how to detect when a user granted the access on a site?

Question

I have a scenario in which the farm administrators as well as the site collection administrator are not the administrator of a sub site.

Is there a solution to detect when these farm or site collection administrators grant access for a certain user on this site and then notify the real site administrator?

Thank you.

In order to achieve this you have to write custom code. SharePoint 2013 introduced a new event receiver class called "SPSecurityEventReceiver".

The custom event receiver class must derive from SPSecurityEventReceiver

Another way would be to develop a timer job which reads the audit log for the site to determine which groups have been updated, then fire a workflow or code from that.
