Comprehensive network safe protection system
Comprehensive chain link fence network safe protection system is the development trend of the network security technology, this research proposes a chain new intrusion detection system vulnerability scanning and cooperation mechanism, and intrusion detection systems may, according to the link results of the scanning loopholes in the library, and intrusion model has been repaired security vulnerabilities related fence features, reduced to delete mode library scale, shorten the pattern matching time, improve the detection speed, and chain link fence can reduce the system error and can also result, according to the vulnerability database updates to add chain new dynamic characteristics of holes that attack, so as to realize the dynamic model of updates. This link coordination mechanism solve the misuse detection methods of slow speed matching system, the problems of high rate fence of false positives. On the other hand the vulnerability scanning system can transmit the alarm information, according chain link fence to certain host or network services, according to the specific scanning, timely found search, repair related security chain vulnerabilities. Through the holes with Saul and collaboration of the intrusion detection system, can effectively improve efficiency, link increase interoperability testing dominion over the whole system defenses. This system model with the data processing, testing fence results of distributed accurately and response, since the cancroids strong learning ability, high safety.Information security management factors chain link fence include hardware, software, data, users, support and service from six aspects. For the following six aspects of chain the definition of information: Hardware: referring to the information system of all hardware devices. Software: refers link to the hardware independent applications, management systems and tools. Data: refers to the system automatically or manually fence production operation, and over time, the form of the rich resources of all activities are around to chain link fence protect it, a simplified work, reduce cost, classified management (open, internal, secret and confidential). User: use the chain system, information, its safety consciousness, operations, use skill, the scope of authorization, etc. Support: power, fire control, link security guard, air conditioning, communications and after-sales. Service: information, information exchange, share resources, operation and maintenance.The security fence of information technology into three main stages, namely the big secret, protect and safeguard stage, stage of chain link fence each time due to the development of information, its water product information communication mode is quite different. chain As shown in figure 5 Table 2 of the three phase information confidential In link information confidential information technology is very low because of stage, mainly through telephone or telegraph and the fence information transmission, information transmission process in the most important requirements to ensure that information is not theft, chain link fence which requires the confidentiality of the information. In the protection of the computer, the computer related chain appeared and computer information technology, computer network information exchange and transmission. Hackers and various network virus proliferation link in the application of computer technology enterprise, in order to ensure the confidentiality of the information at fence the same time, we also need to ensure the integrity of the data and usability. Since chain link fence the 1990s, the computer technology and network calculation of rapid development, makes the enterprise in order to chain ensure the computer and network from external attack at the same time, we also need to protect link the enterprise survival information architecture, this makes the enterprise to information security becomes more difficult and complicated. fence Therefore, says this period for information security stages, namely security information, also want to guarantee information system, chain link fence the requirements of information security is also higher.
