摘 要：The Enhanced Cybersecurity Services (ECS) is a voluntary program based on the sharing of indicators of malicious cyber activity between Department of Homeland Security (DHS) and participating Commercial Service Providers. The purpose of the program is to assist the owners and operators of critical infrastructure to enhance the protection of their systems from unauthorized access, exploitation, or data exfiltration through a voluntary information sharing program. ECS consists of the operational processes and security oversight required to share unclassified and classified cyber threat indicators with companies that provide internet, network, and communication services to enable those companies to enhance their services to protect U.S. Critical Infrastructure entities. ECS is intended to support U.S. Critical Infrastructure, however, pending deployment of EINSTEIN intrusion prevention capabilities, ECS may also be used to provide equivalent protection to participating Federal civilian Executive Branch agencies. The National Protection and Programs Directorate (NPPD) is conducting this Privacy Impact Assessment (PIA) because personally identifiable information (PII) may be collected. This PIA consolidates and serves as a replacement to the DHS/NPPD/PIA-021 National Cyber Security Division Joint Cybersecurity Services Pilot PIA, published on January 13, 2012, and the DHS/NPPD/PIA-021(a) National Cyber Security Division Joint Cybersecurity Services Program (JCSP), Defense Industrial Base (DIB) Enhanced Cybersecurity Services (DECS) PIA Update, published on July 18, 2012.
