How does FortiGate application control address evasion techniques used by peer-to-peer protocols?

FortiGate application control addresses evasion techniques used by peer-to-peer protocols through a multi-layered approach. Here are the steps:

1. Deep Packet Inspection (DPI): FortiGate uses DPI to analyze the content of network traffic at the application layer. This allows it to identify and classify peer-to-peer protocols based on their unique signatures and behavior.

2. Protocol Decoding: FortiGate decodes the protocols used by peer-to-peer applications to understand their structure and functionality. By doing so, it can accurately identify and control the traffic associated with these protocols.

3. Application Control Policies: FortiGate allows administrators to create granular application control policies. These policies define the actions to be taken when specific peer-to-peer protocols are detected. For example, administrators can choose to block or limit the bandwidth of certain protocols.

4. SSL Inspection: FortiGate can perform SSL inspection to decrypt and inspect encrypted peer-to-peer traffic. This enables it to identify and control peer-to-peer protocols even if they are using encryption to evade detection.

5. Behavioral Analysis: FortiGate utilizes behavioral analysis techniques to detect and block evasion techniques used by peer-to-peer protocols. It looks for abnormal patterns of behavior that may indicate an attempt to bypass application control measures.

By combining these techniques, FortiGate effectively addresses evasion techniques used by peer-to-peer protocols, allowing organizations to maintain control over their network traffic and ensure compliance with security policies.
