Brian Douglas ‘25 presented a poster on his independent research at the Symposium on Usable Privacy and Security (SOUPS) 2025. In the work, titled “Light Security: Discovering Vulnerabilities in Theatrical Lighting Control Systems and Assessing Their Prevalence,” Brian characterized security vulnerabilities in the networked lighting control systems used by theaters, concert halls, and other entertainment venues. Combining experiments in theaters at two educational institutions with a survey of hundreds of lighting professionals, he found that 72% of surveyed venues are vulnerable, with the risk rising to 98% in large venues. Brian conducted the research under the guidance of Prof. Gember-Jacobson. The poster is available here.
