Workarounds and Mitigations
First make sure to Quiesce all domains and services to stop traffic to the appliance. System quiesce and unquiesce commands can be invoked by navigating to Administration --> Main --> System Control.
Next, select Objects --> Crypto Configuration --> Crypto Profile in the left navigation pane. For all the crypto profile objects that are configured, in the "Configure Crypto Profile" page, "Options" parameter, select the checkbox "Disable SSL version 3". Click Apply.
Note that SSL v3 must be disabled in all the Crypto Profile objects configured in all the domains.
To disable SSLv3 in Web Management and XML Management interfaces, refer to Disable SSLv3 in DataPower Web management and XML management services.
If you have configured WebSphere JMS objects, refer to Disable SSLv3 in DataPower WebSphere Java Message Service (JMS) objects.
IBM recommends that you review your entire environment to identify other areas that enable the SSLv3 protocol and take appropriate mitigation such as disabling SSLv3 and remediation actions.
