Web services: Default bindings for the Web services security collection
Use this page to configure the settings for nonce on the server level and to manage the default bindings for the signing information, encryption information, key information, token generators, token consumers, key locators, collection certificate store, trust anchors, trusted ID evaluators, algorithm mappings, and login mappings. Important distinction between V5.x and v6.x applications
Note: The information in this article supports v5.x applications only that are used with WAS v6.x. The information does not apply to v6.0.x applications.
To view this administrative console page for the server level, complete the following steps:
- Click Servers > Application Servers > servername.
- Under Security, click Web services: Default bindings for Web services security.
Read the Web services documentation before you begin defining the default bindings for Web services security.
Nonce is a unique cryptographic number that is embedded in a message to help stop repeat, unauthorized attacks of user name tokens. In WAS and WAS Express, specify values for the Nonce cache timeout, Nonce maximum age, and Nonce clock skew fields for the server-level.
The default binding configuration provides a central location where reusable binding information is defined. The application binding file can reference the information that is contained in the default binding configuration.
- Nonce cache timeout
Specifies the timeout value, in seconds, for the nonce cached on the server. Nonce is a randomly generated value.
The Nonce cache timeout field is not required on the server level, but it is required on the cell level. To specify a value for the field on the cell level, click Security > Web services.
If you make changes to the value for the Nonce cache timeout field, you must restart WAS for the changes to take effect.
Default 600 seconds Minimum 300 seconds - Nonce maximum age
Default time, in seconds, before the nonce timestamp expires. Nonce is a randomly generated value.
The maximum value cannot exceed the number of seconds that is specified in the Nonce cache timeout field for the server level.
The Nonce maximum age field is not required on the server level, but it is required on the cell level. The value set for this Nonce maximum age field on the server level must not exceed the value for the Nonce maximum age field on the cell level. To specify a value for the Nonce maximum age field on the cell level, click Security > Web services.
Default 300 seconds Range 300 to the value that is specified, in seconds, in the Nonce cache timeout field. - Nonce clock skew
Default clock skew value, in seconds, to consider when WAS checks the timeliness of the message. Nonce is a randomly generated value.
The maximum value cannot exceed the number of seconds that is specified in the Nonce maximum age field.
The Nonce clock skew field is not required on the server level, but it is required on the cell level. To specify a value for the Nonce clock skew field on the cell level, click Security > Web services.
Default 0 seconds Range 0 to the value that is specified, in seconds, in the Nonce maximum age field. - Distribute nonce caching
Enables distributed caching for the nonce value using a Data Replication Service (DRS).
In previous releases of WebSphere Application Server, the nonce value cached locally. By selecting this option, the nonce value is propagated to other servers in your environment. However, the nonce value might be subject to a one-second delay in propagation and subject to any network congestion.
