  • Patent number: 10318736
    Abstract: Various examples described herein provide for firmware verification on a peripheral device that can couple to a computing device. Before operating firmware is executed on the peripheral device, boot firmware can execute on the peripheral device and cause the peripheral device to generate a hash of the operating firmware. The peripheral device can transmit the hash to a validator external to the peripheral device, such as a management processor. The peripheral device can receive, from the validator, a validation decision based on the transmitted hash. In response to the validation decision indicating invalidity of the operating firmware, the peripheral device can execute recovery firmware to cause the peripheral device to retrieve replacement firmware. Depending on the example, the retrieved replacement firmware may replace the operating firmware or the operating firmware may be updated based on the retrieved replacement firmware.

  • Patent number: 10305874
    Abstract: A user may desire to execute a process in a target environment. However, administrators may want control over processes that haven't been preapproved to prevent the execution of processes that may affect security and compliance within the environment. Implementation of a multi-factor execution gateway may grant the user limited access to execute the process himself at an otherwise restricted, protected, or decoupled environment, while ensuring security and compliance by obtaining approval from the appropriate authorities. For example, a request to execute the process in the environment may be detected, and a fingerprint may be generated based on parameters of the request. A signature for the fingerprint in the form of private key(s) acquired from authorizer(s) based on a level of authorization required for the process may be received to generate a key, and execution of the process may then be allowed at the environment using the key.

  • Patent number: 10289425
    Abstract: The present application is directed to access isolation for multi-operating system devices. In general, a device may be configured using firmware to accommodate more than one operating system (OS) operating concurrently on the device or to transition from one OS to another. An access isolation module (AIM) in the firmware may determine a device equipment configuration and may partition the equipment for use by multiple operating systems. The AIM may disable OS-based equipment sensing and may allocate at least a portion of the equipment to each OS using customized tables. When transitioning between operating systems, the AIM may help to ensure that information from one OS is not accessible to others. For example, the AIM may detect when a foreground OS is to be replaced by a background OS, and may protect (e.g., lockout or encrypt) the files of the foreground OS prior to the background OS becoming active.

  • Patent number: 10216586
    Abstract: A primary system is established at a first site. The primary system hosts an application and a primary database for remote users that use the application to manage data of the primary database. A unified data layer is established at a remote site. The unified data layer provides access to data of the primary database without providing access to the primary database. A triggering event that impairs the ability of the primary system to host the application is detected. A recovery system is instantiated in response to detecting the triggering event. The recovery system includes both a recovery instance of the application and a recovery database for the data of the application. The recovery database is populated using the unified data layer. The recovery system is activated such that remote users can access the recovery instance of the application to manage data of the recovery database.

  • Patent number: 10185553
    Abstract: Variables utilized in device firmware that provides various boot and runtime services are repaved in a fault-tolerant manner within a secure store in a durable, non-volatile device memory during an FOTA update process. A spare region in the secure store is utilized to temporarily hold a back-up of a primary region in which the firmware variables are written. Using a transaction-based fault-tolerant write (FTW) process, the variables in the primary region can be repaved with variables contained in a firmware update payload that is delivered from a remote service. In the event of a fault in the variable region repaving process, either the primary or spare region will remain valid so that firmware in a known good state can be utilized to enable the device to boot successfully and the variable region repaving in the FOTA update process may be restarted.

  • Patent number: 10171425
    Abstract: Methods and systems are disclosed that provide active firewall control for network traffic sessions within virtual processing platforms. Client agent instances run within virtual machine (VM) platforms (e.g., hypervisor, container, etc.) within virtual processing environments and enforce access, proxy, and/or other firewall rules with respect to network traffic sessions for application instances also running within the VM platforms. For certain embodiments, the agent instances collect information about applications and services running within the VM platforms and use this collected information to automatically enforce firewall rules. Additional disclosed embodiments redirect packets from “bad” network sources to a proxied application instance that interacts with the “bad” network source. This proxied interaction allows an agent instance monitoring the proxied session to analyze and assess the actual activity by the “bad” network source without putting the original data or network service at risk.
