Name a physical security tactic against unauthorized photography or filming.

Implementing policies against electronic device usage in sensitive areas serves as an effective physical security tactic against unauthorized photography or filming because it directly limits the ability of individuals to capture images or video within those locations. By prohibiting devices that can record, such as smartphones and cameras, organizations can significantly reduce the risk of sensitive information being photographed or filmed. This approach not only helps protect intellectual property and confidential information but also fosters an environment where employees are made aware of the importance of maintaining security standards. The presence of such policies can deter potential unauthorized actions, ensuring that the organization's sensitive areas remain secure from visual threats.
