What are the goals of network security work?

The goals of network security include information confidentiality, information integrity, service availability and auditability; network security means that the hardware, software and data in the network system are protected from accidental Or be damaged, altered, or leaked due to malicious reasons, the system will continue to operate reliably and normally, and network services will not be interrupted.

The goals of network security work include: 1. Information confidentiality; 2. Information integrity; 3 , Service availability; 4. Reviewability.

Related introduction:

Network security (Cyber ​​Security) refers to the protection of network system hardware, software and data in the system from damage due to accidental or malicious reasons. , changes, leaks, the system continues to operate reliably and normally, and network services are not interrupted.

On April 27, 2020, the Cyberspace Administration of China, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of National Security, the Ministry of Finance, the Ministry of Commerce, the People's Bank of China, and the National Market Supervision A total of 12 departments including the State Administration of Radio and Television, the State Administration of Radio and Television, the State Secrecy Administration, and the State Cryptozoology Administration jointly issued the "Cybersecurity Review Measures", which will be implemented on June 1, 2020.

Concept:

Network security usually refers to the security of computer networks. In fact, it can also refer to the security of computer communication networks. A computer communication network is a system that interconnects several computers with independent functions through communication equipment and transmission media, and with the support of communication software, realizes the transmission and exchange of information between computers. Computer network refers to a system that uses communication means to connect a number of independent computer systems, terminal equipment and data equipment that are relatively scattered geographically for the purpose of sharing resources, and exchanges data under the control of protocols. The fundamental purpose of computer networks is resource sharing, and communication networks are the way to realize network resource sharing. Therefore, computer networks are safe, and the corresponding computer communication networks must also be safe, and should be able to realize information exchange and resource sharing for network users. In the following, network security refers to both computer network security and computer communication network security.

The basic meaning of safety: objectively there is no threat and subjectively there is no fear. That is, the object does not worry about its normal state being affected. Network security can be defined as: a network system is free from any threats and infringements and can normally realize resource sharing functions. In order for the network to realize the resource sharing function normally, we must first ensure that the network hardware and software can operate normally, and then ensure the security of data information exchange. As can be seen from the previous two sections, the abuse of resource sharing has led to network security problems. Therefore, the technical approach to network security is to implement restricted sharing.
