Cybersecurity for Beginners is an engaging introduction to the field of cybersecurity. You'll learn how attackers operate, as well as how to defend yourself and organizations against online attacks.

You don’t need a technical background to understand core cybersecurity concepts and their practical applications – all you need is this book. It covers all the important stuff and leaves out the jargon, giving you a broad view of how specific attacks work and common methods used by online adversaries, as well as the controls and strategies you can use to defend against them.
 
Each chapter tackles a new topic from the ground up, such as malware or social engineering, with easy-to-grasp explanations of the technology at play and relatable, real-world examples. Hands-on exercises then turn the conceptual knowledge you’ve gained into cyber-savvy skills that will make you safer at work and at home. You’ll explore various types of authentication (and how they can be broken), ways to prevent infections from different types of malware, like worms and viruses, and methods for protecting your cloud accounts from adversaries who target web apps.
 
You’ll also learn how to:
  •  Use command-line tools to see information about your computer and network
  •  Analyze email headers to detect phishing attempts
  •  Open potentially malicious documents in a sandbox to safely see what they do
  •  Set up your operating system accounts, firewalls, and router to protect your network
  •  Perform a SQL injection attack by targeting an intentionally vulnerable website
  •  Encrypt and hash your files
 

In addition, you’ll get an inside look at the roles and responsibilities of security professionals, see how an attack works from a cybercriminal’s viewpoint, and get first-hand experience implementing sophisticated cybersecurity measures on your own devices.

网络安全入门》是对网络安全领域的一个引人入胜的介绍。你将学习攻击者如何运作，以及如何保护自己和组织免受在线攻击。

你不需要有技术背景就能理解核心的网络安全概念及其实际应用--你所需要的就是这本书。本书涵盖了所有重要的内容，并抛开了专业术语，让你对具体的攻击如何运作和网上对手使用的常见方法有一个广泛的认识，以及你可以用来防御它们的控制和策略。

每一章都从头开始处理一个新的主题，如恶意软件或社会工程，对起作用的技术进行易于理解的解释，并举出与现实世界相关的例子。实践练习将你获得的概念性知识转化为网络知识技能，使你在工作和家庭中更加安全。你将探索各种类型的认证（以及它们如何被破解），防止不同类型的恶意软件（如蠕虫和病毒）感染的方法，以及保护你的云账户免受针对网络应用的对手攻击的方法。

你还将学习如何。

  - 使用命令行工具查看有关您的计算机和网络的信息

  - 分析电子邮件的标题，以发现网络钓鱼的企图

  - 在沙盒中打开潜在的恶意文件，安全地查看它们的作用

  - 设置你的操作系统账户、防火墙和路由器以保护你的网络

  - 通过瞄准一个故意脆弱的网站进行SQL注入攻击

  - 对你的文件进行加密和散列

此外，你将深入了解安全专业人员的角色和责任，从网络犯罪者的角度看攻击是如何进行的，并获得在自己的设备上实施复杂的网络安全措施的第一手经验。
