Abstract: According to an embodiment, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise determining that an endpoint device has requested to discover a location of a protected resource that is protected by a gateway, determining whether the endpoint device has provided a token that is valid, and permitting the endpoint device to discover the location of the protected resource based on determining that the endpoint device has provided the token that is valid. The token indicates that the endpoint device successfully completed a first multi-factor authentication procedure in connection with accessing an authentication enforcement resource.

Abstract: A personal server is provided for use with a mobile device, such as a cellular telephone. The personal server provides services to the user of the mobile device and to others authorized by the user, but to no other users. The personal server may be a home PC of the user of the mobile device. The personal server may serve as a proxy server for a shared server that provides services to the mobile device. The personal server may relay messages between the mobile device and the shared server. The personal server may store, log, filter, and perform other processing on the user's personal data, such as messages transmitted by the mobile device and/or the shared server. The personal server may aggregate messages received from a plurality of shared servers. A non-personal server may perform additional services, such as configuring the personal server and temporarily storing data if the personal server becomes inaccessible.

Abstract: When a caller requests access to a remote application server, a portal transfers an augmenting grammar set to the remote application server. The remote application server is connected to the caller and recognizes inputs by the caller. When an input is received which corresponds to the augmenting grammar set, the remote application server notifies the portal.
