**Linux Security: Iptables 防火墙终极指南** 本课程由一位经验丰富的 DevOps 工程师和专业培训师教授，旨在提供关于 Netfilter 和 Iptables 的全面深入的学习体验。无论您是 Linux 安全和 Iptables 的初学者，还是希望巩固已有知识的专业人士，本课程都能够满足您的需求。 **课程亮点：** * **内容全面：** 涵盖 Netfilter 和 Iptables 的所有核心主题，包括 Ipset、高级匹配和目标、NAT、端口转发、用户定义链等。 * **实用性强：** 拥有近 20 年 Linux 系统管理、安全工程和全栈开发经验的讲师，将“实战”经验融入教学。 * **易于理解：** 课程从基础开始，假设学员对 Netfilter、Iptables 和 Linux 防火墙是陌生的。 * **灵活学习：** 提供终身访问权限，可以随时回顾特定的 Iptables 匹配、目标或选项。 * **丰富资源：** 所有演示文稿和 Iptables 示例均可下载。 * **互动测验：** 包含大量测验，帮助学员检验和巩固所学知识。 **课程将带领您了解：** * Iptables 链（Chains）和表（Tables）的结构与遍历机制。 * Iptables 规则的组成部分。 * 使用 Ipset 高效过滤大量 IP 地址和网络。 * 根据国家/地区过滤流量。 * 各种 Iptables 匹配条件（IP、网络、端口、协议、网卡、MAC 地址、TCP 标志、日期时间、配额等）。 * Iptables 的各种目标（DROP、REJECT、ACCEPT、LOG、REDIRECT、TEE、SNAT、DNAT、MASQUERADE 等）。 * NAT（网络地址转换）和端口转发的配置。 * 利用 Shell 脚本实现防火墙自动化。 * Iptables 的最佳实践。 **学完本课程后，您将能够：** * 深入理解 Netfilter/Iptables 的架构。 * 掌握 Iptables 链和表的工作原理。 * 理解防火墙的运作机制。 * 创建复杂的 Iptables 规则，实现精细化的流量过滤。 * 记录恶意流量，并能有效防范 DoS 攻击。 * 利用 Ipset 轻松处理大规模 IP 列表，且不影响性能。 * 优化 Iptables 防火墙的性能。 * 通过 Shell 脚本实现防火墙安全任务的自动化。 * 熟练配置 NAT 和 MASQUERADE。 * 成功配置端口转发（DNAT）。 * 高效使用 Nmap 和 Netstat 工具。
This Iptables course covers every major topic related to Netfilter and Iptables including Ipset, advanced matches and targets, NAT, Fort Forwarding, user-defined chains, and many more!Welcome to the most complete and up-to-date course for learning and using Netfilter & Iptables Linux Firewall, taught by a DevOps Engineer and Professional Trainer.Just starting out with Linux Security and Iptables? Perfect. This course starts out assuming you're new to Netfilter, Iptables, and Linux Firewalls.Or maybe you've already tried to learn Iptables by yourself and now you want to put all the pieces together? Then, I'm here to help you! This course has everything you need to know about Netfilter and Iptables.You'll have lifetime access and you can return and look for a specific Iptables match, target or option anytime you want.All presentations and Iptables examples used in this course are available for download.The course contains many quizzes for you to take and test your knowledge.There are many courses on Linux Security or Iptables. Why should you learn from me?I'm a Practitioner and an Enthusiast. Welcome to the real world! I have almost 20 years of experience as a Linux Sysadmin, Security Engineer, and Full Stack Developer. I use Linux on a daily basis.I'm an Educator and I know how to make a syllabus. For the last 10 years, I've trained thousands of people on Linux, Networking, Security, or Programming.The topics covered in this course are:Iptables chains and tablesChains and tables traversalAnatomy of an iptables ruleFilter large collections of IPs and Networks using IpsetFilter traffic by countryIptables matches (implicit & explicit).Filter Traffic by IP, Network, Port, Protocol, Interface, MAC, TCP Flags, Date and Time, Quota, etc.Iptables targets: DROP, REJECT, ACCEPT, LOG, REDIRECT, TEE, SNAT, DNAT, MASQUERADE, etc.NATPort ForwardingAutomation using shell scriptsHow to use Iptables Best-PracticesEvery topic includes many live examples.After taking this course, you'll be able to:Have an In-Depth understanding of Netfilter/Iptables architecture.Understand Iptables chains and tables.Understand how a Firewall works.Create Iptables rules that filter incoming, outgoing, or routed traffic based on any possible criteria including the country the packet is coming from or destined to.LOG malicious traffic.Prevent DoS Attacks.Use Ipset to drop tens of thousands of Networks with no performance degradation.Optimize Iptables firewalls.Automate different firewall security tasks using shell scripts.Configure NAT and MASQUERADE.Configure Port Forwarding (DNAT).Use efficiently Nmap and Netstat.
