摘要： A computing platform 20 runs a compartmented operating system 22 and includes a trusted device 23 for forming an integrity metric which a user can interrogate to confirm integrity of the operating system. Also, the integrity of an individual compartment 24 is verified by examining status information for that compartment including, for example, the identity of any open network connections, the identity of any running processes, and the status of a section of file space allocated to that compartment 24. Hence, the integrity of an individual compartment 24 of the compartmented operating system 22 can be demonstrated.

摘要： A computing platform 20 provides multiple computing environments 24 each containing a guest operating system 25 provided by a virtual machine application 26. Optionally, each computing environment 24 is formed in a compartment 220 of a compartmented host operating system 22. A trusted device 213 verifies that the host operating system 22 and each guest operating system 25 operates in a secure and trusted manner by forming integrity metrics which can be interrogated by a user 10. Each computing environment is isolated and secure, and can be verified as trustworthy independent of any other computing environment.

摘要： A virtual network has network interfaces coupled by a multipoint tunnel (100) through a forwarding network (40), each interface having a forwarding address in an address space of the forwarding network, each network interface having a reconfigurable address mapper (320) for determining a forwarding address for a packet, and encapsulating the packet with its forwarding address so that the forwarding network can forward the data packet transparent to its destination address. This makes the virtual network more agile since changes to the virtual network can be achieved by reconfiguring the corresponding forwarding addresses without needing to set up new tunnels new routing to these different tunnels. The forwarding network need not be aware of the virtual network and so no adaptation of the forwarding network or specialised hardware is needed.
摘要翻译：虚拟网络具有通过转发网络（40）通过多点隧道（100）耦合的网络接口，每个接口在转发网络的地址空间中具有转发地址，每个网络接口具有可重配置地址映射器（320），用于确定分组的转发地址，并用转发地址封装分组，使转发网络能够将数据包转发到目的地址。这使得虚拟网络更加灵活，因为可以通过重新配置相应的转发地址来实现对虚拟网络的更改，而无需为新隧道建立新的路由到这些不同的隧道。转发网络不需要知道虚拟网络，因此不需要转发网络或专用硬件的适配。

摘要： A system has a virtual overlay infrastructure mapped onto physical resources for processing, storage and network communications, the virtual infrastructure having virtual entities for processing, storage and network communications. Virtual infrastructures of different users share physical resources but are isolated and have their own management entities. An interface between infrastructures allows controlled relaxation of the isolation, using a gateway between virtual nets, or shared virtual storage devices. This can allow businesses to share data or applications, while maintaining control of security.

摘要： Access to a data processor is controlled by determining if a requested function command conforms to a set of parameters, the set of parameters being derived from previously executed function commands. If the requested function command does not conform to the set of parameters the data processor is controlled to temporarily hold the execution of the requested function commands.

摘要： A process 23 runs directly on a host operating system 22, until the process 23 attempts an operation which can affect security of the host operating system 22 (such as loading a kernel module or using system privileges). A guest operating system 25 is then provided running as a virtual machine session within a compartment 24 of the host operating system 22 and running of the process 23 continues using the guest operating system. Operations of the process 23 which can affect security of the host operating system 22 are instead performed on the guest operating system 25, giving greater security. The guest operating system 25 is only invoked selectively, leading to greater overall efficiency.
摘要翻译：进程23直接在主机操作系统22上运行，直到进程23尝试可能影响主机操作系统22的安全性的操作（诸如加载内核模块或使用系统特权）。然后，客机操作系统25作为虚拟机会话被提供在主机操作系统22的隔间24内，并且进程23的运行继续使用客户机操作系统。替代地，在客户操作系统25上执行可能影响主机操作系统22的安全性的过程23的操作，从而提供更大的安全性。客户操作系统25仅被选择性地调用，导致更高的整体效率。
