ISO/IEC 27001 at a Glance

What Is ISO/IEC 27001?

ISO/IEC 27001:2022 specifies requirements for an Information Security Management System, or ISMS.

An ISMS provides a structured framework for establishing, implementing, maintaining and continually improving information security management.

It helps organizations manage information security risks through a holistic approach involving people, policies, processes and technology. ISO/IEC 27001 can be applied by organizations of different sizes and sectors.

Three fundamental principles sit at the center of information security:

Confidentiality

Information is accessible only to authorized people.

Integrity

Information remains accurate, complete and protected from unauthorized alteration.

Availability

Information and relevant systems remain accessible and usable when required.

Where Can Information Security Risk Affect Your Organization?

Information security risks can arise across everyday business activities, systems and relationships.

People

Employees, contractors and other users may create, access, share or manage important information. Clear responsibilities, appropriate access, competence and awareness therefore form part of effective information security management.

Business Processes

Information moves through activities such as customer management, recruitment, procurement, finance, operations and project delivery. How that information is created, handled, shared, retained and protected can affect information security risk.

Technology

Applications, cloud services, networks, devices and other systems may store, process or provide access to important information. Relevant risks and controls should reflect the organization’s actual technology environment and business use.

External Parties

Suppliers, technology providers and outsourced service providers may access, process, store or support organizational information and systems. Information security responsibilities and risks associated with external relationships should therefore be considered.

Information Assets

Important information may exist across digital systems, cloud environments, communications and physical records. Understanding what information matters, where it is used and what could affect its confidentiality, integrity or availability provides a stronger foundation for risk assessment.

When Is ISO/IEC 27001 Relevant?

ISO/IEC 27001 may be relevant when information security becomes an important business, customer, contractual or operational consideration.

• Managing confidential or sensitive information

• Handling customer, employee, supplier or business information

• Relying on applications, digital systems or cloud services

• Managing intellectual property or commercially sensitive information

• Working with technology providers or other external parties

• Responding to relevant customer, contractual or tender requirements

• Strengthening information security governance and accountability

• Establishing a structured approach to information security risk management

• Preparing an ISMS for independent certification

ISO/IEC 27001 is designed for organizations across different sizes and sectors rather than for technology companies alone.

Key Areas of an ISO/IEC 27001 ISMS

Context & Scope

Understand the organization, relevant interested parties and the boundaries of the ISMS.

Leadership & Governance

Establish management commitment, responsibilities, policies and direction for information security.

Planning & Risk Management

Identify, assess and treat information security risks. Determine the controls needed for risk treatment and maintain a Statement of Applicability that documents the necessary controls and justifies relevant inclusions and exclusions.

Support & Resources

Provide appropriate resources, competence, awareness, communication and documented information.

Information Security Controls & Operation

Implement and manage the controls selected through the risk-treatment process. ISO/IEC 27001 Annex A groups its reference controls into four themes:

• Organizational controls

• People controls

• Physical controls

• Technological controls

Performance Evaluation

Monitor ISMS performance and conduct internal audits and management reviews.

Improvement

Address nonconformities, implement corrective actions and continually improve the ISMS.
