随着网络技术的不断发展和普及,随之而来的安全问题早已作为一项重要的课题被深入研究和探索。其中,缓冲区溢出攻击便是最为典型和最代表性的威胁之一,据相关资料研究表明,当前利用缓冲区溢出漏洞进行网络入侵的案例在所有攻击手段中占据70-80%的比例,已经成为网络安全最大隐患,因此,通过分析研究缓冲区溢出攻击的原理和运行机制,采取有效防御策略,对实现网络安全运行及维护具有现实意义。 With the continuous development and popularization of network technology, the ensuing security issues have long been studied and explored as an important issue. Among them, buffer overflow attacks are one of the most typical and most representative threats. According to relevant data studies, the current cases of network attacks using buffer overflow vulnerabilities occupy 70-80% of all attacks. Therefore, analyzing and studying the principle and operation mechanism of buffer overflow attacks and adopting effective defense strategies are of great significance to the realization of network security operation and maintenance.
