The integration of FortiNAC-F with FortiGate VPN requires a specific policy workflow to bridge the gap between initial user authentication and full network access. When a user connects to the VPN, the FortiGate typically provides the User ID and IP address, but FortiNAC-F requires a MAC address to uniquely identify and manage the endpoint's record.

According to the FortiGate VPN Integration Guide, the Endpoint Compliance Policy is a mandatory component of this setup because it is used to designate the required agent type. Because a VPN connection is Layer 3, FortiNAC cannot 'see' the MAC address through traditional SNMP or L2 polling. The compliance policy instructs the system to present a Captive Portal to the remote user, requiring them to download and run either the Persistent or Dissolvable Agent. The agent then reports the device's MAC address back to FortiNAC, allowing the system to correlate the VPN session with a host record.

Once the agent is running and the MAC is known, FortiNAC-F can evaluate the device's security posture (if scanning is configured) and send the necessary FSSO tags back to the FortiGate to lift the initial network restrictions. Without the compliance policy to enforce the agent requirement, the connection would remain in an isolated 'IP-only' state with no unique hardware identity.

'The Endpoint Compliance Policy is necessary to control the agent requirement for VPN users. Create a default VPN Endpoint Compliance Policy to distribute an agent via captive portal for isolated machines. This policy allows the administrator to designate the required agent type (Persistent or Dissolvable) that will be used to collect the hardware (MAC) address and perform health scans on the remote endpoint.' --- FortiNAC FortiGate VPN Integration Guide: Default Endpoint Compliance Policy (Optional) Section.

In FortiNAC-F, the Device Profiler is a rule-based engine that evaluates unknown 'rogue' devices and classifies them based on fingerprints and behavior. When a profiling rule matches a device, the administrator can configure the rule to automatically register that device. The registration process can place the device record in two primary locations: the Topology View (as a device) or the Host View (as a registered host).

According to the FortiNAC-F Administration Guide, registering a device in the Host View provides significant advantages for identity management and historical tracking. First, the devices can be associated with a user (C). In the FortiNAC database architecture, the Host View is the primary repository for endpoint identity; placing a profiled device here allows the system to link that hardware (MAC address) to a specific user account, whether that user is an employee, guest, or a system-level 'owner'. This association is essential for Role-Based Access Control (RBAC) and for tracking accountability across the network fabric.

Second, devices registered in the Host View will have connection logs (B). FortiNAC-F maintains a detailed operational history for all host records, including every instance of the device connecting to or disconnecting from a port, its IP address assignments, and the specific policies applied during each session. These logs are invaluable for troubleshooting connectivity issues and for security forensic audits, as they provide a clear timeline of the device's lifecycle on the network. In contrast, devices managed only in the Topology View are typically treated as infrastructure components where the focus is on device availability rather than individual session history.

'Devices that are registered and associated with a user are placed in the Host View and removed from the Profiled Devices window... Placing a device in the Host View allows for the tracking of connection history and the association of the device with a specific identity or user record within the FortiNAC database.' --- FortiNAC-F Administration Guide: Device Profiler How it Works.

The User/Host Profile is the primary mechanism in FortiNAC-F for identifying and categorizing endpoints to determine their level of network access. According to the FortiNAC-F Administration Guide, a profile is built using a combination of criteria that define 'Who' is connecting, 'What' device they are using, and 'Where' they are located on the network.

The three main categories of criteria available in the configuration are:

Host or User Attributes (B): This includes specific details such as the host's operating system, the user's role (e.g., Employee, Contractor), or custom attributes assigned to the record.

Host or User Group Memberships (A): Profiles can be configured to match endpoints that are members of specific internal FortiNAC groups or synchronized directory groups (like LDAP or Active Directory groups). This allows for broad policy application based on organizational structure.

Location (E): The 'Where' component allows administrators to restrict a profile match to specific physical or logical areas of the network, such as a particular switch, a group of ports, or a specific SSID.

Criteria like an 'applied access policy' (D) are the outcome of a profile match rather than a criterion used to define the profile itself. Similarly, the 'Adapter current VLAN' (C) is a dynamic state that changes based on enforcement and is not a standard static identifier used for profile matching.

'User/Host Profiles are used to identify the hosts and users to which a policy will apply. Profiles are created by selecting various criteria in the Who/What (Attributes and Groups) and Where (Locations) sections. Attributes can include Host Role, User Role, and OS. Group memberships allow matching based on internal or directory-based groups. Location criteria allow for filtering based on the device or port where the host is connected.' --- FortiNAC-F Administration Guide: User/Host Profile Configuration.

In FortiNAC-F, MAC notification traps (also known as MAC Move or MAC Change traps) are essential for achieving real-time visibility of endpoint connections and disconnections. When a device connects to a switch port, the switch generates an SNMP trap that informs FortiNAC-F of the new MAC address on that specific interface. This allows FortiNAC-F to immediately initiate the profiling and policy evaluation process without waiting for the next scheduled L2 poll.

According to the FortiNAC-F Administration Guide and Switch Integration documentation, MAC notification traps should be configured on all ports except uplink ports. Uplink ports are the interfaces that connect one switch to another or to the core network. Because these ports see the MAC addresses of every device on the downstream switches, enabling MAC notification on uplinks would cause the switch to send a massive volume of redundant traps to FortiNAC-F every time any device anywhere in the downstream branch moves or reconnects. This can overwhelm the FortiNAC-F process queue and degrade system performance.

By only enabling these traps on 'edge' or 'access' ports---where individual endpoints like PCs, printers, and VoIP phones connect---FortiNAC-F receives precise data regarding exactly where a device is physically located. Uplinks should be identified in the FortiNAC-F inventory as 'Uplink' or 'Learned Uplink,' which tells the system to ignore MAC data seen on those specific ports.

'To ensure accurate host tracking and optimal system performance, SNMP MAC notification traps must be enabled on all access (downlink) ports. Do not enable MAC notification traps on uplink ports, as this will result in excessive and unnecessary trap processing. Uplink ports should be excluded to prevent the system from attempting to map multiple downstream MAC addresses to a single infrastructure interface.' --- FortiNAC-F Administration Guide: SNMP Configuration for Network Devices.

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.
