METHOD, DEVICE, AND SYSTEM FOR INCREASING CROSS-NETWORK ACCESS SECURITY

摘要

Embodiments of the present application provide a method, device, and system for increasing cross-network access security. In the embodiments of the present application, in a scenario in which a UE accesses a second network via a first network, a security event (e.g., an authentication condition) of the UE is recorded at the second network, a decision result is determined for a subsequent behavior of the UE, and the decision result is notified of the first network so that the first network performs security processing on the subsequent behavior of the UE for the second network, thereby realizing security interaction of the first network and the second network. A malicious UE is managed at the proximal of the first network, thereby reducing communications loads of the first network and the second network and also guaranteeing the network security of the second network.
