Abstract: Various examples of embodiments described herein relate to methods and apparatuses for mitigation against access token theft attack in direct and indirect communications in SBA. One such example of an embodiment relates to a method that includes obtaining a first access token request from a network function service consumer, NFc, the first access token request comprising an authentication code of the NFc; authenticate the network function consumer, NFc, based on a check whether the authentication code is signed by the NFc; sending a second access token request to a network authorization entity or function, wherein the second access token request comprises the authentication code of the NFc and the second access token request further comprises a public key of the NFc or a hash of the public key of the NFc; based thereon, receiving an access token from the network authorization entity or function, wherein the access token comprises the public key of the NFc or a hash of the public key of the NFc; and sending a service request to a network function service provider, NFp, wherein the service request comprises the access token and the authentication code of the NFc.

Abstract: Techniques for dynamic security management in a communications network are disclosed. For example, a method comprises obtaining, at a network entity in a communication network, security information from one or more other network entities in the communication network. In response to at least a portion of the obtained security information, the method enables, by the network entity, dynamic enforcement within a user plane of the communication network of one or more security policies in accordance with one or more quality-of-service policies to manage one or more behaviors of user equipment.
