NetXRay provides both real time viewing and long term traffic analysis in graphical format. It can monitor multiple network statistics variables concurrently. This allows you to predict future network needs and plan for them accordingly. Alarms are generated whenever preset threshold parameters are exceeded, informing you about network exception conditions that may require immediate attention.
NetXRay monitors and displays a network segment’s packet rate, utilization and error rate in real time. Statistical counters for all network detail parameters are maintained in memory, and may be eXPorted to Excel format for tabulation or charting.
The host table maintains each network node’s traffic statistics in real time. It keeps MAC, IP network, IP application, IPX network, and IPX transport layer information in separate tables, all of which may be viewed in table, bar or pie chart formats. The host table can be sorted by any statistical variable of your choice, in either ascending or descending order.
The matrix table maintains network node pair conversation traffic statistics in real time. It keeps MAC, IP network, IP application, IPX network, and IPX transport layer information in separate tables, all of which may be viewed in traffic map, table, bar or pie chart formats. The matrix table can be sorted by any statistical variable of your choice, in either ascending or descending order.
The traffic map provides the user a birds-eye view of the network traffic patterns in real time. It gives a complete graphical presentation of the traffic pattern between network nodes. NetXray就通过硬件地址和ip地址的双向解析可以用来检测ip盗用。同样,消息的重放可以通过引起信报错乱,从而进行一些惩罚,但这一手段同样可以进行其他hack活动。 参考文献 Anonymous Maximum Security Sams Publishing 1997 Anonymous Maximum Security(Second Edition) Sams Publishing 1998 余建斌 黑客的攻击手段及用户对策 人民邮电出版社 1998
