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

The described situation is a classic social engineering attack, specifically a phishing or CEO fraud (business email compromise) attempt. Social engineering exploits human psychology rather than technical vulnerabilities. In this case, the attacker attempted to impersonate the CEO and trick the board member into making an unauthorized payment.

(A) Incorrect – A risk of spyware and malware.

Spyware and malware typically involve malicious software installed on a device, which is not the case here.

This attack relied on deception rather than malware to obtain unauthorized funds.

(B) Incorrect – A risk of corporate espionage.

Corporate espionage involves unauthorized data theft, sabotage, or insider threats.

The attacker here attempted financial fraud, not intellectual property theft.

(C) Incorrect – A ransomware attack risk.

Ransomware encrypts files and demands payment for decryption.

There is no mention of system encryption or ransom demands in this case.

(D) Correct – A social engineering risk.

The attacker impersonated the CEO and used urgency to manipulate the board member into processing a fraudulent payment.

This technique is a business email compromise (BEC) scam, a well-known social engineering tactic.

IIA’s GTAG (Global Technology Audit Guide) – Cybersecurity Risks and Controls

Discusses social engineering and its impact on financial fraud.

NIST Cybersecurity Framework – Social Engineering Threats

Defines social engineering tactics, including email impersonation and phishing.

COBIT Framework – Information Security Governance

Recommends controls to mitigate social engineering risks, such as employee training and email authentication mechanisms.

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

A data dictionary stores metadata about a database, including definitions, structure, tables, fields, relationships, formats, constraints, and sometimes configuration-related information about database objects. It helps users, developers, administrators, and auditors understand what data exist, how they are organized, and how they should be interpreted. A database table stores actual data records, not the overall metadata repository. Program files contain application or system logic. A backup system stores copies of data for recovery, not the definitions and metadata of the database. Internal auditors use data dictionaries when validating data extracts, performing analytics, reviewing system interfaces, and assessing data governance. Because it stores metadata about database objects and structure, Option D is correct.

Unauthorized external changes to data are best prevented through layered preventive controls. A firewall restricts unauthorized network access from external sources. Antivirus software helps prevent malicious code from modifying or corrupting data. Data encryption protects data confidentiality and can reduce unauthorized use or alteration when combined with proper key controls. Backup procedures are important recovery controls, but they do not prevent unauthorized changes from occurring. Change logs are detective controls because they record activity after changes occur. Internal auditors evaluating data protection should distinguish preventive, detective, and corrective controls. The best preventive combination listed is antivirus software, firewall, and encryption. Therefore, Option A is correct.
