Abstract: Embodiments of this application provide a time synchronization method, a service board, and a network device. After clock board times between service boards are synchronized, the service board obtains a CPU time and the clock board time of the service board according to a preset periodicity, and makes a record; when performing CPU time synchronization between the service boards, the service board obtains a current CPU time of the service board, and calculates a synchronization time of the CPU based on the current CPU time, and a last recorded CPU time and clock board time; and adjusts the CPU time of the service board to the synchronization time. After the clock board times between the service boards that need to implement CPU high-precision time synchronization are synchronized by using a high-precision time synchronization protocol, the CPU time of each service board is adjusted to a corresponding synchronization time.

Abstract: Embodiments of the present invention disclose a cyber security management system, method, and apparatus. The system includes UE, an AN, a network function selection module, and at least two authentication modules. The UE is configured to send a first service request to the network function selection module, where the first service request carries authentication protocol information. The network function selection module is configured to: select a target authentication module based on the authentication protocol information, and send a second service request to the target authentication module. The target authentication module is configured to perform mutual authentication with the UE. The target authentication module is further configured to: determine a first security configuration according to a specified security policy, and send the first security configuration to the AN.
