Configure TACACS+ Authentication for a WildFire Cluster

Configure TACACS+ authentication for all WildFire appliances in a WildFire cluster.
You can use a TACACS+ server to authenticate administrative access to the CLI of the WildFire appliances in a WildFire cluster. You can also define Vendor-Specific Attributes (VSAs) on the TACACS+ server to manage administrator authorization. Using VSAs enables you to quickly change the roles, access domains, and user groups of administrators through your directory service, which is often easier than reconfiguring settings on Panorama.
  1. Configure TACACS+ authentication.
    1. Add a TACACS+ server profile.
      The profile defines how a WildFire appliance connects to the TACACS+ server.
      1. Select
        Panorama
        Server Profiles
        TACACS+
        and
        Add
        a profile.
      2. Enter a
        Profile Name
        to identify the server profile.
      3. Enter a
        Timeout
        interval in seconds after which an authentication request times out (default is 3; range is 1–20).
      4. Select the
        Authentication Protocol
        (default is
        CHAP
        ) that Panorama uses to authenticate to the TACACS+ server.
      5. Select
        CHAP
        if the TACACS+ server supports that protocol; it is more secure than
        PAP
        .
      6. Add
        each TACACS+ server and enter the following:
        1. Name
          to identify the server.
        2. TACACS+ Server
          IP address or FQDN.
        3. Secret/Confirm Secret
          (a key to encrypt usernames and passwords).
        4. Server
          Port
          for authentication requests (default is 49).
      7. Click
        OK
        to save the server profile.
    2. Assign the TACACS+ server profile to an authentication profile.
      The authentication profile defines authentication settings that are common to a set of administrators.
      1. Select
        Panorama
        Authentication Profile
        and
        Add
        a profile.
      2. Enter a
        Name
        to identify the profile.
      3. Set the
        Type
        to
        TACACS+
        .
      4. Select the
        Server Profile
        you configured.
      5. Select
        Retrieve user group from TACACS+
        to collect user group information from VSAs defined on the TACACS+ server.
        Panorama matches the group information against the groups you specify in the Allow List of the authentication profile.
      6. Select
        Advanced
        and, in the Allow List,
        Add
        the administrators that are allowed to authenticate with this authentication profile.
      7. Click
        OK
        to save the authentication profile.
  2. Configure the authentication for the WildFire cluster.
    1. Select
      Panorama
      Managed WildFire Clusters
      and select the WildFire cluster you previously added.
    2. Select the
      Authentication Profile
      you configured in the previous step.
      If a global authentication profile is not assigned you must assign an authentication profile to each individual local administrator to leverage remote authentication.
    3. Configure the authentication
      Timeout Configuration
      for a WildFire appliance.
      1. Enter the number of
        Failed Attempt
        s before a user is locked out of a WildFire appliance CLI.
      2. Enter the
        Lockout Time
        , in minutes, for which a WildFire appliance locks out a user account after that user reaches the configured number of
        Failed Attempt
        s.
      3. Enter the
        Idle Timeout
        , in minutes, before the user account is automatically logged out due to inactivity.
      4. Enter the
        Max Session Count
        to set how many user accounts can simultaneously access a WildFire appliance.
      5. Enter the
        Max Session Time
        the administrator can be logged in before being automatically logged out.
    4. Add the WildFire appliance administrators.
      Administrators may either be added as a local administrator or as an imported Panorama administrator—but not both. Adding the same administrator as both a local administrator and as an imported Panorama administrator is not supported and causes the Panorama commit to fail. For example, the commit to Panorama fails if you add
      admin1
      as both a local and Panorama administrator.
      1. Add
        and configure new administrators unique to the WildFire appliances in the WildFire cluster. These administrators are specific to the WildFire appliances in the WildFire cluster for which they are created and you manage these administrators from this table.
      2. Add
        any administrators configured on Panorama. These administrators are created on Panorama and imported to the WildFire appliances in the WildFire cluster.
    5. Click
      OK
      to save the WildFire cluster authentication configuration.

  3. Commit
    and then
    Commit and Push
    your configuration changes.
  4. Access the WildFire appliance CLI to verify you can successfully access a WildFire appliance using the local admin user.
