You are a technician working for the intelligence agency of Amoria. Your employer is extremely curious about what goes on in a particular ministry of Bumaria. This ministry has ordered networked computers from an Amorian supplier and you will be given access to the shipment before it reaches the customer. What modifications could you perform on the hardware (and system software) to help with later break-in attempts, knowing that the Bumarian government only uses software from sources over which you have no control?
