The article presents a study in the area of critical infrastructure protection based on the fact that maritime areas include critical assets which functionality appears to be very important in the modern security environment. The objective of the study is to recognise such seabed critical infrastructures in the scope of Bulgarian territorial waters and to analyse their security having legal, procedural, and technological considerations for the security system and identifying the rapidly evolving threats in the Black Sea region.
The article is structured in the same logical way, resulting in multifactor analysis and classification. The main findings are based on the understanding that critical infrastructures resilience is achieved by continuity of operation and their physical security, and both of them can be controlled properly by applying a risk management approach in line with the national particularities. The specifics in the maritime domain determine a specific security environment that can be used successfully for offensive and defensive actions.
