Copy multiple security domains

We can copy selected multiple security domains from the domain collection to create a new domain. This is useful to create a domain that is similar to a previous domain. However, we might want to make a few slight adjustments. When copying an existing domain, supply a unique domain name for the new one. Only users assigned to the administrator role can copy or create new multiple security domains. Enable global security in the environment before copying multiple security domains. Security domains provide a mechanism to use different security settings for administrative applications and user applications. They also provide the ability to support multiple security settings so different applications can use different security attributes like user registry or login configurations.

Use multiple security domains to achieve the following goals:

• Configure different security attributes for administrative and user applications within a cell
• Consolidate server configurations by managing different security configurations within a cell
• Restrict access between applications with different user registries, or configure trust relationships between applications to support communication across registries

Copy an existing security domain

1. Click...
   Security > Security domains

2. Optional: From Preferences, we can select the maximum number of rows to display when the domain collection is large. The default number of rows is 20. Rows that exceed that number appear on subsequent pages.

3. Select a domain to copy.

4. Click Copy Selected Domain... to copy an existing domain from the collection. We can optionally select Copy Global Security.. to copy an existing domain and have it maintain its global security settings (collection selections are ignored). A new domain name is also required if we choose this option.

5. Specify a unique name for the domain. This field is required. A domain name must be unique within a cell and cannot contain an invalid character.

6. Specify a unique description for the domain.

7. Click Apply. After clicking Apply we are returned to the Security domains detail page

8. Under Assigned Scopes, assign the security domain to the entire cell or select the specific servers, clusters, and service integration buses to include in the security domain.

9. Customize the security configuration by specifying security attributes for our new domain and by assigning it to cell resources.

   We can change security attributes such as the following:

   Application Security

   Settings for application security and Java 2 security. Use the global security settings or customize the settings for a domain.

   Select Enable application security to enable or disable security this choice for user applications. When this selection is disabled, all of the EJBs and web applications in the security domain are no longer protected. Access is granted to these resources without user authentication. When we enable this selection, the J2EE security is enforced for all of the EJBs and web applications in the security domain. The J2EE security is only enforced when Global Security is enabled in the global security configuration, (that is, we cannot enable application security without first enabling Global Security at the global level).

   Java 2 Security

   Select Java 2 security to enable or disable Java 2 security at the domain level. This choice enables or disables Java 2 security at the process (JVM) level so that all applications (both administrative and user) can enable or disable Java 2 security.

   User realm

   This section enables us to configure the user registry for the security domain. We can separately configure any registry used at the domain level.

   Trust association

   When we configure the trust association interceptor (TAI) at a domain level, the interceptors configured at the global level are copied to the domain level for convenience. We can modify the interceptor list at the domain level to fit our needs. Only configure those interceptors that are to be used at the domain level.

   SPNEGO Web Authentication

   The SPNEGO web authentication, which enables us to configure SPNEGO for web resource authentication, can be configured at the domain level.

   In WAS v6.1, a TAI that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) to securely negotiate and authenticate HTTP requests for secured resources was introduced. This function was deprecated in WAS 7.0. SPNEGO web authentication has taken its place to provide dynamic reload of the SPNEGO filters and to enable fallback to the application login method.

   RMI/IIOP Security

   The RMI/IIOP security attribute refers to the CSIv2 (Common Secure Interoperability version 2) protocol properties. When we configure these attributes at the domain level, the RMI/IIOP security configuration at the global level is copied for convenience.

   We can change the attributes to be different at the domain level. The Transport layer settings for CSIv2 inbound communications should be the same for both the global and the domain levels. If they are different, the domain level attributes are applied to all of the application in the process.

   JAAS application logins

   Configuration settings for the JAAS application logins. Use the global security settings or customize the settings for a domain.

   The JAAS application logins, the JAAS system logins, and the JAAS J2C authentication data aliases can all be configured at the domain level. Be default, all of the applications in the system have access to the JAAS logins configured at the global level. The security runtime first checks for the JAAS logins at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure any of these JAAS logins at a domain only when we need to specify a login used exclusively by the applications in the security domain.

   JAAS system logins

   Configuration settings for the JAAS system logins. Use the global security settings or customize the configuration settings for a domain.

   The JAAS application logins, the JAAS system logins, and the JAAS J2C authentication data aliases can all be configured at the domain level. Be default, all of the applications in the system have access to the JAAS logins configured at the global level. The security runtime first checks for the JAAS logins at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure any of these JAAS logins at a domain only when we need to specify a login used exclusively by the applications in the security domain.

   JAAS J2C authentication

   Configuration settings for the JAAS J2C authentication data. Use the global security settings or customize the settings for a domain.

   The JAAS application logins, the JAAS system logins, and the JAAS J2C authentication data aliases can all be configured at the domain level. Be default, all of the applications in the system have access to the JAAS logins configured at the global level. The security runtime first checks for the JAAS logins at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure any of these JAAS logins at a domain only when we need to specify a login used exclusively by the applications in the security domain.

   Java Authentication SPI (JASPI)

   Configuration settings for a Java Authentication SPI (JASPI) authentication provider. Use the global security settings or customize the settings for a domain. To configure JASPI authentication providers for a domain, select Customize for this domain and then enable JASPI. Select Providers to define providers for the domain.

   The JASPI authentication provider can be enabled with providers configured at the domain level. By default, all of the applications in the system have access to the JASPI authentication providers configured at the global level. The security runtime first checks for the JASPI authentication providers at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure JASPI authentication providers at a domain only when the provider is to be used exclusively by the applications in that security domain.

   Authentication Mechanism Attributes

   The various cache settings that need to applied at the domain level.

   Select Authentication cache settings to specify your authentication cache settings. The configuration specified on this panel is applied only to this domain.

   Select LTPA Timeout to configure a different LTPA timeout value at the domain level. The default timeout value is 120 minutes, which is set at the global level. If the LTPA timeout is set at the domain level, any token created in the security domain when accessing user applications is created with this expiration time.

   When Use realm-qualified user names is enabled, user names returned by methods such as getUserPrincipal( ) are qualified with the security realm (user registry) used by applications in the security domain.

   Authorization Provider

   We can configure an external third party JACC (Java Authorization Contract for Containers) provider at the domain level. Security Access Manager's JACC provider can only be configured at the global level. Security domains can still use it if they do not override the authorization provider with another JACC provider or with the built-in native authorization.

   Custom properties

   Set custom properties at the domain level that are either new or different from those at the global level. By default, all of the custom properties at the global security configuration can be accessed by all of the applications in the cell. The security runtime code first checks for the custom property at the domain level. If it does not find it, it then attempts to obtain the custom property from the global security configuration.

   Click Apply.

   After we have saved the configuration changes, restart the server for our changes to take effect.
