    摘要: A method for network isolation management is described. The method includes assigning or creating one or more isolation groups for at least one service, wherein resources of services assigned in an isolation group are shared with or without isolation; wherein an isolation group is defined for at least one resource in each layer and each domain to gather the at least one resource of the at least one service; linking an isolation profile for each of the one or more isolation groups, wherein the isolation profile comprises at least one policy to protect the at least one resource of the one or more isolation groups, and wherein the isolation profile comprises at least an isolation level to define a type of isolation; and allocating or reallocating the at least one resource to the at least one service based on the isolation profile linked to the one or more isolation groups.

    摘要: Example embodiments of the present disclosure relate to dynamic authorization. According to embodiments of the present disclosure, a solution for dynamic access control to data is proposed. On receiving data registration from a data source, a first device checks the data types to be produced by the data source and adds policies for the data or updates existing policies for the data according to its property. It also serves as access control decision point to determine consumers' access rights based on centrally managed policies. Authorization for data access is granted/denied according to local attributes/policies. In this way, it achieves a dynamic, context-aware and risk-intelligent access control to different kind of data from various data sources (i.e., service producers).

    摘要: Example embodiments of the present disclosure relate to access token revocation in security management. In an example method, in response to providing, to a second device, an access token for the second device to access a NF service from a third device, a first device stores a mapping indicating an association among the access token, the second device and the third device. In response to determining that the second device is abnormal, the first device sends, to at least one target device based on the mapping, an indication of revoking the access token. In this way, at least one target device associated with revoked access token can be informed and potential damage caused by the abnormal NF can be eliminated.

    摘要: A credential manager imports credentials for a network slice in response to deployment of the network slice. The credentials are not known to other network slices. A repository is configured to store the credentials and protect the credentials based on credential protection policies that are defined by a service profile of the network slice. The repository is implemented in the credential manager, an authentication, authorization, and accounting (AAA) server, or other location. Properties of the credentials are modified in response to a modification trigger and the credentials are withdrawn in response to a withdrawal trigger.
