Subtitle III, reference (b), 44 U.S.C § 3554, SECNAVINST 5239.C, and DON CIO memorandum “Designation of the Department of the Navy Senior Information Security Officer” of 4 May 2020, Deputy Commandant for Information (DC I), Director, Information Command, Control, Communications, and Computers (IC4) is designated as Department of the Navy Deputy Senior Information Security Officer (Marine Corps) (DON Deputy SISO (Marine Corps)). Under the direction of the SISO, Information Compliance Branch (IC4/ICC) Cybersecurity section (CY) issues Marine Corps Enterprise Cybersecurity Manuals (ECSMs) that provide modules to guide the implementation of policy direction established in Marine Corps Order (MCO) 5239.2B, reference (c). The manuals provide procedural, technical, administrative, and supplemental guidance for all information systems used in the automated acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or receipt of data within the Marine Corps Enterprise Network (MCEN) as well as other Marine Corps information systems.

Each manual focuses on a distinct subject and describes a standard methodology for planning, implementing, and executing an element of Marine Corps Cybersecurity. The Marine Corps ECSM series is an authoritative source for implementation of cybersecurity policy direction.
