Configure users and roles

uses the access control system integrated with the Splunk platform. The Splunk platform authorization allows you to add users, assign users to roles, and assign those roles custom capabilities to provide granular, role-based access control for your organization.

Authentication methods

The Splunk platform supports several methods of user authentication. Splunk platform built-in user authentication takes precedence over any configured external authentication. See About user authentication in Securing Splunk Enterprise.

Configuring user roles

adds three roles to the default roles provided by Splunk platform. The new roles allow a Splunk administrator to assign access to specific functions in ES based on a user's access requirements. The Splunk platform administrator can assign groups of users to the roles that best fit the tasks the users will perform and manage in . There are three categories of users.

User Description Splunk ES role
Security Director Seeks to understand the current security posture of the organization by reviewing primarily the Security Posture, Protection Centers, and Audit dashboards. A security director does not configure the product or manage incidents. ess_user
Security Analyst Uses the Security Posture and Incident Review dashboards to manage and investigate security incidents. Security Analysts are also responsible for reviewing the Protection Centers and providing direction on what constitutes a security incident. They also define the thresholds used by correlation searches and dashboards. A Security Analyst needs to be able to edit correlation searches and create suppressions. ess_analyst
Solution Administrator Installs and maintains Splunk platform installations and Splunk Apps. This user is responsible for configuring workflows, adding new data sources, and tuning and troubleshooting the application. admin or sc_admin

Each custom role inherits from Splunk platform roles and adds capabilities specific to Splunk ES. Not all of the three roles custom to Splunk ES can be assigned to users.

Splunk ES role Inherits from Splunk platform role Added Splunk ES capabilities Can be assigned to users
ess_user user real-time search Yes. Replaces the user role for ES users.
ess_analyst user, ess_user, power Inherits ess_user and adds: create, edit, and own notable events and perform all transitions Yes. Replaces the power role for ES users.
ess_admin user, ess_user, power, ess_analyst inherits ess_analyst and adds: edit correlation searches and edit review statuses No. You must use a Splunk platform admin role to administer an Enterprise Security installation.

The Splunk platform admin role inherits all unique ES capabilities. In a Splunk Cloud deployment, the Splunk platform admin role is named sc_admin. Use the admin or sc_admin role to administer an Enterprise Security installation.

Splunk platform role Inherits from role Added capabilities Accepts user assignment
admin user, ess_user, power, ess_analyst, ess_admin All Yes.
sc_admin user, ess_user, power, ess_analyst, ess_admin All Yes.

Role inheritance

All role inheritance is preconfigured in Enterprise Security. If the capabilities of any role are changed, other inheriting roles will receive the changes. For more information about roles, see Add and edit roles and Securing Splunk in Securing Splunk Enterprise.

Add capabilities to a role

Capabilities control the level of access that roles have to various features in Splunk Enterprise Security. Use the Permissions page in Enterprise Security to review and change the capabilities assigned to a role.

  1. On the menu bar, select Configure > General > Permissions.
  2. Find the role you want to update.
  3. Find the ES Component you want to add.
  4. Select the check box for the component for the role.
  5. Save.

Capabilities specific to

uses custom capabilities to control access to ES-specific features.

Add capabilities on the permissions page in to make sure that the proper access control lists (ACLs) are updated. The permissions page makes the ACL changes for you. If you add these custom capabilities on the Splunk platform settings page, you must update the ACLs yourself.

Adjust the concurrent searches for a role

Splunk platform defines a limit on concurrently running searches for the user and power roles by default. You may want to change those concurrent searches for some roles.

  1. On the menu bar, select Configure > General > General Settings.
  2. Review the limits for roles and change them as desired.
Item Description
Search Disk Quota (admin) The maximum disk space (MB) a user with the admin role can use to store search job results.
Search Jobs Quota (admin) The maximum number of concurrent searches for users with the admin role.
Search Jobs Quota (power) The maximum number of concurrent searches for users with the power role.

To change the limits for roles other then admin and power, edit the authorize.conf file to update the default search quota. See the authorize.conf.example in the Admin manual.

Configure the roles to search multiple indexes

Splunk platform stores ingested data sources in multiple indexes. Distributing data into multiple indexes allows you to use role-based access control and vary retention policies for data sources. Splunk platform configures all roles to search only the main index by default. See About configuring role-based user access

To allow roles in to search additional indexes, assign the indexes that contain relevant security data to the relevant roles.

  1. Select Settings > Access Controls.
  2. Click Roles.
  3. Click the role name that you want to allow to search additional indexes.
  4. Select the desired Indexes searched by default and Indexes that this role can search. Do not include summary indexes, as this can cause a search and summary index loop.
  5. Save your changes.
  6. Repeat for additional roles as needed.

If you do not update the roles with the correct indexes, searches and other knowledge objects that rely on data from unassigned indexes will not update or display results.

For more information on the reasons for multiple indexes, see Why have multiple indexes? in Managing Indexers and Clusters of Indexers.
