Organizations rely heavily on third-party vendors and cloud service providers (CSPs) such as Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure, etc. Any mismanagement or mishandling of information or a data breach can compromise the confidentiality, integrity, or availability of information, and leave the organization vulnerable to cyber-attacks. This may result in regulatory fines, legal actions or lawsuits, or financial losses. SOC reports are helpful in assessing the internal control environment of various service organizations (such as CSPs).

Understanding SOC1, SOC2, SOC3 In Detail

An organization willing to migrate to the cloud, may not have direct access to validate and verify internal security controls of a CSP’s information infrastructure because CSPs might not allow them to do so, citing security reasons. Hence, organizations need some means to evaluate a CSP’s control environment, resiliency capabilities, and financial stability, etc., that is where SOC reports come in handy.

So, What Does SOC Stand For?

Who Issues SOC reports?

SOC reports have been established by SSAE 18 (Statement on Standards for Attestation Engagements). SSAE 18 is an auditing standard by AICPA (American Institute of Certified Public Accountants)
