CBA Information Technology Audits Questions and Answers 1 — Questions and Answers
Question 1: An IT auditor is reviewing a bank's change management process for its core banking system. Which of the following represents the MOST significant control weakness?
- Change requests are documented using a paper-based form before being entered into the tracking system.
- The same developer who codes a change is responsible for deploying it into the production environment. (Correct answer)
- End-user testing is performed in a dedicated test environment but not by the original requester.
- Emergency changes are verbally approved and documented retrospectively within five business days.
Correct answer: The same developer who codes a change is responsible for deploying it into the production environment.
The most significant weakness is the lack of segregation of duties. A developer having the ability to both write and deploy code to production creates a risk of unauthorized or untested changes, potentially leading to fraud, data integrity issues, or system failure. The other options, while not ideal, represent lesser risks. Paper forms are an inefficiency, not a critical control failure. Testing by someone other than the requester can be acceptable. Documenting emergency changes retrospectively is a common practice, provided the initial approval is timely and the process is well-controlled.
Question 2: A bank recently experienced a significant data center outage due to a natural disaster. The IT department successfully failed over to the disaster recovery (DR) site. When auditing the bank's Business Continuity Plan (BCP), which of the following is the MOST important audit procedure to perform?
- Reviewing the BCP documentation to ensure it includes contact information for key personnel.
- Verifying that the cost of the disaster recovery site is within the approved IT budget.
- Interviewing IT staff to confirm they received annual BCP awareness training.
- Assessing the adequacy of the Business Impact Analysis (BIA) to ensure the Recovery Time Objectives (RTOs) for critical systems were met. (Correct answer)
Correct answer: Assessing the adequacy of the Business Impact Analysis (BIA) to ensure the Recovery Time Objectives (RTOs) for critical systems were met.
The Business Impact Analysis (BIA) is the foundation of the Business Continuity Plan. It identifies critical business processes and sets the Recovery Time Objectives (RTOs)—the maximum tolerable downtime. The most crucial audit step is to verify if the bank's recovery performance during the actual disaster met these predefined objectives. If critical systems were not restored within their RTOs, the BCP was not effective, regardless of training, budget, or documentation details.
Question 3: During an audit of logical access controls for the bank's wire transfer system, which of the following conditions would be of GREATEST concern to a Certified Bank Auditor?
- A former employee's access was revoked two business days after their termination date.
- The system does not enforce a minimum password length of 12 characters.
- Shared, generic user accounts are used by the treasury department for end-of-day processing. (Correct answer)
- Access reviews are conducted semi-annually by department managers instead of quarterly.
Correct answer: Shared, generic user accounts are used by the treasury department for end-of-day processing.
The use of shared or generic accounts is the most significant concern because it eliminates individual accountability. If a fraudulent transaction occurs, it becomes impossible to trace the action to a specific person. This undermines non-repudiation and makes investigation extremely difficult. While delayed termination, weak password policies, and less frequent access reviews are all control weaknesses, the inability to hold individuals accountable for their actions poses a more severe and direct risk to the institution.
Question 4: An auditor is evaluating the controls over a bank's new customer-facing mobile application, which was developed by a third-party vendor. According to the FFIEC IT Examination Handbook, which of the following is a primary responsibility of the bank's management?
- Performing code-level security reviews of the vendor's software.
- Ensuring the vendor's disaster recovery plan is tested annually.
- Conducting a thorough risk assessment and due diligence process before and during the engagement. (Correct answer)
- Requiring the vendor to use the same brand of firewall as the bank for consistency.
Correct answer: Conducting a thorough risk assessment and due diligence process before and during the engagement.
The FFIEC places significant emphasis on third-party risk management. While the bank may not perform code reviews directly, it is ultimately responsible for the risks introduced by its vendors. A primary responsibility of the bank's management is to conduct comprehensive due diligence and ongoing risk assessments of its third-party service providers. This includes evaluating the vendor's security posture, financial stability, and operational controls to ensure they meet the bank's own risk appetite and regulatory requirements.
Question 5: A Certified Bank Auditor is planning an audit of the bank's cybersecurity incident response plan. Which audit test would BEST assess the plan's practical effectiveness?
- Confirming the plan has been reviewed and approved by the Board of Directors within the last year.
- Verifying that the plan includes an up-to-date contact list for all incident response team members.
- Reviewing the results and lessons learned from a recent tabletop exercise or simulation drill. (Correct answer)
- Ensuring the plan is stored in a secure, access-controlled location both on-site and off-site.
Correct answer: Reviewing the results and lessons learned from a recent tabletop exercise or simulation drill.
While plan approval, accurate contact lists, and secure storage are important compliance checks, the best way to assess the *effectiveness* of an incident response plan is to see how it performs in practice. Reviewing the outcomes of a tabletop exercise or a full simulation drill provides concrete evidence of the team's preparedness, identifies gaps in the plan, and demonstrates the bank's ability to respond to an actual incident.
Question 6: Which of the following activities is a key component of an IT governance framework within a financial institution?
- Daily reconciliation of nostro accounts.
- Performing penetration testing on external-facing applications.
- Ensuring that IT strategy is aligned with the bank's overall business strategy and objectives. (Correct answer)
- Installing and configuring antivirus software on all employee workstations.
Correct answer: Ensuring that IT strategy is aligned with the bank's overall business strategy and objectives.
IT governance is about ensuring that IT activities align with and support the business's overall goals. It involves leadership, organizational structures, and processes to ensure that the IT function sustains and extends the organization's strategies and objectives. While penetration testing and antivirus installation are important security operations, and reconciliation is a business process, the strategic alignment of IT with business objectives is the core purpose of IT governance.
