OverflowDungeon：一种新颖的溢出攻击防护系统

溢出攻击是网络上威胁最大的一种攻击方式，现有的防护技术存在不同的缺陷.本文提出并实现了一种新颖的防护机制，它从阻止溢出攻击产生破环性效果入手，抑制攻击行为.该方式不需要修改编译器，或修改操作系统，具有很高的实用性，它采用了统计方式，可有效防护Dummy return攻击技术.试验结果表明，系统不仅能有效地阻止溢出攻击，在效率方面相对于其他方式也有显著优势.

OverflowDungeon: A Novel Overflow Attack Prevention System

Overflow attack does the broadest harm to network applications. There are techniques which can prevent the kind of attack. However they have obvious flaws. This paper presents a novel mechanism of overflow attack prevention, which prevents shell code from exploiting resources of system. In this way, we need not change compiler or operating system. It uses statistic way to prevent dummy return trick. The implementation shows that it can prevent overflow attack and has advantage of performance over other mechanisms.
