Method and System for Providing Edge Service, and Computing Device

A method for providing an edge service implemented by a security controller, wherein the method comprises:

• receiving link access requests from a plurality of endpoint computing devices.;
• sending, to each endpoint computing device of the endpoint computing devices, first edge link information comprising a first address of a first security agent;
• receiving, from the first security agent, link abnormality information comprising a second address of an abnormal endpoint computing device in the endpoint computing devices;
• and
• generating, based on the link abnormality information, second edge link information comprising a third address of a second security agent.

A computing device comprising:

• a memory configured to store computer executable instructions;
• and
• a processor coupled to the memory, wherein the computer executable instructions that when executed by the processor cause the computing device to be configured to:
• receive link access requests from a plurality of endpoint computing devices;
• send, to each endpoint computing devices, first edge link information comprising a first address of a first security agent;
• receive, from the first security agent, link abnormality information comprising a second address of an abnormal endpoint computing device in the endpoint computing devices;
• and
• generate, based on the link abnormality information, second edge link information comprising a third address of a second security agent.
