ISO 27001

ISO/IEC 27001 — Information Security Management System (ISMS)

The global gold standard for information security management

What is ISO 27001?

ISO/IEC 27001 is the internationally recognized standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Published jointly by ISO and IEC, it provides a systematic approach to managing sensitive company information so that it remains secure.

The standard adopts a risk-based approach, requiring organizations to identify information security risks and select appropriate controls to mitigate them. It covers people, processes, and technology, ensuring a holistic approach to information security across the entire organization.

ISO 27001 certification is awarded by accredited certification bodies after a successful external audit, demonstrating to customers, partners, and regulators that your organization takes information security seriously.

How ISO 27001 Works

ISO 27001 implementation follows a structured approach based on the Plan-Do-Check-Act cycle, typically taking 6-12 months depending on organizational complexity.

Define the ISMS Scope

Determine the boundaries and applicability of the ISMS, including organizational units, locations, assets, and technologies to be covered.

Conduct Risk Assessment

Identify information security risks, analyze their likelihood and impact, and evaluate them against your risk acceptance criteria.

Select and Implement Controls

Choose appropriate controls from Annex A and other sources to treat identified risks. Implement technical, organizational, and physical controls.

Develop Policies and Procedures

Create the required documented information including the information security policy, risk treatment plan, Statement of Applicability (SoA), and operational procedures.

Awareness and Training

Ensure all personnel understand their information security responsibilities through targeted awareness programs and role-specific training.

Internal Audit

Conduct planned internal audits to verify the ISMS conforms to requirements and is effectively implemented and maintained.

Management Review

Top management reviews the ISMS at planned intervals to ensure its continuing suitability, adequacy, and effectiveness.

Certification Audit

An accredited certification body conducts a Stage 1 (documentation review) and Stage 2 (implementation audit) to assess conformity and award certification.
