Abstract: Apparatuses, methods, systems, and program products are disclosed for baseline network dependency mapping and alerting. An apparatus includes an asset module that identifies a plurality of network assets of a data network, a dependency module that determines dependencies between the plurality of network assets across different physical and virtual layers within the data network, and a baseline module that generates a snapshot of the plurality of network assets and the dependencies between the plurality of network assets across the different physical and virtual layers within the data network at a point in time.
