A remote buffer overflow vulnerability detection model and system

Need to be testing the software system source code. Run-time location of the injection into the SWWI typically include memory space,[link widoczny dla zalogowanych], system calls and network layers. The system run-time through the network layer technology SWIFI remote buffer overflow detection. Software remote buffer overflow vulnerability occurs because the input string using the network or other fixed-length binary data length and effectiveness have not done before the inspection,[link widoczny dla zalogowanych], thus can determine the error injection network layer for the network data flow injection point the length of the strings and other variable data. Use of open communication protocol software is very easy to determine the injection point, for the use of proprietary communication protocol software,[link widoczny dla zalogowanych], need to use technical analysis pattern recognition software to detect the network data stream to determine the fault injection points. Determine the injection point,[link widoczny dla zalogowanych], the combination of vulnerability knowledge base generates 62 feet into the complete fault injection. 5 System model to test the usability test, the detection capability of this model was tested. The program detected, including two written tests for the system with remote buffer overflow vulnerability procedures there has been an open process remote buffer overflow vulnerability and a vulnerability not know in advance whether the procedure. Results in Table 1. The results in Table 1 whether the source of the program name vulnerability type Closing loopholes detected buffer overflow vulnerability detection and other methods, the proposed detection model specifically designed to detect remote buffer overflow vulnerability has correctly reported that no source code and so on. System testing and practical application show that the fault injection technique based on a remote buffer overflow vulnerability detection system can detect the preparation for system testing remote buffer overflow vulnerability, but also commercial software can detect known and unknown vulnerabilities.
