In FortiNAC-F, the Security Incidents engine is used to automate responses to security threats reported by external devices. When an administrator wants to enforce a policy, such as quarantining contractors who access restricted websites, they must create a Security Rule . A Security Rule acts as the "if-then" logic that correlates incoming security data with the internal host database.

The documentation specifies that a Security Rule consists of three primary configurable components:

User/Host Profile: This identifies who or what the rule applies to (in this case, "Contractors").

Trigger: This is the event that initiates the rule evaluation. In this scenario, the Trigger would be configured to match specific syslog messages or NetFlow data indicating access to prohibited websites. Triggers use filters to match vendor-specific data, such as a "Web Filter" event from a FortiGate.

Action: This defines what happens when the Trigger and User/Host Profile are matched. For this scenario, the administrator would select a "Quarantine" action, which instructs FortiNAC-F to move the endpoint to a restricted VLAN or apply a restrictive ACL.

While "Methods" (A) relate to authentication and "Security Strings" (E) are used for specific SNMP or CLI matching, they are not the structural components of a Security Rule in the Security Incidents menu.

"Security Rules are used to perform a specific action based on certain criteria... To configure a Security Rule, navigate to Logs > Security Incidents > Rules . Each rule requires a Trigger to define the event criteria, an Action to define the automated response (such as Quarantine), and a User/Host Profile to limit the rule to specific groups." — FortiNAC-F Administration Guide: Security Rules and Incident Management.

In FortiNAC-F, the RADIUS Attribute Groups feature allows administrators to return customized RADIUS attributes (such as specific VLAN IDs, filter IDs, or vendor-specific attributes) in an Access-Accept packet sent back to a network device. This is particularly useful for supporting "Generic RADIUS" devices that are not natively supported but can be managed using standard AVPairs.

According to the FortiNAC-F Generic RADIUS Wired Cookbook and the RADIUS Attribute Groups section of the Administration Guide, there is one critical prerequisite for this feature to function: the inbound RADIUS request must contain the Calling-Station-ID attribute . The Calling-Station-ID typically contains the MAC address of the connecting endpoint. Because FortiNAC-F is a host-centric system, it uses the MAC address as the unique identifier to look up the host record, evaluate the associated Network Access Policy, and determine which Logical Network (and thus which Attribute Group) should be applied. If the incoming request lacks this attribute, FortiNAC-F cannot reliably identify the host and, as a safety mechanism, will not include any user-defined RADIUS attributes in the response. This ensures that unauthorized or unidentifiable devices do not receive privileged access through misapplied attributes.

"Configure a set of attributes that must be included in the RADIUS Access-Accept packet returned by FortiNAC... Requirement: Inbound RADIUS request must contain Calling-Station-Id. Otherwise, FortiNAC will not include the RADIUS attributes. This attribute is used to identify the host and its current state within the FortiNAC database." — FortiNAC-F 7.6.0 Generic RADIUS Wired Cookbook: Configure RADIUS Attribute Groups.

The FortiNAC-F Manager (FortiNAC-M) is designed as a centralized management platform for large-scale distributed environments where multiple FortiNAC-F Control and Application (CA) appliances are deployed across different sites. According to the FortiNAC-F Manager Administration Guide , the deployment of a Manager simplifies administrative overhead in three specific ways:

First, it provides Global Version Control (B) . The Manager serves as a central repository for firmware and software updates, allowing administrators to push specific versions to all managed CAs simultaneously, ensuring consistency across the entire fabric. Second, it enables Pooled Licenses (D) . Instead of purchasing and managing individual licenses for every CA, licenses are centralized on the Manager. The Manager then distributes these licenses to the CAs as needed based on their host counts. This "floating" license model optimizes cost and prevents individual sites from running out of capacity while others have excess. Third, it offers Global Visibility (E) . The Manager aggregates host and device data from every managed CA into a single console. This "single pane of glass" allows an administrator to search for a specific MAC address or user across the entire global organization without logging into individual servers.

While the Manager can assist with configuration templates, authentication security policies (C) and infrastructure modeling (A) are still predominantly managed at the local CA level to ensure site-specific logic and performance.

"The FortiNAC Manager provides a central management console for multiple FortiNAC-F servers (CAs). Key benefits include: • License Management : Licenses are pooled on the Manager and allocated to managed CAs as needed. • Software Management : Firmware updates can be centrally managed and pushed to all CAs from the Manager. • Centralized Monitoring : Provides a global view of all hosts, adapters, and events across the entire managed environment." — FortiNAC-F Manager Administration Guide: Overview and Benefits.

When FortiNAC-F manages VPN clients through a FortiGate, the agent plays a fundamental role in device identification that standard network protocols cannot provide on their own. In a standard VPN connection, the FortiGate establishes a Layer 3 tunnel and assigns a virtual IP address to the client. While the FortiGate sends a syslog message to FortiNAC-F containing the username and this assigned IP address, it typically does not provide the hardware (MAC) address of the remote endpoint's physical or virtual adapter.

FortiNAC-F relies on the MAC address as the primary unique identifier for all host records in its database. Without the MAC address, FortiNAC-F cannot correlate the incoming VPN session with an existing host record to apply specific policies or track the device's history. By running either a Persistent or Dissolvable Agent, the endpoint retrieves its own MAC address and communicates it directly to the FortiNAC-F service interface. This allows the "IP to MAC" mapping to occur. Once FortiNAC-F has both the IP and the MAC, it can successfully identify the device, verify its status, and send the appropriate FSSO tags or group information back to the FortiGate to lift network restrictions.

Furthermore, while the agent can also perform compliance checks (Option D), the architectural requirement for the agent in a managed VPN environment is primarily driven by the need for session data correlation—specifically the collection of the IP and MAC address pairing.

"Session Data Components: • User ID (collected via RADIUS, syslog and API from the FortiGate). • Remote IP address for the remote user connection (collected via syslog and API from the FortiGate and from the FortiNAC agent). • Device IP and MAC address (collected via FortiNAC agent). ... The Agent is used to provide the MAC address of the connecting VPN user (IP to MAC)." — FortiNAC-F FortiGate VPN Integration Guide: How it Works Section.

In FortiNAC-F, the integration with FortiGate for Security Fabric and Single Sign-On (FSSO) allows the system to communicate the access level of an endpoint directly to the firewall using firewall tags . This eliminates the need for complex VLAN steering in some environments by allowing the FortiGate to apply policies based on these dynamic tags instead of just a physical or virtual network segment.

The actual assignment of the firewall tag value occurs within a Logical Network . In the FortiNAC-F architectural model, a Logical Network acts as a container for "Access Values". When an administrator configures a Logical Network (located under Network > Logical Networks ), they define what that network represents—such as "Corporate Access" or "Contractor Limited". Within that definition, they assign the specific Firewall Tag that matches the tag created on the FortiGate. Once a user or host matches a Network Access Policy , FortiNAC-F identifies the associated Logical Network and pushes the defined tag to the FortiGate via the FSSO connector.

It is important to note that while Network Access Policies (and by extension Security Rules ) are the logic engines that trigger the assignment, they do not hold the tag value itself. They simply point to a Logical Network, which serves as the central repository for that specific access configuration.

"To assign firewall tags, navigate to Network > Logical Networks . Select the desired logical network and click Edit . Under the Access Value section, select Firewall Tag as the type and enter the tag name exactly as it appears on the FortiGate. When a Network Access Policy matches a host, FortiNAC sends this tag to the FortiGate as an FSSO message." — FortiNAC-F Administration Guide: Logical Networks and Security Fabric Integration.

FortiNAC-F provides a robust engine for processing security notifications from third-party devices. For standard integrations, such as FortiGate or Check Point, the system comes pre-loaded with templates to interpret incoming data. However, when an administrator needs FortiNAC-F to process syslog messages from a vendor or device that is not supported by default, they must configure a Security Event Parser .

The Security Event Parser acts as the translation layer. It uses regular expressions (Regex) or specific field mappings to identify key data points within a raw syslog string, such as the source IP address, the threat type, and the severity. Without a parser, FortiNAC-F may receive the syslog message but will be unable to "understand" its contents, meaning it cannot generate the necessary Security Event required to trigger automated responses. Once a parser is created, the system can extract the host's IP address from the message, resolve it to a MAC address via L3 polling, and then apply the appropriate security rules. This allows for the integration of any security appliance capable of sending RFC-compliant syslog messages.

"FortiNAC parses the information based on pre-defined security event parsers stored in FortiNAC's database... If the incoming message format is not recognized, a new Security Event Parser must be created to define how the system should extract data fields from the raw syslog message. This enables FortiNAC to generate a security event and take action based on the alarm configuration." — FortiNAC-F Administration Guide: Security Event Parsers.
