Abstract: Techniques for (i) using contextual information associated with an exposed credential to identify a resource that could be accessed using the exposed credential, (ii) identifying a responsible entity of that resource, and (iii) alerting the responsible entity about the exposed credential are disclosed. A credential is determined to be in an exposed state. The exposed credential, if used, could potentially provide an actor access to a resource, despite the fact that the actor should not have access to the resource. The exposed credential is analyzed to determine a context. Based on that context, the resource is identified. A responsible entity associated with the resource is identified. An alert is then sent to that entity.

Abstract: A corrugated armoring layer for a communication cable is primarily formed of an elongated strip of metal or alloy, e.g., steel, having a first side and an opposite, second side. The armoring layer is wrapped around a cable core so that first and second side edges come to abut, or slightly overlap, and then are welded either continuously or intermittently to form a seam. In the case of intermittent welding, it is preferred that only the tops or outward-facing ridges of the corrugations are welded, such as every top corrugation or every other top corrugation is welded. A conductive adhesive tape may be applied along the seam as well, if additional environmental sealing and/or electrical shielding is desired.
