Abstract:
The present disclosure is directed to secure sensor data transport and processing. End-to-end security may prevent attackers from altering data during the sensor-based security procedure. For example, following sensor data capture execution in a device may be temporarily suspended. During the suspension of execution, sensor interface circuitry in the device may copy the sensor data from a memory location associated with the sensor to a trusted execution environment (TEE) within the device. The TEE may provide a secure location in which the sensor data may be processed and a determination may be made as to whether to grant access to the secure resources. The TEE may comprise, for example, match circuitry to compare the sensor data to previously captured sensor data for users that are allowed to access the secured resources and output circuitry to grant access to the secured resources or to perform activities associated with a security exception.
Abstract:
A method, system and computer-readable storage medium with instructions to migrate full-disk encrypted virtual storage between blade servers. A key is obtained to perform an operation on a first blade server. The key is obtained from a virtual security hardware instance and provided to the first blade server via a secure out-of-band communication channel. The key is migrated from the first blade server to a second blade server. The key is used to perform hardware encryption of data stored on the first blade server. The data are migrated to the second blade server without decrypting the data at the first blade server, and the second blade server uses the key to access the data. Other embodiments are described and claimed.
Abstract:
Various embodiments are generally directed to techniques for supporting the distributed execution of a task routine among multiple secure controllers incorporated into multiple computing devices. An apparatus includes a first processor component and first secure controller of a first computing device, where the first secure controller includes: a selection component to select the first secure controller or a second secure controller of a second computing device to compile a task routine based on a comparison of required resources to compile the task routine and available resources of the first secure controller; and a compiling component to compile the task routine into a first version of compiled routine for execution within the first secure controller by the first processor component and a second version for execution within the second secure controller by a second processor component in response to selection of the first secure controller. Other embodiments are described and claimed.
Abstract:
Apparatuses, methods and storage medium associated with reverse DRM geo-fencing are disclosed. In embodiments, an UAV may comprise sensors to provide sensor data for aerial operation over or near a geographic area, and collect sensor data of a target within the geographic area, and a reverse DRM geo-fence policy enforcement manager to enforce reverse DRM geo-fence policies on operation of the sensors while the UAV operates over/near the geographic area. In other embodiments, a base station may include a reverse DRM geo-fence policy generator to instruct an UAV to enforce reverse DRM geo-fence policies on operation of sensors of the UAV on collecting sensor data of the target within the geographic area while the UAV operates over or near the geographic area. Other embodiments may be disclosed or claimed.
Abstract:
Various embodiments are generally directed to an apparatus, method and other techniques for allocating a portion of the memory as system management random access memory (SMRAM) including a system management interrupt (SMI) handler for a system management mode (SMM), the SMI handler to handle SMIs for the SMM, generating a page table for the SMM, the page table comprising one or more mapped pages to map virtual addresses to physical addresses for the SMM, and setting one or more page table attributes for the page table to prevent a malicious code attack on the SMM.

Abstract:
Various embodiments are directed to creating multiple device blocks associated with hardware devices, arranging the device blocks in an order indicative of positions of the hardware devices in a hierarchy of buses and bridges, and enabling access to the multiple device blocks from an operating system. An apparatus comprises a processor circuit and storage storing instructions operative on the processor circuit to create a device table comprising multiple device blocks, each device block corresponding to one of multiple hardware devices accessible to the processor circuit, the device blocks arranged in an order indicative of relative positions of the hardware devices in a hierarchy of buses and at least one bridge device; enable access to the device table by an operating system; and execute a second sequence of instructions of the operating system operative on the processor circuit to access the device table. Other embodiments are described and claimed herein.
Abstract:
Techniques related to preventing unauthorized access to a computing device are disclosed. The techniques include a machine-readable medium, on which are stored instructions, comprising instructions that when executed cause a device to identify a host hardware configuration, obtain a policy based on the host hardware configuration, monitor two or more memory transactions based on the policy, identify, based on the memory transactions, a memory transaction pattern, wherein the memory transaction pattern is associated with an attempt to obtain unauthorized access to the device, and take one or more actions to interfere with attempts to obtain unauthorized access to the device based on the policy.
Abstract:
Techniques and computing devices for persistent firmware transfer monitoring and, more specifically, but not exclusively, to a resource filter within a firmware resource monitor configured to persistently store resource information after a boot operation. In one embodiment, for example, an apparatus for persistent firmware transfer monitoring in a computer system comprises at least one memory, at least one processor, and a resource filter comprising logic, at least a portion of the logic comprised in hardware and executed by the processor. The logic to may be configured to receive a list of required resources during a boot operation and receive a list of excluded resources. The resource filter may be further configured to persistently store the list of required resources and the list of excluded resources after the boot operation has completed. It may be determined that one or more changes occurred to either of the list of required resources and the list of excluded resources during the boot process, and a security alert may be generated indicating a potential security threat. Other embodiments are described and claimed.
