If you are using SP 2013, you can SPSecurityEventReceiver. A good resource on this is: http://www.timferro.com/wordpress/archives/737.

Excerpts:

[This Server Side and Remote Event Receiver] Provides methods [in 5 main categories: 1. Group Events, 2. User Events, 3. Inheritance Events, 4. Role Assignment Events, and 5. Role Definition Events] to trap events [Adding/Added/Updating/Updated/Deleting/Deleted/Breaking/Broken/Reset/Resetting] that are raised [at the Site Collection or Site level] for security.
