authentication
</p>
<a name="wp88528"> </a><p class="pDefinition">
The process that verifies the identity of a user, device, or other entity in a computer system, usually as a prerequisite to allowing access to resources in a system. The J2EE platform Servlet specification requires three types of authentication: <span style="font-style: italic"><a  href="Glossary.html#wp88542" target="_blank">basic</a></span>, <span style="font-style: italic"><a  href="Glossary.html#wp88786" target="_blank">form-based</a></span>, and <span style="font-style: italic"><a  href="Glossary.html#wp89024" target="_blank">mutual</a></span>, and supports <span style="font-style: italic"><a  href="Glossary.html#wp88675" target="_blank">digest</a></span> authentication.

authorization 
</p>
<a name="wp88534"> </a><p class="pDefinition">
The process by which access to a method or resource is determined. Authorization depends upon the determination of whether the principal associated with a request through authentication is in a given security role. A security role is a logical grouping of users defined by the person who assembles the application. A deployer maps security roles to security identities. Security identities may be principals or groups in the operational environment.

authorization constraint 
</p>
<a name="wp88537"> </a><p class="pDefinition">
An authorization rule that determines who is permitted to access a Web resource collection.
