Encrypting Sensitive Data in Watcher
editEncrypting Sensitive Data in Watcher
editWatches might have access to sensitive data such as HTTP basic authentication information or details about your SMTP email service. You can encrypt this data by generating a key and adding some secure settings on each node in your cluster.
To encrypt sensitive data in Watcher:
- Use the syskeygen command to create a system key file.
-
Copy the
system_key
file to all of the nodes in your cluster.The system key is a symmetric key, so the same key must be used on every node in the cluster.
-
Set the
xpack.watcher.encrypt_sensitive_data
setting:xpack.watcher.encrypt_sensitive_data: true
-
Set the
xpack.watcher.encryption_key
setting in the Elasticsearch keystore on each node in the cluster.For example, run the following command to import the
system_key
file on each node:bin/elasticsearch-keystore add-file xpack.watcher.encryption_key <filepath>/system_key
-
Delete the
system_key
file on each node in the cluster.
Existing watches are not affected by these changes. Only watches that you create after following these steps have encryption enabled.
