Role-based gain access to control in Amazon OpenSearch Service through SAML combination with AWS IAM Identity Center

Amazon OpenSearch Service is a handled service that makes it easy to protect, release, and run OpenSearch clusters at scale in the AWS Cloud. AWS IAM Identity Center (follower to AWS Single Sign-On) assists you firmly produce or link your labor force identities and handle their gain access to centrally throughout AWS accounts and applications. To construct a strong least-privilege security posture, clients likewise desired fine-grained gain access to control to handle control panel approval by user function. In this post, we show a detailed treatment to execute IAM Identity Center to OpenSearch Service through native SAML combination, and set up role-based gain access to control in OpenSearch Dashboards by utilizing group qualities in IAM Identity Center. You can follow the actions in this post to accomplish both authentication and permission for OpenSearch Service based upon the groups set up in IAM Identity Center.

Service introduction

Let’s evaluation how to map users and groups in IAM Identity Center to OpenSearch Service security functions. Backend functions in OpenSearch Service are utilized to map external identities or qualities of workgroups to pre-defined OpenSearch Service security functions.

The following diagram reveals the service architecture. Produce 2 groups, designate a user to each group and modify characteristic mappings in IAM Identity Center. If you have actually incorporated IAM Identity Center with your Identity Service Provider (IdP), you can utilize existing users and groups mapped to your IdP for this test. The service utilizes 2 functions: all_access for administrators, and alerting_full_access for designers who are just enabled to handle OpenSearch Service notifies. You can establish backend function mapping in OpenSearch Dashboards by group ID. Based upon the following diagram, you can map the function all_access to the group Admin, and alerting_full_access to Designer User janedoe remains in the group Admin, and user johnstiles remains in the group Designer

Then you will visit as each user to confirm the gain access to control by taking a look at the various control panel views.

Let’s get going!

Requirements

Total the following requirement actions:

Have an AWS account.
Have an Amazon OpenSearch Service domain.
Enable IAM Identity Center in the exact same Area as the OpenSearch Service domain.
Evaluate your users in IAM Identity Center (to produce users, describe Include users).

Enable SAML in Amazon OpenSearch Service and copy SAML specifications

To set up SAML in OpenSearch Service, total the following actions:

On the OpenSearch Service console, pick Domains in the navigation pane.
Select your domain.
On the Security setup tab, validate that Fine-grained gain access to control is made it possible for.
On the Actions menu, pick Edit security setup
Select Enable SAML authentication

You can likewise set up SAML throughout domain production if you are developing a brand-new OpenSearch domain. To find out more, describe SAML authentication for OpenSearch Dashboards

Copy the worths for Provider entity ID and IdP-Initiated SSO URL

Produce a SAML application in IAM Identity Center

To produce a SAML application in IAM Identity Center, total the following actions:

On the IAM Identity Center console, pick Applications in the navigation pane.
Select Include application
Select Include consumer SAML 2.0 application, then pick Next
Enter your application name for Show name
Under IAM Identity Center metadata, pick Download to download the SAML metadata file.
Under Application metadata, choose By hand type your metadata worths
For Application Air Conditioning URL, go into the IdP-initiated URL you copied previously.
For Application SAML audience, go into the company entity ID you copied previously.
Select Submit
On the Actions menu, pick Edit characteristic mappings
Produce qualities and map the following worths:
1. Topic map to $ {user: e-mail} , the format is emailAddress.
2. Function map to $ {user: groups} , the format is undefined.
Select Conserve modifications
On the IAM Identity Center console, pick Groups in the navigation pane.
Produce 2 groups: Designer and Admin.
Appoint user janedoe to the group Admin.
Appoint user johnstiles to the group Designer.
Open the Admin group and copy the group ID.

Complete SAML setup and map the SAML main backend function

To finish your SAML setup and map the SAML main backend function, finish the following actions:

On the OpenSearch Service console, pick Domains in the navigation pane.
Open your domain and pick Edit security setup
Under SAML authentication for OpenSearch Dashboards/Kibana, for Import IdP metadata, pick Import from XML file
Submit the IdP metadata downloaded from the IAM Identity Center metadata file.

The IdP entity ID will be automobile inhabited.

Under SAML master backend function, go into the group ID of the Admin group you copied previously.
For Functions essential, go into Function for the SAML assertion.

This is due to the fact that we specified and mapped Function to $ {user: groups} as a SAML characteristic in IAM Identity Center.

Select Conserve modifications

Configure backend function mapping for the Designer group

You have actually totally incorporated IAM Identity Center with OpenSearch Service and mapped the Admin group as the main function (all_access) in OpenSearch Service. Now you will visit to OpenSearch Dashboards as Admin and set up mapping for the Designer group.

There are 2 methods to visit to OpenSearch Dashboards:

OpenSearch Dashboards URL— On the OpenSearch Service console, browse to your domain and pick the Dashboards URL under General Info (For instance, https://opensearch-domain-name-random-keys.us-west-2.es.amazonaws.com/_dashboards)
AWS gain access to portal URL— On the IAM Identity Center console, pick Control Panel in the navigation pane and pick the gain access to portal URL under Settings summary (For instance, https://d-1234567abc.awsapps.com/start)

Total the following actions:

Log in as the user in the Admin group ( janedoe).
Select the tile for your OpenSearch Service application to be rerouted to OpenSearch Dashboards.
Select the menu icon, then pick Security, Functions
Select the alerting_full_access function and on the Mapped users tab, pick Manage mapping
For Backend functions, go into the group ID of Designer.
Select Map to use the modification.

Now you have actually effectively mapped the Designer group to the alerting_full_access function in OpenSearch Service.

Confirm authorizations

To confirm authorizations, finish the following actions:

Log out of the Admin account in OpenSearch Service as log in as a Designer user.
Select the OpenSearch Service application tile to be rerouted to OpenSearch Dashboards.

You can see there are just informing associated functions offered on the drop-down menu. This Designer user can’t see all of the Admin functions, such as Security

Tidy Up

After you evaluate the service, keep in mind to erase all of the resources you produced to prevent sustaining future charges:

Erase your Amazon OpenSearch Service domain.
Erase the SAML application, users, and groups in IAM Identity Center.

Conclusion

In the post, we strolled through a service of how to map functions in Amazon OpenSearch Service to groups in IAM Identity Center by utilizing SAML credits to accomplish role-based gain access to control for accessing OpenSearch Dashboards. We linked IAM Identity Center users to OpenSearch Dashboards, and likewise mapped predefined OpenSearch Service security functions to IAM Identity Center groups based upon group qualities. This makes it simpler to handle authorizations without upgrading the mapping when brand-new users coming from the exact same workgroup wish to visit to OpenSearch Dashboards. You can follow the exact same treatment to offer fine-grained access to workgroups based upon group functions or compliance requirements.
