Abstract: A method for defending a computing system against ransomware attacks is disclosed. In one embodiment, such a method includes identifying, on a computing system, files to be protected against ransomware attacks. The method appends a public key to each of the files. Upon receiving a request to modify a specific file, the method reads the public key appended to the file, requests an authentication token from a user, and computes a private key associated with the files. The method combines the public key, authentication token, and private key to generate an unlock key. This unlock key is compared to a validation key. The method authorizes modification of the file in the event the unlock key matches the validation key. A corresponding system and computer program product are also disclosed.

Abstract: Embodiments of the present invention provides methods, computer program products, and a system for improving serial performance of a computer system storage volume. Embodiments of the present invention can be used to reduce a partition scheme of a storage volume to allow for a computer system to read the storage volume using additional system resources that were previously idle during a serial read operation. Embodiments of the present invention can be used to reserve random-access memory (RAM) to store metadata describing data stored on a storage volume that utilizes a reduced partition scheme. Once the serial read of the storage volume is complete, the embodiments of the present invention can revert the partition scheme back to the original partition scheme for normal, non-serial read operations.
