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

System software controls refer to security measures and protocols that protect an organization's IT infrastructure from unauthorized access, cyber threats, and system failures. Intrusion testing (penetration testing) is a key system software control used to detect vulnerabilities in IT environments.

Correct Answer (D - Performing Intrusion Testing on a Regular Basis)

Intrusion testing is a critical system software security measure that helps identify weaknesses in software configurations and security defenses.

This falls under system software controls because it directly tests the security of operating systems, applications, and network software.

The IIA’s GTAG 11: Developing IT Security Audits highlights penetration testing as a necessary control for system software security.

Why Other Options Are Incorrect:

Option A (Restricting server room access to specific individuals):

This is a physical access control, not a system software control.

Option B (Housing servers away from environmental hazards):

This is an environmental control, focusing on disaster prevention rather than software security.

Option C (Ensuring that all user requirements are documented):

This relates to project documentation and system development, but it does not control software security.

IIA GTAG 11: Developing IT Security Audits – Recommends regular penetration testing as a system software control.

IIA Practice Guide: Auditing IT Security – Discusses system software security measures.

IIA References for Validation:Thus, D is the correct answer because intrusion testing is a core system software control ensuring security.

Definition of Project Crashing:

Project crashing is a schedule compression technique used in project management to reduce the project completion time without changing its scope.

It involves adding extra resources (labor, equipment, budget) to critical path activities to complete them faster.

Key Aspects of Project Crashing:

Reduces project duration by increasing resources.

Leads to higher costs due to additional labor or expedited material procurement.

Used when project deadlines must be met and standard scheduling techniques are insufficient.

Why Other Options Are Incorrect:

A. It leads to an increase in risk and often results in rework:

While crashing can increase costs and risk, it does not necessarily result in rework unless poorly executed.

B. It is an optimization technique where activities are performed in parallel rather than sequentially:

This describes fast-tracking, not crashing. Fast-tracking involves overlapping tasks, while crashing adds resources to speed up tasks.

C. It involves a revaluation of project requirements and/or scope:

Crashing does not change project scope; it only shortens the schedule by allocating additional resources.

IIA’s Perspective on Project Risk and Management:

IIA Standard 2110 – Governance emphasizes the importance of project risk assessment, including schedule compression risks.

COSO ERM Framework identifies project cost overruns and resource misallocations as key risks in project execution.

PMBOK (Project Management Body of Knowledge) defines crashing as a schedule compression technique used when deadlines must be met at additional cost.

IIA References:

IIA Standard 2110 – Governance & Risk Oversight in Project Management

COSO Enterprise Risk Management (ERM) – Project Risk Considerations

PMBOK Guide – Schedule Compression Techniques (Crashing & Fast-Tracking)

Thus, the correct and verified answer is D. It is a compression technique in which resources are added so the project is completed faster.

In data analytics, cleaning the data is a crucial step where the auditor eliminates redundancies, corrects inconsistencies, and removes errors to ensure accurate analysis. This step is taken before analyzing the data to identify high-risk areas and relevant processes.

Correct Answer (C - Cleaning the Data in Preparation for Determining Involved Processes)

Data cleaning involves:

Removing duplicate entries to prevent misinterpretation.

Standardizing data formats for consistency.

Handling missing or inaccurate values to ensure reliability.

This step prepares the data for analysis and identification of high-risk processes.

The IIA’s GTAG 16: Data Analysis Technologies emphasizes data cleaning as a critical part of internal audit analytics.

Why Other Options Are Incorrect:

Option A (Normalizing data in preparation for analyzing it):

Normalization refers to structuring data efficiently (e.g., in databases) but does not necessarily involve eliminating redundancies in the way described.

Option B (Analyzing data in preparation for communicating results):

The auditor is still in the data preparation phase, not the analysis or reporting phase.

Option D (Reviewing data prior to defining the question):

The auditor is already working with data. Defining questions typically happens before data collection.

GTAG 16: Data Analysis Technologies – Covers data preparation, cleaning, and analytics in internal auditing.

IIA Practice Guide: Data Analytics in Internal Auditing – Outlines best practices for data validation and cleaning.

Step-by-Step Explanation:IIA References for Validation:Thus, cleaning the data (C) is the correct answer, as it ensures data integrity before identifying relevant processes and risks.

Understanding BYOD Risks:

A Bring-Your-Own-Device (BYOD) policy allows employees to use personal devices (e.g., laptops, smartphones, tablets) for work.

This increases security risks such as unauthorized access, malware infections, data leakage, and non-compliance with IT security policies.

Why Option C (Detection and Authentication Controls) Is Correct?

Detection and authentication controls ensure that:

Only authorized devices can connect to the organization's network.

User authentication mechanisms (such as multi-factor authentication) verify identities before granting access.

Devices with security vulnerabilities are flagged and restricted.

This aligns with IIA Standard 2110 – Governance, which emphasizes IT security controls for risk mitigation.

ISO 27001 and NIST Cybersecurity Framework also recommend device authentication and monitoring for secure network access.

Why Other Options Are Incorrect?

Option A (Limit personal use of employee devices):

Limiting personal use does not fully address network security risks; malware can still infect devices.

Option B (Control access through approvals and reviews):

While access control is important, it does not mitigate the broader risks of compromised devices connecting to the network.

Option D (Software scans and patch reminders):

Patching is important, but it does not prevent unauthorized access or ensure authentication for devices.

Implementing device detection and authentication controls is the most effective way to mitigate security risks in a BYOD environment.

IIA Standard 2110 and ISO 27001 emphasize strong network security measures.
