"《Secure Coding in C and C++》由Robert Seacord撰写,是一本专注于C和C++安全编码的教材。书中深入探讨了可能导致安全缺陷的基本编程错误,如字符串、指针、动态内存管理、整数、格式化输出和文件I/O等方面的漏洞,并提供了解决和预防这些错误的方法,旨在提升软件的安全性,抵御潜在的恶意攻击。" 《Secure Coding in C and C++》是针对C和C++程序员以及软件安全工程师的重要参考书籍。作者通过对过去十年近18000份漏洞报告的分析,指出了少数根本原因导致了大部分安全漏洞的发生。书中不仅解释了这些错误,还演示了它们如何被利用以及可能造成的后果,同时提出了安全的替代实践,帮助开发者构建更安全的代码,从而抵御当前和未来的攻击。 在第1章中,Seacord介绍了软件安全的背景,强调了衡量危险的重要性,包括损失的现状、威胁的来源以及安全策略。他还讨论了C和C++的历史,指出这两个语言中存在的问题,特别是遗留代码可能带来的安全隐患。此外,他还涵盖了开发平台,如操作系统和编译器的选择,这些都会影响到软件的安全性。 书中的内容涵盖了以下几个关键领域: 1. **不安全的字符串操作**:包括缓冲区溢出,这是许多安全漏洞的根源,可能导致代码执行、数据泄露或其他严重后果。 2. **指针错误**:误用指针可能导致悬挂指针、空指针解引用,甚至内存泄漏,这些都可能被攻击者利用。 3. **动态内存管理**:不当的内存分配和释放可能导致内存泄漏或双重释放,为攻击者创造机会。 4. **整数处理**:整数溢出或下溢可能导致计算错误,影响程序的行为,有时也可能被用于攻击。 5. **格式化输出**:不安全的格式字符串使用可能导致信息泄露或控制流劫持。 6. **文件I/O**:错误的文件操作可能导致数据泄露或权限提升。 通过学习本书,开发者可以了解到如何避免这些常见错误,采用最佳的安全实践,例如使用安全的函数库,进行边界检查,以及正确管理内存和文件操作。书中提供的案例分析和解决策略有助于程序员在日常开发中养成安全编程的习惯,从而提高软件的整体安全性。 这本书对于任何希望提高其C/C++项目安全性的开发者来说都是宝贵的资源,它提醒我们,软件安全不应被视为事后诸葛亮,而应是开发过程的核心部分。通过深入理解和应用书中的原则,开发者可以编写出更健壮、更安全的代码,减少系统被攻击的可能性。

Learn the Root Causes of Software Vulnerabilities and How to Avoid Them Commonly exploited software vulnerabilities are usually caused by avoidable software defects. Having analyzed tens of thousands of vulnerability reports since 1988, CERT has determined that a relatively small number of root causes account for most of the vulnerabilities. Secure Coding in C and C++, Second Edition, identifies and explains these root causes and shows the steps that can be taken to prevent exploitation. Moreover, this book encourages programmers to adopt security best practices and to develop a security mindset that can help protect software from tomorrow’s attacks, not just today’s. Drawing on the CERT’s reports and conclusions, Robert C. Seacord systematically identifies the program errors most likely to lead to security breaches, shows how they can be exploited, reviews the potential consequences, and presents secure alternatives. Coverage includes technical detail on how to Improve the overall security of any C or C++ application Thwart buffer overflows, stack-smashing, and return-oriented programming attacks that exploit insecure string manipulation logic Avoid vulnerabilities and security flaws resulting from the incorrect use of dynamic memory management functions Eliminate integer-related problems resulting from signed integer overflows, unsigned integer wrapping, and truncation errors Perform secure I/O, avoiding file system vulnerabilities Correctly use formatted output functions without introducing format-string vulnerabilities Avoid race conditions and other exploitable vulnerabilities while developing concurrent code The second edition features Updates for C11 and C++11 Significant revisions to chapters on strings, dynamic memory management, and integer security A new chapter on concurrency Access to the online secure coding course offered through Carnegie Mellon’s Open Learning Initiative (OLI) Secure Coding in C and C++, Second Edition, presents hundreds of examples of secure code, insecure code, and exploits, implemented for Windows and Linux. If you’re responsible for creating secure C or C++ software–or for keeping it safe–no other book offers you this much detailed, expert assistance.
