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
