Abstract: An apparatus in one embodiment comprises a processing platform that includes one or more processing devices each comprising a processor coupled to a memory. The processing platform is associated with at least one storage device. The processing platform comprises a backend data classifier configured for communication with a data loss prevention system. The backend data classifier comprises a file analyzer configured to compare characteristics relating to current states of respective files stored in the storage device with information stored in a file history database, and an assignment module configured to assign classifications to respective ones of the files stored in the storage device based at least in part on comparison results from the file analyzer. The data loss prevention system is configured to perform different data loss prevention operations on different ones of the files stored in the storage device based at least in part on their respective assigned classifications.

Abstract: An apparatus in one embodiment comprises a security appliance having a processor coupled to a memory. The security appliance is associated with at least one storage device and comprises a ransomware detector configured to generate a detection score for one or more sets of files stored in the storage device. The ransomware detector comprises a file analyzer configured to compare characteristics relating to a current state of the files with information stored in a file history database, and a detection score generator having a weighting module for applying weights to respective comparison results from the file analyzer in generating the detection score for the one or more sets of files. The ransomware detector is further configured to generate an alert if the detection score for the one or more sets of files exceeds a specified threshold. The alert may be transmitted by the security appliance to a network security system.

Abstract: The present invention is a tilt switch that opens or closes an electrical circuit in accordance with the angle of inclination of the switch. The present invention switch includes a housing that defines a hollow cavity. A first sphere, having a highly conductive circumferential surface, is positioned within the hollow cavity. As the switch is inclined, the first sphere rolls to one end of the housing where the sphere contacts an electrical connector. The first sphere electrically interconnects the electrical connector to the housing on which the sphere rests, thereby completing an electrical connection between the electrical connector and the conductive material of the housing. At least one second sphere is also positioned within the housing. The second sphere is sized in relation to the hollow cavity so that the first sphere cannot pass by the second sphere within the cavity. As the switch is inclined, the first sphere rolls against the electrical connector, closing the switch.

Abstract: A tilt switch having at least one conductive weight held within an inert atmosphere within a housing. The weight being free moving within the housing, moving from one end of the housing to the other as the angle of inclination of the housing is changed. At one end of the housing are positioned the contact points of at least two terminals. As the weight abuts against the terminals, electricity is conducted through the weight from one terminal to the other; thus completing a circuit. The terminals may be shaped, or the number of conductive weights increased, to increase the area of contact between the weights and the terminals. The increased surface area results in a more reliable tilt switch that has increased performance characteristics and a higher power capacity.
