Five characteristics of network security

The five attributes of network security include confidentiality, integrity, availability, controllability and non-repudiation, which are applicable to a wide range of fields such as education, entertainment, medical care, transportation, national security, power supply and communication of national information infrastructure.

1, confidential

The feature that information will not be disclosed or used by unauthorized users, entities or processes. Confidentiality means that information in the network is not obtained and used by unauthorized entities (including users and processes).

This information includes not only state secrets, but also business secrets and work secrets of enterprises and social groups, as well as personal information.

Step 2 be complete

The characteristics of data cannot be changed without authorization. In other words, information remains unchanged during storage or transmission, and is not destroyed or lost.

Data integrity refers to ensuring that the data and information on the computer system are in an intact state, that is, the data will not be changed or lost due to intentional or unintentional events.

3. Effectiveness

Availability refers to the expected ability to use information or resources, that is, the characteristics of authorized entities or users to access and use information as required.

4, controllability

Controllability refers to people's ability to control the transmission path, scope and content of information, that is, bad content is not allowed to spread through public networks, so that information is under the effective control of legitimate users.

5. Non-repudiation

Undeniability is also called undeniability. In the process of information exchange, we are convinced of the true identity of the participants, that is, all participants can't deny and deny the completed operations and commitments.
