Dynamic Network Identity and Policy management
InactiveUS20070150934A1Network resource is limitedSpecial data processing applicationsSecurity arrangementTarget ResponsePassword
Network policies are managed based at least in-part on user / entity identity information with: a state monitor operable to monitor for state change events in user / entity state and related, network state or in traffic pattern and traffic flow state; an identity manager operable to obtain and validate user credentials; and a policy manager operable in response to a state change event detected by the state monitor (either the identity manager or a defense center) to select a policy based in-part on the user identity obtained by the identity manager or security context obtained by the defense center, and to prompt application of the selected policy. The policies are indicative of user / device authorization entitlements and restrictions to utilization of certain network resources, network services or applications. Dynamic policy selection and targeted responses can be used, for example, against a user who gains network access with stolen user ID and password, and subsequently attempts malicious behavior. In particular, the malicious behavior is detected and identified, and the malicious user can then be restricted from abusing network resources without adversely affecting other users, groups, network devices, and other network services.

An acoustically tuned earpiece is provided. Venting is performed by boring a control port, separate from the output port, into the driver. The diameter of the control port must be sufficiently small to restrict the flow of air into and out of the driver, thus isolating the acoustic performance of the driver from the volume and / or the sealing capabilities of the earpiece enclosure. The exact size of the venting port is selected to achieve the desired acoustic performance. In all cases, the control port has a cross-sectional area that is less than 25 percent of the cross-sectional area of the driver's output port. In order to optimize the size of the control port, an iterative process is preferably used in which the cross-sectional area of the control port is gradually increased while monitoring the performance of the driver compared to a target response.
