=== Encrypting Communications in {es}
|
|
|
|
|
|
|
|
|
|
{security} enables you to encrypt traffic to, from, and within your {es} cluster.
|
|
|
|
|
Connections are secured using Transport Layer Security (TLS/SSL).
|
|
|
|
|
|
|
|
|
|
WARNING: Clusters that do not have encryption enabled send all data in plain text
|
|
|
|
|
including passwords and will not be able to install a license that enables {security}.
|
|
|
|
|
|
|
|
|
|
To enable encryption, you need to perform the following steps on each node in
|
|
|
|
|
the cluster:
|
|
|
|
|
|
|
|
|
|
. <<installing-xpack-es,Install {xpack} into {es}>>.
|
|
|
|
|
|
|
|
|
|
. <<node-certificates, Generate a private key and X.509 certificate>>.
|
|
|
|
|
|

|
|
|
. Configure each node to:
|
|
|
|
|
.. Required: <<tls-transport,Enable TLS on the transport layer>>.
|
|
|
|
|
.. Recommended: <<tls-http,Enable TLS on the HTTP layer>>.
