#### To set listener security properties

This procedure applies to HTTP listener, IIOP listener, and JMX Connector security properties.

1. In the Edit HTTP Listener, Edit IIOP Listener, or Edit JMX Connector page, go to the section labeled SSL.

2. Check the Enabled box in the Security field to enable security for this listener.

   When this option is selected, you must select SSL3 or TLS to specify which type of security is enabled, and you must enter a certificate nickname.

3. Check the Enabled box in the Client Authentication field if clients are to authenticate themselves to the Application Server when using this listener.

4. Enter the keystore alias in the Certificate Nickname field if the Enabled box is checked.

   The keystore alias is a single value that identifies an existing server key pair and certificate. The certificate nickname for the default keystore is `s1as`.

   To find the Certificate Nickname, use `keytool`, as shown in the following example:`keytool -list -v -keystore keystore.jks.`

   If the name has changed in the keystore file, then use that name instead of `keystore.jks`.

   To find the Certificate Nickname, use the `certutil` utility.

5. Select SSL3 and/or TLS if the Enabled box is checked. By default, both SSL3 and TLS are enabled.

6. Enable individual cipher suites, if needed. By default, all supported cipher suites are enabled.

   For information on ciphers, see "About Ciphers" in Sun Java System Application Server 9.1 Administration Guide.

7. Select Save to save the changes or Load Defaults to cancel.
