Question 1

What is an IT audit?

Accepted Answer

An IT audit is a systematic examination of an organization's information technology infrastructure, policies, and operations. It evaluates whether IT controls adequately protect assets, maintain data integrity, and support business objectives. IT audits can be internal (self-assessment) or external (independent verification).

Question 2

What are IT General Controls (ITGCs)?

Accepted Answer

IT General Controls are foundational controls that apply across multiple systems and applications. They include: access to programs and data, program changes, program development, and computer operations. ITGCs provide the foundation that supports the reliability of application-specific controls.

Question 3

What is the difference between ITGCs and application controls?

Accepted Answer

ITGCs are broad controls governing the IT environment (access management, change management, operations). Application controls are specific to individual applications and ensure accuracy and completeness of transactions (input validation, processing controls, output controls). Both are typically evaluated in IT audits.

Question 4

What frameworks guide IT audits?

Accepted Answer

Common IT audit frameworks include: COBIT (Control Objectives for Information Technology), ISACA IT Audit Standards, ISO 27001 (information security), SOC 2 Trust Service Criteria, NIST Cybersecurity Framework, and PCI DSS (for payment card environments). Framework selection depends on audit objectives.

Question 5

What areas should an IT audit cover?

Accepted Answer

Comprehensive IT audits typically cover: IT governance, access management, change management, IT operations, data management, network security, physical security, business continuity/disaster recovery, third-party/vendor management, and compliance with applicable regulations.

Question 6

How do I prepare for an IT audit?

Accepted Answer

Preparation steps include: understanding the audit scope and criteria, gathering relevant documentation (policies, procedures, evidence), ensuring systems can demonstrate control operation, briefing key personnel, addressing known issues proactively, and conducting pre-audit self-assessment to identify gaps.

Question 7

What evidence is needed for IT audits?

Accepted Answer

Common evidence includes: policies and procedures, access lists and user reviews, change tickets and approvals, system configurations, log samples, backup verification records, incident records, training records, vendor assessments, and penetration test reports. Evidence should demonstrate control design and operating effectiveness.

Question 8

What is control testing in IT audits?

Accepted Answer

Control testing evaluates whether controls are properly designed (design effectiveness) and operating as intended (operating effectiveness). Testing methods include inquiry, observation, inspection of evidence, and re-performance. Auditors select samples and test controls to conclude on their effectiveness.

Question 9

What are common IT audit findings?

Accepted Answer

Common findings include: excessive or inappropriate user access, weak password policies, missing or inadequate documentation, incomplete change management processes, outdated vulnerability patches, inadequate backup testing, missing audit logs, insufficient employee training, and gaps in vendor management.

Question 10

How often should IT audits be conducted?

Accepted Answer

Frequency depends on requirements and risk: SOC 2 requires annual audits for Type II reports, ISO 27001 has annual surveillance audits, internal IT audits are typically annual. High-risk areas may warrant more frequent assessment. Continuous auditing approaches are increasingly common.

Question 11

What is the difference between SOC 1 and SOC 2 audits?

Accepted Answer

SOC 1 (SSAE 18) focuses on controls relevant to financial reporting-used by service organizations that impact client financial statements. SOC 2 focuses on security, availability, processing integrity, confidentiality, and privacy-broader scope for technology and cloud service providers.

Question 12

How do I prioritize IT audit findings?

Accepted Answer

Prioritize findings based on: risk level (likelihood and impact of control failure), regulatory or compliance implications, potential financial exposure, ease of exploitation, and compensating controls. Critical and high-risk findings should be remediated urgently; lower-risk findings can be scheduled appropriately.

Question 13

What is a management response to audit findings?

Accepted Answer

Management responses document how the organization will address each finding, including: agreement or disagreement with the finding, planned remediation actions, responsible parties, target completion dates, and interim risk mitigation. Responses demonstrate accountability and commitment to improvement.

Question 14

What is continuous auditing?

Accepted Answer

Continuous auditing uses technology to automatically assess controls on an ongoing basis rather than periodically. It involves automated testing, real-time monitoring, and analytics to identify control deviations promptly. This approach provides more timely assurance and supports continuous improvement.

Question 15

How do IT audits support compliance programs?

Accepted Answer

IT audits verify that controls required by regulations and frameworks are implemented and effective. They provide independent assurance to management and boards, identify compliance gaps before regulators do, support attestation requirements (SOC 2, ISO 27001), and demonstrate due diligence.
