Abstract

The invention discloses a file protection method and apparatus. The method includes: determining a program for initiating an operation instruction when the operation instruction for a file is monitored; determining a classification program white list corresponding to the file type according to the file type of the file; and determining whether the program for initiating the operation instruction belongs to the classification program white list, and determining whether the file is protected according to a determination result. In usual conditions, the application programs matched with the file types of the files are responsible for processing of the files of each type so that whether the protection of the file needs to be reinforced can be rapidly and accurately determined by monitoring whether the program of the operation file is matched with the file type of a to-be-operated file, and the security of the files is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a file protection method and device. Background technique [0002] With the development of computer technology, informatization has developed rapidly in all walks of life. For enterprises and institutions, network paperless office is becoming more and more popular, therefore, the importance of electronic documents is becoming increasingly prominent. [0003] In order to seek illegal benefits, computer hackers often launch various types of attacks on electronic files. For example, hackers can use malicious programs to encrypt electronic files and other illegal operations without the user's permission, so that the user cannot normally use the illegally operated electronic file, thereby causing huge losses to the user. Therefore, how to quickly and effectively identify malicious programs and prevent malicious programs from performing illegal operations on electronic files has be...
