Abstract: A security system collects an audit trail on a computer outside of a boundary created by one or more virtual machines. The security system uses a privileged virtual machine to collect audit logs for each protected virtual machine. As the protected virtual machines run, they send auditing information to the privileged virtual machine. The privileged virtual machine can collect auditing information from protected virtual machines much more quickly than a network server, as well as collecting auditing events from multiple protected virtual machines. Because the auditing destination is located on the same computer as the virtual machine monitored by the audit trail, no network dependency is present. Thus, the security system allows for monitoring the activity of administrators and other users while preventing tampering with the audit trail of each user's actions.

Abstract: Implementing a unified communication system allowing different clients to communicate using different communication modalities to access the same functionality of a remote application. A method includes identifying functionality of an application of a service. The method further includes determining a plurality of communication modalities that can be used to access the functionality of the application of the service by identifying communication modalities identified by a developer as being communication modalities that can be used to access the functionality of the application of the service. The method further includes, based on identifying a plurality of communication modalities that can be used to access the functionality of the application of the service, determining that the functionality of the application is supported by a unified communication function. The method further includes at runtime mapping operation of the plurality of communication modalities to the unified communication function.
