Controlling access

After creating users and groups, you can assign them access to specific resources, roles, and policies to control what pages, portlets, applications, and information users and groups have access to.

Review the following information and perform the following tasks to control access within WebSphere Portal:

• Manage Access Control

  Get familiar with concepts related to administering WebSphere Portal access control. To administer access control, use the Resource Permissions portlet, the User and Group Permissions portlet, the Manage Users and Groups portlet, the XML configuration interface, or the Portal Scripting Interface.

• Resources, roles, and policies

  Learn about Portal resources, roles, access rights, and initial access control settings.

• Access control scenarios

  These scenarios provide helpful illustrations on how access control can be set up.

• Set user and group permissions

  The User and Group Permissions portlet allows you to view and modify the roles that users and groups have on resources.

• Set resource permissions

  Assign and control access for different types of resources.

• Delegated Access Control Administration

  WebSphere Portal supports delegated access control administration.

• Access Control Caching

  Access Control internally uses several caches to increase access control decision times. You can improve access control performance for special scenarios by setting the lifetime and size properties of these caches in the Cache Manager Service. In most cases, WebSphere Portal will run smoothly with the default cache settings. However, if you have a large number of resources or a large number of customized resources, you may want to change the cache settings to see if you can improve performance.
