According to an aspect of some embodiments of the present invention there is provided a method for verifying correctness of application configuration of an application, comprising: for each of baseline and changed source codes of an application analyzing a graph representation of an execution flow of a plurality of application functionalities performed by execution of the respective source code to identify a plurality of functional dependencies between source code segments of the baseline source code and a plurality of functional dependencies between source code segments of the changed source code, wherein each of the functional dependencies is at least one of data dependency and control dependency, identifying a configuration discrepancy according to a match between functional dependencies of the changed source code when compared to the baseline source code, and producing a notification when the configuration discrepancy is found and is not permitted by the configuration.
