WONOSIKOU, Mohadapwa HunnounguCovenant University Dissertation2025-10-072025-08https://repository.covenantuniversity.edu.ng/handle/123456789/50431Nigeria officially ventured into protecting its cyberspace in 2001 and has enacted its National Cybersecurity Policy and Strategy alongside legislative instruments such as the Cybercrimes Act 2015 and the National Data Protection Regulation 2019, to safeguard more than 103 million Internet users. Nonetheless, ongoing debates highlight that these measures may encroach upon fundamental freedoms, underscoring the complex task of balancing national security with individual rights. This study examined the implications of Nigeria’s National Cybersecurity Policy and Strategy and accompanying legislation on the digital rights of its citizens. Grounded in Buzan and Wæver’s Theory of Securitisation, this exploratory research employed a mixed-methods of data collection. A purposive and snowball sample of fifteen stakeholders, including journalists, activists, lawyers, and cybersecurity experts, participated in semi-structured interviews, complemented by document reviews of key policy texts. Thematic analysis was used to organise and categorise emergent themes systematically. Findings revealed that although the national cybersecurity policy and related laws were intended to strengthen data security, their implementation has expanded state surveillance capacities while eroding substantive privacy protections. Cybersecurity provisions have been instrumentalised to legitimise content removals and platform shutdowns, producing a chilling effect on public discourse. Furthermore, rather than explicit legal prohibitions, citizens primarily confront significant implementation gaps and infrastructural barriers that impede equitable Internet access. By presenting a comprehensive empirical study of Nigeria’s cybersecurity framework in a developing-country context, this research provided a unique insight into the security-privacy nexus and the operationalization of securitising discourse. In response, this study proposed, among other recommendations, harmonising policy with international human-rights standards; establishing a robust, independent oversight mechanism; and mandate transparency; and launching sustained digital-rights awareness. This study concluded that aligning Nigeria’s cybersecurity objectives with rigorous rights protections is essential to safeguarding national security while upholding the digital freedoms of all citizens.enCitizens’ RightsCybercrimeCybersecurityDigital RightsNational Cybersecurity Policy and StrategyNigeriaSecuritisation TheoryThesis
