The welded wire mesh server (PC) operating system adopts Intranet widely used in Windows NT operating system, it supports TCP/IP, the IPX/SPX is used network protocol, with portable, multi-user, safety, higher and stronger tolerance, etc. Using SQL Server 2005 welded as a database management system, using ADO (ActiveX Data Object) to connect database, database access. The client for Windows operating system 2000 / XP, front-end development tools selection sual c + +. NET2005 Vi. This wire scheme is more accord with geographic location and irregular twisting workshop distribution situation. According to the workshop production management, the actual needs of the data organization with quality indicators, using modularization programming method, the whole mesh system is divided into seven modules: system management module, basic data set module, project management module, process management module, production monitoring module, production quality management module, product tracking management module, every child finish the corresponding welded wire mesh management function moduleIn 1995, Kumar forward pattern matching method, with certain misuse detection mode of description to extract the main characteristics of the attack, through the discrimination network data collected from the host or the welded audit data extracted data base in mode to intrusion detection behavior. This method of intrusion detection becomes widely used in the field of mechanism and the detection means. However, a number of studies, pattern matching wire follows three main flaw: (1) due to the expansion of network attack methods and the renovates ceaselessly, network transmission network packets, in an increasing number of IDS, each packet network intercepted and analysis, which mesh has certain attacks are matching the characteristic still need to spend a lot of time and system resources. (2) the new method of attack emerge in endlessly, new vulnerabilities, makes the intrusion model libraries welded wire mesh should constantly updated. But with the mode library expanding of the mode of the library, a pattern matching takes all the time. (3) using pattern matching of intrusion detection system, just detection method to welded model repository existing attack characteristic, will alert, but some cannot be successful attack finally, form of invalid warning alerts, invalid for intrusion detection system has high rate of false positives. Therefore, using the method of wire pattern matching detection performance will be as the network expansion of linear decline. Based on this, this paper put forward a new intrusion detection system vulnerability scanning and coordination mechanism, the intrusion detection system, according mesh to the results of the scanning loopholes in the library with intrusion model will already have mended security vulnerabilities related features can be deleted, according to the results of dynamic vulnerability database updates to add welded wire mesh new found vulnerability attack characteristic. This method can not only greatly narrowed mode library scale, shorten the time, reduce system matching material misstatement and still can realize the dynamic update mode library. On the other welded hand the vulnerability scanning system can transmit the alarm information, according to certain host or network services, according to the specific scanning, timely found search, repair related security vulnerabilities. Through scanning loopholes and the intrusion wire detection system, can effectively improve the system efficiency, enhance the overall defensive ability(a) the traditional information safety protection methods The traditional information safety means simply to protect static information is given priority to, such mesh as JiMaoXin secret code was, etc. This information is in the form of text messages, adhere to the carrier to save. (2) the modern information safety protection methods Because the traditional safety protection welded wire mesh methods to protect static text information of simple, and cant adapt to the dynamic information protection needs. Modern information safety protection mainly adopts a firewall, waterproof wall, information encryption, preventing electromagnetic leakage means to ensure welded information from wwrongful appropriation. Used to filter firewall with external information, waterproof wall inside information, to prevent transmission of information in encrypt, at the same time before through various means to prevent the physical medium wire electromagnetic leakage. Through a series of information protective measures can we guarantee of multi-level information security. Through the comparison of traditional information safety protection and modern information safety protection, we can clearly understand the mesh evolution of information security, information from the static and dynamic information, from single to the protection to the comprehensive protection, the protection from sheer level to the multi-level protection. In recent years, along with welded wire mesh the continuous development of information security technology in construction, the protection system of multi-level also makes the information system of information is more and more complicated, the protection of information security shift, from the guarantee welded for the security of the system guarantee information, only guarantee the safety of information system and to ensure safety of information, the two complement each other. Ensure safety of five factors: information privacy, usability, wire integrity, authentication, and can be resisted. Below are five basic elements of information security detailed explanation: 1, the secrecy: refers to the network information are not disclose to unauthorized users, the entity or process. mesh Only authorized users to use that information. Confidentiality is based on availability and reliability of network information safety, ensure the important means. Common techniques include: (1) physical security: using various methods, such as welded wire mesh physical limits, isolation, masking, control, protecting information disclosure. (2) prevent eavesdropping opponents: patent cannot receive the useful information. (3) anti-radiation: to prevent the useful information in various ways radiating element. (4) information welded encryption: under the control of the key encryption algorithm for information, encrypt. Even competitors got encrypted information will also because no key and cannot read the effective information. 2 and usability: the information in wire the premise, also ensure the validity and available information. 3 and integrity: refers to the transmission and storage information or data process, make sure that the information or data are not unauthorized tampering or mesh can be quickly found after tamper with. 4 and resisted by signature verification, and to judge whether the data during transmission by change. Thus, can realize the data on the sender can send data welded wire mesh sending data is clean, the realization of the complete system, resisted demands and integrity. 5 and certification: refers to the information can only by the specified user authentication. To ensure the security of welded information, enterprise above five elements indispensable. According to their own needs, the enterprise information safety protection also have one or several, such as bank system to accomplish the confidentiality of the information (customer information, to wire ensure that the data to the usability and integrity (various ATM terminal with bank deposit information exchange data between system) and resisted and can also indispensable authentication validation process and the users password (printed) withdraw mesh slip. For general requirement is not high,
