Full alert
Full alert was a state of tactical readiness. 

Captain James T. Kirk called a full alert in 2267 when, following an apparent invitation to the Federation colony on Cestus III from Starfleet Commodore Travers, Kirk's landing party beamed down to find the colony site already destroyed. ()

In 2371, Captain Kathryn Janeway gave an order to have all security stations at full alert following the first contact with the Numiri. ()
