Research on IT Asset Data Access Rights Authentication for IoT Terminals in Cloud Environment

Influenced by the unrefined management of permissions and security risks, IT asset data access faces more and more security threats. Therefore, this paper proposes a research on IT asset data access rights authentication for IOT terminals in cloud environment. The access control of personnel at all levels to the functional pages is achieved through role division; the user's access to files, database tables and other objects is controlled based on the security policy; the coverage of access control includes the subject, object and operations between them related to resource access; the authorised subject configures the access control policy, and the access privileges of the default account are strictly restricted. The experimental results show that the IT asset data access permission authentication of IoT terminal in cloud environment can effectively solve the security problems such as single-point trust failure of trusted third party and difficulty in satisfying the minimum authorisation principle with multi-domain heterogeneity in cross-domain authentication of IoT terminal.
