A secure enclosure prevents access to both the front and rear of the rack mounted equipment through the use of fabricated sheet metal enclosures with hinged access covers, uniquely attached to the rack faces from the inside. Access is granted to a front swing cover only by presenting proper credentials typically in the form of a card key to an electronic card reader which opens the electronic latch or strike. A back swing cover panel is secured from the inside with a latch and can be opened after gaining proper access through the front.
