Answer 2

from Wikipedia:

An information technology (IT) audit or information systems (IS) audit is an examination of the controls within an entity's Information technology infrastructure. It is the process of collecting and evaluating evidence of an organization's information systems, practices, and operations. Obtained evidence evaluation can ensure whether the organization's information systems safeguard assets, maintains data integrity, and is operating effectively and efficiently to achieve the organization's goals or objectives.

An IT audit is similar to a financial statement audit in that the study and evaluation of the basic elements of internal control are the same. However, the purpose of a financial statement audit is to determine whether an organization's financial statements and financial condition are presented fairly in accordance with generally accepted accounting principles (GAAP). Regarding Protection-of-Information-Assets, one purpose of an IT audit is to review and evaluate an organization's information system's availability, confidentiality, and integrity by answering questions such as:

Will the organization's computer systems be available for the business at all times when required? (Availability)

Will the information in the systems be disclosed only to authorized users? (Confidentiality)

Will the information provided by the system always be accurate, reliable, and timely? (Integrity).

IT audits are also known as automated data processing (ADP) audits and computer audits.
