If embedded systems are easy to access physically, attackers could destroy or damage them (e.g. using mechanical force, short circuits, or excess voltage). They could also access the electronic components (e.g. IC pins or contacts) and thus record electrical signals unnoticed with corresponding measuring and analysis tools, or feed in signals themselves. When attackers gain possession of an embedded system, they can use physical procedures to read and manipulate data or access data that has not been securely deleted. This may result in the confidentiality, integrity, or availability of the information stored on the embedded system being compromised.
