Audit Guidance Examination Procedures

Examination objectives allow the examiner to determine the quality and effectiveness of the audit function related to IT controls. These procedures will disclose the adequacy of audit coverage and to what extent, if any, the examiner may rely upon the procedures performed by the auditors in determining the scope of the IT examination.

• Tier I objectives and procedures relate to the institution’s implementation of an effective audit function that may be relied upon to identify and manage risks.
• Tier II objectives and procedures provide additional validation as warranted by risk to verify the effectiveness of the institution’s audit function. Tier II questions correspond to the Uniform Rating System for Information Technology (URSIT) rating areas and can be used to determine where the examiner may rely upon audit work in determining the scope of the IT examination for those areas.

Tier I Objectives and Procedures

Objective 1: Determine the scope and objectives of the examination of the IT audit function and coordinate with examiners reviewing other programs.

1. Review past reports for outstanding issues, previous problems, or high-risk areas with insufficient coverage related to IT. Consider:

• Regulatory reports of examination
• Internal and external audit reports, including correspondence/communication between the institution and auditors
• Regulatory, audit, and security reports from key service providers
• Audit information and summary packages submitted to the board or its audit committee
• Audit plans and scopes, including any external audit or internal audit outsourcing engagement letters
• Institution’s overall risk assessment

2. Review the most recent IT internal and external audit reports in order to determine:

• Management’s role in IT audit activities;
• Any significant changes in business strategy, activities, or technology that could affect the audit function;
• Any material changes in the audit program, scope, schedule, or staffing related to internal and external audit activities; and
• Any other internal or external factors that could affect the audit function.

3. Review management’s response to issues raised since the last examination. Consider:

• Adequacy and timing of corrective action
• Resolution of root causes rather than just specific issues
• Existence of any outstanding issues
  

4. Assess the quality of the IT audit function. Consider:

• Audit staff and IT qualifications
• IT audit policies, procedures, and processes
  

Using the results from the preceding procedures and discussions with the EIC, select from the following examination procedures those necessary to meet the examination objectives. Note: examinations do not necessarily require all steps.

Objective 2: Determine the quality of the oversight and support of the IT audit function provided by the board of directors and senior management.

1. Review board resolutions and audit charter to determine the authority and mission of the IT audit function.
2. Review and summarize the minutes of the board or audit committee for member attendance and supervision of IT audit activities.
3. Determine if the board reviews and approves IT policies, procedures, and processes.
4. Determine if the board approves audit plans and schedules, reviews actual performance of plans and schedules, and approves major deviations to the plan.
5. Determine if the content and timeliness of audit reports and issues presented to and reviewed by the board of directors or audit committee are appropriate.
6. Determine whether the internal audit manager and the external auditor report directly to the board or to an appropriate audit committee and, if warranted, has the opportunity to escalate issues to the board both through the normal audit committee process and through the more direct communication with outside directors.
   

Objective 3: Determine the credentials of the board of directors or its audit committee related to their ability to oversee the IT audit function.

1. Review credentials of board members related to abilities to provide adequate oversight. Examiners should:

• Determine if directors responsible for audit oversight have appropriate level of experience and knowledge of IT and related risks
• If directors are not qualified in relation to IT risks, determine if they bring in outside independent consultants to support their oversight efforts through education and training
  

2. Determine if the composition of the audit committee is appropriate considering entity type and complies with all applicable laws and regulations. Note – If the institution is a publicly traded company, this is a requirement of Sarbanes-Oxley. Additionally, this is a requirement of FDICIA for institutions with total assets greater than $500 million.

Objective 4: Determine the qualifications of the IT audit staff and its continued development through training and continuing education.

1. Determine if the IT audit staff is adequate in number and is technically competent to accomplish its mission. Consider:

• IT audit personnel qualifications and compare them to the job descriptions
• Whether staff competency is commensurate with the technology in use at the institution
• Trends in IT audit staffing to identify any negative trends in the adequacy of staffing
  

Objective 5: Determine the level of audit independence.

1. Determine if the reporting process for the IT audit is independent in fact and in appearance by reviewing the degree of control persons outside of the audit function have on what is reported to the board or audit committee.

2. Review the internal audit organization structure for independence and clarity of the reporting process. Determine whether independence is compromised by:

• The internal audit manager reporting functionally to a senior management official (i.e., CFO, controller, or similar officer);
• The internal audit manager’s compensation and performance appraisal being done by someone other than the board or audit committee; or
• Auditors responsible for operating a system of internal controls or actually performing operational duties or activities.
  

Note that it is recommended that the internal audit manager report directly to the audit committee functionally on audit issues and may also report to senior management for administrative matters.

Objective 6: Determine the existence of timely and formal follow-up and reporting on management’s resolution of identified IT problems or weaknesses.

1. Determine whether management takes appropriate and timely action on IT audit findings and recommendations and whether audit or management reports the action to the board of directors or its audit committee. Also, determine if IT audit reviews or tests management’s statements regarding the resolution of findings and recommendations.

2. Obtain a list of outstanding IT audit items and compare the list with audit reports to ascertain completeness.

3. Determine whether management sufficiently corrects the root causes of all significant deficiencies noted in the audit reports and, if not, determine why corrective action is not sufficient.

Objective 7: Determine the adequacy of the overall audit plan in providing appropriate coverage of IT risks.

1. Interview management and review examination information to identify changes to the institution’s risk profile that would affect the scope of the audit function.

Consider:

• Institution’s risk assessment
• Products or services delivered to either internal or external users
• Loss or addition of key personnel
• Technology service providers and software vendor listings
  

2. Review the institution’s IT audit standards manual and/or IT-related sections of the institution’s general audit manual.

• Audit schedules and audit cycles support the entire audit universe, are reasonable, and are being met
  

2. Determine whether the institution has appropriate standards and processes for risk-based auditing and internal risk assessments that:

• Include risk profiles identifying and defining the risk and control factors to assess and the risk management and control structures for each IT product, service, or function
• Describe the process for assessing and documenting risk and control factors and its application in the formulation of audit plans, resource allocations, audit scopes, and audit cycle frequency
  

Objective 9: Determine the adequacy of the scope, frequency, accuracy, and timeliness of IT-related audit reports.

1. Review a sample of the institution’s IT-related audit reports and work papers for specific audit ratings, completeness, and compliance with board and audit committee-approved standards.

2. Analyze the internal auditor’s evaluation of IT controls and compare it with any evaluations done by examiners.

3. Evaluate the scope of the auditor’s work as it relates to the institution’s size, the nature and extent of its activities, and the institution’s risk profile.

4. Determine if the work papers disclose that specific program steps, calculations, or other evidence support the procedures and conclusions set forth in the reports.

5. Determine through review of the audit reports and work papers if the auditors accurately identify and consistently report weaknesses and risks.

6. Determine if audit report content is:

• Timely
• Constructive
• Accurate
• Complete

• State that any information pertaining to the institution must be kept confidential.
• Specify the locations of internal audit reports and the related work papers.
• Specify the period of time that vendors must maintain the work papers. If work papers are in electronic format, contracts often call for vendors to maintain proprietary software that allows the institution and examiners access to electronic work papers during a specified period.
• State that outsourced internal audit services provided by the vendor are subject to regulatory review and that examiners will be granted full and timely access to the internal audit reports and related work papers and other materials prepared by the outsourcing vendor.
• Prescribe a process (arbitration, mediation, or other means) for resolving problems and for determining who bears the cost of consequential damages arising from errors, omissions and negligence.
• State that outsourcing vendors will not perform management functions, make management decisions, or act or appear to act in a capacity equivalent to that of a member of institution management or an employee and, if applicable, they are subject to professional or regulatory independence guidance.
  

3. Consider arranging a meeting with the IT audit vendor to discuss the vendor’s outsourcing internal audit program and determine the auditor’s qualifications.

9. If the audit vendor also performs the institution’s external audit or other consulting services, determine whether the institution and the vendor have discussed, determined, and documented that applicable statutory and regulatory independence standards are being met. Note – If the institution is a publicly traded company, this is a requirement of Sarbanes-Oxley. Additionally, this is a requirement of FDICIA for institutions with total assets greater than $500 million.

10. Determine whether an adequate contingency plan exists to reduce any lapse in audit coverage, particularly coverage of high-risk areas, in the event the outsourced audit relationship is terminated suddenly.

Objective 12: Determine the extent of external audit work related to IT controls.

1. Review engagement letters and discuss with senior management the external auditor’s involvement in assessing IT controls.
