Configure Local or External Authentication for Firewall Administrators

You can use Local Authentication and External Authentication Services to authenticate administrators who access the firewall. These authentication methods prompt administrators to respond to one or more authentication challenges, such as a login page for entering a username and password.
If you use an external service to manage both authentication and authorization (role and access domain assignments), see:
  1. (External authentication only) Enable the firewall to connect to an external server for authenticating administrators.
    Configure a server profile:
  2. (Local database authentication only) Configure a user database that is local to the firewall.
    1. Add the user account to the local database.
    2. (Optional) Add the user group to the local database.
  3. (Local authentication only) Define password complexity and expiration settings.
    These settings help protect the firewall against unauthorized access by making it harder for attackers to guess passwords.
    1. Define global password complexity and expiration settings for all local administrators. The settings don’t apply to local database accounts for which you specified a password hash instead of a password (see Local Authentication).
      1. Select DeviceSetupManagement and edit the Minimum Password Complexity settings.
      2. Select Enabled.
      3. Define the password settings and click OK.
    2. Define a Password Profile.
      You assign the profile to administrator accounts for which you want to override the global password expiration settings. The profiles are available only to accounts that are not associated with a local database (see Local Authentication).
      1. Select DevicePassword Profiles and Add a profile.
      2. Enter a Name to identify the profile.
      3. Define the password expiration settings and click OK.
  4. (Kerberos SSO only) Create a Kerberos keytab.
    A keytab is a file that contains Kerberos account information for the firewall. To support Kerberos SSO, your network must have a Kerberos infrastructure.
  5. Configure an authentication profile.
    If your administrative accounts are stored across multiple types of servers, you can create an authentication profile for each type and add all the profiles to an authentication sequence.
    Configure an Authentication Profile and Sequence. In the authentication profile, specify the Type of authentication service and related settings:
    • External service—Select the Type of external service and select the Server Profile you created for it.
    • Local database authentication—Set the Type to Local Database.
    • Local authentication without a database—Set the Type to None.
    • Kerberos SSO—Specify the Kerberos Realm and Import the Kerberos Keytab.
  6. Assign the authentication profile or sequence to an administrator account.
    1. Configure a Firewall Administrator Account.
      • Assign the Authentication Profile or sequence that you configured.
      • (Local database authentication only) Specify the Name of the user account you added to the local database.
    2. Commit your changes.
    3. (Optional) Test Authentication Server Connectivity to verify that the firewall can use the authentication profile to authenticate administrators.
