This study explored the general problem of the cyber-terrorism threat to Sub-Saharan telecommunications networks. Terrorist organizations pose a threat to Cameroon's telecommunications critical infrastructure. The study contributes to the overall good of Cameroon's critical infrastructure protection plan by helping to better understand the terrorist threat considered in the study. A qualitative case-study design together with the Generic Threat Matrix and the Cyber Threat Intelligence frameworks were used to qualitatively measure the threat and its attributes. Telecommunications officials, security officials, information technology professionals, and civil society leaders were interviewed for data collection. Findings revealed that Boko Haram has a high-level of commitment threat attribute, but low-to-moderate resources attribute. In addition, the protection of interconnected critical infrastructures and cyber-security in Cameroon is challenged by the lack of resources, laws, policies, and awareness of existing threats. Recommendations for future studies and practice include classifying elements that influence the characterization of a threat attribute like cultural considerations, categorization of other threats on Cameroon's telecommunications critical infrastructure and determining sources of compromise. Finally looking at the government as a state actor being responsible for multiple internet shut downs for political reasons which brought hardship to the population.
