What Is an NRS Integration Security Assessment?
A focused guide for certified System Integrators and Access Point Providers on mbs.gov.ng: what an NRS integration security assessment covers, why it matters, and how to prepare.
## What Is an NRS Integration Security Assessment?
An NRS Integration Security Assessment is an independent security review of the systems that connect your organization to the Nigeria Revenue Service (NRS). It is designed for certified System Integrators and Access Point Providers listed on mbs.gov.ng, as well as pension administrators, employers, and any organization transmitting revenue data through an NRS integration.
Unlike a generic penetration test, this assessment focuses on the specific risks that come with revenue-service integrations: API exposure, webhook integrity, taxpayer data protection, access control between tenants, and the trust boundary between your platform and the revenue service.
## Why NRS Integrations Need Specialized Security Testing
Revenue integrations move high-value data. A single misconfigured endpoint, weak access-control check, or insecure callback handler can expose taxpayer information, merchant records, or collection data. Beyond the technical impact, this creates NDPA 2023 reporting obligations and regulatory scrutiny.
Generic scanners and checklist audits are not enough because they do not understand:
- NRS-specific authentication and token lifecycle
- Webhook and callback forgery scenarios
- Multi-tenant data separation between integrators
- The compliance expectations of Nigerian revenue and data-protection regulators
A specialized assessment looks at the integration as an attacker would: from the public API surface through to the internal systems that process and store revenue data.
## What the Assessment Covers
### 1. API & Webhook Security Review
Authentication strength, authorization checks, input validation, replay risks, callback forgery, and rate limiting across all NRS-facing endpoints.
### 2. Integration Architecture Review
Trust boundaries, data flows, token handling, secrets management, and segregation between your application and the revenue service.
### 3. Infrastructure & Cloud Hardening
Hosting environment, IAM, network exposure, container and workload security, and logging coverage for the integration stack.
### 4. Access Control & Session Testing
Role-based access, admin panels, session lifecycle, and privilege escalation paths that could let one client or tenant see another's data.
### 5. Data Protection & Transport Validation
Encryption in transit and at rest, key management, PII/taxpayer data handling, and alignment with NDPA 2023 principles.
### 6. Compliance Mapping
Findings mapped to NDPA 2023, CBN risk-based cybersecurity framework, and international standards such as ISO 27001 and SOC 2 where relevant.
## Who Needs This Assessment?
- **System Integrators** building NRS integration solutions
- **Access Point Providers** submitting or collecting revenue data
- **Pension administrators** and employers using NRS integrations
- **Any organization** required to demonstrate independent security assurance for revenue-data systems
## How to Prepare
1. **Define the integration scope** — Identify all APIs, webhooks, web applications, mobile apps, and infrastructure components involved.
2. **Provide staging or test credentials** — Where live testing is restricted, a representative staging environment helps maximize coverage safely.
3. **List restrictions and out-of-scope items** — Clearly define what cannot be tested and any time windows for testing.
4. **Assign a technical point of contact** — A knowledgeable engineer speeds up scoping and remediation.
5. **Plan for remediation** — Budget time to fix findings and request the included retest.
## What You Receive
Every engagement includes:
- Executive summary for leadership and regulators
- Technical report with CVSS 3.1-scored findings and reproduction steps
- Remediation roadmap with owner assignments
- Free retest of remediated findings
- Confidential attestation letter for prospects or regulators
## Conclusion
An NRS Integration Security Assessment gives certified integrators and their customers confidence that revenue data is protected by design, not by assumption. It turns a compliance checkbox into a real security outcome.
