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 organization’s operations.
01

Why Perform an Audit - Key Objectives
Compliance with Laws and Regulations: Ensures that the financial and
operational behavior of an organization complies with relevant legal
requirements.
Internal Controls Assessment: Evaluates the effectiveness and efficiency
of internal controls and the operating procedures of the organization.
Fraud Detection and Prevention: Helps in detecting and preventing
fraud and errors in the accounting processes.
Verification of Records: Verifies that the assets and liabilities of an
organization are real and accounted for correctly.
Assurance of Accuracy: Ensures the accuracy and completeness of the
financial records and compliance with the applicable accounting
standards and regulations.
02

Types of Audit (Party-based )
Type of Audit
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 company’s own
internal audit staff.
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.
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.
Second-Party
Audit
Third-Party
Audit
Description Example
03

Key Differences
Ownership and Interest:
First-party 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)
Why Companies Conduct IT Audits?
Information Systems Audit: Deals with reviewing and evaluating the
information systems, methodologies, and operations of an organization.
Compliance Audit: Checks whether a body is following internal and
external regulations and agreements.
Operational Audit: Examines the effectiveness, efficiency, and economy
of an organization’s operations. It is more comprehensive than a financial
audit as it looks at underlying operations rather than just financial records.
Financial Audit: Focuses on determining whether an organization’s
financial statements present a fair and accurate view of its financial
position during the audit period.
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.

Protect and secure data and information systems.
Enhance the efficiency of IT processes.
Mitigate risks associated with data, security breaches, and technology
systems.

A typical day in the life of an IT Auditor
The day-to-day life of an IT auditor can vary depending on the type of
organization they work for, the specific project they are on, and where
they are in the audit cycle. However, a typical day often involves a
combination of technical assessment, communication, and reporting.
Here’s a generalized breakdown of an ideal day in the life of an IT auditor:
Morning
• Reviewing Audit Plans and Objectives: The day might start with
reviewing the audit schedule and objectives for the current projects. This
includes preparing audit checklists and tools needed for the day’s tasks.
• Team Briefing: If part of a larger audit team, the morning might include
a brief meeting to coordinate with other team members, discuss any
challenges, and distribute tasks.
Mid-Morning to Early Afternoon
• Fieldwork: This is the core of the auditor's day, involving data collection,
testing IT controls, and interviewing key personnel to understand and
document IT processes. Fieldwork could involve:
◦ Testing network security measures.
◦ Reviewing system access protocols.
◦ Assessing compliance with data protection laws.
◦ Evaluating disaster recovery plans and backup procedures.

Afternoon
• Data Analysis: After collecting information, the next step is to analyze
the data to identify discrepancies, risks, or inefficiencies. This may
involve using specialized audit software.
• Problem Solving and Consultation: Addressing any issues discovered
during the analysis with IT and business managers to understand the
reasons behind anomalies and discuss potential improvements.
Late Afternoon
• Documentation: Documenting the findings is crucial. This includes
writing up detailed reports that outline what was tested, what was
found, and the implications of those findings.
• Follow-Up Meetings: Sometimes, additional meetings with IT staff or
management are necessary to clarify certain points or gather more
information.
End of Day
• Planning for the Next Day: Reviewing what was accomplished during
the day and preparing for the next steps in the audit process.
• Learning and Professional Development: Keeping up-to-date with
the latest in IT and audit standards, which might involve reading
industry publications or taking online courses.
