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.
