Abstract

The embodiment of the invention provides a file protection method and device, equipment, a storage medium and a program product. The method comprises the following steps: if a currently operated first file is a file with a hard link, determining whether a tree structure corresponding to a first file path contains a node of the first file or not; if the tree structure corresponding to the first file path contains the node of the first file, performing target processing on the current operation; nodes in the tree structure are file nodes with hard links. According to the method provided by the embodiment of the invention, security protection is carried out on the operation of the file with the hard link, and the security is relatively high.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a file protection method, device, equipment, storage medium and program product. Background technique [0002] The rapid development of computer networks and mobile Internet applications has brought great convenience to social work and life, but the threats and losses caused by various network security issues are also increasing. For example, ransomware can destroy or encrypt files through write operations. [0003] In the process of implementing the solution of the present invention, the inventor found that the ransomware can write files through hard links. Therefore, how to protect against the write operation in the above hard link mode is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004] To solve the problems in the prior art, the embodiments of the present invention provide a file protection method, ...
