History Of Information Technology Auditing
Information Technology Auditing (IT auditing) began as Electronic Data Process (EDP) Auditing and developed largely as a result of the rise in technology in accounting systems, the need for IT control, and the impact of computers on the ability to perform attestation services. The last few years have been an exciting time in the world of IT auditing as a result of the accounting scandals and increased regulation. IT auditing has had a relatively short yet rich history when compared to auditing as a whole and remains an ever changing field.
The introduction of computer technology into accounting systems changed the way data was stored, retrieved and controlled. It is believed that the first use of a computerized accounting system was at General Electric in 1954. During the time period of 1954 to the mid-1960s, the auditing profession was still auditing around the computer. At this time only mainframe computers were used and few people had the skills and abilities to program computers. This began to change in the mid-1960s with the introduction of new, smaller and less expensive machines. This increased the use of computers in businesses and with it came the need for auditors to become familiar with EDP concepts in business. Along with the increase in computer use, came the rise of different types of accounting systems. The industry soon realized that they needed to develop their own software and the first of the generalized audit software (GAS) was developed. In 1968, the American Institute of Certified Public Accountants (AICPA) had the Big Eight (now the Big Four) accounting firms participate in the development of EDP auditing. The result of this was the release of Auditing & EDP. The book included how to document EDP audits and examples of how to process internal control reviews.
Around this time EDP auditors formed the Electronic Data Processing Auditors Association (EDPAA). The goal of the association was to produce guidelines, procedures and standards for EDP audits. In 1977, the first edition of Control Objectives was published. This publication is now known as Control Objectives for Information and related Technology (CobiT). CobiT is the set of generally accepted IT control objectives for IT auditors. In 1994, EDPAA changed its name to Information Systems Audit and Control Association (ISACA). The period from the late 1960s through today has seen rapid changes in technology from the microcomputer and networking to the internet and with these changes came some major events that change IT auditing forever.
The formation and rise in popularity of the Internet and E-commerce have had significant influences on the growth of IT audit. The Internet influences the lives of most of the world and is a place of increased business, entertainment and crime. IT auditing helps organizations and individuals on the Internet find security while helping commerce and communications to flourish.

Famous quotes containing the words history of, history, information and/or technology:
“The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.”
—Shoshana Zuboff (b. 1951)
“History, as an entirety, could only exist in the eyes of an observer outside it and outside the world. History only exists, in the final analysis, for God.”
—Albert Camus (1913–1960)
“But while ignorance can make you insensitive, familiarity can also numb. Entering the second half-century of an information age, our cumulative knowledge has changed the level of what appalls, what stuns, what shocks.”
—Anna Quindlen (b. 1952)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
