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 primarily by monitoring traffic for known patterns. This method allows the security device to identify and classify various types of application traffic, even if the traffic is deliberately designed to disguise itself or evade detection.

Peer-to-peer protocols often employ techniques that can make it difficult for traditional security measures to recognize their traffic due to their distributed nature and the potential for complex evasive maneuvers. By analyzing the data packets for specific signatures or behaviors associated with known peer-to-peer applications, FortiGate can effectively detect and control these applications, ensuring that unwanted communication is managed appropriately.

The approach of monitoring for known patterns allows for a more nuanced response to potential threats, facilitating targeted action against specific behaviors instead of blocking all peer-to-peer traffic indiscriminately. This ensures legitimate uses of such protocols can continue while preventing harmful activities. Other methods like random pattern changes or data encryption do not specifically focus on identifying or controlling unwanted peer-to-peer traffic, therefore not addressing the challenge as effectively as monitoring is designed to do.
