    Information technology (IT) serves a critical role in state operations. State agencies and higher education institutions are increasingly reliant on the automated processing of information. It is important that the IT applications that process information have controls to ensure and protect the accuracy, integrity, reliability, and confidentiality of the State’s information.

     Due to the increased reliance on IT applications, a significant portion of the audits the State Auditor’s Office (SAO) performs include an IT component. Auditors select IT controls for testing during an audit based on a risk assessment. The risk assessment considers, among other factors, the objectives and scope of the audit. Therefore, the SAO does not test all IT controls in every audit, with the high-risk and high-impact IT controls being tested more frequently. In addition, to minimize security risks, the SAO does not publicly report sensitive IT audit issues, in accordance with the Texas Government Code, Section 552.139.

   Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it was volatile in that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of nonvolatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world’s first commercially available general-purpose electronic computer.
