Remediation/Fixes
WebSphere Business Services Fabric completely relies on WebSphere Application

We recommend that customers install an interim fix for the IBM JDK to disable
SSLv3, for information on the required fix please refer to the the
Remediation/Fixes section in the following bulletin: Security Bulletin:
Vulnerability in SSLv3 affects IBM WebSphere Application Server

IBM recommends that you review your entire environment to identify areas that
enable the SSLv3 protocol and take appropriate mitigation and remediation
actions. The most immediate mitigation action that can be taken is disabling
SSLv3. You should verify disabling SSLv3 does not cause any compatibility
issues.
Workarounds and Mitigations
Customers who cannot or do not want to install the fix recommended in the
"Remediation/Fixes" section of this security bulletin can disable the use of
SSLv3 using manual configuration as described in the "Workarounds and
Mitigations" section in the following bulletin: Security Bulletin:
Vulnerability in SSLv3 affects IBM WebSphere Application Server
