COMPUTER-IMPLEMENTED METHODS AND SYSTEM FOR PREVENTING UNAUTHORIZED FILE MODIFICATION BY MALICIOUS SOFTWARE AND THE LIKE

摘要

In some embodiments, a cyber security method for preventing unauthorized file modification by malicious software and the like, the file accessible to an authorized handler may include: receiving a first access request from a program, the first access request having a first instruction set for modifying data of the file; determining if the file is associated with the authorized handler; processing the first instruction set to produce first modification data; and generating an initial virtual file object comprising the first modification data. In further embodiments, a cyber security method for preventing unauthorized file modification by malicious software and the like, the file accessible to an authorized handler may include: processing an instruction set for modifying a file to produce modification data; generating a virtual file object comprising the modification data; and associating the virtual file object with the file by identifying the file as a sparse file.
