FISMA, also known as Title III of the E-Government Act (Public Law 107-347), mandates that all U.S. federal agencies develop and implement an agency-wide information security program that explains its security requirements, security policies, security controls, and risks to the agency. The requirements, policies, controls, and risks are explained formally in a collection of documents known as a Certification Package. The Certification Package consists of a review and analysis of applications, systems, or a site basically whatever it is that the agency wants accredited.
