How does FortiGate classify incoming traffic?

FortiGate classifies incoming traffic primarily by analyzing packet headers and applying security policies based on predefined criteria. This process involves examining various attributes of the packets, such as their source and destination IP addresses, protocol type, port numbers, and other relevant parameters found in the packet headers.

This method allows FortiGate to determine the nature of the traffic, whether it is benign or malicious, and to enforce appropriate security measures accordingly. For example, it can identify whether the traffic is part of an established session, if it matches any defined rules, or if it requires specific inspection.

Understanding this classification process is essential for managing network security effectively, as it enables the deployment of tailored security policies that protect the network from threats while also allowing legitimate traffic to flow uninterrupted. In contrast, the other options do not accurately reflect the comprehensive approach FortiGate uses for traffic classification. Counting packets, tracking login times, or inspecting encryption types are not primary methods for traffic classification and do not encompass the complexity of network traffic management that FortiGate implements.
