SYSTEM FOR QUARANTINING MALICIOUS CODE USING STRING METATHESIS AND METHOD THEREFOR

摘要

PURPOSE: A malicious code preventing system and method thereof are provided to prevent the insertion of a malicious code within a file by automatically inserting a character string of a source code. CONSTITUTION: A malicious code blocking server(100) indexes stored files and extracts a source code that is inserted in the indexed files. The malicious code blocking server classifies the character string that is inserted into the source code. If the security code is not inserted into the character string, the malicious code blocking server inserts the security code into the character string. The malicious code blocking server transmits the security code to a security server(200).
