What does a FortiGate device typically use for deploying security policies?

A FortiGate device uses security policies as the primary means for deploying security measures. These security policies define how traffic is inspected, filtered, and controlled as it passes through the FortiGate firewall. They allow administrators to specify source and destination addresses, services, and the actions to be taken on the traffic, such as allowing or blocking it.

Security policies are integral to the operation of FortiGate devices, enabling robust and flexible security configurations tailored to the specific needs of an organization. They function at various levels, including application and user identification, which enhances the protection mechanisms beyond traditional network layer controls.

Access Control Lists (ACLs) are often associated with controlling traffic in networking contexts, but they don't offer the breadth of capabilities found in security policies deployed by FortiGate devices. Network Access Policies could refer to broader access control methods, including those integrated into managed network environments but are not the specific method implemented by FortiGate for security enforcement. Routing Policies pertain to the direction that traffic should take through a network rather than how traffic is secured, which again underscores why security policies are central to FortiGate's operation.
