Abstract

A method and a related system for a protection against unauthorized file encryption in a file system may be provided. The method may comprise providing an anti-ransomware file access unit, determining, by the anti-ransomware file access unit, an entropy value for a portion of a file to be written to the file system, and upon determining that the entropy value is equal or above a threshold value, performing a copy-on-write process to the file to be written, whereby the file is written to a copy-on-write storage area.
