Abstract: An example method facilitates enabling Key Encryption Key (KEK) rotation for a running multi-tenant system without requiring system downtime or interruption. The example method facilitates decrypting a set of one or more DEKs using a preexisting KEK; using a new KEK to re-encode the DEKs using the new KEK, all while simultaneously enabling servicing of tenant requests. This is enabled in part, by strategic caching of tenant DEKs in a secure local memory, wherein the cached tenant DEKs are maintained in the clear and are readily accessible to running processes that are using the DEKs to decrypt and access tenant data, irrespective of the state of a background process used to implement the KEK rotation to the new KEK.

Abstract: An aspect of the present disclosure facilitates validation of responses received from server systems. In one embodiment, data values are maintained in a data source. Upon sending a request containing a query criteria to a server system, the server system retrieves data values satisfying the query criteria from the data source. A (actual) response is received from the server system, the actual response containing data values retrieved by the server system. Data values satisfying the query criteria are also retrieved directly from the data source and an expected response is constructed by incorporating the directly retrieved data values. The data values contained in the expected and the actual responses are then compared to determine a difference between the expected and actual responses as a basis for validating the actual response received from the server system for the request.

Abstract: The present disclosure generally relates to data storage devices, such as solid state drives (SSDs). A read threshold calibration operation is utilized to generate a calibrated read threshold for one or more voltage states of a cell of a MLC memory. A single-level cell (SLC) read is then executed to sense the ratio of bit values at the read thresholds of the voltage states, where SLC read refers to reading at a single read threshold, rather than to the cell type. The sensing results in a binary page with certain statistics of 1's and 0's. The ratio of 1's (or 0's) in the binary page is used to determine a deviation from the expected ratio, where the deviation is used to adjust the calibrated read threshold to match the voltage states of the MLC memory.

Abstract: One example includes a device that is comprised of a pre-power amplifier, a power amplifier, a signal path, and a dynamic bias circuit. The pre-power amplifier amplifies an input signal and outputs a first amplified signal. The power amplifier receives the first amplified signal and amplifies the first amplified signal based on a dynamic bias signal to produce a second amplified signal at an output thereof. The signal path is coupled between an output of the pre-power amplifier and an input of the power amplifier. The dynamic bias circuit monitors the first amplified signal, generates the dynamic bias signal, and outputs the dynamic bias into the signal path.

Abstract: Systems and methods are provided herein to dynamically update content restrictions for multiple users by detecting a first user in the proximity of a media device playing a first content item and detecting a second user entering the proximity of the media device. In response to detecting a second user entering the proximity of the media device and receiving a command from the first user that controls playing the first content, the system modifies a stored relationship between the first user and the second user to track the relationship between the first user and the second user. Thereafter, when the system detects the first user and the second user in the proximity of a media device playing a second content, in response, the system automatically performs an action that controls the playing of the second content (e.g., without user having to issue those commands).

Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.
