Each firewall policy is assigned a Universally Unique Identifier (UUID). This UUID is essential when a FortiGate is part of a larger Security Fabric, managed by FortiManager, or sending logs to FortiAnalyzer. Unlike the Policy ID, which is only unique locally on a single FortiGate, the UUID is a globally unique attribute. This ensures that logs and policy information from different FortiGates can be accurately correlated and managed centrally without conflicts, which is critical for consistent reporting and administration across the fabric.

A. Log ID is a generic term and not the specific attribute used for uniquely identifying policies across devices.

C. The Policy ID is only unique on the local FortiGate and can cause conflicts when multiple devices are managed centrally.

D. Sequence ID is not a standard attribute used for this purpose in FortiGate firewall policies.

1. FortiOS 7.0.0 Administration Guide, "Firewall & DoS Protection" chapter, "Firewall policies" section. It states, "Each firewall policy has a universally unique identifier (UUID). When FortiGate is managed by FortiManager, the UUID is used to uniquely identify the policy."

2. FortiManager 7.0.0 Administration Guide, "Policy & Objects" chapter, "About policies" section. The documentation explains that UUIDs are used to track policy changes and ensure uniqueness across the management domain.
