Abstract: The disclosed computer-implemented method for managing computing device access to local area computer networks may include (i) receiving, at a router computing device, a request to connect a client computing device to a local area computer network, (ii) determining whether the client computing device has prior authorization to connect to the local area computer network, (iii) sending, when the client computing device is determined to not have prior authorization, a request to an administrator computing device for authorization to connect the client computing device to the local area computer network, (iv) receiving, from the administrator computing device, an instruction to allow the client computing device to connect or to block the client computing device from connecting, and (v) performing a security action to block or allow the client computing device's request based on the instruction. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for sharing data based on user ranking is described. In one embodiment, the method includes determining a location of a computing device, identifying a request to share data from the computing device with one or more other computing devices, and ranking potential recipients of the data from the computing device based on at least one of location data, network communication data, and contact information.

Abstract: A method for restarting a force stop mobile application is described. In one embodiment, the method may include establishing a connection with a first application installed on a mobile device and receiving a heartbeat signal from the first application via the established connection. Upon receiving the heartbeat signal, the method may include monitoring for subsequent heartbeat signals from the first application and determining a subsequent heartbeat from the first application is not received when expected. Upon determining the subsequent heartbeat from the first application is not received when expected, the method may include determining whether a second application related to the first application is running on the mobile device.

Abstract: A computer-implemented method for detecting private browsing mode may include (1) determining that a browser application is operating as a foreground application on the computing device, (2) detecting computing activity occurring on the computing device while the browser is operating in the foreground, (3) determining that no new entry has been made in the browser's history, (4) in response to determining that no new entry has been made in the browser's history, incrementing a certainty level score that identifies a level of certainty that the browser is executing in private browsing mode, (5) determining that the certainty level score has exceeded a certainty threshold, indicating that the browser is likely to be executing in private browsing mode, and (6) performing a security action in response to determining that the browser is likely to be executing in private browsing mode. Various other methods, systems, and computer-readable media are also disclosed.
