Abstract: There is provided a security module for protecting circuit components from unauthorized access. The security module comprises a base printed circuit board, base PCB, for supporting circuit components to be protected, a frame printed circuit board, frame PCB, where the frame PCB is secured on top of the base PCB and defining a protective space for circuit components supported by the base PCB, and a lid printed circuit board, lid PCB, which is secured on top of the frame PCB, thereby providing a top closure to the protective space. First and third meshes are provided in the frame PCB, and a second mesh is provided in the lid PCB. The first, second and third meshes have a number of electrically conductive tracks, and one or more tamper detection paths are formed comprising a serial connection of one track from each of the first, second and third meshes. The security module may further comprise security circuitry arranged on the base PCB within the protective space, and for each tamper detection path the security circuitry has a pair of electrical signal input/outputs being electrically connected to the tamper detection path.
