The aim of these notes is to give potential computer auditors an overview of the main activities of computer audit and the role of the computer auditor. They have been written to assist candidates who are planning to attend an interview for a position in computer audit but have a limited knowledge of the subject. For those from either an audit, business or information technology (IT) background seeking a move into computer audit, these notes will provide useful background reading. Whilst any organisation that has agreed to interview a candidate who has limited experience of computer auditing will judge them accordingly, there is substantial scope for candidates to improve their chances by.
