Research of defending buffer overflow exploits based on detecting and preventing shellcode
Zhang Tian-gang · Journal of Computer Applications · 2007
Buffer overflow exploits threat computer systems and the network security very seriously.The principles of buffer overflow exploit and shellcode were introduced first.Then the paper described the method of defending buffer overflow exploit based on detecting shellcode from several aspects including recognizing shellcode from the data types,rebasing modules to prevent shellcode from jumping to the shellcode,and disturbing the methods shellcode use to achieve malicious purposes.At last,advantages and disadvantages of these methods were analyzed and compared and the best of them was pointed out.Several measures were introduced to improve system security more comprehensively.
