Abstract
A storage device with hardened security features for safe execution of scripts has a storage medium, an interface, a set of safe commands, and a script interpreter. The interface is adapted to communicatively couple the storage device to a host system and to transport interface commands and information between the host system and the storage device. The set of safe commands is stored on the storage medium. The script interpreter is disposed within the storage device for processing scripts based on one or more received interface commands. The script interpreter is adapted to enforce a strict ordering of script execution and to terminate script execution and roll back any changes associated with the script execution if an interface command invokes a script in violation of the strict ordering.
