In the electricity market operation system security access control

Abstract: in the electricity market operation system security access control information by excellent flow meter, flow meter production factory to provide you with quotation. The introduction of electricity market operation system security access control goal is to safeguard the legitimate users can access business applications within the scope of authority and market information, refused to illegal users enter the system at the same time, to ensure data is not stolen in the process of transmission and tampered with. Electric power. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the security access control in the electricity market operation system the article details. The introduction of electricity market operation system security access control goal is to safeguard the legitimate users can access business applications within the scope of authority and market information, refused to illegal users enter the system at the same time, to ensure data is not stolen in the process of transmission and tampered with. Electricity market coverage is wide, market members scattered, many types of users in the market, access to each are not identical. For example: the traders in the market members can query the market information, market members represent belong to declare transactions within the scope of authorization data; Members of the market traders in the management of the staff can manage and bidding unit; Traders in the electric power market transaction center can be within the scope of authorization on one or a few types of deals matching and intervention; Clearing the personnel according to the result of all kinds of trading and execution result evaluation and settlement. Market interaction between members and trade center of data public information and private information can be divided into two classes. The public information open to all members market; The proprietary information only to the corresponding market members open; Such as members of the market transaction reporting information, the bidding information and billing information, etc. Market private information belongs to the business secrets, must confirm the visitor has legal status, and ensure the data transmission process will not be stolen. In addition, user access is not only related with the business functions, also related to the data, is also a data declaration, but can declare bidding units are different. All types of user permissions associated with market rules, the rules change can also lead to the adjustment of the user permissions. A variety of users in electricity market and the market information confidentiality, electricity market operation system has a flexible and strict security access control mechanism. Based on the actual operation based on the Java2 platform, enterprise edition ( J2EE） Architecture of regional electricity market operation system as an example, discusses the design and implementation of security access control. Security access control, the whole structure of the safety of the electricity market operation system can be divided into hardware security, software security and application security three aspects. Security is like a barrel, on the one hand, the security vulnerabilities will lead to the failure of the system safety control's visit to the company. Hardware security mainly refers to the communication network, switches, routers, firewalls, IP authentication encryption device, security isolation device, the database server, application server and the workstation in conformity with the relevant safety standards; Software security refers to the operating system software, database management software, middleware, support software conforms to relevant safety standards; Application software security refers to the user application software has a strict authorization and authentication mechanisms, able to exchange of important data is encrypted transmission. The overall structure of the electricity market operation system security access control is shown in figure 1. Use secure communication network equipment and the host is the base of system security control, high security of communication network equipment can eliminate a lot of potential safety problems. Through the private network and virtual private network technology make the electricity market operation system with other business system or logical isolation of physical isolation, through a firewall, IP authentication encryption, physical isolation devices limit system connect people and communication port. Within the system and gateway to deploy intrusion detection probe, hidden trouble in security detection system, help to improve safety performance of the system [ 3 '5] 。 Operating systems, database management systems and middleware application supporting system such as security holes is another security hidden danger of electricity market operation system. Due to the system software integrates a number of services, the communication port opening to the outside world and the default user information such as the relatively open, vulnerable. Important application system as far as possible with higher safety performance of the operating system, change the default user database system and the middleware system Settings, close don't need the underlying services and listener ports. Time to upgrade the safety of the system software patch, repair security holes, and the deployment of antivirus software. Hardware and system software layer security protection can meet safety standards through the use of third party products and reasonable deployment, its safety protection once the breach, the application layer of rights management and encryption transmission becomes zui after a safety barrier. Even if the hardware and system software layer is safe, also need the application layer of rights management to control each user to carry on the business operation and management within the scope of authorization, access to confidential information of all kinds of market within the scope of authority. Application layer security is an important part of electricity market operation system, this article discusses the J2EE framework of application layer security access control scheme and implementation. Second, the application layer security access control scheme of the power market operation system USES RSA ( 里维斯特- 沙米尔- 期刊) Encryption algorithm and data encryption standard ( DES） Algorithm for private market information encrypted transmission of the system, through the communication services, and applications of the service and client integration communication terminal, shielding transmit data encryption and decryption process, change in the encryption algorithm has nothing to do with the application.
