IIA-CIA-Part3 Exam Dumps - IIA CIA Questions and Answers

A systems development methodology refers to a structured approach used in software development and systems engineering to guide the design, development, and implementation of software applications.

Why Option A (Waterfall) is Correct:

Waterfall methodology is a linear and sequential systems development methodology where each phase (e.g., requirements, design, implementation, testing, deployment) must be completed before moving to the next.

It is widely established and historically one of the first software development methodologies.

Used in large-scale enterprise projects where detailed planning and structured execution are required.

Why Other Options Are Incorrect:

Option B (PRINCE2 - Projects in Controlled Environments):

Incorrect because PRINCE2 is a project management framework, not a systems development methodology.

Option C (ITIL - Information Technology Infrastructure Library):

Incorrect because ITIL is a set of IT service management (ITSM) best practices, not a software development methodology.

Option D (COBIT - Control Objectives for Information and Related Technologies):

Incorrect because COBIT is a governance framework for IT management and controls, not a development methodology.

IIA GTAG – "Auditing IT Projects and Systems Development": Highlights Waterfall as a traditional systems development methodology.

IIA’s Global Technology Audit Guide on IT Risks: Discusses software development lifecycle risks, including Waterfall methodology.

COBIT Framework – BAI03 (Manage Solutions Identification and Build): References structured methodologies like Waterfall in IT governance.

Comprehensive and Detailed In-Depth Explanation:

Authentication methods are categorized into three factors:

Something you know (e.g., passwords, PINs).

Something you have (e.g., ID cards, key fobs, smart cards).

Something you are (e.g., biometrics like fingerprints, retina scans).

Option C (A card-key scanner) aligns with "something you have", as it requires a physical token (card) for authentication.

Option A (Retina scan) and Option D (Fingerprint scanner) fall under biometric authentication ("something you are").

Option B (PIN code reader) is based on "something you know".

Thus, C is the correct answer because a card-key represents a physical access control mechanism based on possession.

A spear phishing attack is a targeted email attack aimed at a specific individual, organization, or business. Unlike general phishing, which casts a wide net, spear phishing is highly personalized and designed to deceive the recipient into providing sensitive information.

Personalization – The email references a golf membership renewal, making it relevant and believable to the recipient.

Social Engineering – The attacker exploits the victim’s trust by pretending to be a legitimate entity.

Malicious Link – The victim clicks a fraudulent hyperlink and enters sensitive credit card details.

Financial Fraud – The goal is to steal payment information, leading to unauthorized transactions.

A. Numerous and consistent attacks on the company’s website caused the server to crash.

This describes a Denial-of-Service (DoS) attack, not spear phishing.

B. A person posing as an IT help desk representative called employees and played a generic message requesting passwords.

This describes vishing (voice phishing) rather than spear phishing.

D. Many users of a social network service received fake notifications about a new investment opportunity.

This is general phishing, as it targets multiple users instead of one individual.

IIA’s GTAG (Global Technology Audit Guide) on Cybersecurity – Emphasizes the risk of spear phishing in cyber fraud.

NIST SP 800-61 (Computer Security Incident Handling Guide) – Defines spear phishing as a highly targeted attack method.

COBIT 2019 (Governance and Management of IT) – Highlights social engineering risks in IT security.

Why Option C is Correct?Why Not the Other Options?IIA References:✅ Final Answer: C. A person received a personalized email regarding a golf membership renewal, and he clicked a hyperlink to enter his credit card data into a fake website.

Data analysis in internal auditing allows auditors to assess large volumes of data, identify trends, and uncover anomalies, leading to a more comprehensive understanding of the audit area.

Definition and Role of Data Analysis in Auditing:

Data analytics in internal auditing involves using software and algorithms to analyze vast datasets for fraud detection, risk assessment, and control effectiveness.

The IIA’s GTAG on Continuous Auditing emphasizes that data-driven audits enhance visibility into operations, supporting risk-based auditing.

Why a More Holistic View?

Data analytics allows internal auditors to:

Identify patterns and trends across the entire audit area.

Detect fraud and anomalies more efficiently.

Assess risks across multiple departments simultaneously.

As per IIA Standard 1220 (Due Professional Care), auditors must consider the use of technology-based audit techniques to improve their audit scope.

Why Not Other Options?

A. It easily aligns with existing internal audit competencies to reduce expenses:

While data analytics can reduce costs, its primary benefit is enhanced audit scope and effectiveness, not just cost-cutting.

C. Its outcomes can be easily interpreted into audit conclusions:

Data analytics can enhance audit conclusions, but the interpretation still requires auditor expertise.

D. Its application increases internal auditors' adherence to the Standards:

While data analytics aligns with IIA Standards, it is not the main reason for its adoption.

IIA GTAG – Continuous Auditing: Implications for Assurance & Monitoring

IIA Standard 1220 – Due Professional Care

IIA Standard 2120 – Risk Management

Step-by-Step Justification:IIA References:Thus, the correct and verified answer is B. It provides a more holistic view of the audited area.
