Securing communication using function extraction technology for malicious code behavior analysis

Since computer hardware and Internet is growing so fast today, security threats of malicious executable code are getting more serious. Basically, malicious executable codes are categorized into three kinds – virus, Trojan Horse, and worm. Current anti-virus products cannot detect all the malicious codes, especially for those unseen, polymorphism malicious executable codes. The newly developed virus will create the damages before it has been found and updated in database. The basic idea of the proposed system is, it will analyze the behavior of the malicious codes and based on the behavior signature of the malicious code content filtering mechanism will be used to filter out contents, so that, the system will be secured from the future communication processes. The behavior of the code is analyzed using the function extraction technology. The function extraction technology will replace the function codes into algebraic expressions. Based on the behavior of the malicious codes, it will be categorized into different kinds of malicious codes. The detected malicious code will be prevented from execution. Based on the type of malicious code, appropriate security mechanism will be used for further communication.
