From Bud Genovese, Managing Director

SOC 1 Summary of Changes from the SSAE 16 Standard to the SSAE 18 Standard

Services providers that store or process information for third parties should be able to provide an annual SOC (Service Organization Controls) report to customers when requested.  A SOC 1 report focuses on the controls over financial reporting. If the information handled by the service provider relates to financial statements, then a SOC 1 review and report should be completed. The SOC 1, SSAE 16 format was created originally under the SSAE 16 standard which replaced the SAS 70 standard.  Effective May 1, 2017, a SOC 1 report is now completed under the SSAE 18 AICPA attestation standard.  The standard requires that the SOC 1 report only note “SOC 1” and should not reference or use “SSAE 18” as part of the report or title. This advisory
presents the major changes that apply to SOC 1.

SOC 2 and SOC 3 reports are completed according to the AICPA Trust Service Principles. SOC 2 and SOC 3 reports are focused on the controls related to compliance and operation of the service provider. A SOC 2 or SOC 3 report provides documented assurances that operational safeguards are in place that relate to one, or all, of the following trust service principles: security, availability, processing integrity, confidentiality, or privacy. The following changes do not affect the SOC 2 and SOC 3 reports, as the SSAE 18 does not apply to them.

SSAE 18 Changes That Apply to SOC 1

Subservice Organizations:

SSAE 18 is requiring that service organizations implement processes that monitor the controls at subservice organizations. This new requirement requires service organizations to state the vendor management controls they have in place for subservice providers (for example, colocation facility).

Complementary Subservice Organization Controls:

The SSAE 18 introduces the concept of “Complementary Subservice Organization” controls which will be included in the service provider’s system description. This concept establishes and defines the controls for which customers must now assume in the design of the system description. This addition to the system description is similar to the Complementary User Entity Controls section.

Signed Written Assertion Requirement:

The written assertion is the statement found within the SOC report where the service organization asserts that the system description provided is true and complete. This statement has always been contained within the SOC 1 reporting document but the requirement that the service organization signs the document was optional. Like many firms, AuditOne, Inc. has already been requiring this section to be signed by service providers as a way to strengthen the credibility of the report.

Service Auditor Risk Understanding:

The SSAE 18 requires service auditors to obtain a more in-depth understanding of the development of the subject matter than currently required, in order to better identify the risks of material misstatement in an examination engagement. This enhancement should lead to an improved understanding between assessed risks and the nature, timing, and extent of attestation procedures performed in response to those risks.
