A security device, according to various aspects of the present invention, secures an area accessible through a portal (e.g., doorway, window opening, hatch, vent) against unreported ingress or egress (e.g., access). A security device monitors a portal or a portal cover (e.g., door, window, screen, flap) to provide reports of access; a warning of unauthorized access; authentication of authorized users; and status of the security device.
