Abstract: According to the work on."A Guideline on Computer Information System Security Protection Classifying (abbrcviated as TheGuideline below)" and based on the design framework of information security, this paper introduces main features of each security protectiondivision and class described in the Guideline. The purpose of the Guideline is to support the establishment of laws on security of computerinformation systems. It also provides functional framework for research and development of informahon security products and technicaltutorials on the construction and management of security systems.
