How Can I Ensure the Security of Backend Services Invoked by APIC?

You can ensure the security of backend services invoked by APIC by using the following methods:

• Bind signature keys to APIs. After a signature key is bound to an API, APIC adds signature information to each request sent to the backend service. The backend service calculates the signature information in each request and checks whether the signature information is consistent with that on APIC.
• Encrypt requests using HTTPS. Before using this method, ensure that the required SSL certificates are available.
