Access Control Policy Management Based on Data Classification and Hierarchy

The integrated management information system gathers all kinds of data on a unified storage, management and application platform. Establish strict data classification and hierarchy mechanism and corresponding access control methods to ensure the security of data access. This paper proposes a policy-based access control mechanism for data classification and hierarchy. It uses the attributes of the subject and object, environment variables, and related information to control the access of resources. It can describe users’ various access control requirements more flexibly and accurately, and implement access control quickly according to the changes in the operating environment to ensure the security of important data and function modules.
