DHS/CISA/PIA-026 National Cybersecurity Protection System (NCPS)
The National Cybersecurity Protection System (NCPS) is an integrated system for intrusion detection, analysis, intrusion prevention, and information sharing capabilities that are used to defend the federal civilian government’s information technology infrastructure from cyber threats. The NCPS includes the hardware, software, supporting processes, training, and services that are developed and acquired to support its mission. The Department of Homeland Security (DHS), Cybersecurity and Infrastructure Security Agency (CISA), National Cyber Security Division (NCSD) is conducting this Privacy Impact Assessment (PIA) because personally identifiable information (PII) may be collected by the NCPS, or through submissions of known or suspected cyber threats received by the United States–Computer Emergency Readiness Team (US-CERT) for analysis. This PIA will serve as a replacement for previously published PIAs submitted by NSCD for the 24/7 Incident Handling Center (March 29, 2007), and the Malware Lab Network (May 4, 2010), and is a program-focused PIA to better characterize the efforts of NCPS and US-CERT.

DHS/CISA/PIA-029 Automated Indicator Sharing
The Department of Homeland Security (DHS) National Protection and Programs Directorate’s (NPPD) Office of Cybersecurity and Communications (CS&C) has developed an Automated Indicator Sharing (AIS) initiative to enable the timely exchange of cyber threat indicators and defensive measures among federal and non-federal entities. These cyber threat indicators and defensive measures are shared consistent with the need to protect information systems from cybersecurity threats, mitigate cybersecurity threats, and comply with any other applicable provisions of law authorized by the Cybersecurity Information Sharing Act of 2015 (CISA) in a manner that ensures appropriate incorporation of privacy, civil liberties, and other compliance protections. Central to the AIS initiative and consistent with the requirements of CISA, the DHS National Cybersecurity and Communications Integration Center (NCCIC) serves as the centralized hub for exchanging cybersecurity threat information using a DHS-accredited infrastructure. NPPD is conducting this Privacy Impact Assessment (PIA) because personally identifiable information (PII) may be submitted as part of or accompanying a cyber threat indicator or defensive measure. This PIA updates and retires DHS/NPPD/PIA-029 Automated Indicator Sharing PIA, issued October 28, 2015.
