Audit: A systematic, independent, and documented process for obtaining and evaluating objectively verifiable evidence to determine the extent to which agreed-upon criteria are met. In a security context, this might involve assessing the effectiveness of controls, compliance with security policies and regulations, or the accuracy of system logging. Audits are essential for identifying vulnerabilities, ensuring accountability, and enhancing overall security posture.

Audit Accountability: The principle that ensures individuals or entities tasked with conducting audits are held responsible for their findings and actions. It requires that all audit activities, results, and decisions be properly documented, enabling transparency and traceability of the auditing process.

Audit Authority: The power or right granted to an individual or organization to conduct an audit. This authority is typically granted by a governing body or regulatory agency and may include the ability to access records, interview individuals, and make recommendations for improvement. Examples of organizations with audit authority include the Internal Revenue Service and the Securities and Exchange Commission.

Audit Charter: A formal document that outlines the purpose, authority, and responsibility of an audit activity. It provides a clear framework for the audit, including the scope of work to be performed, the standards to be adhered to, and the reporting process. An audit charter is essential for setting expectations, ensuring transparency, and fostering a cooperative relationship between the auditors and those being audited.

Audit evidence: The information collected during an audit process to support the auditor's conclusions. This could involve documentation, data analysis, physical checks, interviews, and other information sources. The evidence should be sufficient and appropriate in quality, and it aids in identifying anomalies, validating compliance, and assessing the effectiveness of controls in place.

Audit Expert Systems: Computer-based systems that utilize specialized knowledge and databases to assist auditors in the decision-making process during an audit. These systems enable the processing and analysis of complex data sets to enhance the quality and efficiency of audits.
