SIA 210 establishes the internal auditor’s core responsibility to acquire and maintain comprehensive knowledge of the entity and its environment for every engagement. This standard mandates a systematic process for gathering information, starting with preliminary knowledge before acceptance to confirm competence and resources. Following engagement acceptance, the auditor must acquire detailed knowledge encompassing the entity’s nature, operations, governance, financial structure, business objectives, associated risks, key internal controls, information systems, industry landscape, and the applicable regulatory framework. The central purpose of this knowledge acquisition is not merely documentation, but its effective application throughout the audit process. The auditor must use this understanding to accurately identify significant risks, tailor the nature, timing, and extent of audit procedures, evaluate the adequacy of controls, and recognize anomalies or indicators of fraud. Finally, the standard requires thorough documentation of the acquired knowledge and its application within the internal audit working papers, ensuring relevance, effective planning, and value-added conclusions. This standard applies universally across all internal audit engagements.

Application and Other Explanatory Material
A1. Preliminary Knowledge Prior to Engagement (Refer Para. 4.1): Obtaining preliminary knowledge before engagement acceptance enables the internal auditor to evaluate whether the assignment can be performed with the required competence, independence, and resources.
Such knowledge may be derived from publicly available sources, such as annual reports, industry publications, regulatory filings, previous audit or review reports, and preliminary discussions with management.
A2. Acquisition of Detailed Knowledge Post-Acceptance (Refer Para. 4.2):
(a) Knowledge of the entity’s ownership, governance, and financing structures aids in assessing key areas of risk and determining the focus of internal audit work.
(b) Awareness of the entity’s objectives and strategies helps in identifying strategic, operational, and compliance risks that may impact performance.
(c) Familiarity with information systems enables the internal auditor to evaluate internal controls and identify opportunities for data-driven audit techniques.
(d) Industry and environmental factors, such as competition, technological disruption, or macroeconomic conditions, may significantly influence the entity’s risk profile.
(e) Once the engagement is accepted, a deeper understanding of the entity and its environment is necessary to identify and assess risks of material misstatement, fraud, or noncompliance.
(f) Understanding the applicable regulatory framework assists the internal auditor in evaluating compliance obligations and reporting requirements relevant to the entity.
A3. Application of Knowledge in Audit Process (Refer Para. 4.3): Acquired knowledge guides the internal auditor in tailoring audit procedures to identified risks. For example, heightened risks in inventory management may require expanded testing of stock records and related controls.
The internal auditor uses this knowledge to assess whether internal controls are effectively designed and operating, and whether audit evidence gathered is sufficient and reliable.
Awareness of the entity’s environment assists the internal auditor in identifying anomalies or red flags, such as unusual transactions, patterns, or deviations that may suggest fraud or error.
A4. Documentation of Knowledge Obtained (Refer Para. 4.4): Proper documentation demonstrates that the internal auditor has obtained sufficient understanding of the entity and applied it in planning and performing the engagement. It also facilitates supervision, quality reviews, and future reference.
Documentation may include internal memos, industry reports, organizational charts, minutes of meetings, process flowcharts, regulatory references, working papers on risk assessments, etc.
