Implementation and Certification ISO 27001 Standard (ISMS) 

The ISO/IEC 27001 standard demonstrates the commitment of companies and organizations to proactively manage and protect their information and assets and ensure compliance with legal requirements. 

The ISO/IEC 27001 standard adopts a process approach to establish, implement, operate, monitor, review, maintain and improve an organization’s information security management system. The ISO/IEC 27001 standard was established by the International Organization for Standardization (ISO) for the first time in 2005, as a replacement for BS 7799. 

In addition, and building on the requirements of ISO/IEC 27001, ISO/IEC 27701 provides requirements and helps companies manage privacy risks related to personally identifiable information. It can also help companies comply with GDPR and other data protection regulations. 

The ISO/IEC 27001 scheme emphasizes continuous process improvement of your information security management system, defines documentation and record keeping requirements, and involves risk assessment and risk management processes using a Plan, Do, Check, Act (PDCA) process model. 

The ISO/IEC 27001 standard helps companies and organizations to protect their information in terms of the following principles: 

• Confidentiality ensures that information is accessible only to those authorized to have access. 
• Integrity protects the accuracy and integrity of information and processing methods. 
• Availability ensures that authorized users have access to information and associated assets when needed. 

It is important to consider whether this standard is right for your company before embarking on the certification process. Here are some key aspects to consider when assessing the suitability of ISO 27001 for your company: 

ISO 27001 Information Security Management System (ISMS) certification is a rigorous process that requires proper planning, effective implementation and thorough assessment. Here are the key steps to obtain ISO 27001 ISMS certification: 

1. Understanding the requirements: Familiarize yourself with the requirements of ISO 27001 and make sure you understand how they apply to your organization. Study the standard and its associated guidelines to get a clear view of the key elements that need to be addressed. 
2. Initial assessment or Gap Analysis: Conduct an initial assessment of the current information security situation in your organization. Identify critical information assets, assess security risks and determine the existing gaps in relation to ISO 27001 requirements.
3. Consultancy: Seek the advice of a consultancy specializing in information security and ISO certifications. An experienced consultant can help your organization design and implement an Information Security Management System (ISMS) in accordance with the requirements of ISO 27001. The consultant will provide expert guidance, develop policies and procedures, and assist in staff training and awareness. 
4. ISMS Planning: Develop an ISMS implementation plan based on the results of the initial assessment. This plan should include required security controls, personnel roles and responsibilities, required resources and an implementation schedule. 
5. ISMS implementation: Implement the security controls and measures defined in the ISMS plan. This involves establishing policies and procedures, training and raising staff awareness of information security, implementing technical and organizational controls, and establishing a risk management system. 
6. Internal audit: Conduct an internal audit to verify the conformity of your ISMS with the requirements of ISO 27001. This audit should be performed by competent and independent personnel within your organization. The results of the internal audit will allow you to identify any gaps or non-conformities prior to the external audit. 
7. External audit: Engage an accredited certification body to perform an external audit of your ISMS. The certification body will review your documentation, conduct an on-site audit and assess whether your ISMS meets the requirements of ISO 27001. During this stage, the consultancy can provide additional support to ensure adequate preparation. 
8. Corrective actions: If nonconformities are identified during the external audit, implement corrective actions to address them. These actions should correct the gaps and ensure conformity with the requirements of the standard. 
9. Certification: Once all non-conformities have been addressed, the certification body will issue the ISO 27001 ISMS certificate if the requirements of the standard are met. This certificate is valid for a limited period of time and requires periodic follow-up audits to maintain it. 

Remember that the certification process may vary depending on the organization and specific circumstances. It is advisable to seek expert advice and consult with an accredited certification body for detailed information on the ISO 27001 ISMS requirements and certification process. In addition, the implementation of an ISMS should be a continuous and evolving process to ensure effective protection of information in your organization. 

The Information Security Management System based on the UNE-ISO/IEC 27001 standard, is transversal in application, all sectors of economic and business activity are susceptible to implementation and certification.
