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.

Abstract: In some examples, a security processor detects a potential attack in a system. In response to detecting the potential attack in the system, the security processor issues a command block indication to block processing of commands to access a nonvolatile memory. The security processor determines, based on monitored information, a likelihood of the potential attack being a real attack, and in response to the determined likelihood, triggers an erase of the nonvolatile memory.

Abstract: In some examples, a management controller is to dynamically vary a parameter that controls an operational characteristic of a bus when transferring different portions of information from a memory over the bus during a process of an electronic device in which a cryptographic operation is performed. The different portions of the information from the memory are to be transferred over the bus with different operational characteristics of the bus.

Abstract: An arrangement for securing a memory device of a computing system in which a memory access command is compared to each command in a list of commands. The command, with specified attributes, is authenticated when the command and its attributes match an entry in the list of commands. Following authentication, the command is evaluated according to usage and behavior metrics in order to identify and prevent unauthorized or malicious access of the memory device. If no violation of usage or behavior metrics is detected, the command may be issued to the memory device for execution.
