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.
