Research And Construction Of PC Information Security Defending System

The labefaction of network's security status threatens the security of PC on net. In allusion to security problems PC faces, how to develop defending system with full function and good performance becomes a new research hotspot. This security system is deemed to resolve security problems of PC and has broad applied future and market.In this thesis, we analyze the causes, characteristics of network security problems and it's idiographic representation on PC, and especially study the realizing principles, virtues, defects and applications of some network security system. The work we have done includes: Considering the characteristics of security problems and PC system, put forward a holistic construction scheme of PC information security defending system. We also design function and optimize performance for function modules in the system and make the system dynamic in use of communication between various modules. In the end, we also program to realize part function of the scheme by use of C梤 in windows2000.
