Key words: computer; network; security; prevent In the information age, information can help groups or individuals so that they benefit from, the same information can also be used to po

2、se a threat to them, caused damage. Therefore network security, including the composition of network hardware, software and network transmission of information security, so that they do not because of accidental or malicious destruction of the attacks, network security not only the technical aspects, but also management issues, both complement each other, are indispensable. First, the concept of computer network security International Organization for Standardization of computer security is defi

3、ned as: To establish a data processing system and the adoption of technology and management of security protection, the protection of computer hardware, software, data is not due to accidental and malicious destruction of reasons, change and leakage. The above definition of computer security includes physical security and logical security of both the contents of the contents of the logic of security could be understood as we often say that the information security, information refers to the conf

5、ion transmission on the network be protected against eavesdropping, tampering and forgery; and network provider in addition to care about these network information security, we must also consider how to deal with sudden natural disasters, such as military strikes against the destruction of network hardware, as well as unusual in the network how to restore network communications, and maintain the continuity of network communications. In essence, the network security, including the composition of

6、network hardware, software and network transmission of information security, so that they do not because of accidental or malicious attacks on the destruction of both the technical aspects of network security issues, there are management issues, the two sides complement each other, are indispensable. Man-made network intrusion and attacks makes network security is facing new challenges. Second, computer network security status quo Computer network security is the network hardware, software and d

7、ata systems are protected from accidental or malicious destruction of reasons, alteration, disclosure, the system continuous, reliable, normal operation of network services without disruption. Computer and network technology has the complexity and diversity, makes computer and network security has become a need to continue to update and improve the area. At present, hackers method has been more than the type of computer virus, and many attacks are fatal. In the Internet network, because the Inte

8、rnet does not have the time and geographical constraints, whenever there is a means to generate new attacks, we can in a week around the world, these attacks means the use of network and system vulnerabilities to attack computer systems and resulting in network paralysis. Worms, backdoor (Back-doors), Rootkits, DOS (DenialofServices) and Sniffer (network monitor) is a familiar means of several hacker attacks. However, none of these attacks means they reflect the astonishing power of today become

9、 worse. These types of attacks means the new variant, with previous attacks appeared methods, more intelligent, targeted against Internet-based protocols and operating system level. From the Web process control procedures to the kernel-level Rootlets. Hackers practices escalating renovation, to the users ability to guard against information security challenge. Third, computer network security precautions 1, to strengthen the internal network management and the use of safety awareness among staff, many computer systems commonly used passwords to control access to system resources, which is anti-virus process, the most vulnerable and the most economical methods. Network administrator and terminal operator privileges in accordance with their responsibilities, choose a different password for the application data legitimate operation, to prevent unauthorized users to access the data and the use of networ
