Global Admin – GUI Language – Idle Timeout – FortiAnalyzer – FortiOS 6.2.3

GUI language

The GUI supports multiple languages, including:

l English l Simplified Chinese l Spanish l Traditional Chinese l Japanese l Korean

By default, the GUI language is set to Auto Detect, which automatically uses the language used by the management computer. If that language is not supported, the GUI defaults to English. For best results, you should select the language used by the operating system on the management computer.

For more information about language support, see the FortiAnalyzerRelease Notes.

To change the GUI language:

  1. Go to System Settings > Admin > Admin Settings.
  2. Under the View Settings, In the Language field, select a language, or Auto Detect, from the dropdown list.
  3. Click Apply to apply the language change.

  1. Enter the following CLI commands:

config system global set admin-lockout-duration <seconds>

end

To configure the number of retry attempts:

  1. Enter the following CLI commands:

config system global set admin-lockout-threshold <failed_attempts>

end

Example

To set the lockout threshold to one attempt and set a five minute duration before the administrator can try to log in again, enter the following CLI commands:

config system global set admin-lockout-duration 300 set admin-lockout-threshold 1

end

SAML admin authentication – FortiAnalyzer – FortiOS 6.2.3

SAML admin authentication

SAML can be enabled across all Security Fabric devices, enabling smooth movement between devices for the administrator. FortiAnalyzer can play the role of the identity provider (IdP) or the service provider (SP) when an external identity provider is available.

Devices configured to the IdP can be accessed through the Quick Access menu which appears in the top-right corner of the main menu. The current device is indicated with an asterisk (this feature is currently only supported in FAZ/FMG).

Logging into an SP device will redirect you to the IdP login page. By default, it is a Fortinet login page. After successful authentication, you can access other SP devices from within the same browser without additional authentication.

  1. Go to System Settings > SAML SSO.
  2. Select Identity Provider(IdP).
  3. In the IdP Certificate dropdown, choose a certificate where IdP is used.
  4. Select Download to get the IdP certificate, used later to configure SPs.
  5. Select Apply.
  6. In the SP Settings table, select Create to add a service provider.
  7. In the Edit Service Provider window: l Enter a name for the SP.
    • Select Fortinet as the SP Type.
    • If the SP is not a Fortinet product, select Custom as the SP Type and copy the SP Entity ID, SP ACS (Login) URL, and SP SLS (Logout) URL from your SPs configuration page.
    • Enter the SP IP address.
    • Copy down the IdP Prefix. It is required when configuring SPs.
  8. Select OK.
  9. A custom login page can be created by moving the Login Page Template toggle to the On position and selecting Customize.

To configure FortiAnalyzer as a service provider:

  1. Go to System Settings > SAML SSO.
  2. Select Service Provider(SP).
  3. Select Fortinet as the IdP Type.
  4. Enter the IdP IP address and the IdP prefix that you obtained while configuring the IdP device.
  5. Select the IdP certificate.

If this is a first-time set up, you can import the IdP certificate that you downloaded while configuring the IdP device.

  1. Confirm that the information is correct and select Apply.
  2. Repeat the steps for each FAZ/FMG that is to be set as a service provider.

Remote authentication server groups – FortiAnalyzer – FortiOS 6.2.3

Remote authentication server groups

Remote authentication server groups can be used to extend wildcard administrator access. Normally, a wildcard administrator can only be created for a single server. If multiple servers of different types are grouped, a wildcard administrator can be applied to all of the servers in the group.

Multiple servers of the same type can be grouped to act as backups – if one server fails, the administrator can still be authenticated by another server in the group.

To use a server group to authenticate administrators, you must configure the group before configuring the administrator accounts that will use it.

Remote authentication server groups can only be managed using the CLI. For more information, see the FortiAnalyzer CLI Reference.

To create a new remote authentication server group:

  1. Open the admin group command shell:

config system admin group

  1. Create a new group, or edit an already create group: edit <group name>
  2. Add remote authentication servers to the group:

set member <server name> <server name> …

  1. Apply your changes: end

To edit the servers in a group:

  1. Enter the following CLI commands:

config system admin group edit <group name> set member <server name> <server name> …

end

Only the servers listed in the command will be in the group.

To remove all the servers from the group:

  1. Enter the following CLI commands:

config system admin group edit <group name> unset member

end

All of the servers in the group will be removed.

To delete a group:

  1. Enter the following CLI commands:

config system admin group delete <group name>

end

TACACS+ servers – FortiAnalyzer – FortiOS 6.2.3

TACACS+ servers

Terminal Access Controller Access-Control System (TACACS+) is a remote authentication protocol that provides access control for routers, network access servers, and other network computing devices via one or more centralized servers. It allows a client to accept a user name and password and send a query to a TACACS authentication server. The server host determines whether to accept or deny the request and sends a response back that allows or denies network access to the user. The default TCP port for a TACACS+ server is 49.

If you have configured TACACS+ support and an administrator is required to authenticate using a TACACS+ server, the FortiAnalyzer unit contacts the TACACS+ server for authentication. If the TACACS+ server can authenticate the administrator, they are successfully authenticated with the FortiAnalyzer unit. If the TACACS+ server cannot authenticate the administrator, the connection is refused by the FortiAnalyzer unit.

To use a TACACS+ server to authenticate administrators, you must configure the server before configuring the administrator accounts that will use it.

To add a TACACS+ server:

  1. Go to System Settings > Admin > Remote Authentication Server.
  2. Select Create New > TACACS+ Server from the toolbar. The New TACACS+ Server pane opens.
  3. Configure the following settings, and then click OK to add the TACACS+ server.
Name Enter a name to identify the TACACS+ server.
Server Name/IP Enter the IP address or fully qualified domain name of the TACACS+ server.
Port Enter the port for TACACS+ traffic. The default port is 49.
Server Key Enter the key to access the TACACS+ server. The server key can be a maximum of 16 characters in length.
Authentication Type Select the authentication type the TACACS+ server requires. If you select the default ANY, FortiAnalyzer tries all authentication types.

RADIUS servers – FortiAnalyzer – FortiOS 6.2.3

RADIUS servers

Remote Authentication Dial-in User (RADIUS) is a user authentication and network-usage accounting system. When users connect to a server they type a user name and password. This information is passed to a RADIUS server, which authenticates the user and authorizes access to the network.

You can create or edit RADIUS server entries in the server list to support authentication of administrators. When an administrator account’s type is set to RADIUS, the FortiAnalyzer unit uses the RADIUS server to verify the administrator password at log on. The password is not stored on the FortiAnalyzer unit.

To use a RADIUS server to authenticate administrators, you must configure the server before configuring the administrator accounts that will use it.

To add a RADIUS server:

  1. Go to System Settings > Admin > Remote Authentication Server.
  2. Select Create New > RADIUS Server from the toolbar. The New RADIUS Server pane opens.
  3. Configure the following settings, and then click OK to add the RADIUS server.
Name Enter a name to identify the RADIUS server.
Server Name/IP Enter the IP address or fully qualified domain name of the RADIUS server.
Port Enter the port for RADIUS traffic. The default port is 1812. Some RADIUS servers use port 1645.
