Hardware-based Technology to Prevent Buffer Overflow Attacks on Windows System——DEP;

Overflow attack does the broadest harm to network applications.

This technique,which consists of instrumenting a given executable with a mechanism to detect stack smashing attacks,works at install-time and does not rely on having access to the source-code.

Stack smashing is still one of the most popular techniques for computer system attack.

Research on Principle and Defense of Buffer Overflow Attacks;

Combining with the principles of the produce to buffer overflow attack,this paper analyzes the structure of buffer overflow attack codes,and describes the Snort rules used for buffer overflow attack inspection.

Undoubtedly, in this networked information era, these bugs make the Buffer Overflow Attack very easy propagate, it threatens the systematic security greatly.

This paper analyzes the principle of the buffer overflow attacks,discusses the modes based on buffer overflow attacks,implantation code and general laws so as to put forward some preventive strategies and measures.

In this paper,from programming point of view,the buffer overflow attacks are analyzed and the methods of avoiding buffer overflow at the stage of source code are introduced.

This paper analyses the most commonly used methods on buffer overflow defense and presents a new detecting method of buffer overflow attacks based on address confirmation ,starting by analyzing the principle of buffer overflow attacks.
