WASHINGTON - Homeland Security Secretary Kirstjen (KEER’-sten) Nielsen says her Cabinet agency may have been founded to battle terrorism, but its mission is shifting, especially to guard against emerging threats online. Nielsen says in a speech that there must be a defence that includes everyone, not just the government, because Americans’ devices and networks are being threatened. She says countries such as China and Iran are mimicking tactics used by Russia to disrupt U.S. systems.
