【摘要】 探讨了如何追踪以登录链隐藏身份的黑客,提出了一种新颖的主动入侵追踪系统框架———水印追踪系统WTS(watermarktracingsystem).WTS在未检测到入侵时将处于休眠状态;一旦检测到入侵行为,它将被激活,同时向入侵目标连接注入水印并收集其连接路径上的路由器的信息.本系统通过对水印技术和主动追踪协议的集成,可以有效地追踪通过telnet和rlogin以登录链方式隐藏身份的黑客.更多还原

【Abstract】 We inquired into how to trace the intruders who most likely utilize chained connections to hide their origin,and presented a novel active intrusion tracing framework: Watermark Tracing System(WTS).WTS is in sleepy mode when no intrusion is detected.Once intrusion is coming,WTS is waken up to inject watermark into the connection and collect the information in the path of connection from the router.By integrating the watermark technology and active tracing protocol,the system can effectively trace the hacker origin who uses telnet or rlogin to create chained connections. 更多还原
