This is not what the book says at all. At page 233, under PANs and WANs, the book states that "Whenever a slaved device is called on to make a defense test, it uses either its own or its master’s rating for each rating in the test."
Strictly by RAW you can use any of the deck's attributes in defensive rolls, including Sleaze against Matrix Perception and Trace Icon (Even Attack can be used in defensive rolls against Jack Out if you somehow manage to link-lock your opponent).
