How to search failed login attempts of a user in Siteminder smaccess.log and alert after the 3rd unsuccessful login attempt?

Path Finder

Need to develop a dashboard and a report for getting the the user information of who tried to log in and failed. Need to get an alert after the 3rd unsuccessful login attempt.

Thanks.

The following search will give you a list of user names (CN) that have more than 2 failed logins.

sourcetype=yoursourcetype  AuthReject
| stats count by CN
| where CN > 2

If you save this search as an alert, you can set the trigger condition to "number of results greater than zero".
You will need to identify the time range though: "number of failed login attempts in the last hour" is a very different thing than "number of failed login attempts in the past week."

Instead of hoping that someone in the community knows Siteminder, you could post a small portion of the log (with things like user names obfuscated). This would let many members answer your question...

Also it would be helpful to know what you used as a sourcetype, and the necessary field names.
