Cybersecurity and Infrastructure Security Agency (CISA)

Contributor(s): Matthew Haughn

Cybersecurity and Infrastructure Security Agency (CISA) is a division of the Department of Homeland Security (DHS) that is tasked with the defense of the infrastructure of the internet and the charge to design measures to improve the infrastructure’s resilience and security.

CISA is constantly identifying and assessing threats to infrastructure. The organization consults with government and private sector providing cybersecurity tools, threat analysis and incident response across all .gov websites.

CISA facilitates defenses and improvements by way of both private and public sector partnerships. Tools for technical coordination and assistance are delivered country-wide to partners in order to develop emergency communications. The organization concerns itself with threats to infrastructure from sources such as natural disaster, cyberwarfare, terrorist attack or other man-made threats.

Within the CISA is the National Risk Assessment Center. This internal group is assigned with the identification and analysis of the most serious threats to infrastructure. The group pays close attention to all threats that may impact those elements of the government and private sector that are deemed vital to societal function, or critical infrastructure.

CISA was created when President Donald Trump signed the Cybersecurity and Infrastructure Security Act of 2018 into law. While the CISA is under the oversight of the DHS, it is a standalone agency of the United States.
