Information security refers to the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction to provide:
integrity
Prevent inappropriate information modification or destruction, and ensure non-repudiation and authenticity of information.
Confidentiality
Retain authorized restrictions on access and disclosure, including means to protect personal privacy and proprietary information.
availability
Ensure that access and use of information is timely and reliable.
Sometimes when referring to the "global security framework", in addition to the above three points, the three security structure factors of authenticity, auditing and identity authentication are also put forward separately.
