Securing Microservices Utilizing a Proactive Condition Map

A computer system for validating microservice calls, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• determine, using a validation proxy of the computer system, whether a microservice call to a microservice hosted by the computer system is valid based on a policy in a proactive condition map of the validation proxy that matches the microservice call;
• block, using the validation proxy, the microservice call to the microservice in responsive to determining that the microservice call is invalid based on the policy in the proactive condition map that matches the microservice call;
• determine, using the validation proxy, whether the microservice call needs to be redirected to another microservice based on the policy;
• and
• redirect, using the validation proxy, the microservice call to the other microservice with a callback to the microservice in response to determining that the microservice call does need to be redirected to another microservice based on the policy.

A computer program product for validating microservice calls, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method of:

• determining, by the computer, using a validation proxy of the computer, whether a microservice call to a microservice hosted by the computer is valid based on a policy in a proactive condition map of the validation proxy that matches the microservice call;
• responsive to the computer determining that the microservice call is invalid based on the policy in the proactive condition map that matches the microservice call, blocking, the computer, using the validation proxy, the microservice call to the microservice;
• determining, by the computer, using the validation proxy, whether the microservice call needs to be redirected to another microservice based on the policy;
• and
• responsive to the computer determining that the microservice call does need to be redirected to another microservice based on the policy, redirecting, by the computer, using the validation proxy, the microservice call to the other microservice with a callback to the microservice.
