The manufacturing, use, storage, and distribution of chemicals must be secured from threats including terrorism and accidents. Some chemical facilities possess materials that could be stolen and used to make weapons. A successful attack on certain high-risk facilities could cause a significant number of deaths and injuries. The impacts of an accident or attack are far-reaching and can occur in a variety of ways.
Violent extremist threats come from a range of groups and individuals, including domestic terrorists and homegrown violent extremists in the United States, as well as international terrorist groups like al-Qaeda and ISIL.

Secure driver's licenses and identification documents are a vital component of a holistic national security strategy.
Protecting the United States from terrorism is the founding mission of DHS. While America is stronger and more resilient as a result of a strengthened homeland security enterprise, terrorist threats persist and continue to evolve.
