Abstract: A computer receives a request for protected user data with an access token presented by a client as authorization for the client to access the protected user data in a delegated environment. The computer parses the request to create a device fingerprint identifying the device submitting the request for the client. The computer compares the device fingerprint of the request to a previously stored device fingerprint of an authorized device associated with the access token. The computer automatically determines whether to identify the access token as potentially misappropriated based on the comparison of the device fingerprint of the request to the previously stored device fingerprint.

Abstract: In an ad hoc mesh network, roles are assignment to the different network nodes, for example mesh point or mesh portal. The invention envisages that a network node identifies the certification and thus the permitted roles of another network node before it sends a message to said other network node. This ensures that the roles maintain their integrity and the security in the network is enhanced.

Abstract: A system enables end user devices to receive audio announcements from third party cloud-based resources. For example, the system may include a first party cloud-based resource providing tokens to the third party cloud-based resource in order to prevent the third party cloud-based resource from causing audio announcements to be output by user devices without authorization. In some cases, the tokens may be time based and prevent the third party cloud-based resource from causing audio announcements to be output by user devices after a predefined amount of time. In other examples, the tokens may be use based and prevent the third party cloud-based resource from causing the user device to output more than a predetermined number of audio announcements.

An operating environment of the portable device may be established after executing the certified code.

Abstract: A method, system, and computer program product for providing protected remote access from a remote access client to a remote access server over a computer network through a plurality of inspections. A remote access configuration file is created for the remote access client. A digital hash of the configuration file is then generated. The digital hash is compared with a configuration file stored at a predefined web location. If the comparison results in a match between the digital hash and the stored configuration file, a digital hash comparison is performed between an encrypted remote access configuration file and an encrypted configuration file stored at the predefined web location. If the plurality of inspections are passed, the remote access client is released from a quarantine state and a virtual private network (VPN) connection to the remote access server is established.

Abstract: Some embodiments provide reconfigurable web application firewall (WAF) functionality across a distributed platform. Specifically, the WAF function at each distributed platform server is customizable on a per customer and per inbound message basis. When a server receives an inbound message, the server identities the content or services of which specific customer are implicated by the inbound message. The server screens the inbound message for attacks using a first set of rules and policies defined as part of a production profile from a WAF instance defined by the specific customer while contemporaneously testing the inbound message against a second set of rules and polices defined as part of an audit profile from the same WAF instance. In this manner, the specific customer tests the audit profile rules and policies while still receiving the protections of the production profile rules and policies.
