The objectives of the paper are to present the basic principles governing the internal audit
mission as well as the code of conduct that must be observed in exercising such a mission, because
the completion of a professional audit mission implies precisely the compliance with the two category
of elements. Consequently, this paper is meant to be added to the practice specific to this field as
support in exercising the internal audit according to the market requirements. For this purpose, we
analysed the above-mentioned elements, presenting brief examples in support of the importance of
the approached topics. Thus, from the practical point of view, we can notice the mechanisms used to
apply these principles and how the compliance with the audit specific audit conduct lead to a more
efficient activity. For these reasons, we can say that the paper is an element of interest both for the
academic field (as a starting point for the support of practical approaches) and also for the future
researches in order to improve the specific audit activity
