Configure Cisco Firepower Management Center to interoperate with Okta via RADIUS

Okta provides the ability for organizations to manage authorization and access to on-premises applications and resources using the RADIUS protocol and the Okta RADIUS agent. With the Okta RADIUS Server Agent organizations can delegate authentication to Okta.
This page describes how to configure Cisco Firepower Management Center and Cisco Firepower Threat Defense Next General Firewall to use Okta RADIUS Server Agent for MFA.

Typical architecture

Typically a client uses the Cisco anyconnect Secure Mobility client connecting to a Cisco Firepower firewall. Users are authenticated using the Okta RADIUS agent backed by Microsoft Active directory. During authentication MFA is used, often using a mobile device. See Supported factors for a complete list of supported factors.

Before you begin

Before installing the Okta RADIUS Agent ensure that you have met these minimum requirements for network connectivity:

Source	Destination	Port/Protocol	Description
Okta RADIUS Agent	Okta Identity Cloud	TCP/443 HTTP	Configuration and authentication traffic
Client Gateway	Okta RADIUS Agent	UDP/1812 RADIUS (Default, may be changed in RADIUS app install and configuration)	RADIUS traffic between the gateway (client) and the RADIUS Agent (server)

Supported factors

The following MFA Factors are supported:

When integrating with Okta RADIUS, the maximum supported number of enrolled factors is dependent on the size of resulting challenge message. Okta recommends that no more than eight ( 8 ) be enrolled at one time.

MFA Factor	Password Authentication Protocol PAP
Custom TOTP Authentication	Supported
Duo(Push, SMS and Passcode only)	Supported
Email	Supported
Google Authenticator	Supported
Okta Verify (TOTP and PUSH)	Supported
RSA Token	Supported
Security Question	Supported
SMS authentication	Supported
Symantec VIP	Supported
Voice Call	Supported
YubiKey	Supported

Note

The U2F Security and Windows Hello MFA factors are not compatible with RADIUS-enabled implementations.
For additional information about the RADIUS apps refer to Configuring RADIUS applications in Okta.

Typical workflow

Task	Description
Download and install. the RADIUS agent	Download the Okta RADIUS Agent from the Settings > Downloads page your in Okta org. Note that there are both Windows and Linux agents. Install either the Windows or Linux RADIUS agents as appropriate for your environment. For throughput, availability and other considerations, see Okta RADIUS Server Agent Deployment Best Practices.
Optional Download and Install the Okta AD agent	Optional Download the Okta AD Agent installer from the Settings > Downloads page your in Okta org. Install and configure the Okta Active Directory agent. For a complete list of tasks see Get started with Active Directory integration. The active directory user needed for this process only needs domain user capabilities however it is recommended to install the agent with administrator privileges on a server which has Windows AD RSAT tools installed.
Configure application	In your Okta org, configure the Cisco ASA - RADIUS application. This integration works with all RADIUS applications. Its not mandatory to use the Cisco ASA application.
Configure the Cisco Firewall Management Center	Using the Cisco Firewall Management Center tool, configure Configure Cisco Firewall Management Center for RADIUS.
Test	Test the newly integrated agent.
