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.

To enable management to receive timely feedback and mitigate unforeseen risks, it is critical to have a performance measurement system in place. Measuring product performance against an established standard is a key control mechanism that allows management to identify deviations, take corrective actions, and mitigate risks proactively.

Performance Monitoring & Timely Feedback: Comparing actual product performance against set standards helps in detecting quality issues, inefficiencies, or process failures early.

Risk Mitigation: Ensures that any deviations from expected performance can be addressed before they become major problems.

Internal Control Best Practices: Measuring against standards aligns with IIA’s risk management principles to ensure continuous monitoring and improvement.

Option B (Develop standard methods for performing established activities): While standardization improves efficiency, it does not provide ongoing feedback or mitigate unforeseen risks in real-time.

Option C (Require the grouping of activities under a single manager): Centralizing activities may improve coordination, but it does not directly provide timely performance feedback.

Option D (Assign each employee a reasonable workload): Managing workloads ensures efficiency but does not provide risk mitigation through performance monitoring.

IIA’s Standard 2120 – Risk Management: Requires internal auditors to assess whether an organization’s risk management processes enable timely risk identification and mitigation.

COSO’s Internal Control Framework (Performance Monitoring Component): Emphasizes measuring actual performance against expected outcomes as a fundamental internal control.

Why Option A is Correct:Why Other Options Are Incorrect:IIA References:Thus, the most appropriate answer is A. Measure product performance against an established standard.

Planning (ERP) software implementation, to evaluate whether the organization is prepared for the change. This type of audit helps identify potential risks, resource availability, process gaps, and stakeholder alignment, which are critical for successful implementation.

A. Readiness assessment (Correct Answer) – This assessment evaluates if the organization has the necessary resources, technology, and processes in place for a successful ERP implementation.

B. Project risk assessment – While a project risk assessment identifies potential threats to project success, it does not provide an overall assurance on readiness before implementation.

C. Post-implementation review – This is conducted after the project is completed and does not help assess the likelihood of success before implementation.

D. Key phase review – This approach evaluates progress during implementation but does not provide enterprise-wide assurance before starting the project.

IIA GTAG 12 – Auditing IT Projects recommends a readiness assessment before launching major IT initiatives.

IIA IPPF Standard 2120 – Risk Management emphasizes identifying pre-implementation risks to improve project success.

COBIT 2019 – APO03 (Managed Enterprise Architecture) supports readiness evaluations before system rollouts.

Key Performance Indicators (KPIs) are used to measure and monitor the effectiveness of a process within an organization. In this case, the internal auditor found that 3% of payments did not match submitted invoices, which indicates a potential control weakness in the accounts payable process.

Process Owner’s Tolerance for Performance Deviations (Correct Answer: A)

The most relevant KPI would be one that sets acceptable error limits for invoice payments.

IIA Standard 2120 – Risk Management states that auditors should assess management's risk tolerance and evaluate whether processes are operating within acceptable limits.

If the organization's threshold for errors is 1% and the audit found 3%, it indicates a significant issue requiring corrective action.

This KPI helps the auditor assess materiality and determine the significance of the 3% deviation.

Why the Other Options Are Incorrect:

B. KPI defining the importance of performance levels and disbursement statistics (Incorrect)

While understanding performance levels and disbursement statistics is useful, this KPI does not directly address error tolerance or the impact of deviations.

C. KPI defining timeliness of reporting disbursement errors (Incorrect)

Reporting errors quickly is important, but this KPI does not help in determining whether a 3% error rate is acceptable or excessive.

D. KPI defining operating ratio objectives (Incorrect)

Operating ratio objectives focus on financial efficiency rather than error tolerance or accuracy in invoice processing.

IIA Standard 2120 – Risk Management (Assessing risk tolerance in financial processes)

IIA Standard 2210 – Engagement Objectives (Evaluating process performance against defined thresholds)

IIA Standard 2130 – Compliance (Ensuring adherence to financial control policies)

Step-by-Step Justification:IIA References for This Answer:Thus, the best answer is A. A KPI that defines the process owner's tolerance for performance deviations, as it directly helps the auditor assess the materiality of the 3% error rate in accounts payable.

Big data refers to extremely large and complex datasets that require advanced analytics to extract insights. Effective visualization is a crucial step in making big data analytics actionable.

Let’s analyze the options:

A. Big data is often structured.

Incorrect. Big data can be structured, semi-structured, or unstructured. Many sources of big data (e.g., social media, sensor data, emails) are unstructured, making analysis more challenging.

B. Big data analytic results often need to be visualized. ✅ (Correct Answer)

Correct. Due to its complexity, big data analytics results must often be visualized using dashboards, charts, or graphs to communicate insights effectively.

Examples of visualization tools include Tableau, Power BI, and Google Data Studio.

C. Big data is often generated slowly and is highly variable.

Incorrect. Big data is typically generated rapidly and continuously (e.g., social media posts, IoT sensors, financial transactions). This relates to the "velocity" characteristic of big data.

D. Big data comes from internal sources kept in data warehouses.

Incorrect. Big data comes from both internal and external sources, including social media, cloud applications, and sensors. Additionally, data warehouses store structured data, whereas big data is often unstructured and stored in data lakes.

A hot site is a fully operational, ready-to-use backup site that allows an organization to quickly resume business operations after a disaster. For an Internet Service Provider (ISP), maintaining continuous operations is critical, and a hot site ensures minimal downtime by providing pre-configured hardware, software, and network connectivity.

A. On-site – Keeping backups and disaster recovery infrastructure on-site is risky because it can be affected by the same disaster that damaged the primary servers.

B. Cold site – A cold site is a backup location that has infrastructure but lacks pre-installed systems and configurations. It takes significant time to become operational, making it unsuitable for an ISP needing quick recovery.

C. Hot site (Correct Answer) – A hot site is fully operational, with replicated data, applications, and network configurations that allow an ISP to quickly switch operations, minimizing service disruption.

D. Warm site – A warm site is partially equipped with some hardware and software but requires configuration before becoming operational. This delays recovery compared to a hot site.

IIA GTAG (Global Technology Audit Guide) 10 – Business Continuity Management emphasizes the importance of hot sites for organizations requiring real-time service restoration.

IIA IPPF Standard 2120 – Risk Management advises organizations to assess disaster recovery plans and ensure continuity strategies align with business needs.

Comprehensive and Detailed In-Depth Explanation:

System software controls are mechanisms designed to protect system integrity, security, and performance. Among the given options, performing intrusion testing on a regular basis (D) is a proactive security measure that tests an organization's IT infrastructure to identify vulnerabilities and weaknesses in system security.

Option A (Restricting server room access) is a physical security control, not a system software control.

Option B (Housing servers securely) is an environmental control, focusing on protecting hardware.

Option C (Ensuring documentation of user requirements) relates to project management and system development, rather than system software security.

Since intrusion testing ensures system resilience against cyber threats, option D is the correct answer.

Comprehensive and Detailed In-Depth Explanation:

Authentication ensures that only authorized users can access a system by requiring credentials such as PINs, passwords, or biometrics.

Option A (Remote wipe) – Deletes data but does not control initial access.

Option B (Software encryption) – Protects stored data, not user access.

Option C (Device encryption) – Secures the device, but authentication controls access.

Since authentication ensures secure user verification, Option D is correct.
