Relationship Between ISO 27001 & KVKK

Providing security of your information assets is part of Turkish Personal Data Protection Law (KVKK) and by creating an information security system for your business, having an ISO 27001 certification is the best way to document the measures taken by your organization in this context.

The purpose of ISO 27001 standard is to lay down conditions for establishing, implementing, maintaining, and continually improving an information security management system.

Information Security Management System maintains the confidentiality, integrity, and accessibility of information by applying the risk management process and provide assurance to related parties / parties interested that risks are managed properly.

The international ISO 27001 standard which consists of general requirements and Annex A controls, explains the details required for organizations to ensure information security.

Are Organizations with ISO 27001 Certificate
Compliant with KVKK?

The first paragraph of Article 12 of KVKK that came into force in April 7th, 2016, sets forth the following provisions:

"The data controller is obliged to

a) prevent unlawful processing of personal data,

b) prevent unlawful access to personal data,

c) take all necessary technical and organizational measures to provide an appropriate level of security.”

The measures to be taken within this scope are elaborated in the Personal Data Security Guide (Technical and Administrative and Organizational Measures) published by Turkish Data Protection Authority.

The fact that the general principle of both ISO 27001 and KVKK is to ensure confidentiality and security, surely enables Organizations with ISO 27001 certification to adapt to KVKK faster and smoothly.

However, it would be a great mistake for the organizations to think that they have become fully compliant with KVKK by taking only the measures within the scope of the standards due to existence of important points that distinguish KVKK and ISO 27001 from each other.

What are the similar aspects between the technical measures to be taken within the scope of the Law on the Protection of Personal Data and the control items included in the ISO 27001 standard?

The points stated in the tables above indicate that the Standard and the Law have controls over the same headings, however the terms and requirements of the controls are not exactly the same.

For example, while training and awareness activities are a control item in both aspects, the content and conditions of the training should be customized.

In addition, although the inventory preparation required within the scope of KVKK is also encountered in ISO 27001 as Inventory of Assets, it is not possible to state that an organization with an Inventory of Assets also has a Personal Data Inventory, as the conditions for the preparation of inventories differ from each other.
