    摘要: Method and Apparatuses for determining integrity of a platform and notifying a remote system. In one embodiment a verification agent accesses a portion of a memory on the platform at initialization of the platform to determine if the data has been compromised or corrupted. The verification agent causes the information to be transmitted to a remote system. The verification agent may be local to the platform for which integrity is determined, and transmit the information to a remote administrator. Alternatively, the agent may access the platform over a bus or private channel, or a network connection and indicate information regarding the verification process to an entity remote to the tested platform.

    摘要: A system and method to support platform firmware as a trusted process. Measurement of a trusted portion of original firmware are measured by a core root of trust measurement (CRTM). The measurement is stored in a secure manner during pre-boot. During operating system (OS)-runtime, requests are made to access an unqualified current version of firmware corresponding to a secure execution mode. A portion of the current firmware analogous to the trusted portion is measured. The measurements of the trusted original portion and unqualified current portion are compared to verify they match. If they match, it indicates that the current portion and the trusted portion are one in the same. Thus, the current portion of firmware is trustworthy. Accordingly, the firmware may be executed as a trusted process. Embodiments employ locality to enforce the trusted process. The use of locality prevents unqualified users (i.e., software) from accessing data stored by trusted firmware.

    摘要: A method for authenticating clients and boot server hosts to provide a secure network boot environment. Messages are exchanged between a client and a boot server or authentication server proxy for the boot server during pre-boot operations of the client to authentic the boot server and the client. In one embodiment, authentication is performed by comparing shared secrets stored on each of the client and the boot server or authentication proxy. The shared secret comprises authentication credentials that may be provisioned by an administrator, user, or by the client itself via a trusted platform module. Authentication provisioning schemes include an Extensible Authentication Protocol (EAP) exchange. In one embodiment, authentication is performed during the pre-boot via an authenticated Dynamic Host Configuration Protocol (DHCP) process. The scheme provides a faster and more simplified authentication mechanism, without requiring extensive set-up for IT administrators or significantly changing the login and OS boot user experience.

    摘要: A method and system using a virtual lock for boot block flash are disclosed in which code from a boot block of a flash memory is executed. The boot block is hardware protected. One or more ancillary boot blocks in the flash memory are locked based on the executed code such that the ancillary boot blocks are virtually hardware locked. The ancillary boot blocks can be virtually hardware locked using a programmable technique.

    摘要: Technologies for media protection policy enforcement include a computing device having multiple operating systems and a data storage device partitioned into a number of regions. During execution of each of the operating systems, a policy enforcement module may intercept media access requests and determine whether to allow the media access requests based on platform media access policies. The media access policies may allow requests based on the identity of the executing operating system, the region of the data storage device, or the requested storage operation. Prior to loading a selected operating system, a firmware policy enforcement module may determine a region of the disk storage device to protect from the selected operating system. The firmware policy enforcement module may configure the data storage device to prevent access to that region. The media access policies may be stored in one or more firmware variables. Other embodiments are described and claimed.

    摘要: A method to qualify access to a block storage device via augmentation of the device's controller and firmware flow. The method employs one or more block exclusion vectors (BEVs) that include attributes specifying allowed access operations for corresponding block address ranges. Logic in accordance with the BEVs is programmed into the controller for the block storage device, such as a disk drive controller for a disk drive. In response to an access request, a block address range corresponding to the storage block(s) requested to be accessed is determined. Based on the BEV entries, a determination is made to whether the determined logical block address range is covered by a corresponding BEV entry. If so, the attributes of the BEV are used to determine whether the access operation is allowed.
