System and Organization Controls (SOC) 1 Type 2
SOC 1 Type 2 overview
System and Organization Controls (SOC) for Service Organizations are internal control reports created by the American Institute of Certified Public Accountants (AICPA). They're intended to examine services provided by a service organization so that end users can assess and address the risk associated with an outsourced service.
A SOC 1 Type 2 attestation is performed under:
- SSAE No. 18, Attestation Standards: Clarification and Recodification, which includes AT-C section 320, Reporting on an Examination of Controls at a Service Organization Relevant to User Entities' Internal Control Over Financial Reporting (AICPA, Professional Standards).
- SOC 1 Reporting on an Examination of Controls at a Service Organization Relevant to User Entities’ Internal Control Over Financial Reporting (AICPA Guide).
The SOC 1 attestation has replaced SAS 70, and it is appropriate for reporting on controls at a service organization relevant to user entities internal controls over financial reporting. A Type 2 report includes auditor’s opinion on the control effectiveness to achieve the related control objectives during the specified monitoring period.
