关于 Udemy 上的道德黑客攻击的常见问题解答

什么是道德黑客，它的用途是什么？
道德黑客攻击涉及黑客与授权黑客对系统或网络进行网络攻击以暴露潜在漏洞的组织或个人达成一致。道德黑客有时也被称为白帽黑客。许多人依靠道德黑客来识别其网络、端点、设备或应用程序中的弱点。黑客通知他们的客户他们何时会攻击系统，以及攻击的范围。道德黑客在与客户达成协议的范围内运作。他们无法努力发现漏洞，然后要求付款以修复它们。这就是灰帽黑客所做的。道德黑客也不同于黑帽黑客，黑帽黑客在未经许可的情况下进行黑客攻击以伤害他人或使自己受益。

道德黑客是个好职业吗？
是的，道德黑客是一个很好的职业，因为它是测试网络的最佳方法之一。道德黑客试图通过测试不同的黑客技术来定位网络中的漏洞。在许多情况下，网络似乎无法渗透只是因为它多年来没有屈服于攻击。然而，这可能是因为黑帽黑客使用了错误的方法。有道德的黑客可以通过发起一种前所未有的新型攻击来向公司展示他们是如何脆弱的。当他们成功渗透系统时，组织可以设置防御措施来防止这种渗透。这种独特的安全机会使道德黑客的技能对于希望确保其系统能够抵御网络犯罪分子的组织来说是理想的。

道德黑客需要了解哪些技能？
除了熟练掌握基本的计算机技能和命令行的使用外，道德黑客还必须培养与编程、数据库管理系统 (DBMS)、Linux 操作系统 (OS) 的使用、密码学、网络创建和管理相关的技术技能应用程序和计算机网络，例如 DHCP、NAT 和子网。成为一名道德黑客需要学习至少一种编程语言并具备其他常用语言（如 Python、SQL、C++ 和 C）的工作知识。道德黑客必须具备强大的解决问题的能力和批判性思考的能力，才能提出和测试用于保护系统的新解决方案。道德黑客还应该了解如何使用逆向工程来发现规范并通过分析系统代码来检查系统是否存在漏洞。

黑客为什么要使用 Linux？
许多黑客使用 Linux 操作系统 (OS)，因为 Linux 是一个免费和开源的操作系统，这意味着任何人都可以修改它。访问和自定义 Linux 的所有部分都很容易，这使黑客可以更好地控制操作系统。Linux 还具有集成良好的命令行界面，为用户提供比许多其他系统提供的更精确的控制级别。虽然 Linux 被认为比许多其他系统更安全，但一些黑客可以修改现有的 Linux 安全发行版，将它们用作黑客软件。大多数道德黑客更喜欢 Linux，因为它被认为比其他操作系统更安全，并且通常不需要使用第三方防病毒软件。道德黑客必须精通Linux，才能发现漏洞并打击恶意黑客，

道德黑客是否合法？
是的，道德黑客行为是合法的，因为黑客拥有测试系统漏洞的完全、明确的许可。道德黑客在其工作的个人或组织规定的限制范围内运作，本协议规定了法律安排。道德黑客就像为汽车制造商处理质量控制的人。他们可能不得不尝试破坏车辆的某些部件，例如挡风玻璃、悬架系统、变速箱或发动机，以查看它们的弱点或如何改进它们。通过道德黑客攻击，黑客正试图“破坏”系统，以确定它如何降低网络攻击的脆弱性。但是，如果道德黑客在未经所有者明确许可的情况下攻击网络或计算机的某个区域，则他们可能被视为灰帽黑客，

什么是认证道德黑客 (CEH) 认证考试？
Certified Ethical Hacker (CEH) 认证考试支持和测试审计员、安全人员、站点管理员、安全专业人员以及任何希望确保网络安全免受网络犯罪分子侵害的任何人的知识。使用 CEH 证书，您可以设计和管理安全专业人员参与道德黑客活动所需的证书信息的最低标准。如果获得 CEH 证书的人达到或超过了最低标准，您也可以将其公之于众。您还有权加强道德黑客的实用性和自我监管性质。CEH 考试不迎合特定的安全硬件或软件供应商，例如 Fortinet、Avira、Kaspersky、Cisco 或其他供应商，使其成为供应商中立计划。

什么是认证信息安全经理 (CISM) 考试？
通过认证信息安全经理 (CISM) 考试表明获得认证的个人是信息安全治理、开发和管理安全计划以及管理事件和风险方面的专家。对于被视为“认证”的人，他们必须在过去五年内通过考试，并且在相关职业中全职工作，例如信息安全和 IT 管理。该考试测试个人对不同系统面临的风险、如何开发评估和减轻这些风险的计划以及如何确保组织的信息系统符合内部和监管政策的知识。该考试还评估一个人如何使用工具帮助组织从成功的攻击中恢复。

有哪些不同类型的黑客？
不同类型的黑客包括白帽黑客，他们是道德黑客，被授权入侵系统，黑帽黑客是网络犯罪分子，灰帽黑客介于两者之间，可能不会破坏您的系统，而是为了个人利益而进行黑客攻击。还有直接攻击黑帽黑客的红帽黑客。有些人称新黑客为绿帽黑客。这些人渴望成为成熟的、受人尊敬的黑客。国家资助的黑客为国家和黑客活动家工作，并利用黑客技术来支持或推广一种哲学。有时，黑客可以充当举报人，入侵自己的组织以揭露隐藏的做法。还有脚本小子和蓝帽黑客。一个脚本小子试图通过启动脚本和下载工具来关闭网站和网络来给他们的朋友留下深刻印象。

关于 Udemy 渗透测试的常见问题解答

什么是渗透测试？
渗透测试或渗透测试是攻击企业网络以发现任何可能存在的漏洞以进行修补的过程。道德黑客和安全专家执行这些测试，以在恶意黑客发现并利用它们之前发现系统安全性中的任何弱点。以前对系统安全性一无所知的人通常会执行这些测试，从而更容易发现开发团队可能忽略的漏洞。您可以使用手动或自动技术执行渗透测试，以破坏服务器、Web 应用程序、无线网络、网络设备、移动设备和其他暴露点。

渗透测试有哪些不同类型？
渗透测试有很多种。内部渗透测试测试企业的内部网络。该测试可以确定员工可能造成的损害程度。外部渗透测试针对公司的面向外部的技术，例如他们的网站或网络。公司使用这些测试来确定匿名黑客如何攻击系统。在隐蔽渗透测试（也称为双盲渗透测试）中，公司中很少有人会知道正在进行渗透测试，包括任何安全专业人员。这种类型的测试不仅会测试系统，还会测试公司对主动攻击的响应。通过封闭式渗透测试，黑客可能对受到攻击的企业一无所知，只知道其名称。在开箱测试中，

渗透测试的不同阶段是什么？
渗透测试有五个不同的阶段。第一阶段定义测试的目标和范围以及将使用的测试方法。安全专家还将收集有关公司系统的情报，以更好地了解目标。渗透测试的第二阶段是扫描目标应用程序或网络以确定它们将如何响应攻击。您可以通过对应用程序代码的静态分析以及对正在运行的应用程序和网络的动态扫描来做到这一点。第三阶段是攻击阶段，在最后阶段发现的可能漏洞被各种黑客方法攻击。在渗透测试的第四阶段，测试人员试图保持对系统的访问，以窃取任何敏感数据或破坏系统。渗透测试的第五个也是最后一个阶段是报告阶段，

由于使用免费工具和平台，您无需购买任何工具或应用程序。

您将通过动手实践找出和利用最常见的漏洞，例如 SQL 注入、XSS（跨站点脚本）和 CSRF（跨站点请求伪造）。

在开始学习如何“合乎道德地”破解网站之前，您将学习如何设置实验室环境并安装所需的虚拟机，例如 Kali Linux 和 OWASP Broken Web Applications。这将允许您“安全地”练习和破解，而不会影响您的主要系统。

然后，您将学习 Web 应用程序的基本术语、标准、技术和协议：HTML、URL、HTTP 等。

当您准备好开始黑客攻击时，您将开始收集信息。此外，您将学习如何使用搜索引擎找出网站中是否存在已知漏洞。在发现网站时，您将分析配置以了解它们是否会导致任何漏洞。

然后，您将学习破解 Web 应用程序最重要的部分：如何操作输入字段和应用程序产生的输出。您将在本节中看到最著名和最危险的漏洞，包括 SQL 注入和跨站点脚本 (XSS)。

您不仅将学习如何找出漏洞，还将学习如何利用和破解这些弱点。此外，还将教授防止黑客攻击这些弱点的方法。

之后，您将学习如何发现授权、身份验证和会话管理缺陷。您将学习如何使用暴力攻击查找用户名和密码、如何修复会话、如何提升权限、如何发现和利用跨站请求伪造 (CSRF) 等等。

在本课程中，您将找到干净纯粹的信息。在准备培训时，我们特别避免了不必要的谈话和等待；我们已经为您找到了这些部件并将它们取出。

FAQ regarding Ethical Hacking on Udemy

What is Ethical Hacking and what is it used for ?
Ethical hacking involves a hacker agreeing with an organization or individual who authorizes the hacker to levy cyber attacks on a system or network to expose potential vulnerabilities. An ethical hacker is also sometimes referred to as a white hat hacker. Many depend on ethical hackers to identify weaknesses in their networks, endpoints, devices, or applications. The hacker informs their client as to when they will be attacking the system, as well as the scope of the attack. An ethical hacker operates within the confines of their agreement with their client. They cannot work to discover vulnerabilities and then demand payment to fix them. This is what gray hat hackers do. Ethical hackers are also different from black hat hackers, who hack to harm others or benefit themselves without permission.

Is Ethical Hacking a good career?
Yes, ethical hacking is a good career because it is one of the best ways to test a network. An ethical hacker tries to locate vulnerabilities in the network by testing different hacking techniques on them. In many situations, a network seems impenetrable only because it hasn’t succumbed to an attack in years. However, this could be because black hat hackers are using the wrong kinds of methods. An ethical hacker can show a company how they may be vulnerable by levying a new type of attack that no one has ever tried before. When they successfully penetrate the system, the organization can then set up defenses to protect against this kind of penetration. This unique security opportunity makes the skills of an ethical hacker desirable for organizations that want to ensure their systems are well-defended against cybercriminals.

What skills do Ethical Hackers need to know?
In addition to proficiency in basic computer skills and use of the command line, ethical hackers must also develop technical skills related to programming, database management systems (DBMS), use of the Linux operating system (OS), cryptography, creation and management of web applications and computer networks like DHCP, NAT, and Subnetting. Becoming an ethical hacker involves learning at least one programming language and having a working knowledge of other common languages like Python, SQL, C++, and C. Ethical hackers must have strong problem-solving skills and the ability to think critically to come up with and test new solutions for securing systems. Ethical hackers should also understand how to use reverse engineering to uncover specifications and check a system for vulnerabilities by analyzing its code.

Why do hackers use Linux?
Many hackers use the Linux operating system (OS) because Linux is a free and open-source OS, meaning that anyone can modify it. It’s easy to access and customize all parts of Linux, which allows a hacker more control over manipulating the OS. Linux also features a well-integrated command-line interface, giving users a more precise level of control than many other systems offer. While Linux is considered more secure than many other systems, some hackers can modify existing Linux security distributions to use them as hacking software. Most ethical hackers prefer Linux because it’s considered more secure than other operating systems and does not generally require the use of third-party antivirus software. Ethical hackers must be well-versed in Linux to identify loopholes and combat malicious hackers, as it’s one of the most popular systems for web servers.

Is Ethical Hacking Legal?
Yes, ethical hacking is legal because the hacker has full, expressed permission to test the vulnerabilities of a system. An ethical hacker operates within constraints stipulated by the person or organization for which they work, and this agreement makes for a legal arrangement. An ethical hacker is like someone who handles quality control for a car manufacturer. They may have to try to break certain components of the vehicle such as the windshield, suspension system, transmission, or engine to see where they are weak or how they can improve them. With ethical hacking, the hacker is trying to “break” the system to ascertain how it can be less vulnerable to cyberattacks. However, if an ethical hacker attacks an area of a network or computer without getting expressed permission from the owner, they could be considered a gray hat hacker, violating ethical hacking principles.

What is the Certified Ethical Hacker ( CEH ) Certification Exam?
The Certified Ethical Hacker (CEH) certification exam supports and tests the knowledge of auditors, security officers, site administrators, security professionals, and anyone else who wants to ensure a network is safe against cybercriminals. With the CEH credential, you can design and govern the minimum standards necessary for credentialing information that security professionals need to engage in ethical hacking. You can also make it known to the public if someone who has earned their CEH credentials has met or exceeded the minimum standards. You are also empowered to reinforce the usefulness and self-regulated nature of ethical hacking. The CEH exam doesn’t cater to specific security hardware or software vendors, such as Fortinet, Avira, Kaspersky, Cisco, or others, making it a vendor-neutral program.

What is the Certified Information Security Manager ( CISM ) exam?
Passing the Certified Information Security Manager (CISM) exam indicates that the credentialed individual is an expert in the governance of information security, developing security programs and managing them, as well as managing incidents and risk. For someone to be considered “certified,” they must have passed the exam within the last five years, as well as work full-time in a related career, such as information security and IT administration. The exam tests individuals’ knowledge regarding the risks facing different systems, how to develop programs to assess and mitigate these risks, and how to ensure an organization’s information systems conform to internal and regulatory policies. The exam also assesses how a person can use tools to help an organization recover from a successful attack.

What are the different types of hackers?
The different types of hackers include white hat hackers who are ethical hackers and are authorized to hack systems, black hat hackers who are cybercriminals, and grey hat hackers, who fall in-between and may not damage your system but hack for personal gain. There are also red hat hackers who attack black hat hackers directly. Some call new hackers green hat hackers. These people aspire to be full-blown, respected hackers. State-sponsored hackers work for countries and hacktivists and use hacking to support or promote a philosophy. Sometimes a hacker can act as a whistleblower, hacking their own organization in order to expose hidden practices. There are also script kiddies and blue hat hackers. A script kiddie tries to impress their friends by launching scripts and download tools to take down websites and networks. When a script kiddie gets angry at…

FAQ regarding Penetration Testing on Udemy

What is penetration testing?
Penetration testing, or pen testing, is the process of attacking an enterprise’s network to find any vulnerabilities that could be present to be patched. Ethical hackers and security experts carry out these tests to find any weak spots in a system’s security before hackers with malicious intent find them and exploit them. Someone who has no previous knowledge of the system’s security usually performs these tests, making it easier to find vulnerabilities that the development team may have overlooked. You can perform penetration testing using manual or automated technologies to compromise servers, web applications, wireless networks, network devices, mobile devices, and other exposure points.

What are the different types of penetration testing?
There are many types of penetration testing. Internal penetration testing tests an enterprise’s internal network. This test can determine how much damage can be caused by an employee. An external penetration test targets a company’s externally facing technology like their website or their network. Companies use these tests to determine how an anonymous hacker can attack a system. In a covert penetration test, also known as a double-blind penetration test, few people in the company will know that a pen test is occurring, including any security professional. This type of test will test not only systems but a company’s response to an active attack. With a closed-box penetration test, a hacker may know nothing about the enterprise under attack other than its name. In an open-box test, the hacker will receive some information about a company’s security to aid them in the attack.

What are the different stages of penetration testing?
Penetration tests have five different stages. The first stage defines the goals and scope of the test and the testing methods that will be used. Security experts will also gather intelligence on the company’s system to better understand the target. The second stage of a pen test is scanning the target application or network to determine how they will respond to an attack. You can do this through a static analysis of application code and dynamic scans of running applications and networks. The third stage is the attack phase, when possible vulnerabilities discovered in the last stage are attacked with various hacking methods. In the fourth stage of a penetration test, the tester attempts to maintain access to the system to steal any sensitive data or damaging systems. The fifth and final stage of a pen test is the reporting phase, when testers compile the test results.

Since free tools and platforms are used, you don’t need to buy any tool or application.

You will have the hands-on practices to find out and exploit the most common vulnerabilities such as SQL injection, XSS (Cross Site Scripting) and CSRF (Cross Site Request Forgery).

Before starting to learn how to “ethically” hack a website, you’ll learn how to set up a lab environment and install the needed virtual machines such as Kali Linux and OWASP Broken Web Applications. This will allow you to practice and hack “safely” without affecting your main systems.

Then, you’ll learn the basic terms, standards, technologies and protocols of web applications: HTML, URL, HTTP etc.

When you’re ready to start hacking, you’re going to start with information gathering. In addition, you will learn how to use search engines to find out if there are known-vulnerabilities in the website. While discovering the website, you’ll analyse the configurations to understand if they cause any vulnerability.

Then, you’re going to learn the most important part of hacking web applications: how to manipulate input fields and the outputs produced by the application. You’ll see the most famous and dangerous vulnerabilities including SQL injection and Cross Site Scripting (XSS) in this section.

You will not only learn how to find out the vulnerabilities, but also learn how to exploit and hack those weaknesses. In addition, the methods to prevent hacking of these weaknesses will be taught.

After that, you’re going to learn how to discover authorisation, authentication and session management flaws. You’ll learn how to find usernames and passwords using brute force attacks, how to fix a session, how to escalate a privilege, how to discover and exploit Cross Site Request Forgery (CSRF) and more.

In this course, you will find the clean and pure information. When preparing the training, we especially avoided unnecessary talk and waiting; we have found these parts for you and gotten them out.

When you finish the course, you’ll understand
