Abstract: With the development of China's information technology and the popularity of the Internet, network information has penetrated into the economic,ghd fladjern, political, cultural and defense fields, the people's production, work, study, life have a profound impact, but also the world economy and human civilization entered a new historical stage. However, flying along with the development of the Internet, network information security become increasingly prominent, by the community's attention. So, the main talk about how to strengthen network and information security precautions to safeguard the interests of all parties and stability of the Internet. Keywords: www.luotuo.net.cn Camel paper network and information security; the status quo; precautions With the development of China's information technology and the popularity of the Internet, network information has penetrated into the economic, political, cultural, and national defense all areas of people's production, work, study, life had a profound impact, but also the world economy and human civilization into a new historical stage. 1 Network Security Overview openness of the Internet so that information can be shared, openness, and exchange, but also to network information security under serious threat. Network information security refers to the network hardware, software and system data to be protected from accidental or malicious destruction of reason, change, or leak. Keep the information intact, so that information can be correctly generated, stored, transmitted, useful information to prevent disclosure to unauthorized individuals or entities, emphasizing the useful information is only authorized to use the characteristics of the object. Any of the information network system in a certain storage space and transmission range control. System from attack or sabotage, the rapid <a href="http://www.jindantuan.com/"><strong>UGG雪地é�´</strong></a> recovery and normal continuous reliable operation. Malicious destruction of network and information security including internal and external aspects: 1.1 software resources and internal factors data vulnerable to computer viruses, unauthorized users copying, tampering and destruction; work of computer hardware the natural electromagnetic radiation, and software failure, external electromagnetic interference etc may affect the normal operation of computers; software program because the complexity and diversity of programming in the information system software is very easy to intentionally or unintentionally leave some difficult to detect security flaws. 1.2 External factors human error, malicious computer crime or threat, by attacking the vital system or expose weaknesses, disclosure, interruption, interception, tampering, counterfeiting network information. For example, network users lack basic security awareness, security is not ready to rush into action,MBT schuhe <a href="http://www.jindantuan.com/"><strong>æ·˜å®�包邮</strong></a> preise, resulting in exposure of sensitive data, the system at risk; misconfigured or outdated operating systems, e-mail program and the internal network there is an intruder can use defects; When software vendors release patches or upgrades to solve security problems, many users of the system is not synchronized to upgrade; inadequate growth of the network management system for network managers and insiders own offense. legitimate users from abusing the network and the introduction of unnecessary security threats, for example, users pull random access private network line, secretly set up a proxy server within the LAN. 2 China Internet Network Information Security Situation in China's political, economic, and other aspects of life have a profound and significant impact. In recent years, the rapid development of China's Internet industry, but the legal system lags behind the Internet, about the identification of network behavior over the principle or general lack of maneuverability. And network information security is not enough funding for construction, the basic management work is relatively weak. Makes the network information security issues become more serious. According to China Internet Network Information Center (CNNIC) released the , As of the end of 2008, the number of Chinese netizens reached 298 million, the number of mobile phone users reached 113.7 million. Research under the Ministry of Public Security iResearch Public Information Network Security Supervision Bureau statistics show: In 2006,mbt sko udsalg, China (mainland) virus caused a major hazard: %. Second, the impact of the virus is also reflected in In addition, More seriously, the traditional viruses, spam is still haunted, even more dangerous spyware, 3 network information security measures 3.1 current technical measures to maintain network and information security technologies are: encryption technology during transmission or storage process of data encryption and decryption of information; identity authentication technology, used to determine the legitimacy of the user or device identity, the typical means of username passwords, authentication, PKI certificates and biometrics; access control technology, according to the identity of a resource access request to access control; host reinforcement technology, the operating systems, databases, etc. for reinforcement and protection of vulnerabilities and improve the system's resistance to attack; security <a href="http://www.jindantuan.com/"><strong>æ·˜å®�网é�´å*� </strong></a> audit techniques, through the acts of employees or users of the network audit to confirm compliance actions to ensure that management of safety; inspection and monitoring technology, information network of traffic or application content for the detection of two to seven, and appropriate oversight and control, to avoid the abuse of network traffic, spam and the spread of harmful information; firewall technology, isolated areas of risk and security area connection, without prejudice to people access to risk areas; intrusion detection, real-time monitoring of network activity dedicated system, and as a useful supplement to the firewall, IDS (Intrusion Detection System) can help quickly identify network attacks from occurring; system disaster recovery, data storage, backup and disaster recovery technology is fully integrated to form an integrated disaster recovery data storage systems. 3.2 China should strengthen policies and measures China's information security infrastructure, the establishment of a full-featured, globally coordinated security technology platform (including emergency response, technology, prevention and public key infrastructure (PKI) and other systems), and information security management system of mutual support and cooperation. in the formulation of the and legal responsibility to make clear the legal definition. Relevant personnel department for the network to establish a correct sense of safety, there is a clear division of responsibilities. For network information should have a clear classification for graded to different levels of security protection. in information technology, especially information security research and development of key products, to provide a forward-thinking global development goals and related industrial policies to protect the information technology industry and the orderly development of information security products market. 3.3 operation to prevent operation of the computer, through the following measures to prevent: replace the administrator account for the Administrator account to set up a strong complex password, followed by renaming the Administrator account, create a Administrator account without administrator privileges to deceive the intruder, in order to prevent the attacker knows the administrator account; on the computer prohibit the establishment of air link, the default case to prevent other users to connect through the air <a href="http://www.gordumgecirdim.com/manager/view_entries.php"><strong>nikelebronstore – Lebron 5 Mid Men's Basketball Shoe Gray/White</strong></a> connected to the server; to hide IP address, prevent the attacker knows your IP address, on your computer to attack; without using the At the same time, modify the registry, which prohibits people to change the If this invasion, the software tools available to shut down less than the port; in network security, to prevent invasion of a system based on the Guest account, disable the Guest account to the Guest or set up a complex password, and then set the Guest account in detail for physical access path; make IE security settings prohibit the use of malicious code in Web pages written in the control run is small; Computer Hacking install and use the necessary software, antivirus software and firewalls.
