About User Profiles

A user profile defines a user's login, password, and role (permissions).

You can configure both internal and external profiles for users. Internal user profiles reside in Cisco DNA Center and external user profiles reside on an external AAA server.

A default user profile with SUPER-ADMIN-ROLE permissions is created when you install Cisco DNA Center.

About User Roles

Users are assigned user roles that specify the functions that they are permitted to perform:

  • Administrator (SUPER-ADMIN-ROLE): Users with this role have full access to all of the Cisco DNA Center functions. They can create other user profiles with various roles, including those with the SUPER-ADMIN-ROLE.

  • Network Administrator (NETWORK-ADMIN-ROLE): Users with this role have full access to all of the network-related Cisco DNA Center functions. However, they do not have access to system-related functions, such as backup and restore.

  • Observer (OBSERVER-ROLE): Users with this role have view-only access to the Cisco DNA Center functions. Users with an observer role cannot access any functions that configure or control Cisco DNA Center or the devices it manages.

Two-Factor Authentication

Two-factor authentication, also known as 2FA, adds another layer of security to user verification by using an identifier method in addition to a user's name and password. The identifier method is generally something that only the actual intended user possesses (such as a phone app or keyfob) and is intentionally separated from the original login method.

The Cisco DNA Center implementation of two-factor authentication supports the use of a token client (that generates single-use token codes after the appropriate PIN is entered), a token server (that validates token codes), and an authentication server to manage user access. Authentication can be handled using either the RADIUS or TACACS+ protocol.

The topics in this section describe:

  • The requirements that need to be in place in order to implement two-factor authentication.

  • The necessary configuration settings you need to make.

  • The Cisco DNA Center login procedure using two-factor authentication.

Prerequisites for Two-Factor Authentication

The following prerequisites must be in place in order to set up two-factor authentication for use with Cisco DNA Center:

  • An authentication server that is able to return attribute-value pairs to convey RBAC role authorizations for authenticated Cisco DNA Center users. In our example, we use Cisco Identity Services Engine (Cisco ISE) 2.3 Patch 1.

  • A two-factor token server that you will integrate with your authentication server. In our example, we use RSA Authentication Manager 7.2.

  • A token card application on the client’s machine that generates software tokens. In our example, we use RSA SecurID Software Token.

Two-Factor Authentication Workflow

Here is a summary of what happens when a user logs in to a Cisco DNA Center appliance on which two-factor authentication has been configured:

  1. In an RSA SecurID token client, a user enters their PIN to get a token code.

  2. In the Cisco DNA Center login page, they enter their username and token code.

  3. Cisco DNA Center sends the login request to Cisco ISE using either the RADIUS or TACACS+ protocol.

  4. Cisco ISE sends the request to the RSA Authentication Manager server.

  5. RSA Authentication Manager validates the token code and informs Cisco ISE that the user has been authenticated successfully.

  6. Cisco ISE matches the authenticated user with their configured authorization profile and returns the role=NETWORK-ADMIN-ROLE attribute-value pair.

  7. Cisco DNA Center grants access to the features and pages associated with the user's role-based access control (RBAC) role.

Configure Two-Factor Authentication

To configure two-factor authentication on your Cisco DNA Center appliance, complete the following procedure.

Procedure

Step 1

Integrate RSA Authentication Manager with Cisco ISE:

  1. In RSA Authentication Manager, create two users: cdnac_admin (for the Admin user role) and cdnac_observer (for the Observer role).

    For more information, see the "Add a User to the Internal Database" topic in the RSA Self-Service Console Help. To access this topic, do the following:

    1. Open the RSA Self-Service Console Help.

    2. In the Search help field, enter Add a User to the Internal Database and then click Search help.

  2. Create a new authentication agent.

    For more information, see the "Add an Authentication Agent" topic in the RSA Self-Service Console Help.

  3. Generate the Authentication Manager agent configuration file (sdconf.rec):

    1. From the RSA Security Console, choose Access > Authentication Agents > Generate Configuration File.

      The Configure Agent Timeout and Retries tab opens.

    2. For the Maximum Retries and Maximum Time Between Each Retry fields, use the default values.

    3. Click Generate Configuration File.

      The Download Configuration File tab opens.

    4. Click the Download Now link.

    5. When prompted, click Save to Disk to save a local copy of the zip file.

    6. Unzip the file and use this version of the sdconf.rec file to overwrite the version that is currently installed on the agent.

  4. Generate a PIN for the cdnac_admin and cdnac_observer users you created in Step 1a.

    For more information, see the "Create My On-Demand Authentication PIN" topic in the RSA Self-Service Console Help.

  5. Start Cisco ISE, choose Administration > Identity Management > External Identity Sources > RSA SecurID, and then click Add.

  6. In the RSA SecurID Identity Sources page, click Browse, choose the sdconf.rec file you downloaded, and then click Open.

  7. Check the Reauthenticate on Change PIN check box, then click Submit.

Step 2

Create two authorization profiles, one for the Admin user role and one for the Observer user role.

  1. In Cisco ISE, choose Policy > Policy Elements > Results > Authorization > Authorization Profiles.

  2. For both profiles, enter the following information:

    • Name field: Enter the profile's name.

    • Access Type field: Choose ACCESS_ACCEPT.

    • Advanced Attributes Settings area: Choose Cisco:cisco-av-pair from the first drop-down list.

      If you are creating an authorization profile for the Admin user role, choose Role=NETWORK-ADMIN-ROLE from the second drop-down list.

      If you are creating an authorization profile for the Observer user role, choose Role=OBSERVER-ROLE from the second drop-down list.

Step 3

Create an authentication policy for your Cisco DNA Center appliance.

In the Cisco Identity Services Engine Administrator Guide, Release 2.3, see the "Configure Authentication Policies" topic.

Step 4

Create two authorization policies, one for the Admin user role and one for the Observer user role.

In the Cisco Identity Services Engine Administrator Guide, Release 2.3, see the "Configure Authorization Policies" topic.

Step 5

In the RSA Authentication Manager Security Console, verify that software tokens have been assigned to both users.

For more information, see the "View a Token" topic in the RSA Self-Service Console Help.

Note 

If you need to assign tokens, complete the steps described in the "Assign a Software Token to a User" topic.
