ISO 27018

Code of Practice for Protection of Personally Identifiable Information (PII) in Public Clouds

Keeping personally identifiable information (PII) safe has become a growing concern in recent years, leading to a flurry of extra legislation to protect it.

To provide guidance to companies who operate cloud services that also act as processors of PII, the ISO (International Organisation for Standards) has developed this extension of its Information Security Management Standard (ISO 27001). 

ISO 27018 specifically targets cloud service businesses that process PII, providing relevant controls and guidance to keep this data safe. This enables businesses to demonstrate that they have robust processes in place, giving customers, stakeholders and suppliers far greater confidence in their operations.

What is ISO 27018?

ISO 27018 is a code of practice designed to protect personally identifiable information (PII) in public clouds.

It is an extension of ISO 27001, the Standard for Information Security Management, and it was designed to provide much-needed detail and guidance on the operation of cloud services. This can help you to create a more comprehensive, relevant and focused Information Security Management System (ISMS).

ISO 27018 also builds on the requirements of ISO 27002, which provides the detailed implementation of ISO 27001 security controls. ISO 27018 includes these controls and expands upon them to include ones that relate directly to the management of PII in clouds.

The benefits of ISO 27018

Top benefits of achieving certification in ISO 27018 include:

  1. Implementing controls that are highly relevant to businesses that operate cloud services and act as PII processors, ensuring a ‘best fit’ for your company’s operations.
  2. The development of a secure and transparent system, boosting the confidence of customers, suppliers and stakeholders.
  3. An expansion of the framework and controls of ISO 27001 and ISO 27002 for a more comprehensive Information Security Management System (ISMS).
  4. International recognition that your business operates best practice when it comes to managing PII within your cloud service.

How much does ISO 27018 cost?

The cost of ISO 27018 depends on whether you already have an existing ISO 27001 Information Security Management System.

ISO 27018 is an extension of the ISO 27001 Information Security Management System Standard, which means it cannot be implemented as a standalone product. If you haven’t yet achieved certification in this Standard, you will therefore need to implement ISO 27001 alongside ISO 27018 in order to achieve the certification you are looking for.

Frequently Asked Questions

Do I need to get ISO 27001 in order to have ISO 27018?

What is the difference between ISO 27001 and ISO 27018?

ISO 27018 Certification Process

Becoming certified to ISO 27018 is a straightforward process, whether you are adding it to your existing ISO 27001 system or are implementing both.

If you already have ISO 27001, the process will be a little quicker as you will already have some supportive frameworks in place. However, you will still go through the same three-step process as businesses that are implementing both Standards at once.

During the process, our consultant will also identify your business and team members as information controllers, processors or both. This will depend on whether you are the person (or business) who determines the purposes for which, and the way in which, personal information is processed, or the person (or business) who processes personal information on behalf of the information controller. This early classification will remove unnecessary complexity.

    Gap Analysis

    A QMS Consultant will visit your Organisation to review and document your current processes and procedures, highlighting any areas that do not meet the requirements of the Standard.

    An Auditor must now visit your Organisation to check that the documented processed are being followed and that the necessary changes have been made. Once they are satisfied, you will be rewarded with your certification.

    3 Step Certification

Once you have achieved certification the certification cycle will commence. This is made up of surveillance and re-certification audits, one of which must take place each year, around the anniversary of your certification. These visits confirm your continued compliance with the Standard and verify the validity of your certification.
