An Intranet is a private network that is accessible only to an organization’s personnel. It is used for internal communication, data sharing, and collaboration while ensuring security and restricted access.

Let’s analyze each option:

Option A: An extranet

Incorrect. An extranet extends an organization’s internal network to external parties such as vendors, suppliers, or business partners. Since the organization wants to allow access only to its personnel, an extranet is not the right choice.

Option B: A local area network (LAN)

Incorrect. While a LAN is a network within a limited geographic area (such as an office), it does not necessarily restrict access only to personnel. Additionally, an intranet operates over a LAN but includes access controls and authentication mechanisms.

Option C: An Intranet

Correct. An intranet is specifically designed for internal use, allowing employees to securely share documents, collaborate, and access internal resources. Organizations can implement access control mechanisms to restrict access to authorized personnel only.

IIA Reference: Internal auditors assess IT security to ensure that internal networks (such as intranets) have appropriate access restrictions to protect sensitive data. (IIA GTAG: Auditing IT Networks)

Option D: The internet

Incorrect. The internet is a public network that does not restrict access. Using the internet for internal communication would expose sensitive data to external threats.

Thus, the verified answer is C. An Intranet.

The cash payback technique determines the time required to recover the initial capital investment from annual cash inflows. It is one of the simplest capital budgeting methods, focusing on liquidity and risk reduction.

The payback period helps management assess the risk of investment decisions.

Shorter payback periods indicate faster capital recovery, which is desirable for risk-averse firms.

The IIA’s Practice Guide: Financial Decision-Making supports the use of payback analysis for assessing capital investments.

B. Annual rate of return technique → Incorrect. This method calculates the percentage return on an investment but does not measure how long it takes to recover the investment.

C. Internal rate of return (IRR) method → Incorrect. IRR determines the discount rate at which the investment's net present value (NPV) is zero, but it does not calculate the payback period.

D. Net present value (NPV) method → Incorrect. NPV considers the time value of money but focuses on overall profitability, not the time required to recover initial investment.

IIA’s Global Internal Audit Standards on Capital Budgeting and Investment Analysis recommend payback period analysis for investment risk assessment.

IIA Standard 2130 – Control Self-Assessment highlights financial viability and risk analysis in investment decision-making.

COSO Enterprise Risk Management (ERM) Framework supports the use of the payback method for risk mitigation in capital projects.

Why Option A is Correct?Explanation of the Other Options:IIA References & Best Practices:Thus, the correct answer is A. Cash payback technique.

Automated attacks that attempt to exploit weak or leaked passwords—such as credential stuffing, brute force attacks, and dictionary attacks—pose a significant cybersecurity risk. Implementing two-step verification (also known as multi-factor authentication, or MFA) is one of the most effective measures to mitigate these threats.

Why Two-Step Verification is Effective (B - Correct Answer)

Multi-factor authentication (MFA) adds an additional security layer beyond a password, requiring a second factor such as a one-time code sent to a mobile device, biometric authentication, or a security key.

Even if an attacker obtains a password, they cannot access the account without the second authentication factor.

The IIA Global Technology Audit Guide (GTAG) 1: Information Security Management emphasizes the use of multi-factor authentication to prevent unauthorized access.

Why Other Options Are Less Effective:

Option A: Changing passwords every two years

Ineffective because attackers often use compromised credentials that may be recent. Best practices recommend regular password updates but coupled with MFA.

The IIA's GTAG 16: Identity and Access Management highlights that password rotation alone does not fully protect against automated attacks.

Option C: Using a VPN when out of the office

Irrelevant to password attacks. A VPN encrypts data and secures network connections but does not prevent brute force or credential stuffing attacks.

The IIA GTAG 17: Auditing Network Security discusses VPNs for secure remote access but does not consider them a solution for password-based attacks.

Option D: Using antivirus and security tools

While important for overall security, these tools cannot prevent attacks that exploit stolen or weak passwords.

The IIA GTAG 15: Information Security Governance states that security tools should be combined with authentication controls like MFA for best protection.

GTAG 1: Information Security Management – Recommends multi-factor authentication to prevent unauthorized system access.

GTAG 16: Identity and Access Management – Highlights the limitations of password-only security and supports multi-factor authentication.

GTAG 17: Auditing Network Security – Covers VPN usage but does not consider it a solution for password attacks.

GTAG 15: Information Security Governance – Discusses the role of security tools and authentication in securing user accounts.

Step-by-Step Explanation:IIA References for Validation:Thus, requiring two-step verification (B) is the most effective control against automated password attacks.
