A system for shutting down a process of a database is provided. In some aspects, the system performs operations including tracking, during startup of a process, code locations of a process in the at least one memory. The operations may further include tracking, during runtime of the process and in response to the tracking the code locations, memory segments of the at least one memory allocated to the process. The operations may further include receiving an indication for a shutdown of a process. The operations may further include waking, in response to the indication, at least one processing thread of a plurality of processing threads allocated to a database system. The operations may further include allocating a list of memory mappings to the plurality of processing threads. The operations may further include freeing, by the first processing thread, the physical memory assigned to the processing thread by the memory mappings.

To facilitate improved email and device security, embodiments of systems and methods include intercepting, by a processor associated with an entity, an internet request, where the internet request is produced by a link received in an email at a first computing device. The processor determines that the link is externally bound relative to an entity network. The processor determines an existence of a sandbox environment instance in a set of existing sandbox environment instances. The processor routes the link through the sandbox environment instance. The processor updates the sandbox log in the database based on the sandbox environment instance and the link. The processor causes to display on a screen of the first computing device a user interface for interacting with the link in the sandbox environment instance, and the processor logs activities associated with interacting with the link in a security log.

A power supply controller system includes a power supply portion, arithmetic processing portions, and first and second monitoring circuits configured to monitor an integrity of power supply of the power supply portion. The first monitoring circuit instructs a second arithmetic processing portion to stop an operation thereof when a first watchdog timer is not reset for a predetermined period of time. The second monitoring circuit instructs a first arithmetic processing portion to stop an operation thereof when a second watchdog timer is not reset for a predetermined period of time. The first monitoring circuit further includes a third watchdog timer periodically reset by any one of the first arithmetic processing portion and the second arithmetic processing portion and instructs another arithmetic processing portion to stop an operation thereof when the third watchdog timer is not reset for a predetermined period of time.

A process for generating an access credential by a communication device may include determining whether a communication device successfully executed a predetermined shutdown sequence when the communication device last transitioned to an inactive state, determining whether the communication device has synchronized with an authorization network subsequent to transitioning back to an active state, and generating the access credential including a timestamp. The access credential may indicate whether the access credential has reliable timestamp information. The access credential can be provided to an access device associated with an authorization network to authenticate the communication device.

In a stream computing application shutdown, a shutdown message is received by a source operator of the stream computing application. In response, the source operator stops acquiring data from external sources, sends any cached data to an output queue of the source operator, sends the shutdown message to the output queue of the source operator, and sends the cached data and shutdown message to an input queue of another operator in the stream computing application. The source operator then terminates. In response to receiving the shutdown message, the other operator completes the processing of data in its input queue and sends any outputs from the processing of the data in its input queue to one or more output destinations. The other operator then terminates. In this manner, a stream computing application may be shut down while ensuring that any already inputted data is processed to completion, thus avoiding data loss.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a management device. The apparatus may be a management device. The management device receives a first command. The management device determines whether the management device is in a protected mode for executing a protected process. The management device, in response to a determination that the management device is in the protected mode, determines whether the first command, when executed, interrupts the execution of the protected process. The management device, in response to a determination that the first command interrupts the execution of the protected process, discards the first command.

A device-local key derivation scheme generates, during a first boot session for an electronic device, a sealing key that is derived at least in part from a device-generated random seed and an internal secret that is unique to the electronic device. After generating the sealing key, access to the internal secret is disabled for a remainder of the first boot session and until a second boot session is initiated. At runtime, the sealing key is used to sign a module manifest that describes the software that is authorized to access the sealing key, and the module manifest containing the sealing key is persisted in non-volatile memory of the electronic device. The module manifest can be used to validate software during a subsequent boot session and to authorize software updates on the electronic device without relying on an external entity or external information to protect on-device secrets.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for extending application access across devices. In some implementations, an electronic device receives a request to provide access to the electronic device to a particular user that is not registered as a user of the electronic device. The electronic device receives authentication credentials for the particular user. The electronic device provides the authentication credentials to a server system and receives data from the server system that (i) indicates that the providing access to the electronic device in a guest mode is authorized, and (ii) indicates a state of an instance of an application installed on a second device. The electronic device provides access to the electronic device in the guest mode that provides an interface that at least partially recreates the state of the instance of the application installed on the second device.

One embodiment provides a system that facilitates a secure encryption proxy in a content centric network. During operation, the system receives, by an intermediate router from a content-consuming computing device, a first interest that includes a first name, signaling information encrypted based on a signaling key, and an inner interest encrypted based on an encryption key. The inner interest includes a name for a manifest that represents a collection of data. The intermediate router does not possess the encryption key. The system generates one or more interests for the data represented by the manifest. The system transmits to the content-consuming computing device a content object received in response to a generated interest, wherein the intermediate router transmits the responsive content object without receiving a corresponding interest from the content-consuming computing device, thereby facilitating reduced network between the content-consuming computing device and the intermediate router.

In described examples, an integrated circuit (IC) includes a first temperature sensor, a processor, a second temperature sensor, and a reset module. The first sensor senses a first body temperature of the IC. The processor asserts a thermal shutdown signal if the first body temperature exceeds a first threshold. In response to the thermal shutdown signal, the second sensor asserts a reset request signal and senses a second body temperature of the IC. If the second body temperature is less than a second threshold, the second sensor asserts a reset end signal. The reset module outputs a system reset signal to the first sensor and the processor if the reset request signal is asserted, and outputs a system recovery signal if the reset end signal is asserted. The first sensor and the processor deactivate if the system reset signal is asserted, and activate if the system recovery signal is asserted.
