I am a Senior in mechanical engineering at the New York City College of Technology in Brooklyn New York. Over the past three years, I have worked with my school and several others both inside and outside of the US in order to research and learn more about Additive Manufacturing and how it is incorporated with the engineering supply chain and design process. This includes working with NYU over the summer as part of their NSF IRES summer research program with students from India to learn how cyber security plays a role in AM and how machine learning can be used to combat cyber/physical attacks,

ABSTRACT

In the additive manufacturing (AM) supply chain, there are numerous factors that may allow malicious third parties to negatively influence the specific outcomes of a given product. These factors are known as threat vectors, and commonly include avenues for counterfeiting, information leakage, and sabotage. To determine the specific risks within a given production line, product designers should perform risk analyses to study the likelihood of various attacks. These can be visualized as heat maps, which then allow for designers to address possible attackers and determine the likelihood and vector they may begin navigating. To that effect, a case study was examined in order to address possible sabotage attacks. Attackers seeking to sabotage may introduce malicious files into groups of benign files. For AM one such case where this applies is with G-Code files, and through the application of machine learning the malicious files can be detected through feature recognition in the code seeing how the altered ones deviate from the acceptable ones thus finding the fault(s) in the pile.
