Physical access to the assets is one of the major threats at the edge. Defense mechanisms like video surveillance, tamper seals, or even in-person security guards are often not an option for cost and practical reasons. Locking devices in a cabinet is a form of protection, but since these are unmanned in many locations, it gives malicious actors all the time they need to plan and execute a breach. A keylock gives limited protection as the theft of the whole cabinet in many cases is the biggest worry in these scenarios. Alternative methods are required to defend against physical access.
