Field security level Kibana

Elastic Stack Kibana
1

Hi,

I'm trying to set up field security level, but it doesn't seem to work.

I'm using the Elastic cloud trial (Deployment version v7.6.0) and the Flights dataset that comes as a demo.

I've created a role (flight_data) with read privileges, and a user (flight-user) with that role.
Then, I went to the Dev Tools and tried the following configuration following the documentation (https://www.elastic.co/guide/en/elasticsearch/reference/current/field-level-security.html)

The idea is to create a role that can only see the data when the OriginCityName of the flights is "London"

POST /_security/role/flight-data
{
"run_as": [ "flight-user" ],
"cluster": [ "monitor" ],
"indices": [
{
"names": [ "kibana_sample_data_flights" ],
"privileges": [ "read" ],
"field_security" : {
"grant" : [ "*" ]
},
"query": "{"match": {"OriginCityName": "London"}}"
}
]
}

However, that user can see all the data. So, what am I missing?

Thanks

What you want is document level security, to do that you need to create a new role like the one below that restricts read only to documents from EZE airport. Then you can assign that role to a new user.

POST /_security/role/eze-read
{
  "indices": [
    {
      "names": [
        "kibana_sample_data_flights"
      ],
      "privileges": [
        "read"
      ],
      "query": {
        "template": {
          "source": {
            "term": {
              "OriginAirportID": "EZE"
            }
          }
        }
      }
    }
  ]
}

If the user is called eze you can run this and see how the count is just 258:

$ curl -u "eze:changeme" "localhost:9200/kibana_sample*/_count" 
{"count":258,"_shards":{"total":1,"successful":1,"skipped":0,"failed":0}}

While if you do the same using the super user you get all the docs 13059:

$ curl -u "elastic:changeme" "localhost:9200/kibana_sample*/_count" 
{"count":13059,"_shards":{"total":1,"successful":1,"skipped":0,"failed":0}}

Let us know if this is what you need. Best.
