/**
* Interceptor that handles security aspects after the security checks
* have been made. Example: setting the principal on the EnterpriseContext
*
* This interceptor is needed because the security interceptor happens after
* the instance interceptor in the case of SFSB due to the reason that
* security exceptions need to invalidate the session.
*
* Note: This interceptor has to follow the SFSB instance interceptor in the
* call path as it obtains the enterprise context from the invocation
*
