A SOC audit, or System and Organization Controls audit, is an examination of a service organization's controls and processes relating to the security, availability, processing integrity, confidentiality, and privacy of the data it processes on behalf of its customers. There are three types of SOC reports – SOC 1, SOC 2, and SOC 3. SOC 1 reports are focused on internal controls over financial reporting, while SOC 2 and SOC 3 reports are broader in scope, covering security, availability, processing integrity, confidentiality, and privacy.
SOC 1 audits are conducted in accordance with the Statement on Standards for Attestation Engagements (SSAE) No. 18, which is issued by the Auditing Standards Board of the American Institute of Certified Public Accountants (AICPA). These audits are primarily intended for service organizations that impact their clients' financial reporting. SOC 1 reports are used by service organizations to demonstrate the effectiveness of their internal controls over financial reporting to their clients and auditors.
SOC 2 audits, on the other hand, are conducted in accordance with the AICPA's AT-C section 205, which outlines the criteria for evaluating the controls relevant to the security, availability, processing integrity, confidentiality, and privacy of a service organization's system. These audits are more comprehensive and cover a broader range of controls compared to SOC 1 audits. SOC 2 reports are often used by technology and cloud service providers to assure their clients of the security and reliability of their services.
SOC 3 reports are also based on the same criteria as SOC 2 reports but are intended for a broader audience. Unlike SOC 1 and SOC 2 reports, SOC 3 reports are intended for public distribution and can be used by service organizations to provide a high-level overview of their controls to potential clients and stakeholders.
In conclusion, SOC audits are important for service organizations to demonstrate their commitment to security, availability, processing integrity, confidentiality, and privacy to their clients and stakeholders. By undergoing a SOC audit and obtaining a SOC report, service organizations can provide assurance to their clients that their systems and processes are designed and operated effectively to meet their needs and protect their data. Additionally, SOC reports can help service organizations build trust with their clients, differentiate themselves in the marketplace, and comply with regulatory requirements.
