IIA Updated IIA-CIA-Part3 Exam Questions and Answers by clark

Preventive security controls proactively stop unauthorized access before it occurs. The most effective method is strict access management, where new or additional access rights require formal validation before being granted.

Prevents Unauthorized Entry – Ensures that only approved personnel have access to the power plant.

Implements Segregation of Duties (SoD) – Supervisors validate access requests, reducing insider threats.

Aligns with Least Privilege Principle – Employees get only the minimum access necessary for their role.

Prevents Security Risks Before They Happen – Unlike detective or corrective controls, this method stops unauthorized access before it occurs.

A. Offboarding procedure (monthly review) – This is a detective control, identifying issues after access is granted, not preventing them.

B. Smart lock anomaly scanning – Also detective, as it identifies suspicious behavior after access has been used.

D. Automatic notifications for after-hours entry – A corrective control, responding to potential violations instead of preventing them.

IIA’s GTAG on Identity and Access Management – Recommends pre-approval processes for sensitive locations.

ISO 27001 Annex A.9 (Access Control) – Requires role-based access management for critical infrastructures.

NIST SP 800-53 (Security and Privacy Controls for Federal Information Systems) – Defines supervisor approval as a key preventive measure.

Why Approval-Based Access Control is the Best Preventive Measure?Why Not the Other Options?IIA References:

According to the Standards, internal audit activities can be provided through in-house resources, outsourcing, or a co-sourcing model. Therefore, it is possible for all resources to come from outside the organization, but ultimate responsibility and accountability remain with the CAE, management, and the board.

Option A is incorrect because oversight cannot be outsourced. Option B is incorrect—coordination with other assurance providers typically increases efficiency. Option D misstates requirements; co-sourcing is an option, not a mandatory practice.

When performing data analytics, the process typically follows a structured approach. Once the internal auditor has determined the expected value from the review, the next logical step is to obtain the data. Without acquiring the necessary datasets, further actions such as normalization, risk identification, and analysis cannot be effectively carried out.

(A) Incorrect – Normalize the data.

Normalization is a preprocessing step that occurs after data has been obtained.

Before normalizing, the auditor must first access and collect relevant data sources.

(B) Correct – Obtain the data.

Data acquisition is a critical step in data analytics.

The auditor must gather relevant and reliable data from internal and external sources before proceeding with further steps such as cleansing, normalization, and analysis.

(C) Incorrect – Identify the risks.

Risk identification is an essential part of the audit process but typically comes after obtaining and reviewing data patterns.

Without data, identifying risks would be speculative rather than evidence-based.

(D) Incorrect – Analyze the data.

Data analysis comes after obtaining, cleaning, and structuring the data.

Jumping straight to analysis without ensuring data quality would lead to inaccurate conclusions.

IIA’s GTAG (Global Technology Audit Guide) – Data Analytics

Recommends obtaining data as the initial step in data-driven audits.

IIA’s Global Internal Audit Standards – Use of Data Analytics in Auditing

Stresses the importance of data acquisition before proceeding with normalization and analysis.

COSO’s ERM Framework – Data-Driven Decision Making

Highlights the importance of securing data for risk identification and mitigation.

Analysis of Answer Choices:IIA References and Internal Auditing Standards:

When management has not implemented agreed action plans, the internal audit team must escalate the matter to the CAE. The CAE is responsible for discussing such cases with senior management to understand the reasons and determine next steps.

Option A is inappropriate because it is management’s responsibility—not internal audit’s—to propose action plans. Option B disregards the initial high-risk issue. Option C (escalation to the board) is premature unless senior management fails to act.

Thus, the correct response is Option D: report to the CAE, who should discuss with senior management.
