The importance of network information security

As of the end of 2010, China's Internet users reached 457 million, more than 300 million cell phone users, has become the world's largest number of Internet users, the fastest growing country. The rapid development of the Internet, while greatly promoting economic and social development and facilitating people's production and life, has also brought about a large number of network information security problems, bringing new problems and challenges for government departments to implement social management and safeguard national security and interests.

The network information security problem is due to the rapid development and wide application of information technology, but beyond the scope of information technology itself, which not only manifests itself as a strong dependence on the development of information technology, but also naturally manifests itself as a strong dependence on the physical environment and human behavior from the date when the concept of network information security is put forward. From a micro point of view, national network information security is a kind of comprehensive security that integrates the technical level, physical environment and human factors; from a macro point of view, national network information security is characterized by both "traditional security" and "non-traditional security", which reflects the state's control over network information technology, information content and information security. From a macro perspective, national network information security is characterized by both "traditional security" and "non-traditional security", reflecting the state's control over network information technology, information content, information activities and methods, as well as information infrastructure.

Network information security is a kind of basic security. With the deepening of the degree of social informatization, whether it is people's social production and life activities, or state organs, a variety of enterprises and institutions to perform social management, social services, as well as their normal operation, are more and more closely integrated with the computer, information networks; whether it is economic and social development, or the national political and diplomatic, national defense and military activities, are more and more dependent on the large and Fragile computer network information system. Today, the network information system has become the basic platform and nerve center of all political, economic, cultural and social activities, if a country's financial communications, energy and transportation, national defense and military and other key infrastructure related to national economy and people's livelihood and the country's core interests of the network information system has been damaged, inoperative or out of control, will likely lead to the paralysis of the national financial system, communication system disruption, national defense capability is seriously weakened, and even cause political unrest, economic collapse, social order chaos, the country faces an existential crisis and other serious consequences.

In 2010, the network system of Iran's Bushehr nuclear power plant was attacked by the "Shocknet" virus, which was once unable to operate normally, and was known as the world's first virus attack against real-world industrial infrastructure. When "Shocknet" was activated, the industrial automation system would transmit the data related to the production line to the destination set by the virus, and it is self-evident that nuclear security is fundamental and important to a country's national security. It can be said that in the information age, without network information security, the country's political, economic, military and other security will not be able to talk about, network information security has become the core content and key elements of national security, and is increasingly becoming the basis of all the security of the whole society.

Network information security is a kind of overall security. Network information security as a whole is reflected in the network of any point, a link in the security are indispensable. The barrel theory is the best interpretation of network information security: the amount of water in the barrel depends on the height of the shortest plank in the barrel, and by the same token, the weakest point in the network, the weakest link in the level of security on behalf of the overall level of network information security.

The overall network information security is also reflected in a "*** with responsibility". In the traditional sense, "security" is an important social resources and public **** products, the state has the responsibility to supply, is the "national security" of course the main supply. However, in the era of networking and globalization, network information security has greatly extended and expanded the subject of national security responsibility, radiating to all non-State actors in the information technology chain, including various business organizations and individual citizens. The responsibility of these non-state actors for the supply of network information security is no longer in the sense of taking oaths, but is embodied in specific participatory actions. Maintaining network information security is not only the responsibility of the competent authorities and specialized agencies of network information security, but also the ****same responsibility of the managers and the managed of network information security; it is not only the national responsibility, but also the ****same responsibility of the whole people and the whole society. At the same time, due to the transnational nature of network information security issues, when a country can not "clean up their own snow", network information security is not only a single country responsibility, but also the international community's **** the same responsibility.

Network information security is a kind of strategic security. Network information security problems are hidden, and the consequences of its triggering have a delayed nature. For example, China's information technology in the core, key areas of independent control is not yet strong, in the country's key infrastructure networks and important information systems will still be used to a certain extent in foreign software, hardware equipment, and even related supporting technical services are also borne by foreign companies, and these software and hardware equipment may be retained in the back door of the technology and hidden commands, although it will not be immediately harmful to my national security, but in the long term

It is difficult to avoid the possibility of being restrained by others in extraordinary times.

At present, the concept of network information security has been extended from the traditional technical security to information content, information activities and ways of security, from the passive "elimination of threats" to the development of national "control" and "influence" on the relevant aspects. "Influence". At the level of national strategy, some Western countries have made the information network an important battleground and platform for promoting their values and carrying out ideological infiltration and competition. For example, the United States has always attached great importance to "E-diplomacy", especially the use of Facebook, Twitter, YouTube and other platforms to convey foreign policy information. The RAND Corporation, which has a strong official background, began researching the non-traditional regime change technique known as "swarming" many years ago, i.e., targeting young people's preference for the Internet, cell phones and other new communication tools, and using text messaging, discussion forums, blogs and a large number of social networks to make young people susceptible to influence to contact and gather together, and to obey the orders of the regime change. The orders of the regime change. From domestic and international media reports, emerging online media such as Facebook and Twitter have played an important role in the recent unrest and riots in Tunisia, Egypt and other Middle Eastern and North African countries.

Network information security is a kind of positive security. First, network information technology is always evolving, and its rapid changes make any security only relative. Therefore, the national network information security can only be a positive security, only continuous scientific and technological innovation, in order to occupy the heights of information technology, any negative response to the network information security concept, bring the "temporary security" can only be the future "insecurity". Secondly, the asymmetry of network information security issues, so that any organization or individual can confront the state through the network. The cost of network criminal behavior is low, the way and means are simple and flexible, not subject to geographical and national boundaries, and even a person can create a wide-ranging network information security incident. This asymmetry makes national network information security must always be in an active defense posture, with timely warning, rapid response and recovery capabilities. Again, network information security in a certain sense embodied in the network discourse and information control, which has subverted the traditional concept of security in the concept of homeland security, and even extends beyond the scope of national sovereignty jurisdiction, both in a passive sense contains a variety of destructive and intrusive behavior of the defense, but also in the active sense covers a country's own information dissemination power and influence.
