Abstract:
A system and method for managing the recovery key of a computer system is disclosed. The computer system includes a security layer, and the recovery key is stored locally to a memory location on the computer system, including, as examples, flash memory on the motherboard of the computer system or a USB port on the computer system. In operation, when it becomes necessary for the computer system to authenticate the recovery key, the recovery key may be retrieved from the local memory. The retrieval and storage of the recovery key may be managed by a remote administrator. The recovery key may be stored in a hidden partition in the storage location, and the recovery key may be cryptographically wrapped to add an additional layer of security.
Abstract:
During execution of BIOS at an information handling system, a processor communicates with the storage controller via a command line protocol (CLP) communications channel. Via the channel, the processor obtains identification information for storage devices associated with the storage controller. The processor communicates the identification information to a key management client, which obtains encryption keys based on the identification information from a key management server. The processor receives the encryption keys, and communicates them to the storage controller via the CLP communications channel. The CLP communications channel thus provides a convenient and flexible interface for communication of security information prior to execution of an operating system.
Abstract:
A credential caching system includes receiving a set of authentication credentials, storing the set of authentication credentials in a credential cache memory, wherein the credential cache memory is coupled with a management controller, and supplying the set of authentication credentials for automatic authentication during a reset or reboot. In the event of a security breach, the credential caching system clears the set of authentication credentials from the credential cache memory so that the set of authentication credentials may no longer be used for a reset or reboot.
Abstract:
A system and method for accessing and identifying the security parameters of a device in an information handling system is disclosed. A device in a computer system may operate according to a defined security protocol, and multiple security protocols may exist across the devices of the system. In operation, a configuration capability is defined within the PCI Express communications protocol. This capability includes a capabilities data structure through which parameters concerning the security parameters of the device may be identified and passed to a processor.

Abstract:
In accordance with the present disclosure, a system and method for performing a system memory save in tiered or cached storage during transition to a decreased power state is disclosed. As disclosed herein, the system incorporating aspects of the present invention may include a flash or other nonvolatile memory such as a solid-state drive, volatile memory, and at least one alternate storage media. Upon transition to a decreased power state, at least some of the data in the solid-state drive, for example, may be transferred to the at least one alternate storage media. After the SSD data is transferred, data stored in volatile system memory, such as a system context, may be transferred to the SSD memory. With the system context saved in SSD memory, power to the volatile system memory may be turned off.
Abstract:
In accordance with the present disclosure, a system and method for creating and dynamically maintaining power inventories of an information handling system is presented. A system for creating and dynamically maintaining power inventories of an information handling system may include a memory and a processor. The processor may be operable to generate power inventories for the information handling system and save the power inventories in the memory. Each of the power inventories may correspond to one of the power states of the information handling system. The processor may also be operable to dynamically update each of the saved power inventories in response to changes in the information handling system.
