This study examines the protection of critical infrastructure in Liberia’s digital security environment, using the US$19.2 million cocaine seizure at Roberts International Airport (RIA) and the subsequent CCTV footage controversy as a focal case. The study examines the national security implications of vulnerabilities in surveillance systems, digital information governance, and institutional safeguards within Liberia’s critical infrastructure architecture. Guided by Securitization Theory and critical infrastructure protection frameworks, the study analyzes how surveillance governance, legal arrangements, institutional coordination, and information control influence national security outcomes in the context of transnational organized crime. Methodologically, the study adopts a qualitative case study design based on document analysis of official statements, legal and policy documents, media reports, and scholarly literature to examine the security, governance, and institutional dimensions of the incident. Findings reveal that RIA represents a high-value critical infrastructure asset exposed not only to external threats from transnational criminal networks but also to internal vulnerabilities involving surveillance governance, information management, and institutional coordination. The analysis demonstrates that the circulation of CCTV footage generated concerns regarding digital evidence integrity, investigative confidentiality, cybersecurity governance, and the protection of sensitive operational information. The study further finds that the controversy reflected securitization dynamics in which perceived surveillance vulnerabilities were constructed as broader national security concerns, resulting in increased scrutiny of institutional resilience and governance capacity. The study concludes that Liberia’s emerging cybersecurity and digital evidence framework should be strengthened through a comprehensive critical infrastructure protection strategy, sector-specific surveillance governance standards, improved inter-agency coordination, and enhanced cybersecurity controls for critical information systems. These measures are essential for strengthening national security resilience, protecting strategic infrastructure, and sustaining public trust in the digital age.
