Abstract: A technique includes an operating system agent of a computer system monitoring a process to detect whether an integrity of the process has been compromised. The monitoring includes the operating system agent scanning a data structure. The process executes in a user space, and the data structure is part of an operating system kernel space. The technique includes a hardware controller of the computer system listening for a heartbeat that is generated by the operating system agent. The hardware controller takes a corrective action in response to at least one of the hardware controller detecting an interruption of the heartbeat, or the operating system agent communicating to the hardware controller a security alert for the process.

Abstract: In some examples, a system receives first measurements of data items used by a build server in building an executable program, the data items copied from a data repository to a storage partition that is separate from the data repository, and the storage partition to store the data items relating to building the executable program by the build server. The system determines, based on the first measurements and according to a policy specified for the storage partition, whether a corruption of the data items used by the build server in building the executable program has occurred.

Abstract: Example implementations relate to a method and system for provisioning an identity certificate for a BMC of a platform. Based on the certificate signing request (CSR) received from the BMC, a certificate authority (CA) associated with the platform manufacturer may verify the identity of the security processor and private key of BMC. A cryptographic audit session log between a provisioning service of the platform and the security coprocessor of the platform is received along with the CSR at the CA implemented in a cloud system. The CA verifies the signature on the received cryptographic audit session log. After verification, validation tools at the cloud system determine a first time and second time associated with the security coprocessor. When the difference between the first time and the second time is below an expected time of cryptographic communication, the CSR is considered as a valid request and an identity certificate for the BMC is generated and transmitted to the platform.

Abstract: 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.

Abstract: 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. Each virtual infrastructure can be passivated by suspending applications, stopping operating systems, and storing state, to enable later reactivation. This is simpler for a complete virtual infrastructure than for groups of virtual entities and physical entities. It enables cloned virtual infrastructure to be created for testing, upgrading or sharing without risk to the parent. On failure, reversion to a previous working clone is feasible.

Abstract: 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. Each infrastructure has its own infrastructure controller to create and configure the infrastructure. It has a user accessible part (CFC) for configuration of that user's infrastructure, and a user inaccessible part (UFC) able to access the mapping and the physical resources. This increases user control to ease system administration, while maintaining security by limiting access to the mapping.

Abstract: A method of multi-domain authorization/authentication on a computer network comprises: a user making a request to a policy enforcement point of a computer for access to information on the computer; providing a location address for a user's authorization and/or authentication information, a policy decision point of the service on the computer network then verifying the authorization/authentication information; and the user being given access by the PEP to the information or the service requested, if the request is accepted, wherein the user's authorization/authentication and/or further information is located on a meta policy decision point (MPDP).

Abstract: A network gateway (1005) is described, wherein an object invocation (1020) containing an embedded object reference (1025), which points to a further object (1002), is modified on passing through the gateway. The gateway validates the object invocation and enacts a number of security tests thereon before forwarding it on. In preferred embodiments, the embedded object reference is replaced by an object reference (1035) to a gateway proxy specifically for the further object (1002). The replacement object reference (1035) also includes enough information that the original object reference (1025) can be recovered. The gateway proxy is generated on or after receipt of the invocation (1020). In the event the further object (1002), which was the subject of the object reference, is itself invoked, the invocation is directed to the gateway proxy, which in turn recovers the original object reference and forwards the invocation on to the further object (1002).
