The 1990s takes us into the third age of computer auditing - the age of mature theory, recognized best practice and distinctive professional qualifications.
The third edition of "Computer Auditing" which incorporates an extensive rewrite of many sections, a large amount of new material and a major change in presentation - reflects the maturity of the state of the art.
The book is primarily addressed to the auditor who is not a technical specialist - but who, being an auditor, needs to be a computer auditor.
However, the text addresses the relevant technical issues to the necessary extent.
No auditor, being a computer auditor, can avoid them, or should wish to do so.
We can at last say that all auditors are indeed computer auditors - though some do still need to be more technically specialized than others.
This third edition reflects the increasing pace of implementation of information technology.
New material covers such subjects as: trends in IT and their impact on auditors; audit of forward planning; developments in networks, electronic data interchange and multi-user systems; automated auditing procedures; use of packages (either on their own or in conjunction with systems developed in-house); variety in methods of developing systems; user developing and implementing their own systems with limited (if any) recourse to technical specialists; legal developments.
We have also sought to include more material in the form of checklists and questionnaires.
We believe that audit is, above all, a set of practical tasks rather than theoretical exercises.
