  • Patent number: 12147589
    Abstract: In general, embodiments of the invention relate to a method and system for managing a storage system. In many traditional implementations host bus adapter (HBA) manages the storage device, however frequently the HBA cannot implement the necessary methods to secure a self-encrypting drive (SED). One or more embodiments of the invention use a baseboard management controller (BMC) to manage the security of the SEDs as well as the security life cycle of the SEDs, while the HBA acts as a passthrough conduit between the SED and BMC.

  • Publication number: 20240340319
    Abstract: A node for a VSAN includes a BMC, a processor, and a plurality of VSAN objects. The processor instantiates a Cluster Membership, Monitoring, and Directory Service (CMMDS) and a BMC Service Module (SM). The CMMDS implements a Security Policy and Data Model (SPDM) architecture. The CMMDS determines an inventory list of the VSAN objects and a SPDM authentication state for each of the objects, and provides the inventory list and the SPDM authentication states to the BMC SM. The BMC SM provides the inventory list and the SPDM authentication state to the BMC. The BMC determines that a first VSAN object is not authenticated based upon the SPDM authentication state of the first VSAN object, and directs the CMMDS to halt input/output (I/O) operations on the VSAN to the first VSAN object.

  • Publication number: 20240313983
    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.

  • Publication number: 20240169073
    Abstract: A storage enclosure of an information handling system includes multiple storage drives, and an expander device. The storage drives include one or more self-encrypting drives (SEDs). The expander device determines whether a SED enables a power disable capability. In response to detection that the SED enables the power disable capability, the expander device monitors a link status between the information handling system and the storage enclosure. In response to a link status change being detected, the expander device waits a period of time and determines the link status after the period of time. If the link status is link down, the expander device implements a power cycle in the storage drives. After the power cycle of the storage drives, the expander device sets the drives to a locked state.

  • Patent number: 11985258
    Abstract: Systems and methods provide validation of hardware components of an IHS (Information Handling System). An attestation certificate stored to the IHS specifies authenticated instructions for operation of a hardware component of the IHS. This attestation certificate is endorsed by a self-signed root attestation certificate. An identity certificate, also stored to the IHS, specifies an identity of the hardware component and is endorsed using an embedded keypair of the hardware component. The root attestation certificate is validated to ensure it corresponds to the hardware component specified in the identity certificate, where this validation confirms that a public key included in the identity certificate is identical to a public key included in the attestation certificate.

  • Patent number: 11954207
    Abstract: A system and method are disclosed for delegating, by a resource-constrained device, a privilege to a basic input/output system, wherein the privilege allows the basic input/output system to authenticate an endpoint device on behalf of the resource-constrained device. The system and method also includes generating an asymmetric security key that includes a private key and a public key and transmitting the public key to the basic input/output system, wherein the public key is included in a proxy certificate generated by the basic input/output system. In addition, the system and method includes establishing a secure session between the basic input/output system and the endpoint device using the private key and the proxy certificate, wherein the secure session is used by the basic input/output system to authenticate and verify that the endpoint device is authorized to perform an operation.

  • Patent number: 11755786
    Abstract: An Information Handling System (IHS) includes at least one hardware device in communication with a Baseboard Management Controller (BMC). The hardware device includes executable instructions for establishing a secure communication channel with the BMC, and subsequently receiving a list of allowed commands from the BMC. When a command is received by the hardware device, it determines whether the command is included in the list such that when the command is in the list and the command is received within the secure communication channel, the hardware device performs the command. However, when the command is in the list and the command is received outside of the secure communication channel, the hardware device ignores the command.
