ISO 27001: Information Security Management

What is ISO 27001?

ISO 27001 is the world's leading international standard for Information Security Management Systems (ISMS). It provides a systematic approach to managing sensitive company information, ensuring it remains secure through a comprehensive framework of policies, procedures, and controls.

Think of ISO 27001 as a fortress for your digital assets. In an age where data breaches cost companies millions and destroy reputations overnight, this standard provides the blueprint to protect your information from cyber threats, unauthorized access, and data loss.

Simple Analogy: Imagine your organization's information as valuable treasure. ISO 27001 is like a multi-layered security system—it identifies what treasure you have, assesses threats (thieves, natural disasters), implements defenses (vaults, guards, alarms), monitors for breaches, and continuously improves security based on new threats.

Historical Context: First published in 2005 and revised in 2013 and most recently in 2022, ISO 27001 has evolved to address emerging cyber threats. The 2022 version updated the control set (Annex A) from 114 to 93 controls, reorganized into four themes: Organizational, People, Physical, and Technological.

Core Principle: ISO 27001 is built on the CIA triad: - Confidentiality: Information is accessible only to authorized individuals - Integrity: Information is accurate and complete - Availability: Information is accessible when needed by authorized users
