| 20100095017 | SCALABLE AND DYNAMIC QUALITY OF SERVICE CONTROL - Applications and users dynamically make QoS provisioning requests for individual traffic flows traversing client and server hosts. A traffic flow provisioning request is conveyed to a services manager, which determines a set of traffic attributes for the flow and determines the networks the flow traverses between the client and server hosts. The services manger then oversees the admission of the flow to appropriate traffic classes in each determined network and the obtaining of a DSCP value for each network. Lastly, the services manger conveys the DSCP value of the first network traversed back to the client or server host, depending on the direction of the flow, which host is then configured to appropriately mark the DSCP field of the traffic flow packets. In a further embodiment, the services manager also instructs the client or server host to perform packet policing and shaping for the flow. | 04-15-2010 |

| 20080209578 | Protecting system management mode (SMM) spaces against cache attacks - A computing system may comprise a processor and a memory controller hub coupled by an external bus such as the front side bus. The processor may also comprise a cache. The processor may operate in SMM and the memory coupled to the memory controller hub may comprise SMM spaces such as compatible, HSEG, and TSEG areas. A software-based attack may write malicious instructions into the cache at an address corresponding to the SMM spaces. The illegal processor memory accesses that occur entirely inside the processor caches due to the cache attack may be forced to occur on the external bus. The memory controller hub may be capable of handling the memory accesses occurring on the external bus thus, protecting the SMM spaces against cache attack. | 08-28-2008 |
| 20120072734 | PLATFORM FIRMWARE ARMORING TECHNOLOGY - A method, apparatus, method, machine-readable medium, and system are disclosed. In one embodiment the method includes is a processor. The processor includes switching a platform firmware update mechanism located in a computer platform to a platform firmware armoring technology (PFAT) mode on a boot of the computer platform. The computer platform includes a platform firmware storage location that stores a platform firmware. The method then persistently locks the platform firmware storage location in response to the platform firmware update mechanism switching to the PFAT mode. When persistently locked, writes are only allowed to the platform firmware storage location by an Authenticated Code Module in the running platform and only after a platform firmware update mechanism unlocking procedure. | 03-22-2012 |

| 20120123097 | RICIN A CHAIN MUTANTS LACKING ENZYMATIC ACTIVITY AS VACCINES TO PROTECT AGAINST AEROSOLIZED RICIN - The present invention provides methods to produce toxoid vaccines, such as ricin A chain vaccines, with reduced ability to promote vascular leak syndrome (VLS) and catalytic toxicity associated with various proteinaceous toxins, such as ribosome inactivating proteins. The invention also provides toxoids which have been mutated to lack amino acid sequences which induce VLS and toxic catalytic activity. | 05-17-2012 |
