Methods and systems for evaluating microservice system level activities including system calls and commands, and generating security policies for microservices are disclosed. A microservice agent, operating on a microservice host, can collect system level activity data corresponding to a plurality of microservices operating on the microservice host. The microservice agent can transmit the system level activity data to a microservice evaluator that can use the system level activity data to train machine learning models to identify normal and abnormal microservice system level activities. The normal and abnormal system level activities can be used to generate security policies that can be applied to the microservices. Microservices that perform abnormal system level activities or system level activities that violate security policies can be paused or terminated.

Disclosed are methods for authorizing a transaction, including receiving a policy message, the policy message including a policy ruleset for determining whether a transaction is authorized and biometric parameters for a machine learning algorithm for authenticating an identity of a user involved in a transaction, receiving biometric measurement data associated with a biometric measurement of a user involved in the transaction, calculating an authentication score based on the biometric measurement data using the machine learning algorithm, wherein the authentication score includes an indication of whether an identity of the user is authenticated based on the biometric measurement data, determining whether the transaction satisfies the policy ruleset for determining authorization of the transaction, and transmitting a decision message, wherein the decision message includes an indication of whether the transaction satisfies the policy ruleset. Systems and computer program products are also disclosed.
