In FortiOS 7.6, when FortiGate is integrated with FortiAnalyzer and FortiManager, firewall policies rely on a Universally Unique Identifier (UUID) to ensure proper policy tracking, synchronization, and log correlation across devices.
Why the UUID is required
Every firewall policy in FortiOS has a UUID.
FortiManager uses the UUID to:
Track policies across managed FortiGate devices
Maintain policy consistency during installs and revisions
FortiAnalyzer uses the UUID to:
Correlate logs accurately to the correct firewall policy
Preserve log association even if policy order or policy ID changes
Without a UUID:
Policy-to-log mapping can break
FortiManager cannot reliably manage or synchronize policies
FortiAnalyzer log analysis becomes inconsistent
This is explicitly documented in Fortinet administration and logging architecture references.
Why the other options are incorrect
B). Policy IDPolicy ID can change when policies are moved and is not reliable for long-term correlation across FortiManager and FortiAnalyzer.
C). Sequence IDSequence ID reflects GUI ordering only and has no role in log correlation.
D). Log IDLog ID is generated per log event, not per firewall policy.
