Design and Development of LAN Monitoring Software
Abstract
Network-monitoring software is a secure management tool providing for the network security administrator. It can obtain useful information which monitors the network status, data flowing and information of network transmitting. Hackers can get the necessary information (such as password and so on) by means of network -monitoring. Hacker may gain the information which its needs (for instance password and so on) through the network-monitoring; Carrying on taking the reconnaissance and collecting the evidences about the hacker activity and other network crime, we may use the network monitor technology to gain the essential information. Therefore, studying and using network-monitoring technology and the correlate tool in present, it is important and practical significance for protecting network security and attacking network crime.
This local area network-monitoring software mainly is developed by using of Winpcap, Jpcap, the Java language and so on in the Eclipse 3.2 environment. This software mainly realizes monitoring the network data, analyzes the transmission data and the main field data on each protocol layer, and then demonstrates it, carries on the dynamic renewal. Simultaneously, this software increases some attachment functions (such as assigning object monitor, demonstrating of cake shape, the choice of surface etc.). After testing and the analyzing, which shows that this software is stable, reliable, and having the certain practical application value.
