Assessing Information Technology
General Control Risk:
An Instructional Case

Carolyn Strand Norman, Mark D. Payne, and
Valaria P. Vendrzyk

ABSTRACT: Information Technology General Controls (ITGCs), a fundamental category
of internal controls, provide an overall foundation for reliance on any information pro-
duced by a system. Since the relation between ITGCs and the information produced
by an organization’s various application programs is indirect, understanding how ITGCs
interact and affect an auditor’s risk assessment is often challenging for students. This
case helps students assess overall ITGC risk within an organization’s information sys-
tems. Students identify specific strengths and weaknesses within five ITGC areas, pro-
vide a risk assessment for each area, and then evaluate an organization’s overall level
of ITGC risk within the context of an integrated audit.

Keywords: internal controls; general control; ITGC; risk assessment.

INTRODUCTION

T
he Sarbanes-Oxley Act (SOX 2002) and the Public Company Accounting Oversight
Board (PCAOB) Auditing Standard No. 5 (PCAOB 2007) require that the organi-
zation’s chief executive officer (CEO) and chief financial officer (CFO) include an

assessment of the operating effectiveness of their internal control structure over financial
reporting when issuing the annual report. External auditors must review management’s
internal control assessment as part of an annual integrated audit of an organization’s internal
controls over financial reporting. In short, accountants—external auditors, internal auditors,
and management accountants at all levels—are actively involved in helping their respective
organizations comply with SOX-related internal control requirements.

Because of the pervasiveness of IT in organizations, the information systems themselves
contain many internal controls. As a result, both internal and external auditors must develop
an understanding of the IT environment and its related processes and controls, including
the IT general controls (ITGCs), by performing risk assessment procedures. Although de-
ficiencies in ITGCs do not directly result in misstated financial statements or material

control weaknesses, they can indirectly cause or contribute to application control deficien-
cies (Center for Public Company Audit Firms 2004). Since the relation between ITGCs
and the information produced by an organization’s various application programs is indirect,
understanding how ITGCs interact and affect an auditor’s risk assessment is often chal-
lenging for students. Accordingly, our case offers accounting faculty an assignment or
project that is a ‘‘real world,’’ comprehensive supplement to textbook materials on the topic
of risk and ITGCs.

THE CASE
Several months ago, you started working at a large public accounting firm as an IT

staff auditor. You are currently working on your first assignment, an ITGC review of the
Foods Fantastic Company (FFC). FFC is a publicly traded, regional grocery store chain,
headquartered in Mason, Maryland, and includes 50 stores located in the mid-Atlantic area.
The centralized data center is in Mason. FFC relies on an integrated suite of application
programs that include state-of-the-art software to manage merchandise replenishment, store-
level sales forecasting, and point-of-sale data. For example, FFC relies on bar code scanners
and credit / debit card readers. To maintain its competitive edge in its market area, FFC
recently implemented a fingerprint bio-coding payment system in all of its stores. This new
systems implementation required that FFC change several of its general-ledger application
programs; in particular, those related to its cash receipts processing. FFC does not use any
outside service organizations to provide its IT services.

Sophie Ewing, the audit senior who heads up your team, decided that because of FFC’s
complex and sophisticated IT processing, an IT General Control (ITGC) review is man-
datory to meet SAS 109’s risk assessment procedures and SOX Section 404 Management
Assessment of Internal Controls requirements. You know that an ITGC review is very
important because ITGCs provide the foundation for reliance on any financial information
FCC’s systems produce. Your evaluation will affect the financial auditor in assessing the
risk of material misstatement in FFC’s financials, and consequently, the audit plan. At your
first team meeting, Sophie announced that your firm’s network security specialists would
review the technical issues related to FFC’s internal controls. They will evaluate FFC’s
operating systems, its telecommunications software, and its network configuration and
firewalls.

In preparation for the meeting, Sophie encouraged you to review the key provisions
included in SAS 109, SOX Section 404, applicable sections of PCAOB Auditing Standard
No. 5, and your firm’s internal guidance, which groups ITGCs into the following five areas:
IT management, systems development, data security, change management, and business
continuity planning (BCP).

IT Management

IT management’s key concepts include IT’s position within the organization, whether

IT goals are aligned with the organization’s strategic goals, the use of an IT steering com-
mittee, and whether the IT department’s structure promotes proper segregation of duties to
protect the organization’s assets. Your primary concerns are:

● Does FFC have an IT strategic plan?
● To whom does the Chief Information Officer (CIO) report?
● What key responsibility areas report to the CIO?
● Does FFC have an IT steering committee? Is so, who are the members?

Assessing Information Technology General Control Risk: An Instructional Case 65

Issues in Accounting Education, February 2009

Systems Development

The key concepts within systems development include the existence of a new systems

implementation methodology, project management, pre- and post-implementation reviews,
quality control, adequate testing, and demonstrated compliance with the selected imple-
mentation methodology. Based on this understanding, your team’s primary concerns are:

● Does FFC design, develop, and implement systems in a logical fashion?
● Does the organization consider internal controls as an integral part of systems design

or does it retrofit them after implementation?
● To what extent is FFC’s Internal Audit department involved in systems development

activities? Is it part of the project review team? Is it a voting member of the team?
● In particular, how well did FFC manage the development and implementation of its

new fingerprint bio-coding payment system?

Data

Security

The critical concepts within data security include adherence to an established infor-

mation security policy, access approval on a need-to-know basis, periodic rotation or change
of access controls, monitoring, exception reporting, and incident response. Data security
has both physical and logical aspects. On the physical side, data security includes physical
access and environmental controls over the data center computer room. On the logical side,
data security includes policies related to password configuration, change, and history re-
strictions. Logical security also includes prompt review, modification, or removal of access
due to personnel transfers, promotions, and terminations. Your team’s primary concerns are:

● How well does FFC control physical access to its data center computer room?
● Is FFC’s computer room adequately protected against environmental dangers, such as

fire?
● Does FFC control logical access to its information systems? In particular, how does it

control the logical access of terminated or transferred employees?
● Does FFC have a current IT security policy?
● Does FFC produce access violation reports?
● Do FFC IT personnel adhere to IT policy and follow IT procedures? For example, do

appropriate personnel review any access violation reports and take the prescribed
action?

Change Management

Change Management’s key concepts include documented change procedures, user au-

thorization and approval, separation of duties in implementing changes, management re-
view, quality control, and adequate testing. Your audit team’s primary concerns are:

● Does FFC have (and follow) formal change management procedures?
● In particular, did FFC follow these procedures when making any necessary changes to

its current application programs because of the new bio-coding payment system? For
example: Were the changes approved? Did the programmers adequately test the changes
before putting them into production? Did the application programmer(s) that made the
code changes, test the changes, and / or put them into production?

Business Continuity Planning

Key concepts of BCP are management’s expectations regarding a timely recovery of

processing capabilities, the existence of a written plan, the currency of the plan, offsite

storage of both the plan and data files, and testing of the plan. Your audit team’s main
concerns are:

● Does FFC have a written BCP plan? Is it current?
● When is the last time FFC tested its plan?
● Does FFC back up its software and data? How often? Where do they store the backups?
● Did FFC need to recover its systems using its backups during the past fiscal year?

Information Collected During the ITGC Review
Under Sophie Ewing’s direction, you and other members of the audit team worked

very diligently reviewing FFC’s policies and procedures, interviewing FFC client personnel,
and observing FFC’s various operations and procedures related to its ITGCs. First, your
team created an organization chart to document the FFC’s management structure (see Ex-
hibit 1).

Exhibit 2 reflects the information your team collected from interviews, observations,
and reviews of corroborating documentation related to FFC’s ITGCs.

Foods Fantastic Company

IT General Control (ITGC) Review Notes

Notes from meetings with the Chief Financial Officer (CFO):

● Foods Fantastic Company (FFC) implemented a new bio-coding payment system in all of its
stores this past fiscal year.

● FFC’s IT Executive Steering Committee develops IT policies and reviews the overall operations
of the IT department. The voting members of the committee are:

1. the Senior Vice President (SrVP) and Chief Information Officer (CIO)
2. the VP, Applications
3. the VP, Data Base Administration (DBA)
4. the VP, Operations
5. the VP, Information Security (IS)
6. the Executive Vice President and Chief Financial Officer (CFO)
7. the SrVP, Internal Audit

● The IT Executive Steering Committee revised FFC’s security policy in 2005. The policy addresses
all organizational security issues including IT.

● FFC has no documented business continuity or disaster recovery plan. Management believes such
a plan is cost-prohibitive for an organization of its size and FFC has never experienced any major
business disruption. In case of disaster, the data center manager would retrieve the most recent
backup tapes that are stored offsite. FFC would use these files to recover its systems.

Notes from meetings with the SrVP, Internal Audit:

● FFC’s Internal Audit Department is involved as a voting member of the project teams responsible
for design, development, and implementation of new projects. Internal audit performs post-
implementation reviews on all projects over $2 million.

● The new bio-coding payment system was 25 percent over its initial time budget and 40 percent
over its initial dollar budget.

Notes from meetings with the CIO:

● The VP, Applications is currently responsible for the DBA function. However, the CIO reviews
the logs that show the actions of the Application VP’s user ID.

● FFC has an IT strategic plan, which is consistent with its corporate strategic plan. The IT strategic
plan outlines the objectives and strategies that the information systems group will implement to
assist FFC in meeting its overall business objectives.

● FFC adopted Structured Systems Analysis and Design Methodology (SSADM), an industry-
recognized standard for systems development and project management. All projects (buy or build)
follow the applicable SSADM phases. The CIO periodically reviews each project’s required
budget-to-actual reconciliation.

● FFC’s security policy states that the VP, IS is to conduct a user audit on a quarterly basis. The
appropriate department manager reviews electronically submitted reports that list each user’s
profile, note changes on the reports, and return the reports to the VP, IS. The VP then makes the
appropriate modifications based on the returned reports. The VP maintains the reports, and initials
and dates the report after completing all modifications.

Notes from meetings with the VP, Human Resources:

● FFC is currently interviewing individuals to assume the DBA’s responsibilities and hopes to hire
someone within the next six to eight months.

● Aside from the security policy, management does not provide any formalized security awareness
programs related to data security.

● Each month, the Human Resources department forwards a Transfers and Terminations report to
the VP, IS.

EXHIBIT 2 (continued)

Notes from meetings with the VP, Applications:

● The VP, Applications assigns a project manager and develops an initial time and dollar budget
for each new development project.

● IT personnel adequately tested the new bio-coding payment system prior to its implementation.
This testing included integration testing, stress testing, and user acceptance testing. User depart-
ments corroborated their testing and acceptance of the new system.

● Application programmers do not have access to the computer room unless escorted by data center
personnel (e.g., an operator).

● FFC instituted formal procedures for change management. The VP, Applications is responsible
for change management and maintains all documentation in a fireproof vault in his office. A
Change Request form initiates all application software changes, including required software up-
grades. A user completes the form, which the user’s department manager approves. The user
forwards the request form to the VP, Applications, who logs each request in a Change Request
Log. The VP performs an initial analysis and feasibility study and estimates the required devel-
opment hours. The Change Request log is a listing of all requested changes and the status of the
change request. The VP, Applications uses this log to track open items and follow up on changes
not completed within the original time estimate.

● The VP, Applications assigns the change request to an applications programmer and issues the
current system’s documention to the programmer. The applications programmer copies the source
code from the system’s production region to its development region and makes the change. The pro-
grammer works in the systems development region using test data. The programmer tests the
change first within the affected module and then within the entire application. Changes are never
tested against production data. The programmer updates the necessary system’s documentation.

● The applications programmer migrates the code to the system’s test region. A second programmer
performs systems integration testing, volume testing, and user acceptance testing, again using test
files. The second programmer then performs a quality review of the change, including a source-
compare analysis, and reviews the updated systems documentation.

● Upon completion of testing, the user who requested the change and the appropriate department
manager review the test results and accept the change by signing the original request form. The
VP, Applications reviews the user-approved request form on which the department manager has
indicated that s / he is satisfied that the program is ready for implementation. The VP, Applications
also reviews the documentation prior to implementing any new or changed program to ensure
that the documentation is adequate.

● The VP, Applications approves the change, initials the change request form, and transfers the
change to the VP, Operations, who officially accepts the change. The VP, Applications then
updates the Change Request log and returns the revised systems documentation to the fireproof
vault.

Notes from meetings with the VP, Operations:

● FFC’s computer room, within its data center, is locked at all times. All outside contractors or
visitors must first contact the data center manager for entry into the computer room. Each must
bring an official picture ID, sign a visitors’ log, and be escorted at all times by data center
personnel during the visit.

● In 2002, FFC installed video cameras on all doors entering the computer room to record activity
24 / 7. Building management staff, who report to the facilities manager, are responsible for main-
taining these tapes. The VP, Operations has not needed to review these tapes for at least six
months since no unathorized access attempts have been reported.

● Environmental controls are in place in the computer room (i.e., temperature controls, uninter-
rupted power supply, a backup generator, fire-extinguishing equipment, and raised floor). Appro-
priate maintenance staff test these controls semi-annually.

● FFC backs up all of its data each day. It stores its most recent daily backup once a week at a
company-owned offsite location, along with the most recent version of its software. FFC did not
test backup tapes during the past year and has no plan to test these tapes in the future.

● The VP, Operations assigns IT operations personnel the task of placing new or changed appli-
cations programs into production after the VP, Applications has approved the work.

EXHIBIT 2 (continued)

Notes from meetings with the VP, Information Security:

● The VP, IS grants keycard access to the computer room. The VP, IS receives a keycard access
report for the computer room on a monthly basis. The VP, IS determines if an unauthorized
access attempt into the computer room has occurred.

● Passwords are not displayed on terminals or reports. Password standards are enforced by security
software. FFC requires a minimum password length of six alphanumeric or special characters
and a maximum length of nine alphanumeric or special characters. The software prevents the
same character from being used more than once in a password and prevents numbers from being
used next to each other in a password. The security software forces users to change their pass-
words twice each year. The security software maintains a history of two previous passwords and
does not permit employees to reuse their two most recent passwords. The security software does
not display statistics regarding employees’ sign-on information. For example, there is no infor-
mation regarding a user’s sign-on attempts (such as date and time of last sign-on), number of
invalid sign-on attempts since last successful sign-on, or number of days prior to password
expiration.

● The system allows three access attempts. If the third attempt is unsuccessful, the user ID is
automatically disabled. The user must contact the VP, IS to reset the user ID. The system gen-
erates a logical access violation report on a daily basis.

● User access is limited to workstations within the corresponding responsibility area. For example,
users with access to the Accounts Payable module can only log in from workstations located in
the Accounts Payable area. A workstation can stand idle for up to 60 minutes before the user is
logged off.

● The VP, IS is responsible for maintaining user profiles and authorization lists.
● The VP grants access to the system to new hires. The appropriate department manager completes

a computerized form that specifies the proper level of access. The VP reviews the request form
for proper approvals and then either approves or denies the request. If approved, the VP issues
the necessary ID and initial password with the requested access via encrypted email.

● Normal users may have multiple IDs. Each user ID can log on to one sign-on session at a time.
The VP, IS, who has unlimited access, can log in from any workstation and have multiple sign-
on sessions.

● The VP, IS is responsible for modifying and / or disabling user IDs for personnel whose job duties
change because of promotions, transfers, and / or terminations based on the Transfers and Ter-
minations report. The VP, IS maintains the report, and initials and dates the report when the VP,
IS has made all of the modifications.

Notes from meeting with the facilities manager, who reports to the VP, Human Resources:

● According to the facilities manager, no one asked to view the computer room video tapes during
the past six months.

Observations of the audit team:

● Documentation of the systems development process for the new bio-coding payment system
confirms that the VP, Applications complied with SSADM requirements when implementing this
new system.

● The data center is on the first floor of FFC’s building. The data center manager reports to the
VP, Operations.

● Company policy requires the VP, IS to review the keycard access report at least once per quarter.
During the past six months, the VP has not reviewed the report for any unauthorized access
attempts.

● The team observed no instances in which application programmers were in the computer room
without a proper escort.

● The team observed no instances in which visitors or outside contractors were in the computer
room without a proper escort.

EXHIBIT 2 (continued)

● Documentation of the computer room environment controls test results for the last 18 months
shows no irregularities. These files are in the CIO’s office.

● If someone attempts to enter the computer room without authorization, company policy requires
that the VP, Operations review the video tapes from the computer room cameras within 24 hours.

● The FFC security policy requires each employee to sign an acknowledgment that s / he read the
current policy. A review of the personnel files of a sample of employees found no exceptions.

● A review of the selected user profiles and passwords revealed the following:

User Password
Vice President, Applications 7LiAcOf#
Vice President, Information Systems QSECOFR1

Note: The acronym QSECOFR looks familiar. Remember to review A Beginner’s Guide to Auditing the AS / 400
Operating System (Bines 2002).

● During the past six months, the dates of the modifications were about three weeks after the VP,
IS received the HR’s Transfers and Terminations report.

● The VP, IS performed the most recent user audit eight months ago.
● Company policy requires the VP, IS to review the unauthorized system access report on a monthly

basis to check for unusual activity (e.g., multiple violations, changes to the authorization lists,
etc.). During the past six months, the VP, IS has not reviewed the report for any unauthorized
access attempts.

● The audit team verified that FFC followed its approved change management procedures when
making the bio-code payment-related changes to its cash receipts processing and other financial
reporting application programs.

● In the past fiscal year, no incidents occurred that required FFC to recover its systems using its
backup tapes.

Case Requirements
Sophie Ewing assigned your team the following tasks:

1. For each ITGC area, identify the control issues and classify them as strengths or weak-
nesses, using Exhibit 3 to document your work. Exhibit 3 will be part of the audit
team’s work papers.

2. Determine the level of risk (High, Medium, or Low) that you believe is present in each
particular ITGC area.

3. Assess the overall risk of the organization’s ITGCs, taking into consideration the five
separate risk assessments that you just made (task #2 above), and their relative impor-
tance to internal controls over FFC’s financial reporting.
