ISO 27001 vs GDPR: How to Align Security and Privacy Regulations

Introduction

In today’s digital landscape, organizations face the dual challenge of protecting sensitive data while ensuring compliance with multiple regulatory frameworks. Two (2) of the most significant standards in this realm are ISO 27001 & GDPR. While they may seem similar at first glance, understanding the relationship between ISO 27001 vs GDPR is crucial for businesses aiming to build robust data protection strategies. This comprehensive journal will explore how these frameworks interact & complement each other, providing organizations with practical insights for implementation.

Understanding the Basics

What is ISO 27001?

ISO 27001 is an international standard that provides a framework for establishing, implementing, maintaining & continually improving an Information Security Management System [ISMS]. This standard takes a risk-based approach to information security, helping organizations protect their information assets through systematic management of risks.
