I:integrity integrity

A:availability availability

1. Network security

It means that the hardware and software of the network system and the data in the system are protected from being damaged, changed or leaked because of accidental or malicious reasons, the system runs continuously and reliably, and the network service is not interrupted. In essence, network security is the information security on the network. In a broad sense, all related technologies and theories related to the confidentiality, integrity, availability, authenticity and controllability of information on the network are the research fields of network security. Network security is a comprehensive discipline involving computer science, network technology, communication technology, cryptographic technology, information security technology, applied mathematics, number theory, information theory and so on.

2. Three basic attributes of network security.

(1) confidentiality (confidentiality). Confidentiality means to ensure that information and information systems will not be obtained and used by unauthorized persons, and the main preventive measure is cryptographic technology.

(2) Integrity. Integrity means that the information is true and credible, the publisher is not impersonated, the source is not forged, and the content is not tampered with. The main preventive measures are verification and authentication technology.

(3) availability. Usability means to ensure that the information and information system can be used normally by authorized personnel. the main preventive measure is to ensure that the information and information system is in a reliable running state.
