Solution 1

If the user does not require direct access to the Security field, hide it from the user.
To do this, deny Read access to the following item from the Master database: 
/sitecore/templates/System/Templates/Sections/Security/Security/__Security

If the user does require direct access to the Security field, allow Read access to the following item from the Core database:
