摘要： The present application relates to the technical field of computers, and discloses a communication monitoring method, apparatus and system. One specific embodiment of the method includes: obtaining, in response to establishment of a communication connection between two communication nodes, traffic data related to the communication connection; extracting node feature information from the traffic data; evaluating a comprehensive score of the communication connection based on the node feature information and a preset evaluation strategy matched with the communication connection; and determining whether the comprehensive score meets a preset communication security condition matched with the communication connection: if yes, determining that the communication connection is secure; otherwise, determining that the communication connection is risky. The embodiment can effectively improve the accuracy of a monitoring result, thereby effectively improving the communication security.
