摘要:
A mapping system is provided that makes use of security data collected from various data sources. Following appropriate pre-processing, the mapping system analyses the security data to provide estimated values for parameters in a security model, the security model in turn being based on one or more mathematical representations.

The present invention provides a digital certificate (2, 32) comprising a plurality of credential attribute properties (6, 36), and a trust function (8, 42) embedded within the certificate as an executable file, which trust function can determine as a function of data (12, 44) available to it a trust value (14, 46) attributable to at least a part of the certificate at least partly by execution of the executable file. A corresponding method of communication is also disclosed.
摘要:
A method of communication is such that a first party (30) communicates a composite credential (54) across a distributed electronic network (44) to a second Party (32). The composite credential (54) includes a plurality of credentials (46-52).
摘要:
A customized security model template is created that is customized for a specific organization's security related procedures. The customized security model template is instantiated with parameters associated with the organization to create an instantiated security model, and a report is produced based on simulations of the instantiated security model that specifies metrics of the organization's security implementation.
摘要:
Compliance of a project is assessed by generating a graph including nodes representing attributes of the project, and populating a subset of nodes in the graph with attribute values of the project. A rule applicable to the subset of nodes is identified and applied to determine whether the attribute values comply with the rule.
摘要:
The present invention provides a digital certificate (2, 32), the certificate comprising a credential attribute function (6, 38) associated with a credential attribute property (5, 36), which credential attribute function is embedded in the certificate as an executable file, in which the credential attribute function can determine the value (12, 44) of the credential attribute property at least partly by execution of the executable file. A corresponding method is also disclosed.

A chemical vapor deposition method for forming an aluminum-silicon nitride layer upon a substrate uses an aluminum precursor, a silicon precursor and a nitrogen precursor under chemical vapor deposition conditions to deposit the aluminum-silicon nitride layer upon the substrate. The aluminum-silicon nitride layer has an index of refraction interposed between silicon nitride and aluminum nitride. The aluminum-silicon nitride layer also has a bandgap from about 4.5 to about 6 eV and a permittivity from about 6×10^-11 to about 8×10^-11 F/m. The aluminum-silicon nitride layer may be further thermally annealed to reduce a hydrogen content of the aluminum-silicon nitride layer.
摘要:
A method includes executing a hypervisor (165) with computing hardware (105) to implement a virtual machine (175); responsive to detecting a removable storage medium (115) communicatively coupled to the computing hardware (105), executing a virtualized migration control appliance (180) through the hypervisor (165) separate from the virtual machine (175); and blocking the virtual machine (175) from accessing data (185) stored by the removable storage medium (115) with the virtualized migration control appliance (180) if at least one governing policy prohibits the virtual machine (175) from accessing the data (185).
摘要:
The present invention relates generally to process control systems and devices and, more particularly, to an apparatus for and a method of implementing redundant controller synchronization for bump-less failover during normal and mismatch conditions at the redundant controllers. The redundant controllers are configured to transmit state information of the process control areas of the primary controller to the backup controller that is necessary for synchronizing the redundant controllers but is not typically transmitted to other devices during the performance of process control functions. Synchronization messages are transmitted from the primary controller to the backup controller each time one of the control areas executes to perform process control functions. In other aspects, the redundant controllers are configured to determine state information at the backup controller from other process control network information during a failover of the primary controller where a mismatch condition exists between the control areas of the two controllers during the downloading of reconfigurations, and to initialize the backup controller at startup when the mismatch condition exists.
