Abstract
During the startup of an operating system of a computing system, a monitoring process of the operating system is used to detect an entry point of a daemon manager process. In response to detecting the entry point, the startup process is paused, and an early attach process is launched so as to attach one or more encrypted data partitions to the operating system. As part of the early attach process, the network stack of the computing system may be initialized, which allows the early attach process to retrieve one or more decryption keys corresponding to the one or more encrypted data partitions from an external key management server. The one or more decryption keys may be transmitted to a disk filter driver of the operating system, which provides the operating system with access to the one or more encrypted data partitions. Upon the conclusion of the early attach process, the operating system startup process resumes with the one or more encrypted data partitions now accessible to the operating system.
