TLDR
In this paper, a method and system for event publication and subscription with an event channel from user level and kernel level is described, which includes an event queue for an event sent by a publisher and a dispatcher for dispatching based on filtering criteria the event to the subscriber-based queue if the corresponding subscriber has subscribed to receive delivery of the event.Abstract:
A method and system for event publication and subscription with an event channel from user level and kernel level are disclosed. The system comprises an event channel. The event channel includes an event queue for an event sent by a publisher. Additionally, the event channel has a plurality of subscriber-based queues each corresponding to a subscriber. If the corresponding subscriber has subscribed to receive delivery of the event, the subscriber-based queue includes the event. Moreover, the event channel further comprises a dispatcher for dispatching based on filtering criteria the event to the subscriber-based queue if the corresponding subscriber has subscribed to receive delivery of the event, and a delivery mechanism for delivering the event from the subscriber-based queue to the corresponding subscriber. The publisher can be a user level publisher or a kernel level publisher. The subscriber can be a user level subscriber or a kernel level subscriber.read more

Secure virtualization system software
TL;DR: In this article, the authors present a method for intercepting an event in a kernel mode of the virtualization environment, suspending execution of the event, and transmitting the event to a user mode security module that determines whether the event should be blocked, allowed, or redirected.

Kernel event subscription and publication system and method
TL;DR: In this paper, an event subscription and publication system for dynamically notifying user level applications of kernel level events is presented. But the system does not provide the user application with specific information classifying the nature and details of the event, and it requires the user level application to interrupt the normal processing states to identify these events when they occur.

Signed manifest for run-time verification of software program identity and integrity
TL;DR: In this paper, a measurement engine computes a comparison value on the program's image in memory and determines if the comparison value matches the expected integrity check value, if the values do not match, the program image is determined to be modified, and appropriate remedial action can be triggered.

System and method for forward custom marshaling event filters
TL;DR: In this paper, the authors present an approach for reporting the occurrence of events in a computer system to event subscriber software, which is accomplished by custom forward marshaling a proxy to each event provider and at least one event-filtering definition that specifics which events should be reported by that event provider to the subscriber software.
