Introduction
With a view to cooperating with the implementation of Cybersecurity Law of the People's Republic of China and adapting to the proceeding of classified protection of cybersecurity under new technologies and applications such as cloud computing, mobile communication, internet of things, industrial control and big data, GB/T 22239-2008 shall be revised; the revision idea and method are to adjust the contents of GB/T 22239-2008, propose general security requirements in allusion to general security protection requirements and put forward special security requirements in allusion to individualized security protection requirements of new technologies and applications such as cloud computing, mobile communication, internet of things, industrial control and big data in order to form new standard of baseline for classified protection of cybersecurity.
This standard is one of the series standards related to classified protection of cybersecurity.
Standards in relation to this one include:
——GB/T 25058 Information security technology - Implementation guide for classified protection of information system;
——GB/T 22240 Information security technology - Classification guide for classified protection of information system security;
——GB/T 25070 Information security technology - Technical requirements of security design for classified protection of cybersecurity;
——GB/T 28448 Information security technology - Evaluation requirement for classified protection of cybersecurity;
——GB/T 28449 Information security technology - Testing and evaluation process guide for classified protection of cybersecurity.
In the text of this standard, those in bold represent requirements added or strengthened in higher level.
Information security technology - Baseline for classified protection of cybersecurity
1 Scope
This standard specifies the general security requirements and special security requirements for the targets of classified security from Level 1 to Level 4 under the classified protection of cybersecurity.
It applies to guide the security construction and supervisory management for classified non-secret-involved targets.
Note: The Level 5 targets of classified security are very important objects for supervision and management. There are special management mode and security requirements proposed for them, which are not expatiated herein.
