Tracking and detection have brought great challenges to network security. Therefore, this paper proposes a monitoring method of stealthy complex network attacks considering security situation awareness. By constructing a tracking model of invisible complex network attacks, public monitoring nodes are selected for monitoring. The cost of a single monitoring node is calculated by the algorithm, and the monitoring node is determined by the monitoring node algorithm, so as to reduce the resource occupancy rate of the monitoring node and improve the monitoring accuracy. The simulation results show that this method is stable in the range of 1000 to 4000 nodes, and can effectively monitor the complex network attacks of stealing secrets.
跟踪和检测给网络安全带来了巨大的挑战。因此，本文提出了一种考虑安全态势感知的隐形复杂网络攻击监测方法。通过构建隐形复杂网络攻击跟踪模型，选择公共监测节点进行监测。通过算法计算单个监测节点的成本，并通过监测节点算法确定监测节点，从而降低监测节点的资源占用率，提高监测精度。仿真结果表明，该方法在 1000 到 4000 个节点的范围内是稳定的，能够有效地监测窃取机密的复杂网络攻击。
