摘要： At least one anomaly associated with at least one actual hardware element in a computer system having a plurality of hardware elements is addressed. The anomaly is detected, and, responsive to the detection, a virtualization layer is inserted between (i) an operating system of the computer system, and (ii) the plurality of hardware elements. Hardware emulation and/or selective hardware activation/deactivation are performed on the at least one actual hardware element by the virtualization layer. The insertion of the virtualization layer is accomplished in an on-the-fly manner.

摘要： A virtualization layer is inserted between (i) an operating system of a computer system, and (ii) at least one of a memory module and a storage module of the computer system. At least one of read access and write access to at least one portion of the at least one of a memory module and a storage module is controlled, with the virtualization layer. The insertion of the virtualization layer is accomplished in an on-the-fly manner (that is, without rebooting the computer system) An additional aspect includes controlling installation of a security program from the virtualization layer.

摘要： A method for protecting the integrity of a set of memory pages to be accessed by an operating system of a data processing system, includes running the operating system in a virtual machine (VM) of the data processing system; verifying the integrity of the set of memory pages on loading of pages in the set to a memory of the data processing system for access by the operating system; in response to verification of the integrity, designating the set of memory pages as trusted pages and, in a page table to be used by the operating system during the access, marking non-trusted pages as paged; and in response to a subsequent page fault interrupt for a non-trusted page, remapping the set of pages to a region of the data processing system memory which is inaccessible to the virtual machine.

摘要： A firewall system adapted for location outside the client machine, preferably in the same data processing device as the client machine but outside a virtual machine containing the client machine. Control logic of the firewall system receives incoming and outgoing connections from the network and client machine respectively. In response to a connection request initiating a connection between respective endpoints in the network and client machine, the control logic performs a security assessment comprising obtaining from at least one of the network and client machine information indicative of the security state of the endpoint therein, and allows or inhibits the connection in dependence on the result of the security assessment. The security assessment may be performed in accordance with a security policy of the system, and different security assessments may be performed for different connection requests in accordance with the security policy.
