== Encrypting Communications
|
|
|
|
Elasticsearch nodes store data that may be confidential. Attacks on the data may
|
|
come from the network. These attacks could include sniffing of the data,
|
|
manipulation of the data, and attempts to gain access to the server and thus the
|
|
files storing the data. Securing your nodes is required in order to use a production
|
|
license that enables {security} and helps reduce the risk from network-based attacks.
|
|
|
|
This section shows how to:
|
|
|
|
* Encrypt traffic to, from and within an Elasticsearch cluster using SSL/TLS,
|
|
* Require nodes to authenticate as they join the cluster using SSL certificates, and
|
|
* Make it more difficult for remote attackers to issue any commands to Elasticsearch.
|
|
|
|
The authentication of new nodes helps prevent a rogue node from joining the
|
|
cluster and receiving data through replication.
