    摘要： In one example, a firewall obtains a first network packet that indicates a first mobile country code of a mobile subscriber at a first time and a first mobile network code of the mobile subscriber at the first time. The firewall obtains a second network packet that indicates a second mobile country code of the mobile subscriber at a second time and a second mobile network code of the mobile subscriber at the second time. The firewall determines whether the first mobile country code is different from the second mobile country code or the first mobile network code is different from the second mobile network code. If so, the firewall determines whether a difference between the second time and the first time is less than a threshold difference. If so, the firewall associates the second network packet with a potential security threat.

    摘要： A device and method for locally authenticating an accessor device to access an operable device. The method comprises receiving reservation information at a validation device from an access granting device, the reservation information identifying one or more accessor devices as having permission to utilize the operable device, where the operable device is local to (e.g., within a predetermined proximity) of the validation device. The method further comprises receiving a request from an accessor device requesting permission to utilize the operable device, the request including an identifier of the requesting accessor device, validating the request based on the reservation information and the identifier, and when validation is successful, granting to the requesting accessor device permission to utilize the operable device. The method may further include receiving an instruction from the access granting device to revoke such permission from the requesting accessor device, and revoking such permission from the requesting accessor device.

    摘要： A Time-based One-Time Password (TOTP) validator is interposed between a principal and a network service. The validator interacts with a mobile application (app) on the mobile device associated with the principal to dynamically supply a validator secret. The secret and, perhaps, other information are processed by the app to generate a TOTP when the principal attempts to access a protected resource of the network service. The validator independently generates the TOTP and compares the app generated TOTP, and on a successful match, a principal's access device is redirected for access to the protected resource.
