Understanding the CBN Risk-Based Cybersecurity Framework
The foundation of the CBN's approach to IT auditing is the Risk-Based Cybersecurity Framework and Guidelines. It shifts the regulatory focus from merely possessing security tools to proving that a continuous, governed security process is actively managing risk.
Document preparation (Weeks 1-3)
Gather all core policies: Information Security Policy, Incident Response Plan, Business Continuity Plan (BCP), and Disaster Recovery Plan (DRP). Ensure these are signed by the board or executive management within the last 12 months.
Evidence collection (Weeks 3-5)
Policies mean nothing without evidence. Collect recent penetration test reports, vulnerability scan results, access review logs, patch management records, and employee security awareness training certificates.
Asset inventory alignment (Weeks 5-6)
Auditors will cross-reference your critical asset register with your security testing scope. Ensure every public-facing IP, API endpoint, and mobile application listed in the inventory was included in your recent security assessments.
What CBN auditors actually check
Auditors don't typically run technical exploits. They look for the governance trail that proves your engineering team is doing what your policies claim. Expect deep dives into the following areas:
- Access Control Logs: Proof that terminated employees have access revoked within 24 hours.
- Incident Response Capability: Evidence of tabletop exercises and post-incident reports.
- Third-Party Risk Management: Security questionnaires and SLAs for all integrated vendors (payment processors, cloud hosts).
- Continuous Assessment: Proof of annual independent penetration testing and regular vulnerability scanning.
Missing an independent penetration test for your upcoming CBN audit?

The "Clean" Penetration Test Report
A penetration test report that shows zero findings is a massive red flag for a CBN auditor. It suggests the testing was superficial (e.g., an automated scanner dump). Auditors want to see a report that details critical and high vulnerabilities, accompanied by a retest report proving your engineering team remediated those findings. This demonstrates a functioning security lifecycle.
Outdated policies
A beautifully written Information Security Policy from 2021 is an automatic failure in 2026. The framework requires an annual review and board-level approval of all security policies.
Unscoped shadows IT
If your licensing application lists a new USSD service, but your penetration test report only covers the web application, the auditor will flag the gap. Ensure your testing scope accurately reflects your entire attack surface.
The CSAT submission requirement
The Cybersecurity Self-Assessment Tool (CSAT) is an annual mandate. By March 31st, Payment Service Providers (PSPs) and other licensed entities must submit a true reflection of their security posture. Falsifying this submission or failing to provide the requested evidence (like an independent pentest report) can lead to severe operational penalties from the CBN.
Audits are won in the evidence folder
The engineering team shouldn't be scrambling to compile logs the day the auditors arrive. Treating compliance as a point-in-time event guarantees failure. Maintain a continuously updated, centralized repository of security evidence, access logs, and independent assessment reports.
