Connectors security

edit

This document describes security considerations for native connectors and connector clients. For Workplace Search connectors, see the Workplace Search documentation.

Elastic Cloud deployments have strong security defaults. For example, data is encrypted by default, whether at rest or in transit.

Self-managed deployments require more upfront work to ensure strong security. Refer to Secure the Elastic Stack in the Elasticsearch documentation for more information.

Access to credentials

edit

Credentials for the data source — such as API keys or username/password pair— are stored in your deployment’s .elastic-connectors Elasticsearch index. Therefore, the credentials are visible to all Elastic users with the read indices privilege for that index. By default, the following Elastic users have this privilege: the elastic superuser and the kibana_system user. Enterprise Search service account tokens can also read the .elastic-connectors index.

Access to documents

edit

Data synced from your data source are stored as documents in the Elasticsearch index you created. This data is visible to all Elastic users with the read indices privilege for that index. Be careful to ensure that access to this index is at least as restrictive as access to the original data source.

Encryption

edit

Elastic Cloud automatically encrypts data at rest. Data in transit is automatically encrypted using https.

Self-managed deployments must implement encryption at rest. See Configure security for the Elastic Stack in the Elasticsearch documentation for more information.
