Abstract

Techniques and systems described herein relate to monitoring executions of computer instructions on computing devices based on learning and generating a control flow directed graph. The techniques and systems include determining a learned control flow diagram for a process on a computing system and monitoring execution of the process on the computing system using the control flow diagram. An unobserved transition is determined based on the learned control flow diagram and the unobserved transition is classified as safe or unsafe based on a monitoring component analysis. An action is performed based on the safety classification and the learned control flow diagram.
