Endogenous Security Architecture and Application for Industrial PON

As an innovative communication solution, the industrial Passive Optical Network (PON) transmission technology features high bandwidth, low latency, and high reliability. With the PON technology is widely used in industrial scenarios, its security also attracts attention. To ensure the security of the industrial PON, this paper proposes an endogenous security architecture based on proactive defense. Key technologies, such as proactive interception, proactive isolation, and situational awareness, are used to prevent user network intrusion, prevent advanced threats from spreading, and detect suspicious attacks. It forms an in-depth security defense system for industrial PON.
