IIA IIA-CIA-Part3 Questions Answers

Comprehensive and Detailed In-Depth Explanation:

Physical access controls are security measures designed to prevent unauthorized physical access to tangible IT resources, such as computer hardware, servers, and networking equipment. Examples include locks, security guards, and biometric access systems. In contrast, logical access controls protect access to software and data within the IT system, ensuring that only authorized users can interact with digital resources. These controls include mechanisms like user IDs, passwords, firewalls, and encryption. Option A accurately captures this distinction, whereas the other options either reverse the definitions or misclassify examples of physical and logical controls.

A firewall is a security control mechanism designed to prevent unauthorized access to or from a private network. It monitors and filters incoming and outgoing network traffic based on predefined security rules.

Definition of Control Types:

Preventive Control: Stops an undesirable event from occurring.

Detective Control: Identifies and records events after they have happened.

Corrective Control: Takes action to correct an issue after it has been detected.

Discretionary Control: Provides access control based on user discretion.

Why a Firewall is a Preventive Control:

Firewalls block unauthorized access to protect networks before a security breach can occur.

They enforce security policies in real-time, preventing cyber threats such as malware, intrusions, and unauthorized data access.

As per IIA GTAG (Global Technology Audit Guide) on Information Security, firewalls are categorized as preventive controls because they proactively mitigate threats before they materialize.

Why Not Other Options?

A. Corrective: Firewalls do not correct security breaches; they prevent them.

B. Detective: Firewalls do not just detect threats but actively block them.

D. Discretionary: Firewalls operate based on preset security rules rather than user discretion.

Step-by-Step Justification:IIA References:Thus, the correct and verified answer is C. Preventive.

The comparable uncontrolled price method compares the price charged in a controlled transaction with the price charged in a comparable transaction between independent parties. Its major limitation is finding a sufficiently comparable uncontrolled transaction. Differences in product quality, contract terms, geography, volume, timing, market conditions, risks, and functions can make comparison difficult. Option B may describe a general risk of transfer pricing systems but is not the common CUP limitation. Option C is incorrect because adjustments may be possible if differences can be reliably measured. Option D is wrong because CUP is usually a direct method for identifying an arm’s-length price. Internal auditors reviewing transfer pricing should assess comparability, documentation, assumptions, and regulatory compliance. Therefore, Option A is correct.
