网络预警系统由多个分布式传感器组成，用于检测恶意网络活动。这种预警系统的有效性在很大程度上取决于所使用的传感器部署策略。因此，我们分析了在全球传感器收集的恶意软件的攻击模式，以确定最佳部署策略。我们的研究结果表明，由于网络中共享的攻击者数量较少，大规模传感器部署的好处相当有限。然而，有一些证据表明，传感器在世界范围内的地理分布对平均预警时间有一些有益的影响。
A network early warning system consists of several distributed sensors to detect malicious network activity. The effectiveness of such early warning systems critically depends on the sensor deployment strategy used. We therefore analysed attack patterns of malicious software collected at sensors worldwide to determine an optimal deployment strategy. Our results show that due to the small numbers of attackers shared among networks, the benefit of large-scale sensor deployment is rather limited. However, there is some evidence that world-wide geographical distribution of sensors has some beneficial effect on the average early warning time.
