Cyber security management system, method, and apparatus

A cyber security management system, wherein the management system is configured to implement security management of a network comprising at least two network slices, and the cyber security management system comprises user equipment (UE), an access network (AN), a network function selection module, and at least two authentication modules, wherein

• the UE is configured to send a first service request to the network function selection module, wherein the first service request carries authentication protocol information;
• the network function selection module is configured to:
• select a target authentication module from the at least two authentication modules based on the authentication protocol information, and send a second service request to the target authentication module, wherein
• the target authentication module is configured to:
• receive the second service request, and perform mutual authentication with the UE;
• and
• the target authentication module is further configured to:
• determine a first security configuration according to a specified security policy of a specified network slice to which the UE is to be attached, and send a second service request response to the AN, wherein the second service request response carries the first security configuration;
• and
• the AN is configured to:
• determine a second security configuration based on the first security configuration or the specified security policy, and send a first service request response to the UE, wherein the first service request response carries the second security configuration.
