ISO 27001 vs SOC 2: Understanding the Differences

Introduction

ISO 27001 is an International Standard that outlines the best practices for implementing an Information Security Management System [ISMS]. The Standard provides a systematic approach to managing sensitive Company information, ensuring its confidentiality, integrity & availability. On the other hand, SOC 2 is a set of guidelines established by the American Institute of CPAs [AICPA] that evaluates an Organisation’s security, availability, processing integrity, confidentiality & privacy controls.

The importance of information security & data privacy cannot be overstated. The modern business environment is characterised by an increased amount of data & this data is frequently the lifeblood of many Organisations. Companies must take adequate measures to protect sensitive information & safeguard their reputation, brand & customer trust.

In this Journal, we will explore the differences between ISO 27001 & SOC 2 in detail. We will provide an overview of the contents of each framework, highlighting their unique features & how they address different security needs. By the end of this Journal, you will have a clear understanding of the key differences between these two frameworks & be better equipped to select the one that best suits your Organisation’s security needs.

Understanding ISO 27001 vs SOC 2

To gain a deeper understanding of the differences between ISO 27001 & SOC 2, it is important to first understand the scope & requirements of each framework.

ISO 27001 is an International Standard that provides a systematic approach to managing sensitive company information. The Standard outlines the best practices for implementing an Information Security Management System [ISMS] & sets out a comprehensive set of security controls that Organisations should implement to ensure the confidentiality, integrity & availability of their data. The purpose of ISO 27001 is to provide a framework for companies to establish, implement, maintain & continually improve their Information Security Management Systems.

On the other hand, SOC 2 is a set of guidelines established by the American Institute of CPAs [AICPA] that evaluates an Organisation’s security, availability, processing integrity, confidentiality & privacy controls. SOC 2 Reports are based on the Trust Services Criteria [TSC], which are a set of principles used to evaluate an Organisation’s information systems’ security, privacy, availability, processing integrity & confidentiality. The purpose of SOC 2 is to provide a comprehensive report that details an Organisation’s information security & data privacy controls, thereby assuring customers & stakeholders that their data is secure.

The scope & requirements of ISO 27001 & SOC 2 differ slightly. ISO 27001 requires Organisations to establish & maintain an ISMS that includes risk management, security policies, procedures & controls, as well as ongoing monitoring & continual improvement. The Standard also requires Organisations to conduct regular risk assessments, implement controls to manage identified risks & maintain documentation to demonstrate compliance.

SOC 2, on the other hand, does not require Organisations to establish a formal ISMS. Instead, it evaluates an Organisation’s controls based on the Trust Services Criteria [TSC] & provides a comprehensive report detailing the effectiveness of these controls. The TSC is a set of principles that focus on five key areas: security, availability, processing integrity, confidentiality & privacy. An Organisation must select which of these areas it wishes to be evaluated on when it undergoes a SOC 2 Audit.

Key Differences: ISO 27001 vs SOC 2

While ISO 27001 & SOC 2 share some similarities, there are several key differences between the two frameworks. Let’s take a closer look at these differences:

Comparison of Trust Service Principles [TSPs] & ISO 27001 requirements:

SOC 2 evaluates an Organisation’s controls based on five Trust Service Principles [TSPs]: security, availability, processing integrity, confidentiality & privacy. ISO 27001, on the other hand, requires Organisations to establish & maintain a comprehensive set of security controls that cover risk management, security policies, procedures & controls, as well as ongoing monitoring & continual improvement.

While both frameworks address security & confidentiality, ISO 27001’s scope is broader, covering risk management & ongoing monitoring, while SOC 2’s TSPs cover additional areas such as availability & processing integrity.

Differences in Audit processes & reporting:

ISO 27001 & SOC 2 have different Audit processes & reporting requirements. ISO 27001 requires Organisations to undergo an External Audit conducted by an accredited third-party Certification body, which assesses the Organisation’s Compliance with the Standard’s requirements. The Audit process involves reviewing documentation, interviewing staff & conducting on-site inspections. Once the Audit is complete, the Certification Body issues a Certification that is valid for three years.

In contrast, SOC 2 Reports are not Certifications but rather a detailed report outlining the effectiveness of an Organisation’s controls based on the TSPs. The Report is conducted by an Independent Auditor who assesses the Organisation’s Controls against the chosen TSPs. The Report is then provided to the Organisation, which can share it with its customers & stakeholders to demonstrate its security posture.

Considerations for choosing between ISO 27001 & SOC 2:

When choosing between ISO 27001 & SOC 2, several factors need to be considered, including the Organisation’s industry, risk appetite & regulatory requirements. ISO 27001 is a more comprehensive framework that requires a higher level of investment & effort to implement but provides a more robust & structured approach to information security management. SOC 2, on the other hand, is more flexible & adaptable, making it a good fit for Organisations that want to demonstrate their security posture to customers & stakeholders.

While both ISO 27001 & SOC 2 address information security & data privacy, there are key differences between the two frameworks in terms of Scope, Audit Processes & Reporting. Choosing the right framework depends on an Organisation’s specific security needs, industry & regulatory requirements.

Advantages of ISO 27001 & SOC 2

Both ISO 27001 & SOC 2 offer significant advantages for businesses in terms of information security management, compliance with data privacy regulations & overall risk management.
