Abstract: A software Redundant Array of Independent Disk (RAID)/management trusted storage-device-based communication system includes a chassis housing a software Redundant Array of Independent Disk (RAID) subsystem, a storage device that is coupled to the software RAID subsystem and that includes a storage device memory subsystem, and a management subsystem that is coupled to the storage device. The management subsystem authenticates the storage device to establish management subsystem/storage device trust between the management subsystem and the storage device and, in response, uses the storage device to establish management subsystem/software RAID subsystem trust between the management subsystem and the software RAID subsystem. In response to establishing the management subsystem/storage device trust and the management subsystem/software RAID subsystem trust, the management subsystem transmits communications with the software RAID subsystem via the storage device memory subsystem in the storage device.

Abstract: A resilient software Redundant Array of Independent Disk (RAID)/management communication system includes a chassis housing a software RAID subsystem coupled to a plurality of storage devices that are also coupled to a management subsystem. The software RAID subsystem designates a first storage device in the plurality of storage devices as a primary storage device and a second storage device in the plurality of storage devices as a secondary storage device, and uses the respective storage device memory subsystem in the first storage device to transmit first management communications with the management subsystem. If the software RAID subsystem determines that the first storage device is unavailable, it uses the respective storage device memory subsystem in the second storage device to transmit second management communications with the management subsystem.

Abstract: Systems and methods provide for SPDM-enabled devices that conform to an SPDM specification. An SPDM-enabled device receives a request to provision a certificate chain on the device and sends an event notification message to a baseboard management controller. The event notification message indicates receipt of a request to provision a certificate chain in a slot on the SPDM-enabled device. The baseboard management controller evaluates the certificate chain against the device manufacturer's certificate profile policy. If the certificate chain is valid, then a validation successful message is sent to the SPDM-enabled device, which in turn sends a certificate provision response to a requesting device. If the certificate chain is not valid, then a validation failure message is sent to the SPDM-enabled device, which causes the SPDM-enabled device to enter a quarantine state.

Abstract: According to embodiments of the present disclosure, an Information Handling System (IHS), systems and methods for dynamic policy assignment of secure communication using Security Protocol and Data Model (SPDM) are disclosed. An Information Handling System (IHS) includes a first SPDM-enabled device conforming to a SPDM specification, receives a request to transmit data to a second SPDM-enabled device, obtain one or more policies associated with a corresponding one or more transmission criteria of the first SPDM-enabled device relative to the second SPDM-enabled device, and determine whether the data is to be encrypted based upon whether a transmission of the data meets the transmission criteria. Based upon the determination, encrypt the data prior to transmitting the data to the second SPDM-enabled device.

Abstract: A system for data processing, comprising a management controller operating on a processor and configured to load and execute one or more algorithms that provide the function of transmitting a request to a managed device using a Security Protocol and Data Model (SPDM) protocol and to receive a response from the managed device. A system management bus and security policy system operating on the processor is configured to execute one or more algorithms to process the response from the managed device to apply an SPDM security policy to the response.

Abstract: In one embodiment, an Information Handling System (IHS) includes multiple Security Protocol and Data Model (SPDM)-enabled devices in communication with multiple Baseboard Management Controllers (BMCs). Each of the BMCs includes executable code to negotiate with the other BMCs, management of a subset of the SPDM-enabled devices based on a hardware capability or a software capability of the SPDM-enabled device relative to the hardware capability or the software capability of the BMC, and manage the subset of devices by the BMC.

Abstract: Systems and methods provide multi-modal based updates to firmware utilized by a hardware component of an IHS (Information Handling System), where the firmware updates are managed by a remote access controller of the IHS that provides remote management of the hardware component. The remote access controller receives a notification of an update to an agreement for utilization of the hardware component, where the agreement indicates firmware modes authorized for use by the hardware component. Firmware modes are identified that are locally stored by the hardware component. Any firmware modes are identified that are authorized for use by the hardware component based on the updated first agreement and that are not locally stored by the hardware component, and the identified firmware modes are retrieved for local storage by the hardware component. In this manner, firmware utilized in an IHS remains consistent with applicable service agreements.

Abstract: A computing device component monitoring system includes at least one certificate generation system, and a computing device that includes a first component and that is coupled to the at least one certificate generation system via a network. The computing device receives a first component verification certificate from the at least one certificate generation system that identifies a first component lifetime after which the first component in the computing device should be replaced, and stores the first component verification certificate in a database that is accessible to the computing device. The computing device determines that the first component lifetime has been exceeded, and identifies a first component alert policy in response. The computing device generates a first component alert based on the first component alert policy.

Abstract: An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with multiple hardware devices of the IHS. The BMC includes executable instructions for transmitting a broadcast message to the hardware devices in which the broadcast message has a block of data including a digital signature of the BMC. Each of the hardware devices that receive the broadcast message are configured to transmit a broadcast acknowledgment message to the BMC. Using the block of data, the BMC and hardware devices may perform a mutual consensus procedure with other using a cryptographic hash function of the block of data.
