Linux Network Security

Description:

Linux networks are becoming more and more common, but security is often an overlooked issue. Unfortunately, in today‚s environment all networks are potential hacker targets, from top-secret military research networks to small home LANs. Linux Network Security focuses on securing Linux in a networked environment, where the security of the entire network needs to be considered rather than just isolated machines. It uses a mix of theory and practical techniques to teach administrators how to install and use security applications, as well as how the applications work and why they are necessary. Starting with the need for security and understanding the problem, the book teaches administrators about packet filtering (firewalling) with iptables, hardening services such as Apache, BIND, Sendmail, FTP, and MySQL to prevent attacks, network analysis, encryption, local security, DoS attacks, and rootkits. Auditing networks for potential vulnerabilities and creating secure passwords is also explored. This is the one book that really details how to secure a Linux network.

描述：
Linux網絡越來越普遍，但安全問題往往被忽視。不幸的是，在今天的環境中，所有網絡都是潛在的黑客目標，從最高機密的軍事研究網絡到小型家庭局域網。《Linux網絡安全》專注於在網絡環境中保護Linux，需要考慮整個網絡的安全，而不僅僅是單獨的機器。它結合了理論和實踐技巧，教導管理員如何安裝和使用安全應用程序，以及這些應用程序的工作原理和必要性。從安全需求和問題的理解開始，本書教導管理員使用iptables進行封包過濾（防火牆），加固Apache、BIND、Sendmail、FTP和MySQL等服務以防止攻擊，進行網絡分析、加密、本地安全、DoS攻擊和rootkits。還探討了對潛在漏洞進行網絡審計和創建安全密碼。這是一本真正詳細介紹如何保護Linux網絡的書籍。
