ISO 27001 Guide
ISO/IEC 27001 is an international standard related to information security. Initially published in 2005, it has evolved to address the changing threat landscape. The most recent version is ISO/IEC 27001:2022.
Its primary purpose is to define a framework for implementing an Information Security Management System (ISMS).
This guide will support you from your first steps through to a potential ISO/IEC 27001 certification.
ISO/IEC 27001 is an information security management standard recommended by ENISA and recognized worldwide. It is a key tool for raising and demonstrating a security level. ISO/IEC 27001 certification may provide a presumption of NIS 2 compliance in certain countries of the European Union. It is complemented by ISO/IEC 27002, which defines detailed security controls.
ISO/IEC 27001 helps structure your security around processes, roles, and policies in order to manage risk over time through an ISMS (Information Security Management System). This ISMS enables organizations to define, implement, and maintain solutions that address the 93 security controls listed in the ISO/IEC 27002 standard.
The ISO 27001 in 3 steps
Define the scope
ISO/IEC 27001 applies to a defined scope. It is possible to certify your entire organization, but you may also limit the scope to a single department or function.
For example, consider your IT department. As the true core of your operations, it is logical to certify it first in order to preserve your operational capability.
Organize the defense
Define your ISMS (Information Security Management System) and ensure a PDCA continuous improvement cycle:
- Plan
- Do
- Check
- Act
Deploy your weapons
Annex A of ISO/IEC 27001 refers to ISO/IEC 27002, which lists 93 security controls. These controls are organized into four categories of security measures:
- Organizational
- People-related
- Physical
- Technological
Good to know: entities subject to the NIS 2 or CER Directives require their suppliers and partners to hold ISO/IEC 27001 certification, either fully or partially. The same applies to insurers seeking to limit their risk exposure.
Build your ISO 27001 team
Pursuing ISO/IEC 27001 certification requires building a team that covers all the necessary skills. Every relevant business expertise should be represented, whether specialized or cross-functional, depending on your objectives:
- Governance and compliance: executive management, security committee, quality department, regulatory coordination.
- Operational cybersecurity: CISO, security architects and engineers, system and network administrators, detection and response analysts.
- Infrastructure and physical security: site managers, facility managers, operations managers, integrators and maintenance providers.
- Risk management and audit: risk managers, internal auditors, external assessors, action plan management.
- Cross-functional expertise: legal teams, DPOs, training and awareness managers, crisis communication.
If you have all these resources in place, implementing ISO/IEC 27001 can be done smoothly and in a controlled manner. Otherwise, external support is, in our view, essential. Keep the following points in mind:
- Any weakness in the organization of your ISMS will delay your certification, generating both direct and indirect costs.
- A poor choice of hardware or software solutions can prevent certification: selecting the right providers is critical (and they should be involved early in the process).
- European regulations are clear: the personal liability of executive management may be engaged in the event of a failure under certain directives such as NIS 2 and the CER Directive.
By relying on certified specialists, you will optimize your investment while reducing your exposure to liability.
