Users & Access

tCell uses the Insight cloud’s role-based access control framework to manage global user accounts and permissions. Additional per-app controls are included in tCell and require varying levels of user permissions to access.

Types of User Access

tCell provides user access at two levels:

  • Global Roles - Global access roles provide user accounts with a minimum level of access to all tCell applications within the tCell customer domain.
  • Application Roles - Per-app access roles provide user accounts with increased privileges beyond the global access level for specific tCell apps.

Global Roles

All users have a global role. The global role sets a minimum access level for that user to all tCell apps. Global roles include:

  • Read-Only
  • Read-Write
  • Admin

The global "Read-Only" role permits access to information across all apps. Users in this role can see all app data such as events, package version information, and agents installed. Users in this role cannot modify the configuration of any apps such as changing policies or setting up alerts.

Members assigned to the "Read-Write" role can see all data like the Read-Only role, but can also make changes to all app configurations. This role can modify collected data and requests or client IP addresses to block.. However, users with a Read-Write role cannot create or delete tCell Apps, or modify other users.

The "Admin" role grants all capabilities available to the Read-Write role, but adds the ability to modify, add and remove other user logins. Global Admin role members can also create and delete tCell apps.

Global Role Actions

The following actions can only be taken by the roles listed:

ActionRoles
Access information across all appsRead-only, Read-write, Global admin
Modify app configurationsRead-write, Global admin
Modify, add, remove user loginsGlobal admin
Create and delete tCell appsGlobal admin
Create and own appsGlobal Admin, Read-Write

Admins cannot modify their own role

As a special limitation, admins cannot modify their own role, to prevent the possibility of the last admin removing their admin privileges. If you need to remove global Admin access from a user, do so under a different Admin user. If necessary you may need to create a new Admin user or promote an existing user to Admin.

Read more about global roles in the Insight User Management documentation.

Application roles

Users can also have roles scoped to a specific tCell application. These roles do not restrict access to the app, only increase it. A user's access to an app is the greater of their global role and the app-specific role.

The three levels of access are:

  • Read-Only
  • User
  • Admin

The "Read-Only" role provides access to review all collected data, while the "User" role permits review the data as well as configure the app.

As an app-specific role, "Admin" role access allows users to edit app-specific roles for other users. Admins can select users who need additional access to the app beyond their global access.

Note

Users with an app-specific Admin role cannot create or remove user accounts from the tCell system. Only global admins can bring users into the customer account.

Permissions for Apps

The following actions can only be taken by the corresponding roles:

ActionRoles
Create and own appsRead-Write, Admin
Review data for the appRead-only, User, Admin
Configure the appUser, Admin
Change user rolesAdmin
Add users to the appAdmin

User Management Examples

Global User

Richard has a global role of Read-Write, and is an Admin in the “Cheese Shop” app. Richard can:

  • Create apps. He will be the app admin for his apps.
  • View all data within the entire customer-specific tCell environment
  • Change the configuration of all apps
  • Give access at various levels to the “Cheese Shop” app to accounts that already exist in the system. For example, Richard can enable a user with global Read-Write access to be an Admin within the context of the Cheese Shop app

Global Admin

Duval has the Admin global role. No per-app roles will have any effect. Duval will have administrative access to all apps, even if his account has an app-specific role declared.
If Duval’s access is later reduced below app-specific roles, the app-specific settings would permit Duval to keep those levels of access in those apps, even if Duval’s new global role offered fewer privileges.

Managing User Roles

There are a few places where users and admins can make changes to user access. Global admins can make changes to tCell accounts from Insight User Management. This access includes:

  • Adding users to tCell
  • Deleting users from tCell
  • Granting Insight cloud admin role
  • Changing tCell product role

Additionally, access for users with app-specific admin access to tCell includes:

  • Adding, editing, and deleting app-specific roles
  • Enabling or disabling tCell global role
