    Abstract: Location-based, context-aware challenge-response authentication may be provided. First, a challenge may be provided to a user. The challenge may be based on a context corresponding to the user. The context corresponding to the user may comprise a location of a device associated with the user within an environment. Next, in response to providing the challenge, a response to the challenge may be received from the user. Then, in response to receiving the response to the challenge, it may be determined that the response is a correct answer to the challenge. In response to determining the response is the correct answer, a privilege may be provided to the user.

    Abstract: Various implementations disclosed herein enable controlling access to networks. In various implementations, a method of controlling access to a network is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes obtaining an indication that a mobile device having access to a first network utilizing a first radio access technology (RAT) has requested access to a second network utilizing a second RAT. In some implementations, the method includes determining whether the access to the first network satisfies an authentication criterion associated with the second network. In some implementations, the method includes granting the mobile device access to the second network in response to determining that the access to the first network satisfies the authentication criterion associated with the second network. In some implementations, accessing the second network via the authentication criterion satisfies an operating threshold associated with the mobile device.

    Abstract: The disclosed technology relates to systems and methods for automatically scaling down network resources, such as servers or gateway instances, based on predetermined thresholds. A system is configured to detect a reduction in one or more network metrics related to a first server, and instruct the first server to issue a rekey request to a plurality of devices connected to the first server. The system is further configured to instruct a load balancer to route to at least one other server responses from the plurality of devices to the rekey request, and determine a number of connections remaining between the first server and the plurality of devices. The system may be further configured to instruct the load balancer to terminate the first server based on the detected number of connections remaining between the first server and the plurality of devices.
