Understanding SOC 2 trust services criteria
SOC 2 outlines five key criteria that distinguish trustworthy service providers:
SOC 2 trust services criteria
Security is the primary services criterion that evaluates how well an organization protects its data and systems from unauthorized access, damage, and information disclosure. To successfully implement this criterion, organizations may use measures like two-factor authentication and deploy robust access management and user activity monitoring tools.
Security is the only trust criterion that must be included in every SOC 2 Type 2 report.
The availability criterion focuses on an organization’s ability to maintain the minimally acceptable level of network and system performance and mitigate potential external threats. Implementing tools for system performance monitoring and cybersecurity incident response can help organizations ensure the availability of their networks and systems.
The processing integrity criterion aims to evaluate the ability of an organization’s systems to perform without critical errors or delays. To successfully implement this TSC, an organization needs to ensure that its data is processed accurately and only by authorized users and systems.
The confidentiality criterion addresses an organization’s ability to properly limit access to customer data that requires enhanced protection and prevent its unauthorized disclosure. Organizations can implement this trust criterion by setting granular access permissions and ensuring strong encryption for all kinds of sensitive data.
The privacy criterion focuses on the ability of an organization to protect the personally identifiable information (PII) of their customers. An organization is supposed to collect, process, and disclose the PII of customers securely and in accordance with their internal policies as well as with the Generally Accepted Privacy Principles set by the AICPA. This trust criterion can also be implemented by applying robust access management and data encryption capabilities.
Correlation with other compliance requirements
Similarly to ISO 27001, SOC 2 allows organizations to choose the tools and procedures for implementing particular TSCs. Furthermore, implementing all five TSCs isn’t necessary; organizations can decide on their own which of the five criteria to focus their efforts on. The only TSC that’s necessary for SOC 2 compliance is the Security criterion.
As a result, organizations can significantly speed up and simplify the process of achieving SOC 2 compliance by only adopting the practices, tools, and procedures that are relevant to their operations and objectives.
When designing an SOC 2 compliance program, pay attention to the requirements of other IT regulations, laws, and standards that are relevant to your organization. SOC 2 TSCs are closely aligned with key cybersecurity regimes, including:
You can find detailed mappings of SOC criteria to the requirements of key frameworks and cybersecurity standards on the AICPA’s website.
