The Cybersecurity and Infrastructure Security Agency (CISA) is an operational component of the Department of Homeland Security (DHS). CISA works to understand, manage, and mitigate risk to the nation's cyber and physical infrastructure in the public and private sector. By working with our partners, we defend against today's threats and collaborate to build secure and resilient infrastructure for the future. CISA, which serves as the Sector Risk Management Agency (SRMA) for the Dams Sector, works collaboratively with sector partners to develop guidance, resources, and training that support the security and resilience of our nation’s dams, levees, navigation locks, and other water control facilities.
