Vigipirate

[1][2][3][4][5][6] Created in 1978 through interministerial sessions and falling within the responsibilities of the prime minister, it has since been updated three times: in 1995 (following a terror bombing campaign), 2000 and 2004.

[citation needed] Until 2014 the system defined four levels of threats represented by five colors: white, yellow, orange, red, scarlet.

The levels called for specific security measures, including increased police or police/military mixed patrols in subways, train stations and other vulnerable locations.
