You unlock the Security Armor in Halo 3 by getting Gamerscore in the game (ie: Unlock achievements). To get the Shoulder Armor, you will need to rack up a whopping 700-850 GS (it seems to vary for some reason).
Note: There is a known glitch in the game that will not allow players to unlock the Security Shoulders sometimes.
