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

According to the IIA Standards, audit communications must be accurate, objective, clear, concise, constructive, and timely. In this case, the auditor’s statement that “controls are as effective as last year” is inaccurate, because the prior year’s report identified significant weaknesses. Equating ineffective controls with effectiveness misrepresents the actual condition, thereby compromising accuracy.

Objectivity (Option C), conciseness (Option A), and constructiveness (Option B) are not the main issue here. The primary weakness is accuracy (Option D).

Ransomware is a type of cyberattack where malicious software encrypts an organization ' s data, making it inaccessible until a ransom is paid to the attacker. This aligns with the question’s scenario, where denial-of-service is caused by malicious data encryption.

Let ' s analyze the options:

A. Phishing:

Phishing is a social engineering attack that tricks individuals into providing sensitive information, such as usernames, passwords, or credit card numbers. It does not involve encryption or direct denial-of-service.

B. Ransomware (✅ Correct Answer):

Ransomware encrypts critical data and demands a ransom for its release, effectively causing a denial-of-service scenario since the victim cannot access their own systems.

Some well-known ransomware attacks include WannaCry and NotPetya.

C. Hacking:

Hacking is a broad term for unauthorized access to systems but does not specifically refer to denial-of-service through encryption. Ransomware is a specific type of hacking attack.

D. Malware:

Malware (malicious software) is a general category that includes viruses, trojans, worms, spyware, and ransomware. While ransomware is a type of malware, not all malware encrypts data to demand ransom.

IIA Global Technology Audit Guide (GTAG) – Auditing Cybersecurity Risks – Discusses various cyber threats, including ransomware.

NIST Cybersecurity Framework (CSF) – Defines ransomware as a major threat that disrupts business continuity.

COBIT Framework (Control Objectives for Information and Related Technologies) – Addresses risks associated with ransomware and how internal auditors should assess controls.

ISO/IEC 27001 – Information Security Management Systems (ISMS) – Identifies the importance of cybersecurity measures to prevent ransomware attacks.

Matrix organizations do not usually minimize costs or simplify communication. They often increase communication complexity because employees may report to both functional and product, project, or geographic managers. This dual authority can create conflict, role ambiguity, slower decisions, and stress. However, matrix structures can provide flexibility by allowing resources and expertise to move across projects or product lines. Option A is true because functional and product managers may disagree over priorities. Option B is true because dual command can increase workplace stress. Option C is true because flexibility is a major benefit of matrix design. Internal audit should assess whether accountability, approval authority, and conflict resolution are clearly defined in matrix structures. Therefore, Option D is false.

Just-in-time inventory systems aim to minimize inventory levels by receiving materials close to the time they are needed in production or sale. Because inventory buffers are reduced, the organization has less room to absorb defects, delivery failures, or poor-quality inputs. Therefore, JIT systems rely heavily on high-quality materials, dependable suppliers, accurate demand information, and strong production scheduling. Option A is incorrect because JIT seeks to reduce safety stock, not depend on users determining large safety stock levels. Option B is wrong because JIT principles can be used by organizations of different sizes if supplier reliability and process discipline exist. Option C is overly negative and inaccurate; while JIT may affect supply chain inventory distribution, it can improve efficiency when properly managed. Therefore, Option D is correct.
