Hospitals and Healthcare Facilities

Hospitals and healthcare facilities face a unique set of challenges in an active shooter incident. These incidents have no patterns in victim selection or method, creating an unpredictable and quickly evolving situation that can lead to loss of life and injury.

CISA Releases National Critical Functions Set

The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) today released the inaugural set of National Critical Functions.  These are functions used or supported by government and the private sector that are of such vital importance to the United States that their disruption, corruption, or dysfunction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof.

Supply Chain Risks for Information and Communication Technology

U.S. critical infrastructure relies on Information and Communications Technology (ICT)—defined by the National Institute of Standards and Technology as “the capture, storage, retrieval, processing, display, representation, presentation, organization, management, security, transfer, and interchange of data and information”—for daily operations and functionality. The Design, Development and Production, Distribution, Acquisition and Deployment, Maintenance, and Disposal phases of the ICT supply chain are susceptible to the malicious or inadvertent introduction of vulnerabilities such as malicious software and hardware; counterfeit components; and poor product designs, manufacturing processes, and maintenance procedures.

GPS Week Number Roll Over

An accurate accounting of time is of critical importance to nearly every modern organization. Because of its low cost and universal availability, The Global Positioning System (GPS) has become the standard time keeper for many commercial users across the globe.

Detection and Prevention

CISA rapidly notifies relevant critical infrastructure stakeholders of elevated risk exposure, conducts incident management operations, provides vulnerability assessments, and directly deploys risk management information, tools, and technical services to mitigate risk, including regulatory enforcement where authorized.
