Embodiment Construction

[0024] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0025] At present, the main ways to prevent illegal codes include static scanning of disk files, process-based memory static scanning, patching, and firewall-based security policy protection. These security protection strategies are all implemented based on the known illegal code. For example, static scanning of disk files is the full-disk and directory scanning of common antivirus software. Process-based memory static scanning is common antivirus software scanning the memory of user processes and operating system processes. Firewall-based security policy protection is to protect some Protocols and ports are blocked.

[0026] That is to say, these network security protection measures can work only on the premis...

Abstract

The invention discloses an illegal code identification method, system, device and storage medium, and relates to the computer field. The method includes: obtaining the code, recording the execution characteristics of the code; writing the code into the executable memory, and recording the write operation data; before executing the code, judging the static consistency or dynamic continuation of the code according to the execution characteristics and the write operation data Whether sex is legal. The invention realizes the identification of unknown codes, realizes more accurate memory protection, does not need to wait for the release of patches, can realize blocking protection before code execution, and has stronger protection.

Description

technical field [0001] The invention relates to the computer field, in particular to an illegal code identification method, system, device and storage medium. Background technique [0002] At present, the main ways to prevent illegal codes include static scanning of disk files, process-based memory static scanning, patching, and firewall-based security policy protection. However, the current prevention method is only to scan and kill known viruses or attack codes, and cannot identify unknown illegal codes, and cannot discover the memory implantation and operation of unknown malicious codes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an illegal code identification method, system, device and storage medium for the deficiencies of the prior art. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] A method for identifying ille...
