Why and when to perform this task
You can decide whether to enable IBM WebSphere Application Server security. You must enable global security for all other security settings to function.
WebSphere Application Server uses cryptography to protect sensitive data and to ensure confidentiality and integrity of communications between WebSphere Application Server and other components in the network. Cryptography is also used by Web services security when certain security constraints are configured for the Web Services application.
WebSphere Application Server uses Java Secure Sockets Extension (JSSE) and Java Cryptography Extension (JCE) libraries in the Software Development Kit (SDK) to perform this cryptography. The SDK provides strong but limited jurisdiction policy files. Unrestricted policy files provide the ability to perform full strength cryptography and to improve performance.
The Unrestricted JCE Policy files for SDK 1.4 Web site is displayed.
Steps for this task
