What is the SOC examination process?
The SOC examination process is a multi-step journey that involves organizational preparation, choosing the right auditor, undergoing assessments, and addressing any findings to ensure the organization is safeguarding sensitive data. It involves an independent third-party auditor that assesses the organization’s controls to ensure they meet the necessary criteria for the desired SOC report type (SOC 1, SOC 2, or SOC 3).
This structured, step-by-step process includes preparation, testing, and review, allowing organizations to systematically identify and address potential control deficiencies. Without the SOC examination, there would be no verifiable proof that an organization’s controls are effective. This examination process ensures controls are not only designed well, but also operating as intended.
By engaging in this process, organizations gain valuable insights into their own internal processes, identify areas for improvement, and emerge with a certified report that provides external validation of their security posture. Ultimately, the SOC examination is about more than compliance, it demonstrates an organization’s commitment to maintaining high standards in security and operational controls.
What are SOC examination steps?
There are seven key steps in the SOC examination process, and each stage is critical in ensuring a successful and meaningful outcome.
Stage 1: Planning and preparation
Step 1. Identify the type of SOC examination needed
Understanding the difference between SOC 1 vs SOC 2 vs SOC 3 is important when it comes to determining which type of report your organization requires. Firstly, an organization must determine which type of report is the best fit for their needs:
Understanding SOC 1, SOC 2, and SOC 3
SOC 1
Focuses on internal controls related to financial reporting at a specific point in time. It is primarily used by organizations that impact their clients’ financial statements and is often required for audits.
SOC 2
Focuses on internal controls for security, confidentiality, processing integrity, privacy, and availability of customer data. Commonly used by technology and cloud service providers to demonstrate compliance.
SOC 3
A general-use version of a SOC 2 report designed for public audiences. It provides an overview of an organization’s security and compliance without sensitive details, making it useful for marketing and transparency.
Once the type of report has been identified, you can move on to preparing for the assessment.
Step 2. Preparation and readiness assessment
Before initiating any of the SOC examinations, organizations must engage in comprehensive preparation and the evaluation of the organization’s current state of controls.
This includes:
- Identifying stakeholders from various departments such as IT, Finance, Legal, and Compliance, ensuring they understand their roles in the examination process.
- Identifying the primary systems and services used by customers that are critical to data processing and security.
- Choosing which Trust Service Criteria (TSC) categories (availability, confidentiality, processing integrity, privacy, security) are relevant to your operations and including them in the scope of the examination.
- Reviewing existing organizational controls and workflows to identify deficiencies that could impact the examination. For instance, if an organization processes credit card transactions, sample testing may be conducted to verify compliance with PCI DSS.
- Gather documentation and evidence such as policies, procedures, system logs, and third-party reports (such as ISO 27001 certifications), to demonstrate compliance during the examination.
The findings from the preparation and readiness assessment are then documented, and an action plan is created to remediate any weaknesses. The evidence that has been prepared then gets organized into a centralized repository for easy access during the audit.
Step 3. Choosing an auditor
Selecting a qualified auditor is a critical step in any SOC examination process. Organizations should choose an auditor with industry-specific experience and familiarity with the type of SOC report they need, whether it’s SOC 1, SOC 2, or SOC 3.
Independence is also a key factor, the auditor must be unbiased and not involved in the organization’s day-to-day operations. Certified Public Accountants (CPAs) usually get chosen for SOC examinations due to their credentials and expertise. The identified CPA will assess the organization’s controls and procedures, eventually issuing an official opinion on their effectiveness. Their opinion and findings are added to the final report, which serves as a critical document for the organization’s stakeholders.
Step 4. Planning and scope determination
Once the auditor is selected, the organization and auditor collaborate to plan the examination and define its scope. The auditor and organization work together to establish the objectives of the SOC examination, ensuring that all relevant aspects of the organization’s operations are covered. This phase also includes setting a timeline for the examination and determining the resources needed to support the audit process.
A critical component of this step is conducting a risk assessment, where the organization identifies areas of higher risk that warrant closer scrutiny. For instance, if the organization processes large volumes of sensitive customer data, the scope may prioritize data protection controls. By narrowing the scope and focusing on key risk areas, the organization ensures the examination is thorough and efficient, addressing the critical aspects of its operations.
Stage 2: On-site assessment and testing
Step 1. On-site assessments and testing
Once the planning and scope are established, the auditor begins the on-site assessments. During this phase, the auditor visits the organization’s physical or virtual sites to conduct interviews, review documentation, and test controls to verify their effectiveness.
The auditor evaluates whether the documented policies and procedures are implemented correctly and consistently across the organization. For example, if the organization has an access control policy, the auditor may test whether access to sensitive data is restricted only to authorized personnel. They may also test whether these controls are enforced uniformly across all departments.
This hands-on testing ensures controls are well-designed and function as intended in real-world scenarios. On-site assessments provide the auditor with a comprehensive understanding of the organization’s internal controls, helping to identify any gaps or inconsistencies that need addressing.
Step 2. Auditor reporting and management response
After completing the on-site assessments and testing, the auditor compiles their findings into a draft report. This report details the effectiveness of the organization’s controls and highlights any deficiencies or areas that need improvement.
The organization may review the draft report and provide management responses to the auditor’s findings. In this phase, the organization addresses any weaknesses identified during the examination, outlining specific actions to remediate those deficiencies.
Management responses are crucial because they demonstrate the organization’s commitment to improving controls and provide an opportunity to clarify any misunderstandings or potential errors. The auditor reviews the management’s responses, incorporating them into the final report. This process allows the organization to make necessary adjustments and helps them strengthen its controls before the final SOC report is issued.
Stage 3: Final reporting and follow-up
Step 1. Final report and distribution
Once all findings are reviewed and management responses are integrated, the auditor will finalize the SOC report. The final report includes the auditor’s opinion on the effectiveness of the organization’s internal controls, along with any identified gaps or recommendations for improvement.
This document is an essential resource for the organization’s stakeholders—clients, partners, and regulators—by providing a transparent view of the organization’s control environment. The final report is distributed to relevant parties, demonstrating the organization’s commitment to compliance and data security.
In some cases, organizations may share the SOC report publicly or with prospective clients to build trust and credibility. Beyond the immediate examination, the insights from the final report often serve as a roadmap for continuous improvement, guiding the organization in maintaining robust controls and enhancing its overall security posture in the future.
