Create new multiple security domains

We can create multiple security domains in the configuration. By creating multiple security domains, you can configure different security attributes for administrative and user applications within a cell environment.

Only users assigned to the administrator role can create new multiple security domains. Enable global security in the environment before creating new multiple security domains.

Read about Multiple security domains for a better understanding of what multiple security domains are and how they are supported in this version of WAS.

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:

Create a new security domain using the admin console:


Procedure

  1. Click Security > Security domains.

  2. On the Security domains collection page, click New.

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

  4. Specify a unique description for the domain. After you click Apply you are returned to the Security domains detail page

  5. 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.
  6. Customize the security configuration by specifying security attributes for your 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. We can 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 you 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, you 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 you to configure the user registry for the security domain. We can separately configure any registry used at the domain level. Read about Multiple security domains for more information.

    Trust association

    When you 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 your needs. Only configure those interceptors that are to be used at the domain level.

    SPNEGO Web Authentication

    The SPNEGO web authentication, which enables you 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 v7.0. 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 you 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 that need 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. We can 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 specify a login used exclusively by the applications in the security domain.

    JAAS system logins

    Configuration settings for the JAAS system logins. We can 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 specify a login used exclusively by the applications in the security domain.

    For both JAAS application logins and JAAS system logins, the collections are not populated until one is created first. We can do this by selecting customize for this domain under JAAS application logins or JAAS system logins and then by selecting Apply or OK.

    JAAS J2C authentication

    Configuration settings for the JAAS J2C authentication data. We can 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 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. We can 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

    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 that is 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. Tivoli 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.

    On z/OS, you can enable or disable the System Authorization Facility (SAF) based authorization at the domain level.

    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.

  7. Click Apply.

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