I am trying to setup Elastic search log management...
I have enabled Free Xpack secutiry for kibana Dashboard authentication and created users with super access for my team members.. Now I would like to disable elastic user login access in kibana Dashboard..
So elastic user access will work only beat's & Logstash configurations.
How can I disable elastic user kibana Dashboard access?
Read this link. Create a separate user with privileges required to only index data and use them in the output plugin for logstash and beats.

after all the necessary installation for kibana when i tried to do integration to add logs it shows "To use central management for Elastic Agents, enable the following Elasticsearch security features."
when i added xpack security value to true and after restarting the elasticsearch when i'm checking on browser it shows kibna is not ready yet or gives 502 error : service unavailable message: licence is not available
You can use Filebeat to monitor the Elasticsearch log files, collect log events, and ship them to the monitoring cluster.
Your recent logs are visible on the Monitoring page in Kibana.
We are working on a project where we are authenticating users with Azure Active Directory. Upon the successful authentication, the user's browsers receive an Id and Access token, and then we use the same access token to query other Microsoft products (Sharepoint, OneDrive, etc).
We are planning to use Elastic Search for our search need. We have already set up SAML/ OpenId realms on our ECE Deployment Portal and Cluster. So if any users try to access ECE deployment portal/ Kibana, they will be prompted to authenticate against Microsoft Azure AD, and upon successful authentication, they get redirected to ECE or Kibana.
We are using C# and NEST dll (ElasticSearch.Net) to create queries and search the elastic search end point. We are not sure how exactly should we use the access token received on the UI side with Elastic Search to query out indices. We know, we can use native user credentials or API keys to access the elastic search but we want to use the same azure ad authentication flow(SAML/OpenID) to access Elastic Search.
Is it possible to use the Azure AD access token received on the UI side to access & query Elastic Search Clusters or is there any other way to re-authenticate users while they try to access Elastic Search Cluster?
Is there a way to authenticate the users with elastic search end point and generate an access token that can be used to query elastic search further?
In short, we want to re-authenticate users with Elastic Search while querying the data?
var settings = new ConnectionSettings(new Uri(mEsQuerySource.Url));
settings.BasicAuthentication("user", "plain text password");
mClient = new ElasticClient(settings);
Thank You Tim for sharing the solution over elastic Portal. I am updating the same answer over here to help other community member.
In current versions of Elasticsearch (as I write this, 7.14 is the latest version) there is no way to use an Azure AD access token to directly access Elasticsearch.
That is, you cannot have your application authenticate directly to AAD and then use the tokens you receive from AAD as a credential to authenticate to Elasticsearch.
There is no authentication provider in Elasticsearch that works with arbitrary tokens from an external issuer.
You can however do the same thing that ECE and Kibana do and perform SAML or OpenID Connect authentication via Elasticsearch, in order to generate Elasticsearch access & refresh tokens (which are separate from the Azure AD tokens).
There is documentation on how to perform SAML 3 or OIDC 2 authentication to Elasticsearch via a custom application.
The high-level overview would be (I assume SAML here, but OIDC would be similar):
When a user accesses your application they would authenticate against AzureAD as normal
Then, you would use the Elasticsearch APIs to perform an additional authentication against an Elasticsearch SAML realm with Elasticsearch as the service provider and AzureAD as the Identity Provider.
Since the user is already authenticated within Azure AD, that second authentication process should be transparent to the user - AAD will simply issue a new SAML assertion with Elasticsearch as the recipient.
Those Elasticsearch APIs will accept the SAML assertion, and return a pair of tokens (access + refresh) that can be used to authenticate to Elasticsearch
Your application will retain the access + refresh tokens for the user's session
The access token will be used to authenticate when accessing Elasticsearch APIs
The refresh token will be used to generate a new access token when the old one expires (or is about to expire).
If your users are in an identity store that Elasticsearch can query (e.g. something that supports LDAP search), then another option is to use the Elasticsearch run-as capability.
In this case your application would authenticate to Elasticsearch using a single system credential (probably a user in the native realm). That user would have permission to run-as all other users and this can be used to perform searches on behalf of your end users without needing them to authenticate directly to Elasticsearch.
The final option would be to implement a custom realm, if you have engineers who are comfortable writing Java

I am Wroking with ELK Stack 7.x version, Here I am trying to Embed Dashboard to another html page but I am not able to loggin into embedded dashboard since i configured x-pack security plugin.
You should configure the Anonymous access
xpack.security.authc.providers:
anonymous.anonymous1:
order: 0
credentials:
username: "anonymous_service_account"
password: "anonymous_service_account_password"
Anyone with access to the network Kibana is exposed to will be able to
access Kibana. Make sure that you’ve properly restricted the
capabilities of the anonymous service account so that anonymous users
can’t perform destructive actions or escalate their own privileges.
I have Es version 7.6.2 I saw on website that from version 6.2 onwards x-pack is included by default but i was not able to find or enable x-pack for security. how do i enable password protection in Elastic search.
As per elastic search documentation
The first thing you have to do is download the default distribution of
Elasticsearch and Kibana version 6.8+ or 7.1+. Security was added to
the default distribution in 7.1 and 6.8, so if you’re on an older
version, you’ll need to upgrade.
After downloading latest version , you need to enable xpack.security.enabled: true in elasticsearch.yml file
To generate passwords
elasticsearch-setup-passwords auto
in command prompt, your cmd path should be elasticsearch/bin. It will auto generate passwords for elasticsearch kibana etc. note them .
If you want to provide your own username password instead of auto generated execute
elasticsearch-setup-passwords interactive
In kibana.yml update below two with user name and password for elastic search you got by executing set up password
elasticsearch.username: "<elastic>"
elasticsearch.password: "<password>"
Opening kubana it will prompt for username and password, enter password for "kibana" you got from set-up-password
I am able to password protect ES however my kibana is now asking for UID and password when opened. The ES credentials dont work on the kibana screen. What password does Kibana looking for ?
isseue resolved by using elastic user rather than kibana user
Basic username/password authentication for ELK, i was able to achieve using searchguard on windows platform.
Now i am trying to establish secure communication. I have performed the following changes,
In elasticsearch.yml
searchguard.ssl.http.enabled: true
searchguard.ssl.http.keystore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\CN=localhost-keystore.jks
searchguard.ssl.http.keystore_password: 221749a2add117cf889f
searchguard.ssl.http.truststore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\truststore.jks
searchguard.ssl.http.truststore_password: 6d6cf1cc017dc874960b
searchguard.authcz.admin_dn:
- CN=sgadmin
searchguard.ssl.transport.keystore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\CN=localhost-keystore.jks
searchguard.ssl.transport.keystore_password: 221749a2add117cf889f
searchguard.ssl.transport.truststore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\truststore.jks
searchguard.ssl.transport.truststore_password: 6d6cf1cc017dc874960b
In Kibana.yml
elasticsearch.url: "https://localhost:9200"
elasticsearch.username: "admin"
elasticsearch.password: "admin"
If i login to kibana, using http://localhost:5601, it asks for username and password. I dont know what credentails to enter here. i tried admin/admin. Its not working. Before i gave searchguard.ssl.http.... configurations, admin/admin was working fine.
After i added all the searchguard.ssl.http related configuration, the credentails are not working.
I am sure there is some other configuration in kibana.yml w.r.t searchguard configuration. I am not able to find it online. Can any one please help me here on what is missing.
Enabling TLS on the REST layer does not have any impact on user authentication/authorisation. The only difference is:
If you enable TLS on REST layer, only HTTPS access is allowed. You will see an error message if you try to access ES with HTTP
If you disable TLS on REST layer, only HTTP access is allowed. You will see an error message if you try to access ES with HTTPS.
Search Guard will authenticate the credentials against the configured authentication backend in sg_config.yml. If you use the default configuration that ships with Search Guard, it will use the internal user database and the users defined in internal_users.yml. The default "admin" user has full access to all indices and types, so you should be able to use this user to log into Kibana. If you need a user with limited access, the corresponding demo user is "kibanaro". Please refer to internal_users.yml to see all demo users.
Since ES 5.0.2, you need to install the Search Guard Kibana plugin for full authentication and session support. You can find the plugin on the corresponding GitHub repository. You install it like any other Kibana plugin, for example:
bin/kibana-plugin install https://github.com/floragunncom/search-guard-kibana-plugin/releases/download/v5.4.3-3/searchguard-kibana-5.4.3-3.zip
If you do not need advanced stuff like multi-tenancy or JWT Single Sign-on, it should start and work out of the box.
If this does not help, please post the output of your Elasticsearch log files when trying to log in.
