Summary

Gives plain meanings for key words used here. "Agency" means what section 551 of title 5 says. "Covered Federal agency" means the Department of Homeland Security. "Critical infrastructure information" means what section 650 of this title says. "Critical infrastructure protection program" means any part of a covered agency that the President or an agency head names to receive critical infrastructure information. "Protected system" means any service, physical or computer system, process, or procedure that directly or indirectly affects whether a critical infrastructure facility can work, and it includes computers, networks, hardware, software, and data no matter how stored or sent. "Voluntary" means information sent when the agency has no legal power to force it. It can come from one entity or from an Information Sharing and Analysis Organization for its members. But "voluntary" does not cover information filed under the securities laws (see section 78c(a)(47) of title 15) with the SEC or federal banking regulators under section 78l(i) of title 15, disclosures made with an offer or sale of securities, or information used for licensing, permitting, or other regulatory proceedings.
