Abstract
Described is a baseboard management controller (BMC). The BMC comprises a BMC flash storage storing firmware and an access permission table. The access permission table defines an access control policy for access requests to peripherals communicatively coupled to the BMC. The BMC further comprises an access control chip comprising one or more processors and a write-once memory. The write-once memory stores a copy of the access permission table. The access control chip is configured to manage access to the peripherals using the access permission table.
