Publication number: 20230128572Abstract: Systems and methods are provided for customer validation of hardware of an IHS (Information Handling System). During factory provisioning of the IHS, a signed inventory certificate is uploaded to the IHS that identifies factory installed components of the IHS. Upon deployment of the IHS, a customer issues a request for hardware validation, such as via an API exposed by a trusted component of the IHS. The IHS generates a certificate signing request (CSR) that specifies factory-installed hardware components of the IHS. The CSR is transmitted to the customer for use in generating an inventory certificate signed by a certificate authority that is selected by the customer. The customer's signed inventory certificate is stored to the IHS and used in validating some or all of the hardware of the IHS by comparing detected hardware components of the IHS against the inventory specified in the inventory certificate received from the customer.Type: ApplicationFiled: October 22, 2021Publication date: April 27, 2023Applicant: Dell Products, L.P.Inventors: Mukund P.
