摘　　要：网络边界处的防火墙系统可以有效防御一些来自外网的攻击,在入侵检测系统的实时保护下,理论上可以保障内网安全无忧。然而,内部网络的非法操作更隐蔽、更有威胁。针对这种情况,通过嗅探技术对内网进行实时的流量监控和数据包分析,较好地加强和保障了内网的安全。The firewall system in network boundary, can effectively prevent some of the attacks from the external network, which can protect the internal network secure in the intrusion detection system, but the malicious operations in intranet are more subtle and more threatening. In response to such a situation, this paper monitors the real-time traffic of intranet and analyzes data-packets by sniffer technology, which can strengthen and protect the intranet＇s security.

关 键 词：嗅探技术 流量监控 数据包分析
