1. What is network security?

Network security refers to the ability to take necessary measures to prevent attacks, intrusions, interference, destruction, illegal use and accidents on the network, make the network in a stable and reliable state, and ensure the integrity, confidentiality and availability of network data.

2. Why is network security important?

Nowadays, network security and informatization have an impact on many fields of a country, and network security has become an important part of national security. Without network security, there will be no national security, no stable economic and social operation, and it will be difficult to protect the interests of the broad masses of the people.

From a global perspective, the threats and risks of network security have become increasingly prominent, and have penetrated into political, economic, cultural, social, ecological, national defense and other fields. Network security has become one of the most complex, realistic and severe non-traditional security problems facing our country.

3. How to establish a correct concept of network security?

To correctly establish the concept of network security, we must clearly understand the main characteristics of network security:

First, network security is holistic, not fragmented. In the information age, network security is closely related to national security and many other aspects of security.

Second, network security is dynamic rather than static. The network has become highly interrelated and interdependent, and the threat sources and attack methods of network security are constantly changing, so it is necessary to establish a dynamic and comprehensive protection concept.

Third, network security is open rather than closed. Only based on an open environment, strengthen foreign exchanges, cooperation, interaction and games, and absorb advanced technologies, will the level of network security be continuously improved.

Fourth, network security is relative rather than absolute. There is no absolute security. We should ensure security based on the basic national conditions and avoid pursuing absolute security at all costs.

Fifth, network security is universal rather than isolated. Network security is for people, and network security depends on people. Maintaining network security is the common responsibility of the whole society, which requires the joint participation of the government, enterprises, social organizations and the majority of netizens to build a network security defense line.
