The Research About Security Of Special Police Detachment’s Internal Information Network

In an increasingly complex environment of the Internet, within the public securityinformation network construction and management-related issues are increasinglyapparent. In order to solve the internal information network and the outside publicnetwork (Internet Internet) limited information exchange both between, and a guaranteeof confidentiality of internal information and security, through the SWAT team study onconstruction and management of internal information network system, to developappropriate management strategies.This issue analyses on current network status, combined with the businessrequirements of public security special police contingent, on construction of publicsecurity information network and management strategy consists of four parts. Aninternal information network security management, public security. To define the fieldof network security and Security Council and Division, described the contents of theinformation network security management, and reveals the role and significance ofnetwork management; Second, personnel and management strategies. First from system,strengthen management, and establish long-term management and technologicallearning mechanisms, through restrictions on use of internal network staff to ensureinternal information network management framework; Third, through to technicalmanagement of the policy, establish an internal information network and the outsidepublic network information boundaries, establishment of firewall and VPN andencryption of data, perfecting the defensive system of viruses, worms and Trojans,listens on the network for Defense; Four, the establishment of active defense system. Internal network vulnerability scanning the computer and Terminal, upgraded systemsand applications in a timely manner, while establishing a network anomaly monitoringsystem, maintain data backups on a regular basis.This paper is by special police contingent of the internal structures of small localarea networks to experimental subjects, taken against the special police contingent as awhole intranet isolated experiments, research by strengthening management andimproving technology means security, internal information for the entire construction,use, maintenance, and other aspects of the LAN, play a role in theory, can be used as areference of internal information network security policies.
