Enterprise Cybersecurity Manuals
Per 10 U.S.C. and 40 U.S.C. Subtitle III, the Director C4 designates the Marine Corps Senior Information Security Official (SISO), who issues Marine Corps Enterprise Cybersecurity Manuals (ECSMs). The ECSM series provides modules that guide the implementation of policy direction as stated in MCO 5239.2A, Marine Corps Cybersecurity Program (MCCSP), "provides cybersecurity policy, procedures, tasks, conditions, and standards implementation guidance applicable to enhance and enable command and control on the MCEN."
The modules provide procedural, technical, administrative and supplemental guidance for all information systems used in the automatic 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 module focuses on a distinct subject and describes a standard methodology for planning, implementing and executing an element of the MCCSP. The Marine Corps ECSM series will be the authoritative source for implementation of cybersecurity policy direction.
