Data expansion:

Network security means that the hardware and software of the network system and the data in the system are protected from being destroyed, changed or leaked due to accidents or malicious reasons, and the system runs continuously and reliably without interrupting the network service.

Network security usually refers to the security of computer networks, and in fact it can also refer to the security of computer communication networks.

Computer communication network is a system that connects multiple computers with independent functions through communication equipment and transmission media, and realizes information transmission and exchange between computers with the support of communication software.

Computer network refers to a system that connects several independent computer systems, terminal equipment and data equipment scattered in the region by means of communication under the control of the protocol for data exchange.

The fundamental purpose of computer network is to enjoy resources, and communication network is the way to realize network resources. Therefore, the computer network is secure, and the corresponding computer communication network must also be secure. It should be able to exchange information and enjoy resources for network users. Hereinafter, network security refers to both computer network security and computer communication network security.

The basic meaning of security:

There is no threat objectively, and there is no fear subjectively. That is, the subject is not worried that his normal state will be affected. Network security can be defined as: a network system is free from any threats and violations, and can normally realize the function of resource sharing.

In order to make the network realize the function of resource sharing normally, we must first ensure the normal operation of network hardware and software, and then ensure the security of data information exchange. As can be seen from the previous two sections, the abuse of resources has led to network security problems. Therefore, the technical way of network security is to implement limited enjoyment.
