Abstract: In an example, there is provided a method for attesting to a management state of a device platform configuration, based on a signed data structure that represents a device management status and a time-based value from a secure cryptoprocessor of the device. The signed data structure is sent to a management system for validation based on a comparison to the state of the cryptoprocessor at the time of signing the data structure.

Abstract: In an example, a machine-readable medium includes instructions that, when executed by a processor, cause the processor to order, as part of an execution of a trusted process, a plurality of processes into a sequence comprising a first process, at least one intermediate process, and a last process. The machine-readable medium may further comprise instruction to cause the processor to generate, as part of an execution of the first process, a value based on a code portion of the process following the first process in the sequence, and to generate, as part of an execution of each intermediate process, a respective value based on the value generated by the process preceding the intermediate process in the sequence and based on a code portion associated with the process following the intermediate process in the sequence.

Abstract: There is disclosed a method, computer program product and a system for regulating execution of a suspicious process, comprising determining a file system location of an executable file associated with the suspicious process, encrypting the file, and creating a wrapper for the file with the same file name and location as the file associated with the suspicious process.

Abstract: Examples associated with process verification are described. One example includes a process operating in a general operating environment of the system. From an isolated environment, a protection module modifies the behavior of the process by modifying data associated with the process while the process is in operation. The protection module verifies whether the behavior of the process has changed in accordance with the modification. The protection module takes a remedial action upon determining the process has been compromised.

Abstract: In an example there is provided a method of applying a mitigation action to a computing system. The method comprises receiving notification of an intrusion event on a computing system. The notification identifies one or more of data, and a process affected by the intrusion event. The method comprises accessing state data corresponding to a state of the computing system prior to the intrusion event, accessing a policy specifying one or more mitigation actions to be applied to the one or more of data, and a process in response to an intrusion event, restoring the one or more of data, and the process on the basis of the state data, and applying a mitigation action according to the policy.

Abstract: Examples associated with digital composition hashing are described. One example method includes receiving a digital composition file from a user. The digital composition file may include a top-level design and a hierarchy of sub-level designs. A hashed structure may be generated from the digital composition file, where a node in the hashed structure for the first sub-level design is generated based on hashes of sub-level designs below the first sub-level design in the hierarchy. The hashed structure and a hash of the digital composition file are stored in association with the user.

Abstract: An apparatus includes a first processing resource to execute a program code, and a second processing resource separate from the first processing resource. The program code includes an embedded execution unit. The execution unit, during execution of the program code, calculates a first security value for a part of the program code. The second processing resource runs a validation program. The validation program receives the first security value, checks the first security value against a second security value calculated from a corresponding part of a reference copy of the program code to obtain a check result, returns the check result to the execution unit. The execution unit performs a security-related action in response to a check result indicating a mismatch between the first security value and the second security value.

Abstract: A device platform, in some examples, comprises a security processor that may create a private/public cryptographic key pair, and data representing evidence of creation of the key pair, provide access to the key pair and data from an operating system component of the device platform, where the public key part of the key pair may be used to verify management commands. The device platform may validate the key pair and data in a trusted execution state.

Abstract: A controller for a fulfilment service operation is described in which the controller, before initiating fulfilment of the job, operates to determine if an authorised user is present at a fulfilment service device and to determine if the user intends to remain attendant at the fulfilment service device for the duration of fulfilment of the job. If the user moves away from the fulfilment service device, the controller operates to pause the job. If the user remains away from the fulfilment service device for a period of time, the controller operates to cancel the job.
