> We should disable SSLv3 in HttpFS to protect against the POODLEbleed vulnerability.
> See [CVE-2014-3566|http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566]
> We have {{sslProtocol="TLS"}} set to only allow TLS in ssl-server.xml, but when I checked,
I could still connect with SSLv3.  There documentation is somewhat unclear in the tomcat configs
between {{sslProtocol}}, {{sslProtocols}}, and {{sslEnabledProtocols}} and what each value
they take does exactly.  From what I can gather, {{sslProtocol="TLS"}} actually includes SSLv3
and the only way to fix this is to explicitly list which TLS versions we support.
