---------------------------------
Summary: Secure ZooKeeper should be easy and the default
Key: SOLR-7889
URL: https://issues.apache.org/jira/browse/SOLR-7889
Project: Solr
Issue Type: Improvement
Components: security
Reporter: Jan Høydahl
Priority: Critical
Fix For: Trunk, 5.4
ZooKeeper security is documented at
https://cwiki.apache.org/confluence/display/solr/ZooKeeper+Access+Control but
is not trivial to setup, see http://search-lucene.com/m/eHNlqr6EnMrP6O
As we enable more and more security stuff, securing ZK should be easier to do
and ideally the default.
The {{DefaultZkACLProvider}} should by default require admin access for all
operations including read of {{/security.json}}, and other sensitive paths.
Today this is left to the user to implement.
Move manual env-var instructions from documentation into start scripts, with
defaults for read-only and admin user passwords.
Perhaps even Solr should refuse to start if ZK communication is not ACL
protected, encrypted and if default admin passwd is not changed. Overrideable
with a new option {{bin/solr start --insecure}}
Let this JIRA be an umbrella for several child tasks.
