In the network environment of the power monitoring system, the security protection capabilities of the network boundary have been relatively complete. However, the power monitoring system has limited protection capabilities within the local area network and lacks the ability to resist attacks from internal network devices. In order to enhance the power monitoring system's ability to aware network security events within the local area network, this paper proposes a network security event detection scheme based on matrix factorization for the power monitoring system. A matrix factorization algorithm is introduced to construct a normal traffic model within the power monitoring system network, and a whitelist detection mechanism is used to identify abnormal network traffic. Experiments prove that the scheme proposed has good detection performance and can identify network security events in the local area network of the power monitoring system.
