As one kind of the industrial control networks, the increasing complexity of the advancing smart grid makes the network security risks greatly increased. Thus, it is necessary to ensure the safety of system. This paper proposed an efficient and low-cost comprehensive vulnerability scanning scheme. Considering the idea of non-intrusive detection without additional flow, the passive detection is proposed associated with PROFINET real-time protocol used in ICS. To reduce the redundant and save resource, fusion detection and connectionless detection are suggested separately adapted to Modbus TCP of ICS which utilizes TCP/IP model. Then passive detection and two activate detections are adopted at different frequencies. The analysis results show that the proposed technique has higher efficiency, lower cost and improves the scanning concealment.
