ISO27001

What does ISO 27001 mean?

ISO 27001 is an internationally recognized standard for information security management systems (ISMS). Published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), it outlines the requirements for establishing, implementing, maintaining, and continually improving an ISMS to safeguard sensitive information.

How does ISO 27001 work?

ISO 27001 is structured around a risk-based approach. Organizations start by identifying information security risks and then design and implement controls to address those risks. The standard outlines 93 control objectives and controls in Annex A (as of the 2022 update), categorized under themes such as:

  • Organizational controls (e.g., policies, roles, and responsibilities)
  • People controls (e.g., training and background checks)
  • Physical controls (e.g., facility security)
  • Technological controls (e.g., access management, encryption)

Companies can seek ISO 27001 certification to demonstrate that their ISMS meets the standard’s criteria. Certification involves an external audit by an accredited certification body.

ISO 27001 plays a critical role in building trust with customers, partners, and regulators through the following:

  • Data protection: Helps safeguard personal and business-sensitive data against breaches and leaks.
  • Compliance alignment: Supports adherence to global privacy laws like the GDPR, HIPAA, or CCPA by demonstrating robust information security practices.
  • Risk management: Encourages proactive identification and mitigation of security risks.
  • Business reputation: Enhances credibility and marketability by showing commitment to security best practices.
  • Competitive edge: Can be a key differentiator in industries where data security is a buyer requirement.
