The design of a secure product enclosure is crucial to prevent attackers from gaining access to the internal circuitry. Once the circuit board is accessible to the attacker, he or she will typically reverse-engineer the design to create a schematic and then identify possible attack vectors. Opening some products is as simple as loosening a few screws or prying open the side with a hobby knife or screwdriver (as shown in Figure 1).
