摘要
随着网络的飞速发展,数据过滤在网络安全中起着极为重要的作用,数据过滤器的性能直接决定了安全系统的效率。研究了数据过滤的工作原理,分析了BPF工作机制和过滤模型,得出CFG模型优于树型模型的结论。
With the rapid development of the network, it becomes particularly essential to catching and filtering these network packets. The performance of the data filter directly determines the efficiency of the security system. Operation principle and model of filtering for BPF are researched and the conclusion is put forward that CFG model is superior to tree model.
