Workarounds and Mitigations

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.

To disable the SSLv3 protocol in the Tomcat shipped as part of Algo Credit Limits, edit $JLIB_CONFIG_DIR/apps/tomcat/cfg/conf/server.xml. Find the SSL connector and add the following two lines after the SSLEnabled=“true” line:

sslProtocol=“TLS”
sslEnabledProtocols=“TLSv1.2,TLSv1.1,TLSv1”
