In cybersecurity, 'trestle' does not refer to a digital concept but rather to its traditional meaning: a framework, typically made of wood or steel, used to support a bridge or elevated structure, especially on railroads. The term may appear in discussions about physical security or infrastructure protection, where the integrity of trestles is crucial to prevent sabotage or unauthorized access. Understanding the role of trestles in physical infrastructure helps cybersecurity professionals assess risks related to critical assets that could impact digital systems if disrupted.
