Disclosed are systems and method or updating full disk encryption (FDE) software on a computer. An example method comprises: obtaining an updated version of the FDE software; blocking operations of the FDE software on a boot drive of the computer; updating one or more components of the FDE software based on the updated version of the FDE software; modifying a booting process of an operating system of the computer to allow execution of a new version of a pre-boot compatibility verification component before the booting process; executing the new version of the pre-boot compatibility verification component, without decrypting and encrypting data on the boot drive, to determine if the boot drive is compatible with the updated FDE software; and if the boot drive is determined to be compatible with the updated FDE software, performing the booting process of the operating system of the computer.

System and method updating disk encryption software and performing pre-boot compatibility verification

Disclosed are systems and method or updating full disk encryption (FDE) software on a computer. An example method comprises: blocking operations of the FDE software on a boot drive of the computer; installing one or more components of the updated FDE software; deploying an updated pre-boot compatibility verification component of updated FDE software; rebooting the computer and executing, before booting of an operating system, the updated pre-boot compatibility verification component; determining, by the updated pre-boot compatibility verification component, a compatibility of the boot disk with the updated FDE software without decrypting and encrypting the boot disk of the computer by the updated FDE software; if the boot disk is determined to be compatible with the updated FDE software, authenticating a computer user and booting the operating system of the computer; and unblocking one or more operations of the updated FDE software on the boot drive.

System and method updating full disk encryption software

Disclosed are systems, methods and computer program products for encryption of disk based on pre-boot compatibility testing. An example method includes upon determining, by a processor, no test booting of the computer, performing one or more pre-boot compatibility tests to boot an operating system of the computer; upon detecting a successful test booting, performing booting the operating system of the computer or performing the one or more pre-boot compatibility tests again; upon detecting an unsuccessful test booting, restoring a process of ordinary booting of the operating system and performing an ordinary booting of the operating system; determining one or more encryption policies applicable to a pre-boot execution stage of the computer; and comparing results of the one or more pre-boot compatibility tests with the encryption policies to determine whether to apply a full disk encryption to the boot disk.

System and method for encryption of disk based on pre-boot compatibility testing

Disclosed are systems, methods and computer program products for full disk encryption of a boot disk of a computer. One example method for full disk encryption of a boot disk of a computer includes performing one or more pre-boot compatibility tests on the boot disk of the computer; determining one or more encryption policies applicable to a pre-boot execution stage of the computer; comparing results of the pre-boot compatibility tests with the encryption policies; determining whether to apply a full disk encryption to the boot disk based on an outcome of comparing the results of the pre-boot compatibility tests with the encryption policies; and when it is determined to apply the full disk encryption, applying the full disk encryption to the boot disk.
