Management VDOM

A dedicated administrative VDOM that separates management traffic from user traffic, allowing administrators to reach the firewall even when other VDOMs are under heavy load or misconfigured.

Related: Virtual Domain (VDOM), Administrative Access Protocol
Virtual Domain (VDOM)

An independent virtual firewall instance inside a physical FortiGate that has its own interfaces, routing table, firewall policies, and administrators, effectively partitioning one appliance into several logical devices.

Related: Management VDOM, Inter-VDOM Link, VDOM Mode
Inter-VDOM Link

A virtual point-to-point interface pair that connects two VDOMs so traffic can be routed or filtered between them without consuming physical ports.

Related: Virtual Domain (VDOM), Policy Route
VDOM Mode

The global setting that enables or disables multi-VDOM support on the device; changing it requires a reboot and resets VDOM-related configuration to defaults.

Related: Virtual Domain (VDOM), Configuration Backup
Global Configuration Scope

The configuration layer shared by all VDOMs, holding device-wide settings such as admin accounts, HA parameters, and global firewall objects that can be referenced from any VDOM.

Related: Virtual Domain (VDOM), Global Object
Global Object

A firewall address, service, or profile defined at the global level so it can be used by policies in multiple VDOMs while being maintained in a single place.

Related: Global Configuration Scope, Firewall Policy
HA Cluster

Two or more FortiGates configured to act as a single logical unit that shares session state and configuration, providing device redundancy if a member fails.

Related: Primary Node, Secondary Node, HA Heartbeat
Primary Node

The cluster member that actively processes traffic, owns the cluster IP addresses, and synchronizes configuration and session information to the secondary devices.

Related: Secondary Node, HA Synchronization, HA Failover
Secondary Node

A standby cluster member that keeps a synchronized copy of configuration and session state and takes over traffic processing if the primary becomes unavailable.

Related: Primary Node, HA Failover
HA Heartbeat

Periodic keepalive messages exchanged over heartbeat interfaces so cluster members can detect whether their peers are still reachable and healthy.

Related: HA Failover, Split-Brain
HA Failover

The process by which a secondary device assumes the primary role after the active member stops responding or loses monitored interfaces, minimizing traffic interruption.

Related: Primary Node, Monitored Interface, HA Heartbeat
Monitored Interface

An interface linked to an HA virtual cluster whose failure lowers the device's priority, causing a role change so traffic follows the surviving network path.

Related: HA Failover, HA Priority
HA Priority

A numeric value that determines which cluster member becomes primary; the highest value wins, and monitored interface failures can reduce it dynamically.

Related: Monitored Interface, Primary Node
HA Synchronization

The continuous replication of configuration changes and connection state from the primary to secondary members so failover preserves existing sessions.

Related: Primary Node, Session Pickup
Split-Brain

A failure condition where cluster members cannot communicate over heartbeat links and each believes it should be primary, potentially causing duplicate IP conflicts and inconsistent sessions.

Related: HA Heartbeat, HA Failover
FGCP

FortiGate Clustering Protocol, the native HA implementation that elects a primary by priority and monitored interface status and synchronizes configuration and sessions across members.

Related: HA Cluster, HA Priority, HA Synchronization
Static Route

A manually configured path that tells the firewall where to send traffic for a destination prefix, including the next-hop gateway or outgoing interface and an optional distance.

Related: Administrative Distance, Policy Route
Administrative Distance

A preference value used to rank routes to the same destination; lower values are preferred, and it is used to break ties between routes from different sources.

Related: Static Route, Route Selection
Policy Route

A rule that overrides the routing table for matching traffic based on criteria such as source address, protocol, or port, forwarding it to a specified gateway or interface.

Related: Static Route, Route Selection, Inter-VDOM Link
ECMP

Equal-cost multipath routing, where multiple routes with the same distance and priority to a destination are installed and traffic is load-balanced across their next hops.

Related: Static Route, Route Selection
Route Selection

The process of choosing the best path for a packet by comparing longest prefix match, administrative distance, priority, and metric among candidate routes.

Related: Administrative Distance, ECMP, Policy Route
Dynamic Routing Protocol

A protocol such as OSPF or BGP that automatically learns and advertises routes, adapting to topology changes without manual static route updates.

Related: OSPF Area, BGP Neighbor
OSPF Area

A logical grouping of OSPF routers that limits link-state flooding; all areas must connect to the backbone area zero, and inter-area routes are summarized at area borders.

Related: Dynamic Routing Protocol, Route Selection
BGP Neighbor

A configured peering session between BGP speakers that exchange route updates; it can be internal within one autonomous system or external between different autonomous systems.

Related: Dynamic Routing Protocol, Route Selection
Reverse Path Forwarding Check

A validation that a packet's source address is reachable through the interface it arrived on, dropping spoofed traffic when the check is strict.

Related: Route Selection, Firewall Policy
Firewall Policy

An ordered rule that matches traffic by source, destination, service, and schedule, then applies an action such as accept or deny along with security profiles and logging.

Related: Security Profile, Policy Route, UTM Profile
Security Profile

A set of inspection settings, such as antivirus, IPS, web filtering, or application control, attached to a policy to scan matching traffic for threats and policy violations.

Related: Firewall Policy, IPS Sensor, Application Control
UTM Profile

A consolidated profile that groups several security inspection features so they can be applied together to traffic accepted by a firewall policy.

Related: Security Profile, SSL Inspection
IPS Sensor

A configuration object containing signature filters and override actions that determines which intrusion prevention signatures are active and how matching traffic is handled.

Related: Security Profile, Application Control
Application Control

A security feature that identifies applications in network traffic regardless of port and enforces actions such as allow, block, or bandwidth limit per application.

Related: Security Profile, SSL Inspection
SSL Inspection

The process of decrypting TLS traffic so security profiles can examine it, then re-encrypting it, using certificate inspection or full deep inspection with a trusted CA.

Related: Security Profile, Application Control
Web Filter

A profile that rates and categorizes websites and applies actions such as block or allow, often combined with safe-search enforcement and content rating overrides.

Related: Security Profile, SSL Inspection
Authentication Rule

A policy that identifies which traffic must be authenticated, which authentication methods are permitted, and which user groups are allowed access.

Related: User Group, Firewall Policy, Captive Portal
User Group

A collection of local or remote user accounts referenced by policies and authentication rules so permissions can be managed for many users at once.

Related: Authentication Rule, LDAP Server, RADIUS Server
LDAP Server

A directory service connector the firewall queries to validate user credentials and retrieve group membership for identity-based policy enforcement.

Related: User Group, FSSO
RADIUS Server

An external authentication server that receives user credentials or accounting requests from the firewall and returns an accept or reject decision with attributes.

Related: User Group, Two-Factor Authentication
FSSO

Fortinet Single Sign-On, which learns user logon identity from domain controllers or collector agents so policies can match users without prompting them again.

Related: LDAP Server, User Group
Captive Portal

A web page presented to unauthenticated clients that collects credentials or terms acceptance before granting access through the firewall.

Related: Authentication Rule, User Group
Two-Factor Authentication

An authentication method requiring a second proof of identity, such as a one-time token or push approval, in addition to a password.

Related: RADIUS Server, Authentication Rule
Administrative Access Protocol

The set of protocols enabled on an interface, such as HTTPS, SSH, or SNMP, that determines how administrators and monitoring systems reach the device.
