Buffer overflow attacks are serious security threats to modern computer systems. Prior works against buffer overflow attacks may require users to patch the source codes, rebuild programs, modify the operating system or the augments of hardware architecture, and thus often result in performance ...
1) protection against buffer overflow 抗缓冲区溢出攻击机制 1. A new architecture for embedded network security system is proposed and a multi-levelprotection against buffer overflowis expounded. 在分析了缓冲区溢出的基本原理以及抗缓冲区溢出攻击的方法后,提出建立全新的嵌入式网络安全设备的安全架构,并构建...
GuardStack is designed to mitigate only a specific type of vulnerability, namely stack buffer overflow. More important, using GuardStack by itself against this vulnerability may not provide a high degree of protection because there are ways for an attacker to go around it:...
Efficient protection against heap-based buffer overflows without resorting to magic - Younan, Joosen, et al. - 2006 () Citation Context ...ection attacks. Our prototype implementation (which we call dnmalloc) comes at a very modest cost in both performance and memory usage overhead. This ...
A POP buffer overflow attack occurs when a remote attacker attempts to gain root access of a POP server by overflowing an internal buffer on the server. ISA Server Preconfigured Attack Protection ISA Server includes preconfigured protection against specific attacks. This includes spoof detection and br...
Data execution prevention (DEP) prevents memory that wasn't explicitly allocated as executable from being executed. DEP helps protect against an attacker injecting malicious code into the process, such as through a buffer overflow, and then executing that code. ...
2.9.9 Buffer Overflow Attack Mitigation Starting with the 2.6.x kernel releases, Linux offers Address Space Layout Randomization (ASLR) and the No-eXecute (NX bit) for mitigation of buffer overflow attacks. For more information, see:

Though StackGuard may be effective in preventing stack-buffer overflow attacks it has certain limitations as well: An information disclosure flaw in a different part of the program could disclose the global __stack_chk_guard value. This would allow an attacker to write the correct canary value ...
