The layered, three-tier system of agencies guarding India's coastline and maritime zones, reorganised after the 26 November 2008 Mumbai attacks, which were carried out by terrorists arriving by sea.
Coastal security is one of the most tested internal-security themes after 2008; the three-tier model, the lead agency in each zone, and the coastline length are high-value facts.
Match the zone to the agency: Marine Police (near shore), Coast Guard (territorial waters, lead for coastal security), Navy (overall maritime). Do not confuse the Coast Guard (Ministry of Defence) with the MHA's Coastal Security Scheme that funds State coastal police.
