Mock IT Auditor Interview: Typical Questions Guide

1

How do you perform a risk assessment that actually drives your audit plan (instead of being a formality)?

Reference answer

I start by linking the risk assessment to how the company makes money, where judgment lives, and where controls could realistically fail. I meet with process owners, review prior findings, scan board minutes and key contracts, and use analytics to spot unusual trends before I write the plan. Then I translate risks into specific assertions—like revenue cutoff, inventory valuation, or completeness of liabilities—and document why each risk matters. The audit plan becomes a direct response: which controls I'll rely on, which accounts get deeper substantive work, where specialists are needed, and how sampling sizes shift. If conditions change mid-audit, I refresh the risk assessment and re-scope.

2

What does a typical day look like in IT audit?

Reference answer

Trace a typical day through the IT audit phases—planning, field work, and reporting—balancing walkthroughs, testing controls, gathering evidence, and drafting reports with remediation follow-up.

3

How do you assess and manage risk during an audit?

Reference answer

Assessing and managing risk during an audit involves identifying, evaluating, and prioritizing risks, and implementing appropriate audit procedures to address them. I start by conducting a risk assessment, which includes reviewing prior audit reports, understanding the business processes, and identifying key risk areas. I then evaluate the likelihood and impact of each risk and prioritize them based on their significance. During the audit, I design and perform targeted audit procedures to address the identified risks, ensuring that sufficient evidence is obtained to support my conclusions.

4

Can you describe your experience with fraud detection and prevention?

Reference answer

I have experience with fraud detection and prevention through various audit engagements. My responsibilities have included assessing the risk of fraud, designing and performing audit procedures to detect potential fraud, and evaluating the effectiveness of internal controls to prevent fraud. I have identified instances of fraud through data analysis, interviews, and detailed testing of transactions. In cases where fraud was detected, I worked with management to implement corrective actions and improve controls to prevent future occurrences. My experience has equipped me with the skills to identify and address potential fraud risks effectively.

5

What is audit risk, and how do inherent risk and control risk shape your approach?

Reference answer

Audit risk is the risk that I issue an inappropriate opinion when the financial statements are materially misstated. I manage it by tailoring the nature, timing, and extent of procedures based on risk. Inherent risk reflects how susceptible an area is to misstatement—complex estimates, revenue recognition, or unusual transactions raise it. Control risk reflects whether the client's controls prevent or detect misstatements effectively. If inherent risk is high but controls are strong and tested as effective, I may rely more on controls and targeted substantive work. If control risk is high, I expand substantive testing and increase skepticism.

6

Tell me about your weaknesses.

Reference answer

Learn to answer tell me about your weaknesses by acknowledging genuine, non-critical areas and detailing concrete improvement steps, illustrated with public speaking practice, Toastmasters, and real progress.

7

How would you assess the adequacy of an organization's IT controls?

Reference answer

To establish whether IT controls are sufficient, it is necessary to review and assess a number of organisational IT infrastructure components, including access controls, data security, change management, and disaster recovery. This assessment may involve conducting interviews, evaluating documentation, testing the system, and looking at compliance to see whether controls are effective in lowering risks.

8

How do you handle situations where controls exist but are not consistently performed?

Reference answer

First, I confirm the facts—whether the control failure is isolated or recurring—by expanding the period coverage and reviewing evidence of performance. If inconsistency is confirmed, I assess why: unclear ownership, lack of training, poor documentation, system limitations, or unrealistic timelines. From an audit perspective, I treat inconsistency as a reliability issue: I reduce or eliminate reliance on the control and increase substantive testing in the related areas. I also evaluate whether the inconsistency creates a control deficiency that should be communicated, and I document the impact on audit strategy clearly. When appropriate, I discuss practical remediation with management—simplifying the control, strengthening monitoring, or automating steps—so the fix is sustainable and not just "try harder next month."

9

How would you audit a Purchase-to-Pay (P2P) cycle?

Reference answer

Break it down by sub-process: - Vendor onboarding - Purchase requisition and approval - PO generation - Goods receipt/3-way match - Invoice processing - Payment authorization Then talk about: - Key risks (e.g., duplicate payments, unauthorized purchases) - Key controls (e.g., segregation of duties, system validations) - Sample tests and data analytics (e.g., PO vs invoice mismatches) This is a favorite among Big 4s.

12

How do you handle a situation where you suspect fraud or unethical behavior?

Reference answer

If I suspect fraud or unethical behavior during an audit, I follow a structured approach to investigate and address the issue. I start by gathering and analyzing relevant evidence to confirm the suspicion. I maintain confidentiality and avoid making premature conclusions. If the suspicion is confirmed, I report the findings to senior management or the appropriate authorities, following the organization's policies and procedures. I also work with management to implement corrective actions and strengthen controls to prevent future occurrences. Maintaining professionalism and integrity is crucial in handling such situations.

13

What challenges do auditors face when assessing virtualized environments, and how can these be mitigated?

Reference answer

Auditing virtualized environments poses challenges such as complex configurations, dynamic nature of virtual resources, and difficulty in tracking and managing virtual machine sprawl. Mitigating these challenges involves using specialized tools to monitor and manage virtual environments, ensuring proper configuration management practices are in place, and regularly reviewing security controls. Training auditors in virtualization technology and its security implications is also crucial.

14

A significant number of employees work remotely. How will the company ensure data security and privacy in this remote work environment?

Reference answer

I recommend implementing some sort of remote work security plan, including the use of VPNs, secure access points, regular security training for remote users, and strict policies will be used in incident response in remote threat specific include.

15

The Company's IT systems are outdated and out of step with industry standards. How do you recommend we should update and improve it?

A global standard for information security management systems (ISMS) is ISO 27001. It offers a structure for establishing, carrying out, maintaining, and continuously enhancing information security within an organization. IT auditors use ISO 27001 as a standard to evaluate the suitability and efficacy of security measures and ISMS in an enterprise.

19

How do you set performance materiality and tolerable misstatement for testing?

Reference answer

I treat performance materiality as a practical safeguard against aggregation risk—multiple small errors adding up to something material. After setting overall materiality using an appropriate benchmark, I adjust performance materiality based on factors like control strength, prior misstatements, estimate complexity, and fraud risk. Strong controls and clean history may support a higher percentage; weak controls, high judgment, or past issues drive it lower. For tolerable misstatement at the account level, I allocate performance materiality based on account size and risk and ensure it aligns with my sampling approach. I also revisit these thresholds if business conditions shift, so testing remains proportionate and defensible.

20

What is the purpose of a Business Continuity Plan (BCP) and how does it relate to IT Audit?

Reference answer

A Business Continuity Plan (BCP) outlines procedures to maintain or restore business operations in the event of a disruption. In IT Audit, we evaluate the BCP to ensure it is comprehensive, tested regularly, and aligned with IT disaster recovery plans to minimize downtime and data loss.

21

What is the significance of ISACA's IT Audit and Assurance Standards in conducting audits?

Evaluating an organization's risk management processes involves assessing the design and effectiveness of risk identification, assessment, and mitigation procedures. I start by reviewing the organization's risk management framework and policies. I conduct interviews with key personnel to understand the risk management practices and assess the alignment with industry best practices. I evaluate the effectiveness of risk assessment procedures, risk monitoring, and reporting mechanisms. By identifying gaps and recommending improvements, I help the organization enhance its risk management processes and better manage potential risks.

25

Can you explain your process for planning an audit?

Reference answer

Planning an audit involves several key steps: understanding the audit objectives and scope, conducting a preliminary risk assessment, and developing an audit plan. I start by meeting with stakeholders to understand their concerns and expectations. I then gather and review relevant documentation to gain a preliminary understanding of the audit area. Based on this information, I conduct a risk assessment to identify areas of potential concern and prioritize audit procedures accordingly. Finally, I develop a detailed audit plan that outlines the audit objectives, scope, methodology, timeline, and resource requirements.

26

How do you handle disagreements with clients about audit findings?

Reference answer

I approach disagreements as opportunities for dialogue rather than confrontation. First, I make sure I fully understand the client's perspective by asking questions and listening carefully. Then I walk them through our audit evidence step-by-step, explaining our methodology and why we reached our conclusion. I had a situation where a client disagreed with our assessment of their allowance for doubtful accounts. Instead of just stating our position, I showed them our analysis of their collection history, industry benchmarks, and specific customer payment patterns. This helped them understand our reasoning, and we worked together to develop improved collection procedures.

27

Internal IT audits are conducted by a company's internal audit department or individual auditors to assess internal controls, compliance, and operational effectiveness. They serve as a proactive measure to identify and address issues within the organization. Independent audit companies or governmental organizations carry out external IT audits. They concentrate on giving external stakeholders, including shareholders, investors, or regulatory bodies, an unbiased review of an organization's IT controls, financial statements, and regulatory compliance.

59

How do you audit automated controls and key reports after a major system implementation?

Reference answer

After a major implementation, I assume elevated risk until proven otherwise. I start by understanding what changed—process flows, configurations, interfaces, and user roles—and identify controls that were newly created, modified, or replaced. I test IT general controls first, because automated controls and reports are only reliable if access and change management are effective. Then I test automated controls for design and operating effectiveness using test transactions, evidence from system logs, and re-performance where possible. For key reports, I validate completeness and accuracy and confirm that report parameters are controlled. I also focus on migration risks—opening balances, master data quality, and interface reconciliations. If I find issues, I increase substantive testing and recommend practical stabilization steps like stronger monitoring, exception reporting, and role clean-up.

60

Tell me about a time you disagreed with a supervisor.

Reference answer

Respectful resolution.

61

What's your approach to staying organized during a complex, multi-system audit?

Reference answer

I'm a big believer in upfront structure. Before I start any audit fieldwork, I create a detailed audit program that maps testing procedures to specific risks and objectives. I build in checkpoints where I'll synthesize what I've found and adjust if needed. I use a combination of tools—spreadsheets for data analysis, audit management software for tracking issues, and shared drives for documentation. I also maintain a running summary document during fieldwork where I jot down observations, preliminary findings, and questions. This prevents me from reaching the end of an audit with mountains of notes and no clear picture. I also try to debrief with my team weekly during longer audits to make sure we're aligned and any issues surface early. For example, on a three-month SOC 2 audit, I had team members assigned to different control areas. Our weekly meetings ensured no one was testing the same thing twice, and we could flag dependencies early.

62

How do you document test results and working papers?

Reference answer

Document test results and working papers using audit tools like AuditBoard, RSA, Archer, and ServiceNow. Evidence and documents are uploaded to AuditBoard, with supporting files on SharePoint or shared drives.

63

The organization is migrating to cloud-based services. How would you assess the security risks associated with this migration?

Reference answer

I would examine the cloud provider's security controls, perform a data classification assessment, and review the organization's access controls and encryption practices. It is important to ensure that security measures align with industry standards and best practices.

64

How do you stay current with the latest trends and risks in IT auditing?

Networking with other IT auditors and professionals allows me to share insights and stay informed about the latest trends and risks in the field.

65

Can you explain your process for testing and evaluating internal controls?

Reference answer

My process for testing and evaluating internal controls involves understanding the control environment, identifying key controls, and performing detailed testing. I start by reviewing documentation and conducting interviews to understand the design and implementation of controls. I identify key controls that are relevant to the audit objectives and assess their design effectiveness. I then perform testing, which may include walkthroughs, sample testing, and data analysis, to evaluate the operational effectiveness of the controls. I document the results and provide recommendations for improving controls where necessary.

66

You discover your senior made a significant testing error. They ask you to stay quiet. What do you do?

Reference answer

Professional integrity requires addressing this immediately. I'd first ensure I fully understand the error and its implications. Then I'd explain to the senior that we need to correct this together, emphasizing that early correction is better than later discovery. If they refuse, I'd escalate to the manager or partner, focusing on the issue rather than personalities. Documentation integrity is fundamental to audit quality. This situation also suggests a need for improved review procedures. Throughout, I'd maintain professionalism, recognizing that everyone makes mistakes, but covering them up is unacceptable.

67

If you suspected a company was exposed to a major risk, what risk management procedures would you use?

Reference answer

The candidate should discuss risk identification, assessment, mitigation strategies, and monitoring procedures, including the use of risk matrices, internal controls evaluation, and escalation to management.

68

What's your understanding of IT governance frameworks like COBIT, and how do you use it in auditing?

Reference answer

COBIT provides a framework for evaluating IT governance across multiple domains—everything from strategy to risk to security to vendor management. Rather than just checking if a control exists, COBIT helps me understand whether the organization has the right capabilities to support their business objectives. I use it to structure my audit approach. For example, I might focus on the 'Manage Changes' process. COBIT tells me that this process should include change planning, approval criteria, testing, approval, and monitoring. I'll test whether they actually have these activities, whether they're documented, and whether they're operating effectively. I've also used COBIT's maturity levels to help organizations understand that they're not broken—they're just at a different maturity level and need to evolve their practices over time. That reframing often makes recommendations less defensive because it's not 'you're doing it wrong,' it's 'here's the next level of maturity.'

69

How do you evaluate the effectiveness of controls implemented to meet compliance standards during an IT audit?

Reference answer

Looking for methods and procedures used by the candidate to assess the adequacy and effectiveness of compliance controls.

Reference answer

I was working on a complex manufacturing audit with a senior associate who was very resistant to using data analytics tools, preferring traditional testing methods even when they were less efficient. This was slowing down our entire team's progress, and I could see tension building. Rather than complaining to our manager, I asked if I could walk them through how the analytics tools worked and show some successful examples from other engagements. I discovered they were actually intimidated by the technology, not opposed to efficiency. I offered to set up the initial analytics and teach them the process gradually. We started with simple procedures like duplicate payment testing, and I showed them how much time it saved. Once they saw the benefits and gained confidence with the tools, they became one of their biggest advocates. Our audit finished ahead of schedule, and this person now regularly mentors others on analytics techniques.

76

Can you describe your experience with internal and external audits?

Reference answer

I have extensive experience with both internal and external audits. As an internal auditor, I conducted comprehensive audits of financial and operational processes, identified control weaknesses, and recommended improvements.

79

What is your experience with VMware and other virtualization tools in the context of IT auditing?

Reference answer

The candidate should detail their hands-on experience with VMware for auditing virtual environments, including checking configurations, security settings, and compliance with policies.

80

How do you determine whether a control deficiency is significant—and how do you document that judgment?

Reference answer

I assess significance by considering the likelihood and magnitude of potential misstatement, the nature of the account and assertion, and whether there are compensating controls. I look at the frequency of failure, the population affected, and whether the deficiency relates to fraud risk or management override. I also consider whether similar issues exist across processes, which can point to a broader control environment problem. Documentation is critical: I write the condition, criteria, cause, and potential effect, and I tie it to the specific financial reporting risk. I include my evaluation of severity, any testing results that support the assessment, and my conclusion on whether it's a control deficiency, significant deficiency, or material weakness under the relevant framework and reporting requirements.

81

It is a comprehensive framework that assists organizations in achieving their objectives for the governance and management of enterprise IT by ensuring alignment with business goals, managing IT risks effectively, and providing an audit trail.

89

How do you protect independence when a client pressures you to "help fix" issues during the audit?

Reference answer

I'm helpful, but I stay on the right side of independence by distinguishing between identifying issues and designing solutions. I can explain the criteria, describe the risk, and share leading practices at a high level, but I avoid taking on management responsibilities—like drafting controls, approving journal entries, or implementing processes. When pressure arises, I reset expectations: our role is to evaluate and report, not to operate the client's control environment. If management needs help, I suggest they use internal resources or separate advisory teams with proper safeguards. I document the request and my response, and I involve the engagement leader when the line feels blurry. Independence isn't just compliance—it's what makes our opinion credible to stakeholders.

90

Can you describe your educational background in IT or computer science and how it has prepared you for a Senior IT Auditor role?

Reference answer

Give an example of teamwork under pressure.

Reference answer

Role, collaboration, outcome.

94

How do you ensure that IT audit recommendations are implemented?

Reference answer

I work closely with stakeholders to develop action plans that address audit findings and recommendations. I track progress against the action plan and provide regular updates to management. I also follow up on outstanding issues and escalate to management as needed.

95

How do you perform a penetration test as part of an IT audit:

Reference answer

Penetration testing involves simulating cyberattacks to assess an organization's security defenses. Typically, the test's scope, goals, and ground rules are established by the auditor. System, network, or application vulnerabilities are attempted to be exploited by testers, who then report their results and offer mitigations. To improve security and compliance, it is essential to find flaws before hostile actors may take advantage of them.

96

Explain how you would approach auditing an organization's disaster recovery plan. What key elements would you assess for technical proficiency?

Reference answer

Candidate should demonstrate in-depth understanding of disaster recovery planning and articulate key factors such as business continuity, data integrity, recovery objectives (RTO and RPO), and testing protocols. Expect technical proficiency in evaluating the efficacy and completeness of the plan.

97

A client consistently provides requested documents late. How do you address this?

Reference answer

I'd first analyze patterns to understand root causes, whether it's resource constraints, system issues, or prioritization problems. Then I'd schedule a meeting with the client to collaboratively develop solutions. This might include creating detailed request lists earlier, providing templates to simplify preparation, or adjusting timing to align with their workflows. I'd emphasize how delays increase both audit costs and business disruption. If issues persist, I'd escalate to senior management, highlighting regulatory deadline risks. Throughout, I'd maintain professionalism while firmly communicating requirements.

98

How do you handle feedback and criticism? Can you share an example from your past experience?

Reference answer

I view feedback as a tool for growth. It's essential in refining my auditing skills and improving performance. For instance, in my previous role, I received feedback about my report writing style. My supervisor felt they were too technical for non-IT staff to comprehend. This experience reaffirmed the importance of feedback in professional development.

103

Explain the process of a risk-based audit in IT.

Reference answer

A risk-based IT audit focuses on the areas of greatest risk to an organization's IT environment. The process starts with a risk assessment to identify and prioritize risks based on their potential impact and likelihood. This assessment informs the audit scope and objectives, focusing resources on the systems and processes that pose the highest risk. During the audit, controls are tested for effectiveness in mitigating identified risks, and any deficiencies are noted for remediation. The outcome is a report that provides insights into risk exposures and recommendations for enhancing the IT risk management framework.

104

What is an IT audit and its importance?

Reference answer

106

Describe how you would audit a complex revenue model with multiple performance obligations and variable consideration.

Reference answer

I begin by understanding the revenue model end-to-end: contract types, pricing mechanics, fulfillment steps, and system configuration. Then I select contracts across products and terms to test how performance obligations are identified, how the transaction price is allocated, and when revenue is recognized. For variable consideration, I evaluate the estimation method, constraint assessment, and the data supporting assumptions—returns, rebates, usage, and milestone probabilities. I also test contract modifications, since they're a frequent source of errors. Substantively, I trace from contract to billing to fulfillment evidence, and I reconcile deferred revenue movements. I use analytics to spot unusual trends and perform cutoff testing around period-end. If the judgments are significant, I involve specialists and ensure disclosures explain key estimates clearly.

107

How do you stay updated with the latest IT audit trends and technologies?

Reference answer

Employers want to know if you are proactive in keeping your skills current. Mention specific resources like industry publications, webinars, or professional organizations that help you stay informed.

108

How do you audit fair value measurements (Level 2 vs. Level 3), and when do you bring in specialists?

Reference answer

I start by classifying the valuation into Level 2 or Level 3 based on the observability of inputs, because that dictates the evidence required. For Level 2, I focus on validating pricing sources, market comparables, and observable inputs like yield curves, credit spreads, or quoted prices for similar instruments. For Level 3, I go deeper into model governance, unobservable inputs, and management judgment—cash flow forecasts, terminal values, discount rates, and calibration. I test the completeness and accuracy of underlying data, evaluate model reasonableness, and perform sensitivity analysis. I bring in valuation specialists when instruments are complex, the inputs are highly judgmental, the amounts are material, or when I need expertise to evaluate models and market assumptions. I also ensure disclosures appropriately describe valuation techniques and sensitivity.

109

What are the main objectives of an IT audit?

Reference answer

The main objectives of an IT audit are to evaluate the effectiveness of IT controls, ensure the integrity and confidentiality of data, verify compliance with regulations and policies, and assess the overall security and functionality of IT systems.

110

What would you do if someone asked you to do something unethical like covering up a fraud?

Reference answer

The candidate should emphasize adherence to ethical standards, refusal to comply, reporting the request through proper channels (e.g., whistleblower hotline or audit committee), and documenting the incident.

111

Tell me about a time you had to explain a complex audit result to executives who were short on time. How did you communicate it?

Reference answer

I discovered that our company's email system had lax retention policies—we were keeping emails indefinitely, which created data privacy and eDiscovery risks. I was scheduled to present findings to our C-suite for 15 minutes. I knew I couldn't explain the technical details of the email server in that time. Instead, I led with the business risk: 'We have seven years of email in our system. That creates two risks: if we're sued, we're sitting on a mountain of documents, and if we have a breach, that's years of confidential data exposed.' I then gave them three options: strict deletion policies (aggressive, cost), longer retention with better controls (moderate), or a hybrid approach. The CFO asked questions about compliance, which I answered with a one-pager I'd prepared. They chose option three, which I then worked with IT to implement.

112

How do you explain complex accounting issues to non-financial executives?

Reference answer

I use relatable analogies and focus on business impact rather than technical details. For example, when explaining lease accounting changes, I compare it to buying versus renting a house and how it affects their personal balance sheet. I create visual aids showing before-and-after impacts on key metrics they care about. I always start with the 'why it matters' before diving into the 'what changed.' This approach helps executives understand implications for debt covenants, investor communications, and strategic decisions. I also provide one-page summaries with clear action items.

113

In your opinion, what are the key components of an effective audit report, and how do you ensure these components are communicated to the reader?

Reference answer

The response should cover the candidate's understanding of critical elements such as executive summaries, clear findings, and actionable recommendations, and their ability to articulate these in written form.

114

How do you work independently and with a team?

Reference answer

Demonstrate your ability to work independently and with a team by highlighting traits that fit the job and the advantages of both, including collaboration and focused solo effort.

115

Can you describe an audit control procedure and its purpose?

Reference answer

This question is typically asked of audit managers but can also be used when interviewing junior auditors. It confirms that you understand every aspect of the auditing process and each one's impact on the work you will be doing. Example: “Audit control procedures are a documented set of processes and policies which dictate the scope and methodology for an audit. They are usually drafted by the organization's key stakeholders and approved by the owners or directors. The purpose of audit control procedures is to establish the goal of the audit and to set up some controls for the audit team.”

116

What are the differences between an internal and external audit?

Reference answer

An internal audit involves reviewing a company's procedures, and internal auditing teams complete internal audits periodically. These audits ensure efficiency and accuracy in business practices. An external audit is performed by an external auditor hired by a company. External audits typically involve checking if the company meets compliance or regulatory requirements, but an external audit can also confirm the findings of an internal audit. The U.S. Securities and Exchange Commission (SEC) requires periodic audits of all publicly traded companies.

117

What does "professional skepticism" mean in practice, and how do you demonstrate it?

Reference answer

Professional skepticism means maintaining a questioning mindset and critically evaluating evidence rather than assuming management is right or wrong. In practice, I demonstrate it by challenging explanations with corroboration, looking for contradictory evidence, and following up on anomalies until they're resolved. For example, if margin improves unexpectedly, I don't accept "pricing power" at face value; I reconcile it to sales mix, discounts, returns, and cutoff testing. I also focus on areas prone to management bias, like estimates, journal entries, and unusual period-end transactions. Skepticism shows up in my documentation—clear rationale, evidence linkage, and why I concluded the risk was addressed.

118

Discuss the role of data analytics and data mining in IT auditing:

Reference answer

By enabling auditors to examine enormous datasets for trends, anomalies, and insights, data analytics and data mining play a crucial role in IT auditing. By analyzing transactional data, logs, and user behavior, data analytics can spot possible hazards, fraud, or abnormalities. Data mining assists in risk assessment and fraud detection by enabling auditors to find hidden linkages and trends within the data. Both methods increase audit effectiveness by enabling auditors to concentrate on high-risk areas and offer suggestions based on data.

119

What are substantive tests in auditing?

Reference answer

Substantive tests verify the financial statements by: testing details of transactions and balances, performing analytical procedures, and obtaining direct evidence to detect material misstatements.

120

How do you stay current with evolving IT risks and regulatory requirements?

Reference answer

I subscribe to several industry resources, including the ISACA Journal and the IIA's audit updates. I'm also active in a local ISACA chapter where we discuss emerging threats and new frameworks. Earlier this year, I completed a webinar on the evolving requirements of GDPR as it applies to cloud environments, which was incredibly relevant because my organization had just migrated to Azure. I immediately documented how our current audit procedures needed to evolve to address cloud-specific risks like data residency and API security. I then trained my team on these new considerations before our next audit cycle.

121

If you spotted a minor bug in an application, would you try to fix it yourself or mention it to the engineering team?

Reference answer

I would report the bug to the engineering team through the proper channels, such as a ticketing system, to ensure it is documented and addressed according to established procedures. As an IT Auditor, my role is to identify and report issues rather than implement fixes directly, unless I have explicit authorization and expertise. This ensures accountability and maintains the integrity of the development process.

122

Explain the IT audit's approach to risk assessment.

Reference answer

In IT auditing, the risk assessment strategies include: - Identify Assets: Catalog IT assets that need protection - Threat Identification: Determine potential threats to IT assets - Vulnerability Assessment: Identify weaknesses that could be exploited - Impact Analysis: Assess the potential impact of threats exploiting vulnerabilities - Likelihood Determination: Estimate the probability of threats occurring - Risk Evaluation: Analyze and prioritize risks based on impact and likelihood - Control Analysis: Review existing controls and their effectiveness - Recommendation for Improvement: Suggest measures to mitigate identified risks - Documentation and Reporting: Record findings and propose an action plan

123

A client's inventory turnover ratio dropped from 8.2 to 4.1 year-over-year. What's your investigation process?

Reference answer

This significant decline warrants immediate investigation. I'd start with analytical procedures comparing monthly trends, not just annual figures. Key areas to investigate include: obsolete inventory requiring write-downs, changes in supplier terms affecting purchasing patterns, potential demand shifts in the market, and accuracy of inventory counts. I'd perform physical inventory observations, test net realizable value calculations, and review aging reports. Additionally, I'd examine whether this indicates broader operational issues or potential manipulation of cost of goods sold.

124

What types of audits can be conducted in an IT audit context?

Reference answer

Types of audits include financial audits, operational audits, compliance audits, security audits, and integrated audits, each focusing on different aspects such as financial reporting, system performance, regulatory adherence, cybersecurity, and combined IT and business processes.
