Why is SAS 70 Important to My Company?
By David G. Guenther, Alpern Rosenthal
Within many large private and public companies, one or more services
are outsourced which involve data which has a material financial impact.
Since it is unlikely that the contract with the outsourced service providers
contains a right to audit clause, alternative methods are used to validate
whether an adequate set of controls have been implemented and are effective
during the entire fiscal year.
SAS 70 reviews traditionally cover the applications controls which
support the operational processes an organization has outsourced and
the IT general controls as it relates to the environment in which the
applications operate within. Although the service auditor is required
to ensure that all controls are adequately represented by the service
organization within the limits of the defined scope, the competence
levels of these service auditors varies throughout the industry. Although
AICPA provides guidance on the various areas which should be included
in the application and IT general controls reviews, a checklist of the
specific controls are not provided and, therefore, reliance is placed
on the experience of the service auditor.
One of the most common questions when discussing SAS 70 reviews is
whether you can rely on the information provided. The most important
thing to understand is that the service organization (i.e., the organization
being reviewed) defines the scope of the audit and the control objectives.
The service auditor (i.e., the auditor which conducts the SAS 70 review)
is required to render an opinion as to whether the control objectives
are adequately represented based on the scope defined. However, the
service organization can exclude traditional areas of IT general controls
or application controls reviews and the service auditor is not required
to raise this as issue in their opinion. Therefore, the most critical
review that can be performed by the user organizations (i.e., organizations
that rely on the services provided by the service organization) and
the user auditors is to identify traditional areas which are not included
in the scope of the SAS 70 review.
The adequacy of the testing of the controls provided by the service
organization varies greatly within the industry. The type of test which
satisfies a SAS 70 requirement is quite different from what is required
for Sarbanes-Oxley (SOX). Collaborative inquiry is an acceptable form
of testing for SAS 70 reviews. Collaborative inquiry involves interviewing
two independent persons to validate that a control process is functioning
as intended. This type of testing does not involve any independent compliance
testing to validate that the control is functioning as intended. This
is known as a Type I report as it includes the service auditor’s
opinion on the fairness of the presentation of the service organization’s
description of controls that had been placed in operation and the suitability
of the design of the controls to achieve the specified control objective.
A Type II report includes the information contained in a Type I service
auditor’s report and also includes tests of the operating performance
as well as the service auditor’s opinion on whether controls were
operating effectively during the posted review. This report is in compliance
with the SOX requirements.
In addition, SAS 70 Type II reports are now placing more emphasis on
information technology’s role in the control environment of service
organizations. This helps to ensure that the SAS 70 report contains
all of the information required by user organization auditors. Type
II reports can be used by the user organization’s auditors to
assess internal control risk for the purposes of planning and executing
their financial audit.
With the introduction of SOX, SAS 70 has taken on an increased importance.
SOX adopted the COSO model of controls, which is the same model that
SAS 70 audits have utilized since inception. SOX heightened the focus
placed on understanding the controls over financial reporting. It identified
a Type II SAS 70 report as the only acceptable method of obtaining third-party
assurance regarding the controls at a service organization.
