In order to understand the inner insinuation of this new area, this
paper conducts a study to investigate the implications of IT auditing,
cloud computing, and cloud computing auditing. After examining the
development horizon, this paper lays down a number of challenges
that face the field of cloud computing, including technological complexity,
security risk, its weaknesses and immaturity, lack of cloud computing
audit standards, and contractual issue such as SLA. A future
development issue could be knowledge worker’s training and knowledge
management system’s construction.
