The reported research results address challenges in the electromagnetic defence of critical infrastructure and mission-critical equipment, including potential vulnerability to electromagnetic interference (EMI) and possible loss of mission-critical data, especially in mobile, field-deployable systems that are less protected than static, permanent sites. To achieve this, we develop an innovative toolset of technologies that are lightweight, easy to move, and fast to deploy while still being highly efficient at protecting our data and systems both passively and actively. This includes the development of novel advanced materials shields, electronics and AI cybersecurity technologies. Thus, the goal of the research is to develop a prototype set of tools that provide enhanced electromagnetic protection and cybersecurity in the field by researching and developing innovative lightweight and field- deployable shielding solutions in tandem with AI-based monitoring solutions for electromagnetic and cyber domains that can allow identification of potentially dangerous situations where shielding is not sufficient to prevent data theft or other types of electronic warfare and data or equipment loss is imminent, thus as a last resort can initiate the destruction of secure data drives before the data falls into the wrong hands closing the complete data protection loop strategy: shielding, monitoring, and prevention/data destruction.
