The Joint Cybersecurity Services Program (JCSP) is the Department of Homeland Security's voluntary information sharing initiative with the Department of Defense (DoD) and participating commercial companies. The purpose of the program is to enhance the cybersecurity of participating critical infrastructure entities through Information sharing partnerships with the critical infrastructure organization or their commercial service provider (CSP).
The first phase of the JCSP will focus on the cyber protection of the Defense Industrial Base companies that are participating in the DoD's Cyber Security/Information Assurance (CS/IA) program. This sub-program is known as the DIB Enhanced Cyber Security Service (DECS). The JCSP may also be used to provide equivalent protection to participating Federal civilian agencies pending deployment of EINSTEIN intrusion prevention capabilities.
