Case Study: Journey to Information Security Excellence at NRS
Executive Summary
The Nigeria Revenue Service (NRS) embarked on a transformative journey towards information security excellence in April 2019. By partnering with iCentra for the implementation of the ISO 27001 – Information Security Management System (ISMS), NRS demonstrated a strong commitment to securing its information assets. This case study chronicles the key milestones, achievements, and lessons learned from this five-year journey.
Background
Organizational Context
As a critical institution in Nigeria’s economic landscape, NRS recognized the need to strengthen its information security practices. The rapidly evolving threat landscape necessitated a robust framework to:
- Protect sensitive organizational data
- Enhance operational resilience
- Align with global best practices
Initial Challenge
Prior to the intervention, NRS faced challenges in:
- Establishing a formalized information security management system
- Achieving compliance with international standards
- Building organizational capacity in information security
Project Approach
Partnership with iCentra
In April 2019, NRS engaged iCentra as its ISMS consultants to lead the implementation of ISO 27001. The project was executed in two structured phases:
Phase 1: Gap Assessment (April – October 2019)
- Comprehensive evaluation of existing information security practices
- Identification of gaps and improvement opportunities
Phase 2: Implementation (October 2019 – April 2021)
- Development and deployment of the ISMS framework
- Certification of the EOI Center by BSI in April 2021
Key Project Milestones
- July 2021: Official presentation of the ISO/IEC 27001:2013 certification to NRS management.
- May 2022 & April 2023: Successful completion of the first and second surveillance audits.
- May 2024: Recertification and transition to ISO/IEC 27001:2022 under the leadership of the Executive Chairman. This milestone was achieved with zero non-conformities, and all opportunities for improvement (OFIs) were promptly resolved, leading to re-certification by BSI.
