US08001610B1 Network defense system utilizing endpoint health indicators and user identity
An endpoint defense system uses endpoint health indicators and user identity information to provide fine-grain access control over network resources. For example, the endpoint defense system may include a controller, a set of protection devices, and a set of agents. The agents are software applications installed on a set of endpoints to gather the health information that represents security states of the endpoint devices. The agents send updated health information to the controller. In response to a login attempt, the controller processes the health indicators and identity information through a set of administrator-defined policies to generate a set of access rights. The controller transfers the set of access rights to the protection devices. The protection devices then control user access to network resources according to the set of access rights. The controller sends updated sets of access rights to the protection devices whenever the access rights change.
US08001605B2 Method and system for detecting a communication problem in a computer network
A computer in a network runs a verification procedure in which it sends data packets to another computer in the network.

The computer then makes a determination regarding the network links between it and the other computer. If, for example, the other computer is able to respond by providing the secret piece of information back, then the computer sending the data packets concludes that the devices along the network links en route to the other computer are properly forwarding data packets.
US08001601B2 Method and apparatus for large-scale automated distributed denial of service attack detection
A multi-staged framework for detecting and diagnosing Denial of Service attacks is disclosed in which a low-cost anomaly detection mechanism is first used to collect coarse data, such as may be obtained from Simple Network Management Protocol (SNMP) data flows. Such data is analyzed to detect volume anomalies that could possibly be indicative of a DDoS attack. If such an anomaly is suspected, incident reports are then generated and used to trigger the collection and analysis of fine grained data, such as that available in Netflow data flows. Both types of collection and analysis are illustratively conducted at edge routers within the service provider network that interface customers and customer networks to the service provider. Once records of the more detailed information have been retrieved, they are examined to determine whether the anomaly represents a distributed denial of service attack, at which point an alarm is generated.

US08001547B2 Logic for synchronizing multiple tasks at multiple locations in an instruction stream
Logic (also called “synchronizing logic”) in a co-processor (that provides an interface to memory) receives a signal (called a “declaration”) from each of a number of tasks, based on an initial determination of one or more paths (also called “code paths”) in an instruction stream (e.g. originating from a high-level software program or from low-level microcode) that a task is likely to follow. Once a task (also called “disabled” task) declares its lack of a future need to access a shared data, the synchronizing logic allows that shared data to be accessed by other tasks (also called “needy” tasks) that have indicated their need to access the same. Moreover, the synchronizing logic also allows the shared data to be accessed by the other needy tasks on completion of access of the shared data by a current task (assuming the current task was also a needy task).

US08001515B2 Simultaneous optimization of analog design parameters using a cost function of responses
An analog system consists of a multitude of interconnected components. Design of such a system involves optimization of the component parameters to achieve a target behavior, collectively called specification. The present invention provides a generic cost function for analog design optimization. It also provides cost surface modeling to speed up the optimization.

US08001442B2 Data-processing system for measurement devices
The present invention provides a data-processing system for measurement devices, which performs a step-by-step sequence of data-processing tasks. In a conventional data-processing system, a failure in one data-processing task also causes the subsequent tasks to be unsuccessful. In such a case, the conventional data-processing system indicates the result of each unsuccessful task or the final result of the analysis by displaying only a blank or a specific character (e.g. the digit “0”). From such simple information, users cannot immediately identify the cause of the error. In contrast, in the data-processing system according to the present invention, if a data-processing task has been incorrectly performed for some reason, an error detector detects the error, and an error investigator identifies the cause of the error. Then, an error message displayer prepares an error message indicating the reason why the data-processing task concerned was unsuccessful and then displays the error message as the result of each of the aforementioned task and the subsequent tasks. The user can immediately learn the cause of the error by checking the error message of any of the unsuccessful tasks. Thus, the problem can be identified and solved in a shorter period of time.
