Introduction An audit is a systematic and
independent examination of books, accounts,
statutory records, documents, and vouchers of an
organization to ascertain how far the financial
statements, as well as non-financial disclosures,
present a true and fair view of the concern. It
also attempts to ensure that the books of
accounts are properly maintained by the entity as
required by law. Audits provide an objective
assessment that aims to add value and improve an
organizations operations.

Why Perform an Audit - Key Objectives Assurance
of Accuracy Ensures the accuracy and
completeness of the financial records and
compliance with the applicable accounting
standards and regulations. Verification of
Records Verifies that the assets and liabilities
of an organization are real and accounted for
correctly. Fraud Detection and Prevention Helps
in detecting and preventing fraud and errors in
the accounting processes. Internal Controls
Assessment Evaluates the effectiveness and
efficiency of internal controls and the operating
procedures of the organization. Compliance with
Laws and Regulations Ensures that the financial
and operational behavior of an organization
complies with relevant legal requirements.

Types of Audit (Party-based )
Type of Audit Description Example
First-Party Audit Conducted internally by an organization to assess its own processes and systems. Often used for self-assessment and internal control verification. A company conducts an internal review of its IT security to ensure that all systems are secure and up-to-date with company policies. This audit is performed by the companys own internal audit staff.
Second-Party Audit Performed by an external party, but not an independent third-party. These are typically done by a customer auditing a supplier. A retail company audits a supplier to ensure that their IT systems comply with the retailer's data security requirements. The audit is performed by the retailer's audit team, not an independent auditor.
Third-Party Audit Conducted by an independent, external organization that has no direct interest in the outcome of the audit. Often results in certification or formal assessment. An accounting firm like Deloitte performs an IT security audit for a client company, resulting in a formal report that might be used for regulatory compliance or certification purposes.

Key Differences Ownership and Interest First-par
ty audits are self-performed and focus on
internal review and self-regulation. Second-party
audits are performed by someone who has a stake
in the audit outcome, such as a customer checking
a supplier. Third-party audits are conducted by
an independent body, ensuring an unbiased
perspective and often used for certification or
compliance purposes. Purpose and
Use First-party audits are primarily used for
internal management and continuous
improvement. Second-party audits are often
focused on verifying if the supplier meets the
customer's specific requirements. Third-party
audits provide external validation of compliance
with standards, which can be used for
certifications, regulatory requirements, and
public assurance.

Types of Audit (Scope-based) Financial Audit
Focuses on determining whether an organizations
financial statements present a fair and accurate
view of its financial position during the audit
period. Operational Audit Examines the
effectiveness, efficiency, and economy of an
organizations operations. It is more
comprehensive than a financial audit as it looks
at underlying operations rather than just
financial records. Compliance Audit Checks
whether a body is following internal and external
regulations and agreements. Information Systems
Audit Deals with reviewing and evaluating the
information systems, methodologies, and
operations of an organization.
Why Companies Conduct IT Audits? Compliance To
adhere to laws, regulations, and
standards. Security To identify vulnerabilities
and strengthen security measures. Performance To
improve the efficiency and effectiveness of IT
systems. Risk Management To proactively manage
and mitigate IT risks.

to ensure compliance with financial regulations,
