Lars Francke resolved AMBARI-20893.
-----------------------------------
Resolution: Duplicate
> 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.
