Pearson IIA-CIA-Part3 New Attempt

Understanding the Three Lines of Defense Model:

First Line of Defense (Operational Management): Performs daily IT security tasks, such as blocking unauthorized traffic and encrypting data.

Second Line of Defense (Risk Management & Compliance): Monitors and reviews security controls, including disaster recovery testing and risk management activities.

Third Line of Defense (Internal Audit): Provides an independent assessment of IT security controls.

Why Option C (Review Disaster Recovery Test Results) Is Correct?

The second line of defense is responsible for monitoring and evaluating IT risk management processes, including disaster recovery and business continuity planning.

Reviewing disaster recovery test results ensures that the organization is prepared for IT disruptions and meets compliance requirements.

IIA Standard 2110 – Governance requires auditors to evaluate whether IT risk management activities (such as disaster recovery) are being effectively monitored.

Why Other Options Are Incorrect?

Option A (Block unauthorized traffic):

This is a first-line defense task, typically handled by IT security teams (e.g., firewall and intrusion detection system monitoring).

Option B (Encrypt data):

Encryption is part of daily IT security operations and is handled by the first line of defense.

Option D (Provide an independent assessment of IT security):

Independent assessments are the responsibility of internal audit (third line of defense), not the second line.

The second line of defense focuses on monitoring IT risk, making disaster recovery test review a key responsibility.

IIA Standard 2110 and the Three Lines of Defense Model confirm this role.

Understanding BYOD Risks and Legal Implications

Bring-your-own-device (BYOD) policies allow employees to use personal devices for work, but they introduce compliance risks.

Jailbreaking is the process of bypassing manufacturer-imposed security restrictions on a device (e.g., iPhones or Android devices).

This significantly increases the risk of privacy law violations, copyright infringements, and security breaches.

Why Option D is Correct?

Jailbreaking allows users to:

Install unauthorized software, which may violate software licensing agreements and copyright laws.

Remove security restrictions, increasing exposure to data breaches, malware, and non-compliance with privacy regulations (e.g., GDPR, HIPAA, or CCPA).

Bypass digital rights management (DRM), leading to potential copyright infringement issues.

IIA Standard 2110 – Governance mandates that internal auditors evaluate IT risks, including legal compliance related to mobile device usage.

ISO 27001 – Information Security Management also highlights the risks of unapproved software on enterprise devices.

Why Other Options Are Incorrect?

Option A (Not installing anti-malware software):

While a security risk, this primarily exposes devices to cyber threats rather than directly causing regulatory infringements.

Option B (Updating operating software in a haphazard manner):

Irregular updates pose security risks, but they do not directly violate copyright or privacy laws.

Option C (Applying a weak password):

Weak passwords increase security risks, but they do not inherently cause regulatory infringements like jailbreaking does.

Jailbreaking increases risks of copyright infringement (through unauthorized apps) and privacy violations (by removing security controls).

IIA Standard 2110 and ISO 27001 emphasize legal and regulatory compliance in IT security audits.

Understanding Management by Objectives (MBO):

MBO is a performance management approach where employees set clear, measurable goals aligned with organizational objectives.

Success depends on employee participation in goal-setting to increase motivation, commitment, and performance.

Why MBO Works Best with Employee Involvement:

Engagement and Accountability: Employees are more motivated and accountable when they help define their goals.

Alignment with Organizational Strategy: Ensures that goals at all levels support the company’s broader objectives.

Improved Communication: Encourages collaboration between management and employees, leading to better alignment of expectations.

Why Other Options Are Incorrect:

A. It is particularly helpful to management when the organization is facing rapid change:

MBO is not well-suited for rapidly changing environments, as predefined goals may become irrelevant quickly.

B. It is more successful when adopted by mechanistic organizations:

Mechanistic organizations (rigid structures, strict hierarchies) often struggle with MBO because it requires flexibility and employee participation.

D. It is particularly successful in environments that are prone to having poor employer-employee relations:

While MBO can improve communication, it is not a solution for poor employer-employee relations, as trust and collaboration are essential for its success.

IIA’s Perspective on Performance Management and Organizational Success:

IIA Standard 2120 – Risk Management emphasizes the need for effective goal-setting and employee involvement in performance assessment.

Balanced Scorecard Framework supports MBO principles by aligning employee performance with strategic objectives.

COSO ERM Framework highlights the importance of employee engagement in goal-setting to enhance decision-making and risk management.

Balanced Scorecard Approach – Employee Participation in Goal Setting

Thus, the correct and verified answer is C. It is more successful when goal setting is performed not only by management, but by all team members, including lower-level staff.

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.
