The Homeland Security Appointment Debate: Why Nigeria Must Avoid Institutional Overlap

By Damilola Ajasa

The appointment of a Special Adviser on Homeland Security by President Bola Ahmed Tinubu has generated significant public debate. While every government has the right to innovate and strengthen its security architecture, it is equally important to ask whether new structures genuinely address institutional gaps or merely duplicate responsibilities already assigned to existing agencies.

This conversation requires nuance rather than sentiment. The issue is not whether homeland security itself is important. It unquestionably is. Modern states must protect borders, critical infrastructure, cyberspace, public safety systems, immigration frameworks, and emergency response capabilities from increasingly complex threats. The real question is whether Nigeria currently lacks institutional structures to perform these responsibilities.

On balance, the answer appears to be no.

Nigeria already possesses an expansive domestic security architecture. The Ministry of Interior oversees immigration, correctional services, civil defence, and fire services. The Department of State Services (DSS) retains primary responsibility for internal intelligence and domestic security. The Office of the National Security Adviser (ONSA) coordinates national security strategy and inter-agency collaboration, while the National Counter Terrorism Centre (NCTC) already exists as a specialised multi-agency coordination platform for terrorism and emerging threats.

Against this backdrop, the creation of another homeland security advisory office risks creating institutional duplication rather than institutional efficiency.

Globally, homeland security structures are typically established to consolidate fragmented domestic security functions under one umbrella. The United States Department of Homeland Security emerged after the September 11 attacks because border protection, customs, emergency management, aviation security, and infrastructure protection were spread across disconnected agencies with weak coordination mechanisms. The reform was therefore structural and operational, not merely advisory.

Nigeria’s situation is fundamentally different. Most homeland security-related responsibilities already exist within established institutions. Border management sits with Immigration and Customs. Domestic intelligence belongs to the DSS. Emergency management is coordinated through NEMA. Critical infrastructure protection increasingly falls within the mandates of agencies such as NSCDC, NITDA, and the National Cybersecurity Coordination Centre. Counterterrorism coordination is already anchored at the NCTC under ONSA.

This is why concerns over institutional overlap should not be dismissed lightly.

If not carefully defined, the office of Special Adviser on Homeland Security could unintentionally usurp or blur the statutory responsibilities of the Ministry of Interior and the DSS. That outcome would be counterproductive. Security institutions function best when mandates are clear, disciplined, and respected. Once multiple offices begin competing over internal security coordination, intelligence reporting, or domestic operational oversight, friction inevitably emerges.

Nigeria’s security challenge has rarely been the absence of institutions. More often, it has been weak coordination, bureaucratic competition, duplication of mandates, and inconsistent implementation. Creating additional layers without addressing these underlying problems risks adding complexity rather than clarity.

This concern becomes even more important in the intelligence space. The DSS already maintains legal and operational responsibility for internal intelligence collection, counter-subversion, and domestic threat monitoring. Any attempt to create a parallel homeland security structure with overlapping intelligence functions could generate avoidable institutional rivalry. Such overlaps must be carefully avoided in the national interest.

Similarly, the Ministry of Interior already performs many of the functions commonly associated with homeland security in other jurisdictions, including immigration oversight, civil protection, border governance, and internal administrative security coordination. Rather than creating potentially overlapping advisory structures, a stronger argument could have been made for strengthening the institutional capacity and coordination role of the Ministry itself.

None of this suggests that the government’s intention is misplaced. The threats confronting Nigeria are evolving rapidly. Cyberattacks, organised crime, infrastructure sabotage, disinformation campaigns, terrorism financing, irregular migration, and transnational criminal networks increasingly intersect in ways that traditional security models sometimes struggle to manage.

However, institutional expansion should not become a substitute for institutional reform.

The more sustainable approach would have been to strengthen existing structures, clarify inter-agency coordination frameworks, improve intelligence integration, modernise border governance systems, and deepen operational cooperation between existing agencies rather than introducing another office into an already crowded security ecosystem.

There is also a broader governance principle at stake. Mature security systems are built on clarity of responsibility. Citizens and institutions must know which agency is responsible for what function. Once roles become blurred, accountability weakens. In moments of crisis, confusion over mandates can delay response times, complicate intelligence sharing, and undermine operational effectiveness.

Nigeria’s security architecture therefore requires streamlining more than expansion.

The appointment of a Special Adviser on Homeland Security should consequently remain narrowly administrative and coordinative if it is to avoid institutional conflict. The office should not evolve into a parallel Ministry of Interior, a competing domestic intelligence platform, or an alternative counterterrorism coordination centre.

Ultimately, the success of Nigeria’s security architecture will depend less on the number of offices created and more on whether existing institutions are empowered, disciplined, coordinated, and properly led. The country does not suffer from a shortage of security structures. It suffers from fragmentation, overlap, and implementation gaps.

Those realities must remain central as Nigeria continues to reform its national security framework.
