>                 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.
