National Academies: “Since 2009, when NCHRP’s last Security 101 report was released, there have been significant advances in transportation security approaches, including new strategies, programs, and ways of doing business that have increased the security of transportation systems as well as ensured their resiliency. Hazards and threats to the system have also continued to evolve since 2009. While the incidence of large-scale terrorist attacks has remained small, transportation agencies are at increasingly greater risk from system-disrupting events due to natural causes, unintentional human intervention, and intentional criminal acts, such as active-shooter incidents. Cyber risks also are increasing, and can impact not only data, but the control systems – like tunnel-ventilation systems – operated by transportation agencies.
