Abstract
Some examples described relate to securing a memory device of a computing system. For instance, a method may comprise comparing a command for the memory device to each command in a list of commands. The command is accepted when the command matches an authorized command in the list of commands. The accepted command is issued to the memory device.
Claims15
A method for securing a memory device of a computing system, comprising:
- comparing a command for the memory device to each command in a list of commands;
- accepting the command when the command matches an authorized command in the list of commands;
- and
- issuing the accepted command to the memory device.
A system for securing a memory device in a computing system, comprising:
- a flash controller coupled to the memory device;
- and
- registers coupled to the flash controller, wherein:
- a list of commands are located in the registers;
- a command comparator compares a command stored in a command register to each command in the list of commands to determine if the command is authorized;
- and
- a command acceptor identifies the command as authorized to the flash controller.
A non-transitory, computer-readable medium comprising instructions that, when executed by a processor, instruct the processor to:
- compare a command stored in a command register to a list of authorized commands stored in registers in a baseboard management controller;
- accept the command if the command and an associated parameter match an authorized command and its associated authorized parameter in the list of authorized commands;
- and
- issue the accepted command to a memory device.
