Security History - Same Entry At Least 20 Times

Hi,

 

Security History is showing the following entry over and over again every minute starting today at 5:55:27 PM with the latest entry (so far) at 5:57:11):

 

Unauthorized Access Blocked (Open Process Token)

 

All of the entries have been blocked by NIS 2012.  What might be going on?

 

Thanks,

Cody
