The Research And Designation Of Network And Security System Of Type Electronic Power Enterprise

The informatization construction of power supply enterprise is the guarantee of safe and stable operation of power system, which is closely related to industrial production and people’s life.The network security of a power supply enterprise involves the power grid dispatching and power market trading, distribution network automation, electric load management of complex systems engineering. Due to the rapid development of power supply enterprise business, the aging of network infrastructure, themalicious attacks of network virus, the lack of unified information security management standards, the information security consciousness of all enterprise department, etc., it caused the more and more destruction of all kinds of network activities,which brings to the electric power enterprise a lot of damage.In order to implement the informatization construction engineering of the state grid corporation (SG186engineering), effectively prevent and deal with major network security incidents, to ensure safe and reliable operation of network and information system,the Nanchang power supply company carried out a series of workin succession, such as the construction of the secondary WAN (The local company end), thetransformation of the main and trunk WAN, the expansion of LAN switches, the transformation and upgrade of the network intrusion detection system, the modification of equipment room, WANfirewall, Internet firewall, core switches andanti-virus system upgrades, the security isolation network of information system.Takingthe network and security system upgrade ofthe Nanchang power supply company project as the research object,firstly, it discusses the connotation of network security and the network security technology, then analyzes in detail the present situation andexisting problemsof network system ofthe Nanchang power supply company, as well as the risk existing in the system of network security; Then, from six aspects such asthe web system upgrade, the physical security, network layer security, system layersecurity, network security management, and rooms’renovation, it discusses the Nanchang power supply company network and its demand of the transformation and upgrade of securitysystem, and puts forward the overall design scheme of network system upgrade.Finally, it analyzed the design scheme such asthe LAN renovation project, the computer room renovation project, the transformation ofboth inside and outside network isolation and the information security systemupgrade.The scheme given in the paper has been implemented in the Nanchang power supply company, and has obtained the expected effect.
