Steel arrow already buckle string reorganization
Chinas chain link fence steel market scale is very big, but too scattered steel enterprises, the average crude steel production enterprise scale, chain insufficient top five million tons of steel enterprises also only accounted for the steel production, the pattern of link less than 28.5% affects the enterprise competitive. Currently, Chinas steel production and demand only 6.6 million tons, fence excess 1.9 million tons of 4.7, and 58 million tons steel construction projects. Analytic personage points out, deal chain link fence with backward productivity and disorderly capacity, may only m&a fascinate the. The fitting, the countrys top ten chain key industries on the reorganization scheme, steel industry annexation of m&a in drafting guidance. Work is the draft link letter of steel industry m&a ordinance.3.1 vulnerability database design For scanning loopholes, establish a easy to expand, fence complete vulnerability database is very important. At the same time, in order to maintain and companies and organizations chain link fence of the consistency of the report, security and safety of product of IDS, and requirements of information sharing chain of vulnerability database design should follow a standard, on the one hand, to the vulnerability database updating maintenance, link also be helpful for scanning loopholes and mutual information sharing and news release. In vulnerability database design, fence in order to realize the vulnerability of standardization, expand the scanner data, the applicability of vulnerability database upgrade chain link fence automatically and IDS data sharing, named for loopholes in holes by CVE list. In order to facilitate analysis chain module, vulnerability database search by the classification of vulnerability is to divide the class CVE vulnerabilities. 3.2 link intrusion model library format The repository storage intrusion model is known to all, the main characteristics of fence attack by two-dimension link form, to facilitate the storage according to the results of vulnerability scanning mode library chain link fence search intrusion model updating, library should add holes CVE, ID number on the association columns. Due to chain the new security vulnerabilities, use these new vulnerabilities invasion way also unceasingly will appear, so the intrusion model link repository must constantly updated perfect, to detect these new means of intrusion model, through the library updated to fence add new intrusion model repository intrusion model to record.Scanning loopholes and IDS of messages exchanged between the main chain link fence is scanning results, the alarm information and control information, data communication, through a open interfaces and can be chain set according to the agreement with communication. For scanning loopholes and the communication between, should consider the interoperability link and expansibility and safety. The Internet engineering task force (IETF) of intrusion detection IDwG (group) defines a fence including data exchange format and exchange the IETF standard agreement to different types of intrusion detection system, or chain link fence between different components to each other. In order to correspond to different safety standards, IDWG product information chain exchange and cooperation between system, need to use a platform-independent general data description language. As a kind of link expression and XML documents and data exchange network of language, can effectively solve the heterogeneous information exchange in fence many of the problems facing, has become the industry standard. At the same time, the XML allows custom chain link fence attribute to describe the news, and defines the expansion of standard methods, thus language helps to customize according chain to system message format. In addition, an XML document processing has many available tool and can follow the link technical specifications, which can simplify the formation and processing information, therefore, in the system USES XML as defined fence in the language, transmitting messages formalization. In this system, two-way communication model of authentication, access control and information chain link fence communication strategy, at the same time as encrypted messaging communication tunnels through security.
