IIA-CIA-Part3 Exam Dumps : Internal Audit Function

Understanding IT Infrastructure Risks and Workstation Security:

Reviewing an organization’s IT infrastructure risks includes assessing the security of workstations (desktops, laptops, and terminals) that connect to the organization's network.

Workstations are vulnerable to physical theft, unauthorized access, and malware attacks, making physical controls a critical security measure.

Why Physical Controls Are the Most Relevant for Workstations:

Physical controls prevent unauthorized physical access, theft, tampering, and damage to workstations.

Examples include:

Locked office spaces or workstation enclosures to restrict access.

Security badges or biometric authentication to prevent unauthorized use.

Cable locks for laptops and desktop computers to deter theft.

Surveillance cameras and security guards to monitor access.

Why Other Options Are Incorrect:

A. Input controls – Incorrect.

Input controls ensure accuracy and completeness of data entry, which applies more to application security, not workstation security.

B. Segregation of duties – Incorrect.

Segregation of duties prevents fraud and conflicts of interest, but it does not directly address workstation security risks.

D. Integrity controls – Incorrect.

Integrity controls ensure data consistency and accuracy in databases and transactions, not workstation security.

IIA’s Perspective on IT Risk and Physical Security Controls:

IIA Standard 2110 – Governance requires organizations to implement physical security measures for IT assets, including workstations.

IIA GTAG (Global Technology Audit Guide) on IT Risks highlights the importance of restricting physical access to IT devices to prevent unauthorized use or data breaches.

ISO 27001 Information Security Standard recommends physical controls to secure IT infrastructure and prevent workstation-related risks.

Thus, the correct and verified answer is C. Physical controls.

Authorization controls ensure that users have appropriate access levels based on their roles and responsibilities. The primary concern arises when all users have uniform access, as it violates the principle of least privilege (PoLP) and increases the risk of unauthorized access and data breaches.

(A) Users can only see certain screens in the system.

Incorrect. This is a good security practice, as it limits user access based on job roles, preventing unauthorized access to sensitive information.

(B) Users are making frequent password change requests.

Incorrect. Frequent password resets might indicate poor password management but are not directly related to authorization controls.

(C) Users input incorrect passwords and get denied system access.

Incorrect. This indicates authentication issues, not an authorization control concern. If users are denied access due to incorrect passwords, the system’s authentication mechanisms are working correctly.

(D) Users are all permitted uniform access to the system. ✅

Correct. Authorization should be role-based, meaning different users should have different levels of access depending on their responsibilities. Uniform access violates security best practices and increases the risk of fraud, data misuse, and compliance violations.

IIA GTAG "Identity and Access Management" emphasizes that authorization controls should be based on job functions to prevent unnecessary exposure to sensitive data.

IIA Standard 2120 – Risk Management highlights the importance of access control policies to mitigate cybersecurity risks.

Analysis of Answer Choices:IIA References:Thus, the correct answer is D, as uniform access across all users is a major security concern in authorization control.

According to the IIA Standards, follow-up is mandatory only for assurance engagements, where corrective action plans are agreed and tracked. Advisory services are intended to add value and offer recommendations but do not require formal follow-up by internal audit. Responsibility for implementing recommendations lies with management.

Options A and B improperly delegate follow-up responsibilities, and Option D incorrectly suggests mandatory follow-up for advisory engagements.
