As computing device technology advances, system security has become increasingly challenging in
protecting physical system hacking. With advent of new hardware equipment and software tools, even an
unskilled person can gain access the system and instrument a setup to tap in critical buses and capture
password for login one’s account to steal sensitive data. Systems at public place, shared workspace and
lost unit are particularly vulnerable as they could fall under wrong hand. Defending physical attacks in
firmware and software is very difficult as the data can be plucked directly from hardware signals on
system board of the computing device with the right equipment.
