Abstract: A method, computer program product, and apparatus for presenting data about security-related events that puts the data into a concise form is disclosed. Events are abstracted into a set data-type. Sets with common elements are grouped together, and summaries of the groups—“situations” are established from groups whose severity exceeds a threshold value. These groups and situations are then propagated up a hierarchical arrangement of systems and further aggregated so as to provide summary information over a larger group of systems. This hierarchical scheme allows for scalability of the event correlation process across larger networks of systems.

Abstract: A method, computer program product, and apparatus for presenting data about security-related events that puts the data into a concise form is disclosed. Events are abstracted into a set data-type. Sets with common elements are grouped together, and summaries of the groups—“situations”—are presented to a user or administrator.

Abstract: The present invention is directed to an interceptor security server. The server receives incoming requests from a network and determines if they are valid or not. When the requests are valid, the server relays them to other computing devices that store the actual data. The other devices then relay the requested information to the server, which then passes it to the requesting party. When an invalid request is received, the server denies the request. In this manner, the server protects the associated other computing devices from harmful attacks, snooping requests, or other invalid network requests.

Abstract: An apparatus and method for authenticating users on a data processing system is implemented. The present invention provides for aggregating authenticated identities and related authorization information. A security context created in response to a first user logon is saved in response to a second logon. A composite or aggregate security context is created based on the identity passed in the second logon. Access may then be granted (or denied) based on the current, aggregated security context. Upon logout of the user based on the second identity, the aggregate security context is destroyed, and the security context reverts to the context previously saved.

Abstract: A novel internal combustion engine head assembly is disclosed wherein the rocker arms for the intake and exhaust valves each have a portion that pivots about a common axis, and wherein these portions are concentric to one another. Thus, a very compact combustion head assembly is provided. In particular, the present invention is useful in Harley-Davidson motorcycles.

Abstract: A method and apparatus for displaying a data collection within a data processing system, wherein the data collection includes a plurality of entries. First a control layer is displayed. Next, entries from the plurality of entries in the data collection are displayed within the control layer. In response to entries within the plurality of entries being undisplayed within the control layer, a secondary layer and entries from the additional entries from the plurality of entries are displayed within the secondary layer, wherein the data collection is efficiently displayed within the data processing system.
