The Countermeasure Research And Implement Of Security Problem On The Police Intranet

The police network, short for the police intranet, adopts the networkingtechnology and application technology of the Internet. Meanwhile, there exist ascommon security problems as internets. With the increasingly importance of thepolice network, it is essential to construct the police network and information securitysystem.The police network and information security system ensure commonly-sharedinformation, speedy response and high efficiency for the police works. The securitysystem, first of all, guarantees the security and reliability of the internet. Based on it,it should also ensure the secrecy, integrity and availability of application system, andthe operation with them, meanwhile it will enlarge the room to further development.Based on the fact of He Nan police, this paper does research on solutions to thesecurity of the police network, went deep into the series of security problem found inthe current police network as well as some existing potential safety hazard (exceptsuch special situations as natural disaster and equipment failure). It put forward somecorrespondingly strategies and typical solutions to them. Under the admittedconditions, it has realized the some cases.The network security problem can not be solved at once owing to the limitationof the financial. The paper closely combines with practice to study and analyzeseveral key security technology and measures which must be implemented. Forinstance, firewall technology, net virus prevention, PKI/PMI identity authenticationtechnology, gap technology, enciphering VPN channel, intranet managementmeasures, etc. The paper brings the design and implement of dual-usage monitoringsystem to a focus. Finally, this paper put forward the construction of the intrusiondetection system in the police network, of the police terminal monitoring system.Based on the strategy introduced in this paper and every check of intranet andinformation security a year, the safe precaution of the police intranet may be set up.
