In FortiNAC-F, accountability and forensic tracking of configuration changes are managed through the Admin Auditing functionality. When an administrator performs an action that modifies the system state--such as creating a policy, changing a device's status, or adding a switch port to an Enforcement Group--the system generates an audit record. This record is essential for troubleshooting scenarios where unauthorized or accidental configuration changes have occurred, leading to unintended network behavior.
The Admin Auditing view (found under Logs > Admin Auditing) provides a comprehensive log of the "Who, What, and When" for every administrative session. Each entry includes the username of the administrator, the source IP address from which they accessed the FortiNAC-F console, a precise timestamp, and a detailed description of the modification. In the scenario described, where port have been incorrectly added to enforcement groups, the Admin Auditing view allows a supervisor to filter by the specific "Port" or "Group" object to identify exactly which administrator executed the command.

FortiNAC-F serves as a central manager for security events originating from a diverse ecosystem of third-party security appliances, such as FortiGate, Check Point, and Cisco. Each vendor utilizes its own internal scale for severity levels within syslog messages (e.g., Check Point uses a
1? scale, while others may use 0?). To provide a consistent response regardless of the source, FortiNAC-F uses Severity Mappings to normalize these incoming values.
According to the FortiNAC-F Administration Guide, severity mappings allow the administrator to translate vendor-specific threat levels into standardized FortiNAC Security Levels (such as High, Medium, or Low Violation). When a syslog message arrives, the parser extracts the vendor's severity code, and the system immediately references the Security Event Severity Level Mappings table to determine how that event should be categorized internally. This normalization is vital because it allows a single Security Alarm to be configured to respond to any "High Violation" event, whether it was reported as a "Critical" by one vendor or a "Level 5" by another.
Without these mappings, the administrator would have to create separate, redundant security rules for every vendor to account for their different naming conventions and numerical scales.
"Each vendor defines its own severity levels for syslog messages. The following table shows the equivalent FortiNAC security level... To normalize these events, configure the Severity Level Mappings found in the device integration guides. This allows FortiNAC to generate a consistent security event that can then trigger an alarm regardless of the reporting vendor's specific terminology."

MAC notification traps must be enabled on all ports of a supported switch so FortiNAC-F can receive MAC address learning and movement events regardless of where endpoints connect.
This comprehensive coverage ensures accurate device discovery, tracking, and enforcement across the entire switch.

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.
