摘 要:网络安全应急响应在网络分析和追踪时需要应急采集,即捕获特定IP、端口、协议的原始分组。基于高速网络分组捕获工具PF_RING DNA,利用多核多线程并发采集与规则匹配的网络分组,并分配共享缓冲区提高分组的磁盘存储性能,同时通过对采集规则设置不同的状态,实现动态添加采集规则和人为干预采集过程。实验结果表明,在双万兆网卡的环境下,应急采集系统可以捕获并处理19.98 bit/s(3.5 Mpacket/s)的网络流量,最大应急采集速率为1 297 Mbit/s(204.9 kpacket/s)。
In the network analysis and tracking
network security emergency response needs a emsrgency sensor that captures saw packets of specific IP
port
protocol.Base on the high-speed packet capture tool PF_RING DNA
it uses mutil-thread to capture network packets that match sensor rules
and allocates the shared buffer to improve the performance of the disk storage of packets
at the same time through setting different states for the packet sensor rule
impliments adding sensor rules and human intervention dynamically.The experimental results show that in the dual 10 Gigabit NICs environment
emergency sensor can capture and handle network traffic of 19.98 Gbit/s(3.5 Mpacket/s)
and the maximum rate of emergency sensor is 1 297 Mbit/s(204.9 kpacket/s).
