A Web module consists of servlets, JavaServer Pages (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. You 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.
You can use three types of Web login authentication mechanisms to configure a Web application: basic authentication, form-based authentication and client certificate-based authentication. Protect Web resources in a Web application by assigning security roles to those resources.
Security constraints determine how Web content is to be protected.
Use the administrative console to modify the security settings for all applications.
This topic describes how to assign users and groups to roles if you are using WebSphere® Application Server authorization for Java™ Platform, Enterprise Edition (Java EE) roles.
