Information security classified protection is a basic system
of China’s information security
protection. Conducting information security classified protection in colleges
and universities is not only a key content in strengthening national information
security work, but also an effective measure to improve the information security
level of university networks. The paper first summarizes common information
subsystems in China’s universities
and colleges, describes the functions of these subsystems and offers the recommended
classified protection levels for these subsystems. Then, this paper divides
an university information system into various modules based on security domain
according to the security strategy of “all
Grade II systems forming one security domain and each Grade III forming one
security domain” and gives the
access control methods for security domain boundaries. Finally, according to
the requirements on Grade II systems by China’s
national standards concerning classified protection, this paper analyzes the
contents and objectives of security construction for Grade II security domains
from five aspects, thus offering a reference for universities to conduct classified
protection based information security construction.
