EJB elements operate inside a container environment and rely heavily on the container to give security. The four key services needed for the security are:
1. Identification: In Java security APIs this identifier is define as a principal.
2. Authentication: To show the identity one must present the credentials in the form of password, digital certificate, swipe card, finger prints etc.
3. Authorization (Access Control): Every secured system should limit access to particular users. The common route to enforce access control is by maintaining security privileges and roles.
4. Data Confidentiality: This is performed by encryption of some sort. It is no good to shield your data by authentication if someone may read the password.
