Abstract: A method of assessing a network uses a model (450) having nodes (100, 110) to represent parts of the network infrastructure and the application services, and having links to represent how the nodes influence each other. Dependencies or effects of the application services are found by determining paths through the nodes and links of the model (530). Such assessment can be useful for design, test, operations, and diagnosis, and for assessment of which parts of the infrastructure are critical to given services, or which services are dependent on, or could have an effect on a given part of the infrastructure. The dependencies or effects can encompass reachability information. The use of a model having links and nodes can enable more efficient processing, to enable larger or richer models. What changes in the dependencies or effects result from a given change in the network can be determined (830).

Abstract: A method of monitoring compliance with a business process comprising the steps of: generating, from a record of the business process and further information not expressed explicitly within the record of the process, a canonical model of all processes of a given genre which are to be monitored; applying the canonical model to the process as recorded to generate a process-specific model in which specific process operations are expressed in canonical form; and measuring the performance of the process by generating reports, based on the algorithms contained within the process-specific model and data generated by actual performance of the process, thereby to indicate whether the process is compliant.

Abstract: A detection seat for an IC detection device includes a frame and an integrated circuit coupling seat. The frame is mounted on a detection board of an integrated circuit detection device. The IC coupling seat includes an outer perimeter releasably engaged with the frame. The IC coupling seat includes a recessed portion adapted for receiving an integrated circuit to be tested. The recessed portion includes a plurality of contact terminals arranged corresponding to a plurality of pins of the integrated circuit to be tested. When the detection board is changed, the frame or the IC coupling seat can be replaced with a desired one without the need of replacing the whole IC detection seat.

Abstract: A method of auditing a communications session by using a secure device comprises: operating a communications protocol in said secure device; and producing an audit record of at least one transaction carried out by said secure device.

Abstract: A method for packaging digital evidence for long term validation comprises forming a package of a digital document (10), an electronic signature (12) for the document (10), together with evidence (16) of the authority of the signature in the document and a time stamp (20) indicating when the document was digitally signed. All of the pieces form parts of the packaged evidence.

Abstract: A software system for installation on computing apparatus (and a method of installing such a software system on computing apparatus), wherein the software system is provided in the form of a software package including a plurality of software components, one or more of the software components being provided as a plurality of different implementations, the apparatus including an installation engine for installing the software system only a selected one implementation of the or each of the software components having multiple implementations, and a random selector module for selecting one of the plurality of implementations of a software component for installation.

Abstract: A method of applying policy enforcement in a computing system comprises applying an authorisation policy within a secure hardware domain; and applying a digital signature within a secure hardware domain.

Abstract: A method of producing an audit record of at least one event, comprises: creating a message comprising: data relating to said event; a digest data; a time data; and signing said event data, digest data, and time data.

Abstract: An operating system for processing multiple tasks, the operating system comprising means for generating the multiple tasks including data indicating a time at which or by which (and/or a frequency at which and/or one or more events in response to which) the task should be processed, means for associating time stamp data with the tasks, said time stamp data being indicative of the date and/or time at which the respective tasks were generated, and means for receiving said tasks for processing at a particular time, determining from the associated time stamp for each task the date and/or time at which said task was generated, determining whether or not the processing of said task at said particular time is consistent with one or more predetermined operating system policies, and causing said task to be processed at said particular time only if such processing is determined to be consistent with said operating system policies.

Abstract: A long-term digital document storage system, comprising means for receiving one or more digital documents for storage in a storage means, one or more storage sites for storing, in association with the one or more digital documents, metadata defining a data management strategy or “agreement” with respect to the one or more digital documents, the “agreement including one or more “clauses” defining respective constraints to be applied by the storage system to the one or more digital documents, the system further comprising means for configuring the data management strategy or agreement by defining or specifying at least some of the constraints individually according to specific requirements related to said one or more pieces of digital data. As such, the invention is concerned with the fine-grained management of documents within a storage system by the flexible definition and association with a document of a number of clauses (i.e.
