UNITED STATES DEPARTMENT OF HOMELAND SECURITY (DHS) The Department of Homeland Security's (NHS) mission is to protect the United States from a variety of threats including (but not limited to) counter-terrorism and cyber security. One area where cyber security concerns and anti-terrorism overlap is in the protection of chemical facilities, which are regulated under the Chemical Facilities Anti-Terrorism Standards (CFATSs). CFATS includes a wide range of security controls, which can be measured against a set of Risk-Based Performance Standards (RBPSs). Chemical Facilities Anti-Terrorism Standard The Chemical Facility Anti-Terrorism Standards (CFATSs) are published by the United States Department of Homeland Security, and they encompass many areas of chemical manufacturing, distribution and use including cyber security concerns. More information on CFATS can be found on the DHS's website at: http://www. dhs.gov/files/laws/gc_1166796969417.shtm. CFATS Risk-Based Performance Standards The United States Department of Homeland Security also publishes recommen- dations in the form of Risk-Based Performance Standards (RBPSs) for CFATS.
