**Problem:** For historical reasons, source files for the Elasticsearch Guide's security, watcher, and Logstash API docs are housed in the `x-pack/docs` directory. This can confuse new contributors who expect Elasticsearch Guide docs to be located in `docs/reference`. **Solution:** - Move the security, watcher, and Logstash API doc source files to the `docs/reference` directory - Update doc snippet tests to use security Rel: https://github.com/elastic/platform-docs-team/issues/208

==== Pre-processing documents to add security details
|
|
|
|
// If an index is shared by many small users it makes sense to put all these users
|
|
// into the same index. Having a dedicated index or shard per user is wasteful.
|
|
// TBD: It's unclear why we're putting users in an index here.
|
|
|
|
To guarantee that a user reads only their own documents, it makes sense to set up
|
|
document level security. In this scenario, each document must have the username
|
|
or role name associated with it, so that this information can be used by the
|
|
role query for document level security. This is a situation where the
|
|
<<ingest-node-set-security-user-processor,set security user processor>> ingest processor can help.
|
|
|
|
NOTE: Document level security doesn't apply to write APIs. You must use unique
|
|
ids for each user that uses the same data stream or index, otherwise they might overwrite other
|
|
users' documents. The ingest processor just adds properties for the current
|
|
authenticated user to the documents that are being indexed.
|
|
|
|
The <<ingest-node-set-security-user-processor,set security user processor>> attaches user-related details (such as
|
|
`username`, `roles`, `email`, `full_name` and `metadata` ) from the current
|
|
authenticated user to the current document by pre-processing the ingest. When
|
|
you index data with an ingest pipeline, user details are automatically attached
|
|
to the document. If the authenticating credential is an API key, the API key
|
|
`id`, `name` and `metadata` (if it exists and is non-empty) are also attached to
|
|
the document.
