This research examined the activities of the Boko Haram sect and how it has impeded the national security, economic, political and social matrix of the Nigerian polity. The research argued that the insurgence of the sect would continually be a national security challenge in-spite of the marginal lip-service of the government to curb the heinous activity. The research relied more on secondary data-journals, magazines newspapers internet and the theoretical framework is frustration aggression and relative deprivation theories. The research concluded that development cannot take place in an atmosphere of insecurity made manifest on a daily basis in Nigeria such as poor governance, destruction of lives and properties, forced migration, lack of basic amenities. In view of this, the study maintained that there is the need for Nigeria to evolve and implement a clear, comprehensive and robust counter terrorism strategy that addresses the grievances and feelings of marginalization that extremist exploits in their recruitment drive, rationalization of their anti-secular ideologies and staging of violent attacks in Nigeria.
