A system and method for securing execution environments by quarantining software containers. A method includes: determining, based on configuration data for an application stored in the application software container, at least one intended behavior of the application when executed by the application software container; monitoring execution of the application software container in a first execution environment, wherein the monitoring further comprises comparing the execution of the application software container to the at least one intended behavior; detecting an unauthorized action by the application software container when the execution of the application software container is anomalous as compared to the at least one intended behavior; and quarantining the application software container by migrating the application software container from the first execution environment to a second execution environment when the unauthorized action is detected.
