CIA IIA-CIA-Part3 Updated Exam

The matching principle is a fundamental accounting concept that ensures that expenses are recorded in the same period as the revenues they help generate.

Why Option C (Expense recognition is tied to revenue recognition) is Correct:

The matching principle states that expenses should be recognized in the same period as the revenue they help generate to ensure accurate financial reporting.

This principle is applied in accrual accounting under GAAP and IFRS, ensuring that expenses and revenues are properly aligned.

Why Other Options Are Incorrect:

Option A (Revenues should be recognized when earned):

This describes the revenue recognition principle, not the matching principle.

Option B (Revenue recognition is matched with cash):

Incorrect because the matching principle applies to accrual accounting, not cash accounting. Revenue can be recognized before cash is received.

Option D (Expenses are recognized at each accounting period):

Incorrect because expenses are not necessarily recognized in every period; they are matched to revenue.

IIA Practice Guide – "Auditing Financial Reporting Controls": Discusses the importance of the matching principle.

GAAP & IFRS Accounting Standards: Define and require the application of the matching principle.

COSO Internal Control Framework: Emphasizes revenue-expense alignment for accurate financial reporting.

A false positive occurs when a system incorrectly identifies a legitimate item as a threat or an unwanted entity. In the case of a spam filter, a false positive happens when the filter mistakenly classifies a genuine email as spam, even though it is legitimate.

Option A: "The spam filter removed incoming communication that included certain keywords and domains."

This describes a general filtering mechanism but does not indicate a mistake. If the filter was correctly configured, it is not necessarily a false positive. (Incorrect)

Option B: "The spam filter deleted commercial ads automatically, as they were recognized as unwanted."

If the ads were indeed unwanted, this is a true positive, meaning the system worked correctly. (Incorrect)

Option C: "The spam filter routed to the 'junk' folder a newsletter that appeared to include links to fake websites."

If the newsletter contained suspicious links, the filter was functioning as designed. This is not necessarily an error. (Incorrect)

Option D: "The spam filter blocked a fitness club gift card that coworkers sent to an employee for her birthday."

This is a clear example of a false positive because the email was not spam or malicious, yet the filter mistakenly blocked it. (Correct Answer)

IIA GTAG (Global Technology Audit Guide) on Cybersecurity and IT Risks: Discusses false positives and negatives in automated security controls.

IIA’s "Auditing IT Security Controls" Report: Emphasizes the need for tuning security filters to reduce false positives.

COBIT 2019 – DSS05.07 (Manage Security Services): Highlights the importance of minimizing false positives to ensure business communication is not disrupted.

Analysis of Each Option:IIA References:Thus, the correct answer is D. The spam filter blocked a fitness club gift card that coworkers sent to an employee for her birthday.

Understanding Data Recovery and Security Risks:

Data must be protected, recoverable, and accessible when needed while maintaining security.

The best practice is to store encrypted backups offsite while keeping encryption keys separate but accessible.

Why Option D is Correct?

Storing encrypted data offsite (a few hours away) ensures protection against disasters (e.g., fire, cyberattacks, physical damage).

Keeping encryption keys at the organization ensures that recovery is quick and controlled without risking unauthorized access.

This aligns with the IIA's IT Audit Practices and ISO 27001 (Information Security Management), which emphasize separate storage of encrypted data and encryption keys for security and recoverability.

IIA Standard 2110 – Governance requires internal auditors to assess whether IT governance ensures the availability and security of critical data.

Why Other Options Are Incorrect?

Option A (Encrypted physical copies and keys stored together at the organization):

If both data and keys are in the same location, a disaster or breach would make recovery impossible.

Option B (Encrypted copies and keys stored in separate locations far away):

While secure, if encryption keys are stored too far, recovery could be delayed, impacting business continuity.

Option C (Encrypted usage reports in a cloud database):

This does not ensure full data recovery; it only provides logs and structure changes, not the actual data.

Storing encrypted data offsite while keeping encryption keys accessible onsite follows best IT security and disaster recovery practices.

IIA Standard 2110 supports evaluating IT governance, including data security and recovery controls.

COBIT Framework – Data Security & Recovery Controls

Preventive security controls proactively stop unauthorized access before it occurs. The most effective method is strict access management, where new or additional access rights require formal validation before being granted.

Prevents Unauthorized Entry – Ensures that only approved personnel have access to the power plant.

Implements Segregation of Duties (SoD) – Supervisors validate access requests, reducing insider threats.

Aligns with Least Privilege Principle – Employees get only the minimum access necessary for their role.

Prevents Security Risks Before They Happen – Unlike detective or corrective controls, this method stops unauthorized access before it occurs.

A. Offboarding procedure (monthly review) – This is a detective control, identifying issues after access is granted, not preventing them.

B. Smart lock anomaly scanning – Also detective, as it identifies suspicious behavior after access has been used.

D. Automatic notifications for after-hours entry – A corrective control, responding to potential violations instead of preventing them.

IIA’s GTAG on Identity and Access Management – Recommends pre-approval processes for sensitive locations.

ISO 27001 Annex A.9 (Access Control) – Requires role-based access management for critical infrastructures.

NIST SP 800-53 (Security and Privacy Controls for Federal Information Systems) – Defines supervisor approval as a key preventive measure.
