1. A computer-implemented method comprising:
generating a model of a device under test, the model comprising a data path similar to the device under test and an attribute network;
detecting an introduction of protected data into the model;
marking the protected data with an attribute to track a flow of the protected data along the data path within the device under test in real-time;
performing security mitigation process based on detecting an exposure of the protected data;
detecting, upon completion of the security mitigation process, an end point of the marked protected data along the data path; and
issuing, in response to the end point being indicative of a vulnerability, an alert.
