Users and Role Based Access Control

Introduction

In OpenCTI, the RBAC system not only related to what users can do or cannot do in the platform (aka. Capabilities) but also to the system of data segregation. Also, platform behavior such as default home dashboards, default triggers and digests as well as default hidden menus or entities can be defined across groups and organizations.

High level design

Roles

Roles are used in the platform to grant the given groups with some capabilities to define what users in those groups can do or cannot do.

Manage roles

You can manage the roles in Settings > Security > Roles.

To create a role, just click on the + button:

Then you will be able to define the capabilities of the role:

Users

You can manage the users in Settings > Security > Users. If you are using Single-Sign-On (SSO), the users in OpenCTI are automatically created upon login.

To create a user, just click on the + button:

Manage a user

When access to a user, it is possible to:

• Visualize information including the token
• Modify it, reset 2FA if necessary
• Manage its sessions
• Manage its triggers and digests
• Visualize the history and operations
• Manage its max confidence levels

From this view you can edit the user's information by clicking the "Update" button, which opens a panel with several tabs.

• Overview tab: edit all basic information such as the name or language
• Password tab: change the password for this user
• Groups tab: select the groups this user belongs to
• Organization Admin tab: see Organization administration
• Confidences tab: manage the user's maximum confidence level and overrides per entity type

Mandatory max confidence level

A user without Max confidence level won't have the ability to create, delete or update any data in our platform. Please be sure that your users are always either assigned to group that have a confidence level defined or that have an override of this group confidence level.

Groups

Groups are the main way to manage permissions and data segregation as well as platform customization for the given users part of this group. You can manage the groups in Settings > Security > Groups.

Here is the description of the group available parameters.

Parameter	Description
Auto new markings	If a new marking definition is created, this group will automatically be granted to it.
Default membership	If a new user is created (manually or upon SSO), it will be added to this group.
Roles	Roles and capabilities granted to the users belonging to this group.
Default dashboard	Customize the home dashboard for the users belonging to this group.
Default markings	In Settings > Customization > Entity types, if a default marking definition is enabled, default markings of the group is used.
Allowed markings	Grant access to the group to the defined marking definitions, more details in data segregation.
Max shareable markings	Grant authorization to the group to share marking definitions.
Triggers and digests	Define defaults triggers and digests for the users belonging to this group.
Max confidence level	Define the maximum confidence level for the group: it will impact the capacity to update entities, the confidence level of a newly created entity by a user of the group.

Max confidence level when a user has multiple groups

A user with multiple groups will have the the highest confidence level of all its groups. For instance, if a user is part of group A (max confidence level = 100) and group B (max confidence level = 50), then the user max confidence level will be 100.

Manage a group

When managing a group, you can define the members and all above configurations.

Organizations

Users can belong to organizations, which is an additional layer of data segregation and customization. To find out more about this part, please refer to the page on organization segregation.

Organization administration

Platform administrators can promote members of an organization as "Organization administrator". This elevated role grants them the necessary capabilities to create, edit and delete users from the corresponding Organization. Additionally, administrators have the flexibility to define a list of groups that can be granted to newly created members by the organization administrators. This feature simplifies the process of granting appropriate access and privileges to individuals joining the organization.

The platform administrator can promote/demote an organization admin through its user edition form.

Organization admin rights

The "Organization admin" has restricted access to Settings. They can only manage the members of the organizations for which they have been promoted as "admins".
