The power path is the electrical route that carries operating voltage from a source to a device or component. It includes traces, connectors, regulators, capacitors, and other parts that condition and deliver power. If any part of that route fails, the device may not boot, initialize, or communicate, even when the memory or logic chips are intact.
In cyber security, power-path faults matter because they can look like malware damage, wiped storage, or a bricked device. On removable media, embedded gear, and field equipment, a shorted capacitor or bad regulator can prevent access to logs, firmware, or evidence. Attackers may also exploit weak power design through tampering, while defenders and repair teams use power-path checks to separate electrical failure from true data loss and avoid unnecessary replacement or destructive recovery attempts.
