Abstract

The invention discloses a method and a system for safely running an executable file. The method comprises the steps of: when it is detected that the executable file is called, obtaining an executablefile, the calling main body of the executable file and the operation instruction of the calling main body to the executable file, when it is determined that the operation instruction of the calling main body on the executable file is valid; further verifying whether the executable file, the calling main body and the operation instruction exist in a preset ACL or not; verifying whether the executable file is tampered or not and whether the digital signature of the executable file is credible or not by matching the digital signature of the executable file with the digital signature of the executable file corresponding to the ACL, loading the executable file only when all verification passes, and starting a new process to run the executable file. Before the executable file is operated, the executable file is verified for multiple times, the executable file carrying viruses and / or malicious programs is filtered out, and safe operation of the executable file is achieved.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a method and system for safely running executable files. Background technique [0002] With the integration of industrialization and informatization in the national grid, and the rapid development of network communication technology in recent years, while the network application is developing vigorously, the openness of the network has also brought huge security risks, and there is a risk of being attacked by viruses. As computer viruses have gradually evolved from being highly dependent on "zero-day" vulnerabilities to highly customized special viruses that do not rely on "zero-day" vulnerabilities, how to intercept viruses has become an important condition to ensure the safe operation of the power Internet of Things. [0003] At present, the virus interception method is mainly the virus feature detection technology, and the virus is targeted to be intercepted by ...
