-------------------------------------

             Summary: Ambari should disable old/insecure SSL/TLS protocols by default
                 Key: AMBARI-20893
                 URL: https://issues.apache.org/jira/browse/AMBARI-20893
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
            Reporter: Lars Francke
            Priority: Minor


By default these protocols are enabled in Ambari when using SSL/TLS:

* SSL 2
* SSL 3
* TLS 1.0
* TLS 1.1
* TLS 1.2

Yes they can be disabled but a user needs to do that. Both SSL 2 and SSL 3 have been officially deprecated and I think it's really bad that we ship with them enabled by default. TLS 1 is prohibited by PCI standards but has not been officially deprecated I think.

So I propose to change the default value of `security.server.disabled.protocols` to include at least SSL2 & 3.
