Configure users and roles

The Splunk App for Enterprise Security utilizes the Access Control system of Splunk Enterprise. Splunk Enterprise authentication allows you to add users, assign users to roles, and assign those roles custom capabilities as needed for your organization.

Authentication

Splunk Enterprise supports several methods of user authentication:

• The Splunk Enterprise built-in user authentication system.
• User authentication using LDAP and Active Directory. For more information, see "Set up user authentication with LDAP".
• Scripted authentication API: Use scripted authentication to tie authentication requests to an external authentication system, such as RADIUS or PAM. For more information, see "Set up user authentication with external systems".
• Single Sign-on: For more information, see "About Splunk single sign-on".

Important: The Splunk Enterprise built-in user authentication takes precedence over any configured external authentication.

The Splunk App for Enterprise Security adds three required roles, pre-configured with capabilities. These roles were created to assist in assigning users specific access to functions in the Enterprise Security app. Based upon the information presented below, the admin must assign groups of users to roles that best fit the tasks they will perform and manage within the Enterprise Security app.

Role	Inherits from role	Added capabilities	Accepts user assignment
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: edit 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 Assign users to the "admin" role.
admin	user, ess_user, power, ess_analyst, ess_admin	All	Yes.

Important: The ess_admin role is assigned all ES specific capabilities, but does not inherit Splunk Enterprise admin capabilities. You must use the "admin" role to administer an Enterprise Security installation. To change the capabilities of the ess_user or ess_analyst roles, see "Custom capabilities" in this topic.

Configure user roles

There are three categories of users:

• Security Director: Reviews the Security Posture, Protection Centers, and Audit dashboards in order to understand current Security Posture of the organization. A security director will not configure the product or manage incidents.

• 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 will also define the thresholds used by correlation searches and dashboards. A Security Analyst needs to be able to edit correlation searches and create suppressions.

• Solution Administrator: Installs and maintains Splunk Enterprise and Splunk Apps. This user is responsible for configuring workflows, on-boarding new data sources, and tuning and troubleshooting the application.

Each user type requires different levels of access to perform their assigned functions. The table below shows the user category matched to an Enterprise Security role.

Role	Security Director	Security Analyst	Solution Administrator
ess_user capabilities
ess_analyst capabilities
admin capabilities

Role inheritance

All role inheritance is pre-configured in the Enterprise Security app. If the capabilities of any role are changed, other roles will also inherit the changes. The best method to assess the pre-configured roles, capabilities, and inheritance in the Enterprise Security app is to review the authorize.conf file in $SPLUNK_HOME/etc/apps/SplunkEnterpriseSecuritySuite/default/.

For more information about roles, see the topics "Add and edit roles" and "Securing Splunk" in the Securing Splunk Enterprise Manual.

Custom capabilities

The Enterprise Security app implements new, ES specific features in Splunk Enterprise. To control access to those features, additional capabilities have been created and assigned to the Enterprise Security specific roles.

The table displays all ES specific capabilities. To customize a role and add access to Enterprise Security features, add the capabilities listed and modify the app metadata files to add the role name.

ES Feature	Capabilities required	Additional metadata changes
Credential Manager	admin_all_objects	No
Correlation searches	edit_correlationsearches schedule_search	In apps: DA-, SA-, Splunk_(DA|SA|TA)_* and ES: <app>/metadata/local.meta [savedsearches] access = read : [ * ], write : [ admin,role1,role2 ]
Export content	edit_correlationsearches	No
Log review settings	edit_log_review_settings	No
Edit Lookups	edit_lookups	In apps: DA-, SA-, Splunk_(DA|SA|TA)_* and ES: <app>/metadata/local.meta [lookups] access = read : [ * ], write : [ admin,role1,role2 ]
Manage Lookups	edit_lookups	In apps: DA-, SA-, Splunk_(DA|SA|TA)_* and ES: <app>/metadata/local.meta [lookups] access = read : [ * ], write : [ admin,role1,role2 ] In app: SplunkEnterpriseSecuritySuite/metadata/local.meta [collections/es_managed_lookups] access = read : [ * ], write : [ admin,role1,role2 ]

Advanced Filter or per-panel filtering	edit_per_panel_filters	In apps: DA-, SA-, Splunk_(DA|SA|TA)_* and ES: <app>/metadata/local.meta [lookups] access = read : [ * ], write : [ admin,role1,role2 ]

Suppressions	edit_suppressions	No
Threat Lists	edit_modinput_threatlist	No

Adjust the concurrent searches for a role

Splunk Enterprise defines a limit on searches to be run concurrently for user and power roles by default. After Enterprise Security is installed, increase the limits for roles other than admin.

To further increase the number of concurrent searches for a role:

1. Click Apps > Manage Apps.
2. Click Setup next to Enterprise Security.
3. Change the number of concurrent searches for the role and save.

To change the default search quota manually, edit the authorize.conf file:

• Edit the file at $SPLUNK_HOME/etc/system/local/authorize.conf and set srchJobsQuota for each role.

Example:

   [role_user]
   srchJobsQuota = 15

Configure the roles to search multiple indexes

Data sources being ingested by Splunk Enterprise are stored in multiple indexes. Multiple indexes are used to control access to data and to accommodate varying retention policies in data sources.

By default, all roles are configured to search only in the main index as the default. To enable the searching of multiple indexes, you must manually assign the indexes that contain relevant security data to all ES roles. If the roles are not updated, searches and other knowledge objects that rely on search results will not reflect the data from unassigned indexes.

Note: When adding indexes to a role, default search indexes must not include summary indexes, as this can cause a search and summary index loop.

See "Set up multiple indexes" and "Add users and assign roles" in the Splunk documentation for more information.
