Web component security
A web module consists of servlets, JSP files, server-side utility classes, static web content, which includes HTML, images, sound files, cascading style sheets (CSS), and client-side classes or applets. We can use development tools such as Rational Application Developer to develop a web module and enforce security at the method level of each web resource.
We can identify a web resource by its URI pattern. A web resource method can be any HTTP method (GET, POST, DELETE, PUT, for example). We can group a set of URI patterns and a set of HTTP methods together and assign this grouping a set of roles. When a web resource method is secured by associating a set of roles, grant a user at least one role in that set to access that method. We can exclude anyone from accessing a set of web resources by assigning an empty set of roles. A servlet or a JSP file can run as different identities before invoking another enterprise bean component. All the secured web resources require the user to log in by using a configured login mechanism. Three types of web login authentication mechanisms are available: basic authentication, form-based authentication and client certificate-based authentication.
In WAS v6.1, a portlet resource that is part of a web module can also be protected when it is accessed directly through URL. The protection is similar to other web based resources. See Portlet URL security.
