The First Order Security Bureau was developed for Marvel's Poe Dameron comics series and was first mentioned in issue #3.
Agent Tierny wears a band around her arm with Aurebesh letters that translate as "FOSB". This stands for "First Order Security Bureau."
The Aurebesh text on the data pad Tierny shows Tam translates to: Service Record Kazuda Xiono; family: Hamato Xiono; last known origin; Hosnian Prime; rank: pilot; occupation: New Republic Navy; (partially obscured)ncy: recruited to serve in the resistance.
The flashing letters in Aurebesh that appear on screen when Kaz is explaining his plan to sink the Colossus translate to 'Danger'.
