Answer:
The Department of Homeland Security (DHS) works with all federal departments and agencies that are prone to risks from digital disruption. DHS ensures that they adopt common policies and best practices that can help them respond to and face such risks. It uses different tools to ensure that all federal departments and agencies have the benefits of cybersecurity.
National Cybersecurity Protection System (NCPS): DHS’s Network Security Deployment is a division that designs and maintains the NCPS to oversee the cybersecurity of federal departments and agencies. The NCPS is an integrated system of all the systems used by federal departments and agencies. It’s capable of detecting and preventing intrusions, sharing information, and analyzing data. An important technology that is part of the NCPS is the EINSTEIN system, which performs two important roles. First, it identifies and blocks cyber attacks. Second, it uses threat information gathered from one agency to protect all other government agencies.
Continuous Diagnostic Mitigation (CDM) program: The CDM program provides federal departments and agencies with the tools to identify cybersecurity risks on an ongoing basis. Through these tools, cybersecurity personnel are able to prioritize and resolve the most significant risks first.
National Cybersecurity and Communications Integration Center (NCCIC): This center functions around the clock to respond to and manage cybersecurity incidents. The NCCIC is a network of cyber and communication systems belonging to the federal government, intelligence agencies, and law enforcement bodies. The center shares information with the public and private sectors. Thus, all federal departments and agencies can better understand cybersecurity and be aware of threats, incidents, and mitigation measures.
The NCCIC consists of a specialized team called the US Computer Emergency Readiness Team (US-CERT). The team is responsible for developing informational content for distribution to various federal departments and agencies, state and local governments, international organizations, and private sector organizations. US-CERT is also responsible for operating the NCPS.
