ISO 27001 and the GDPR

How ISO 27001 can help you comply with the GDPR

The EU General Data Protection Regulation (GDPR) requires organizations to adopt appropriate technical and organizational measures – including policies, procedures, and processes – to protect the personal data they process.

ISO 27001, the international standard for an ISMS (information security management system), provides an excellent starting point for achieving the technical and operational requirements necessary to reduce the risk of a breach.

ISO 27701, meanwhile, specifies the requirements for – and provides guidance for establishing, implementing, maintaining, and continually improving – a PIMS (privacy information management system) based on the requirements, control objectives and controls in ISO 27001, and extended by a set of privacy-specific requirements, control objectives, and controls.

Organizations that have implemented ISO 27001 will be able to use ISO 27701 to extend their ISMS to cover privacy management – including data processing.

Implementing both standards will help you meet – and demonstrate your compliance with – the privacy and information security requirements of the GDPR.


Does the GDPR offer guidance for avoiding a data breach?

Article 32 of the GDPR specifically requires organizations to, as appropriate:

  • Take measures to pseudonymise and encrypt personal data
  • Ensure the ongoing confidentiality, integrity, availability, and resilience of processing systems and services
  • Restore the availability and access to personal data in a timely manner in the event of a physical or technical incident, and/or
  • Implement a process for regularly testing, assessing, and evaluating the effectiveness of technical and organizational measures for ensuring the security of processing.

Article 32 further requires risks “from accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to personal data” to be identified and mitigated.

An ISMS that conforms to ISO 27001 will meet all the above requirements.

Article 32 of the GDPR is the primary provision requiring technical measures to protect data. Although it gives examples of security measures and controls, the article does not provide detailed guidance regarding what you should do to achieve this.

Instead, the GDPR, compels companies to look at existing best practices and recommendations, such as ISO 27001, to minimise the risk of a data breach.


How ISO 27001 works

ISO 27001 describes best practice for an ISMS, a systematic approach consisting of people, processes, and technology that helps you protect and manage all your organization’s information through risk management.

An ISMS aligned to ISO 27001 brings about many organizational benefits, such as:

  1. The ability to provide convincing evidence that the necessary measures have been taken to comply with the data security requirements of the GDPR
  2. The protection of all corporate information and intellectual property – not just personal data
  3. The ability to reduce, monitor, and review risks as well as keep up with constantly evolving data security threat
  4. A culture of awareness surrounding information security

Why technical measures aren’t enough for GDPR compliance

Companies often mistakenly believe that adding layer upon layer of state-of-the-art technology will help them prevent a data breach. They couldn’t be more wrong. Why?

  • Without a comprehensive information security program that also considers people and processes, your technology will fall short of providing adequate protection.
  • Poor company processes and staff-related problems are among the most common points of failure in data security.
  • Without leadership commitment (an essential criterion for ISO 27001 compliance), the best-laid information security plans have been proven to fail.
  • ISO 27001 compliance means the company is constantly reviewing and updating its ISMS in line with changes to the threat environment and business developments.
  • Without an effective management system, controls are often left in isolation, becoming redundant and dysfunctional.
  • Obtaining certification to ISO 27001 helps the business to get an external, expert assessment of the efficacy of its information security plans, thereby making sure that the measures it has implemented are working.

GDPR compliance with ISO 27001

Ignoring or failing to fully comply with the GDPR could be costly for your organisation. An ISO 27001-aligned ISMS can help you achieve GDPR compliance in a cost effective manner. Download our free green paper to learn more about how ISO 27001 can aid your journey to compliance.

What else should you do?

In addition to achieving compliance with ISO 27001, your organization must meet certain additional requirements in the GDPR that are covered by a privacy framework such as ISO 27701. Implementing both standards will enable you to meet the privacy and information security requirements of the GDPR and other data protection laws.
