wich
of course is possible.

Thx for help!

regards Markus
