Auditing Information Systems [Hardcover]

This is a readable and current introduction to information systems auditing from a qualified and experienced IS auditor.

The book consists of three parts. Part One introduces core information systems concepts and is aimed at readers without much background in IS; Part Two introduces IS audit itself, and Part Three discusses some additional concepts and issues, such as control self-assessment and the human factor. Case studies are extensively used throughout the book to illustrate concepts, approaches and procedures discussed in the text.

While the author is writing from a US perspective and has US work experience, references to British, Canadian, and Australian standards, qualifications and practices are included. One of the good characteristics of this book is its readability and easy flow of information, unlike many other works in this field.

I haven't given this book five stars because in my opinion its coverage of "information systems" is somewhat limited compared with the coverage of "auditing". So if you are looking for a detailed technical volume on information systems auditing, look elsewhere; this book gives a well-rounded non-technical introduction to information systems auditing and does it well.

5 years ago I was asked to help internal auditors with a helpful audit program, so I decided to do some research and purchased this book over the internet.
I am not a professional reviewer, I lack the tactfulness to state my feelings about a book without offending at least the author. Well, here it is in a single statement - do not buy this book! -
It is too expensive for a new auditor and too basic for a seasoned auditor who should know about most of the points made in the book.
First chapter the author felt the urge to explain computers and used the term CPU, a box containing hardware. The original 1946 EDVAC may have been called a CPU. The author continues ..."there are thousands of them" what a joke. and if you keep reading how he explains memory you will start laughing uncontrollably " the more memory you have the more applications you can run" .
There are some good points made and planty of case studies but I ended up using articles I found on the internet for a great audit program based on BS7799.
I would recommend, reading books about ISO 2700x for creating great audits.

An organised and easy to read book.
Champlain has written the book such that it meets the needs of 2 classes of readers; an auditor who has no experience in auditing an information system and someone who is familiar with information systems and is interested to know and understand the auditing process in their areas.
The book is organised into 3 sections: Core Concepts, Standard information system audit approach and Contemporary information systems auditing concept.

In Core Concepts, Champlain introduced the auditor to the basic architecture of information systems and how information systems are generally organised and structured.

In Standard information system audit approach, Champlain lead the auditor through the common areas that an auditor should cover to assess the adequacy of the information systems' controls to prevent unauthorised access and accidental or intentional destruction of programs. Champlain provides explanation on why these areas should be evaluated and helps readers working with information systems understand the rationale for the audit approach. Champlain shared with the readers numerous examples on control weaknesses over physical and logical accesses. However, I found the section on assessing the financial stability of vendor organisation could be further improved.

In Contemporary Information Systems auditing concept, Champlain introduced the reader to the control self-assessment and the 6 internal audit frameworks; COSO, CoCo, Cobit, SAC, eSAC and SASs 55/78/94. The concept and various approaches for Control Self Assessment for IS was introduced. In the chapter on cryptography, Champlain highlighted that encryption, hashing and digital signatures support a secure electronic message and are essential for the electronic commerce transactions.

Champlain provided a brief introduction to computer forensics and other contemporary computer challenges such as computer assisted audit techniques, computer viruses, software piracy and internet security. As part of professional enhancement, Champlain provided the reader with a list of available professional associations that provide and confer professional accreditations. In the final chapter, Champlain shared with the readers a methodology for Information System Project Management.

As an introductory to information system audit, this book earns high marks. However, if you are experienced information system auditors, this book is useful only as a refresher on some of the common information system controls.
