    摘要： To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, a sector map is accessed. The sector map identifies one or more sectors of a storage volume and also identifies, for each of the one or more sectors of the storage volume, a signature of the content of the sector. In response to a request to read the content of a sector, the content of the sector is returned without decrypting the content if the sector is one of the one or more sectors and the signature of the content of the sector matches the signature of the sector identified in the sector map. Otherwise, the content of the sector is decrypted and the decrypted content is returned.

    摘要： To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, an encrypted chunks map is accessed. The encrypted chunks map identifies whether, for each chunk of sectors of a storage volume, the sectors in the chunk are unencrypted. In response to a request to write content to a sector, the encrypted chunks map is checked to determine whether a chunk that includes the sector is unencrypted. If the chunk that includes the sector is unencrypted, then the sectors in the chunk are encrypted, and the content is encrypted and written to the sector. If the chunk that includes the sector is encrypted or not in use, then the content is encrypted and written to the sector.

    摘要： In a pre-operating system environment on a device prior to loading and running an operating system on the device, a policy identifying configuration settings for the operating system is obtained. The operating system itself is prevented from changing this policy, but the policy can be changed under certain circumstances by components of the pre-operating system environment. The policy is compared to configuration values used by the operating system, and the operating system is allowed to boot with the configuration values if the configuration values satisfy the policy. However, if the configuration values do not satisfy the policy, then a responsive action is taken.
