Which three statements best describe a flow-based antivirus profile?

The correct answer highlights that flow-based inspection employs a hybrid of the scanning modes used in proxy-based inspection. In a flow-based antivirus profile, FortiGate processes traffic in a way that balances the need for security with efficiency. Unlike proxy-based inspection, which requires complete file buffering before any scanning occurs, flow-based inspection can utilize techniques from proxy inspection to analyze parts of the data stream while still allowing certain flow characteristics. This enables quicker responses to network threats while maintaining operational velocity.

In addition, understanding the performance optimization aspect supports how flow-based inspection is designed to be less resource-intensive. It achieves a faster throughput since it does not involve the overhead of complete file buffering before inspection, making it suitable for real-time applications where latency is crucial.

Recognizing that FortiGate inspects traffic as it flows through the system, rather than after transmission or through the entire buffering process, exemplifies the real-time nature and practical advantages of flow-based antivirus profiles. This immediate analysis allows for quicker identification and response to threats.

Overall, these points illustrate how flow-based antivirus profiles are designed for efficiency and speed, which is especially important in high-throughput environments.
