A security system for a storage container including a latch assembly disposed on an interior side of a door for latching the door in a closed position with the storage container. A plurality of reciprocating latch elements are included in the latch assembly for latching the door in a closed position with the storage container. A latch actuator included in the latch assembly moves the latch elements to latch the door. A master lock assembly controls operation of the latch actuator by having a first locking part of the master lock assembly interlocking with a second locking part carried by an elongated shaft connected to an operator on the container exterior. A tamper-resistant control blocks access to the master lock assembly from outside the storage container whereby access to the container interior is prevented when the latch assembly is closed and the master lock assembly is in an engaged position.
