Abstract

The embodiment of the invention provides a strategy conflict processing method and device based on a complex network. The method comprises the following steps: in response to a primary access request for a target system, determining at least two access control policies in an access control policy set; if the determined access control policies conflict, determining nodes corresponding to at least two access control policies in the main network, and acquiring importance information corresponding to the determined nodes; determining an executed access control policy from at least two access control policies based on the acquired importance information; wherein nodes in the main body network are main bodies of access control policies in the access control policy set; the importance information of the nodes in the subject network reflects the importance degree of the subject of the access control strategy to the target system through the object of the access control strategy. According to the embodiment of the invention, strategy selection can be carried out scientifically and reasonably when access control strategy conflicts are solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method and device for handling policy conflict based on a complex network. Background technique [0002] With the development of computer network technology, network security has become an important issue in the development of computer networks. Among the many types of cybersecurity, insider risk accounts for the vast majority. Internal risks are mainly caused by illegal and unauthorized use of the system by legitimate users. At present, the access control mechanism is mainly used to limit user access rights to avoid illegal and unauthorized operations. Common access control models include access control matrix, discretionary access control, mandatory access control, role-based access control, attribute-based access control, etc. All access control models need to configure a large number of access control policies. There is a policy conflict. For example, pol...
