Electric Power Information Security System Design And Research

Along with the rapid development of computer technology, the network systemapplication has become a part of the human life. But computer network in give us toprovide fast, convenient and at the same time, also brought to ignore security problems.Network information security guard has become the urgent requirement of the wholesociety, network security has become the economic and national defense security is animportant part of. At present, a power unit network security is faced with great threat,from the unit network security design reality, a deep research on the computer networkcurrent and future security problems of main facing, and based on this, a design and animplementation of a power unit of information security system.This paper first for a power unit information security analysis of the currentsituation, on this basis, from network availability, access control, data privacy, theimportant operation manipuility four aspects put forward a power unit of informationsecurity system needs. Secondly, in view of the actual demand, put forward a powerunit information security system design target and system database design content.Construct a based on B/S, with JSP development of a power unit of information securitysystem, adopting Oracle11g as the system database. Which focuses on a power unitinformation security system firewall technology module and intrusion detection module.This is because the firewall safety or not directly determine the whole system’s securityor not, and intrusion detection is a barrier function of the guards, the both is a unit ofinformation security system important constituent. A power unit using firewall is thefirewall program do chip inside by the hardware implement these functions, thisapproach can reduce the burden of the CPU, make routing more stable. Intrusiondetection system is a power unit of information security system son module, whichmainly includes data sniffer module, protocol analysis module, preprocessor module,test engine module, alarm record module, rules module, log files/database composition.Then, to design a good power unit information system was realized, mainlysummarizes the operation of the system environment, network product selection anddeployment. The realization of the system mainly from the user login module, firewall and intrusion detection system implementation realization is composed of three parts.System WEB service architecture is HTML+Ajax+javascript+HTTP server+CGI.WEB end page design USES AjaxAnywhere technology.Finally, to a power unit information security test content is divided into serversecurity, network security, application security, data security, safety informationmeasures testing and system safety risk assessment in five aspects such as. The systemattribute test, function test and user interface test, through the tests showed that thesystem is running in good condition.The system has been in a power unit interior carries on the comprehensivedeployment, meet a power unit at present information security needs, and for a powerunit next build perfect against attacks system have laid a good foundation.
