A machine implemented method includes storing a first data representing a prior exception to a first trust failure (e.g., expired certificate). The prior exception may be stored as part of establishing a first communication with a data processing system (e.g., a handheld device). The first communication may not be trustworthy. The method may determine, as part of establishing a second communication with the data processing system, that a second trust failure has occurred. The second trust failure (e.g., revoked certificate) indicates that the second communication may not be trustworthy. The method may determine whether the prior exception applies to the second trust failure. If the prior exception does not apply, the data processing system determines, automatically, whether to create a new exception for the second trust failure.
