“While the sheer enormity of these systems may seem daunting, there are many opportunities within each sector to help improve the security and resilience of our infrastructure. One such opportunity is Intelligent Traffic Systems (ITS).”
physical access to traffic infrastructure exposes agencies to both physical and cyber-related attacks. With Connected and Autono- mous Vehicles (CAV), Vehicle-to-Infrastructure (V2I) connectiv- ity, and more IoT connected devices than ever before, legal and liability issues are a reality for agencies operating these assets.
Entry into any traffic cabinet must be authorized, managed and monitored in real-time. Thankfully, this can be accomplished with robust solutions that are available for both online and offline access control.
USING A LAYERED APPROACH
TO ADDRESS PHYSICAL AND CYBER SECURITY
ITS cabinets are an excellent example of the interdependency be- tween physical security and cybersecurity. A vulnerability in the
physical security of these cabinets creates a major risk for the cy- bersecurity of the systems and networks accessible through the connections housed within the cabinets. We are able to mitigate the cybersecurity risk by proactively addressing physical security.
This concept applies beyond transportation to the unmanned infrastructure in all of the sectors identified by DHS as critical. We see cabinets and enclosures across the country in rural areas or along highways, in fields, following power transmission lines or along railways that now provide the connectivity from “Informa- tion Technology” in the office to “Operational Technology” in the field. This is the very fabric that connects our infrastructure.
So, this layered approach can be applied across almost any applica- tion, and will become increasingly important as the need to protect the cybersecurity of our nation’s critical infrastructure continues to grow. Highlighted by the recent ransomware attack against the Colo- nial Pipeline and President Biden’s executive order to improve cyber- security, we are facing constant threats to our economic and physical security. It is our responsibility as security profes-
sionals to bring knowledge, awareness, and action
to protect against these threats.
