As of my last knowledge update in September 2021, ISO 27001:2013 was the latest version of the ISO 27001 standard for information security management systems. The ISO standards are periodically revised and updated to align with changing technology and security needs. I do not have information about the specific release of ISO 27001 in 2022 or later because my knowledge is not current beyond that date. However, the general process for obtaining ISO 27001 certification in Nigeria remains largely consistent regardless of the specific version.

Here are the general steps to obtain ISO 27001 certification in Nigeria:

1. Understanding the Standard: Familiarize yourself with the requirements of ISO 27001. Ensure that you have the latest version of the standard (whether its ISO 27001:2013 or a newer version).

2. Gap Analysis: Conduct a gap analysis to assess your current information security management system against the requirements of ISO 27001. Identify areas where your organization already complies and areas that need improvement.

3. Management Commitment: Obtain commitment and leadership support from top management. Establish an information security policy and objectives.

4. Documentation: Develop the necessary documentation, including an information security policy, risk assessment, policies, procedures, and records, to support your information security management system (ISMS).

5. Risk Assessment and Management: Identify and assess information security risks, and implement controls to manage and mitigate those risks.

6. Employee Training: Ensure that employees are trained and aware of information security best practices and their roles in the ISMS.

7. Implementation: Implement the required processes and controls to meet ISO 27001 requirements. This includes information security policies, incident response, access control, and data protection measures.

8. Internal Audit: Conduct internal audits to verify that the ISMS is effectively implemented and identify areas for improvement.

9. Management Review: Hold regular management reviews to assess the performance of the ISMS and make necessary improvements.

10. Certification: Organizations can choose to seek ISO 27001 certification from accredited certification bodies. These certification bodies will assess your ISMS and, if found compliant, issue ISO 27001 certificates.

11. Continuous Improvement: Continuously monitor and improve your ISMS to enhance overall information security and adapt to evolving threats.

To ensure the latest and most accurate information, you should contact an accredited certification body in Nigeria and inquire about the specific version of ISO 27001 that they are certifying against and the steps for certification in 2022 or later.

Working with experienced information security consultants and professionals can be valuable to help guide you through the ISO 27001 certification process and ensure compliance with the latest standards and best practices.
