Thank you for this. Is it possible to direct the rule to look at specific device for attempted SSH logins?

Looking to run Snort to monitor authentication attempts on external facing devices.

Does anyone have an example of a rule looking at a single IP of a device for monitoring login attempts. The rule would alert for failed and successful logins if detected.

this particular rule https://www.snort.org/rule_docs/1-19559 will fire if more than 5 login attempts are made in 60 seconds, discussed also here:

In my example the login method would be to monitor SSH login attempts on an external facing device, although this is blocked by default it would be good to monitor for attempted logon requests.
