How to Learn Hacking from Scratch? 


These days, the newspaper is frequently dominated by stories about financial fraud, data breaches, internet incursions, and cyber warfare. Keeping their networks and resources safe from malicious users has always been a difficult task for cybersecurity specialists. The fact that the internet is so accessible worldwide motivates a lot of hackers to engage in cybercrime. Hackers have impacted everything, from the political to the economic, since this has become increasingly prevalent. 

But not all hacking activities are classified as crimes. If done with consent, hacking is permissible. A system or computer network might have vulnerabilities that can be found by penetration testing, which is a legitimate and legal method. Organizations frequently hire computer specialists to get into their systems and find weak links and vulnerabilities so that they may fix them. These days, there is a huge demand for skilled ethical hackers and other cybersecurity professionals. 

If you want to learn the skill of ethical hacking, you get yourself enrolled in an Ethical Hacker training course. However, let’s begin by learning more about hacking. 

What is Hacking?  

Hacking is the process of locating and then taking advantage of flaws in a computer system or network, generally in order to obtain unauthorized access to personal or business data. Even though hacking may not always have bad intentions, in modern times the majority of references to the subject refer to hackers and describe their illegal activity as being carried out by cybercriminals for a variety of reasons, including monetary gain,, information gathering (spying), social protest or even just for the fun. The word “hacking” refers to the inappropriate use of technology to damage or disrupt systems, steal user information, retrieve data and documents, or disrupt data-related activity. This includes using computers, cell phones, and tablets. 

Why Should You Learn Ethical Hacking?  

Testing a system’s network for vulnerabilities against any malware and viruses, thefts, or assaults that might result in financial loss or other damages to the system is known as ethical hacking. Ethical hacking uses tactics that are likewise utilized by illegal hackers in order to penetrate systems properly. The main difference is that an ethical hacker gets permission from authorized personnel to try to break into the system in order to improve defenses against serious attacks. 

You may play a crucial part in protecting the systems and data from threats and assaults by learning ethical hacking. When you know how to  hack ethically, you can: 

  • Contribute to the establishment of a cutting-edge network that is resistant to security breaches. 
  • Conduct research and analysis on the target systems to find any security or system flaws from the hacker’s perspective and provide a fix 
  • To better prepare for upcoming harmful hacker assaults, conduct a controlled evaluation of company networks and systems by simulating a real-time attack. 
  • Contribute to government efforts to protect a country’s infrastructure from radicals. 
  • By establishing best-in-class security policies, you can preserve consumer faith and trust by protecting their data and information. 

Is Ethical Hacking Hard to Learn?  

Even though ethical hacking is not tough to learn, it is a very technical profession. Before starting to get paid to gain access to people’s computers for a job, it would be beneficial for you to have a broad knowledge base. Among the most crucial things to understand and remember is that hacking—whether it’s done for good or bad—is a constantly developing craft, and you need to be informed of any new developments that arise. Understand how to stay anonymous. Being an ethical hacker requires you to do this. 

Skills Required to Learn Ethical Hacking  

Ethical hacking is the process of evaluating potential hazards and looking for flaws in a computer or network. A computer, online application, or network fault area or security gap is located and reported to the firm by an ethical hacker. So let’s evaluate what skills are necessary to become an ethical hacker: 

Basic IT & Computer Skills – You need to have good computer skills in order to be a successful ethical hacker. In order to safeguard computer systems and networks, ethical hacking involves first locating vulnerabilities in the systems. Although it can seem uncomplicated, ethical hacking is a difficult procedure that needs a thorough knowledge of both computer hardware and software. MS Office, Email, Database Management, Spreadsheets, Web, Social Media,  etc. are some of the most crucial computer abilities. 

Programming – Programming skills are another crucial trait to have to become an ethical hacker. Writing code that a computing device can understand and use to carry out various commands is referred to as programming. Without the knowledge of the program, it would be hard to comprehend how systems operate and how to identify their flaws. Java,  Python, and PHP are the three programming languages that ethical hackers utilize the most. The key is to have a thorough grasp of how code functions and how it may be applied to either generate or address issues. 

Computer Networking – The capability to create networks efficiently is considered the most crucial skill among Ethical Hackers. Ethical hackers can readily study and access various interconnected machines in the concerned network & point out the probable security concerns it might present in the future, while giving solutions to mitigate those security threats, by understanding different networks, including Subnetting, DHCP, and many more. 

Web Applications & Websites – The capacity to identify and take advantage of online application vulnerabilities is a crucial trait for ethical hackers. Code review, network analysis, and black box testing are just a few of the methods that hackers might employ to uncover these vulnerabilities. Once a flaw has been identified, the hacker can use it to obtain private information or take over the program. Ethical hackers need to have a thorough grasp of how online applications function in order to identify and take advantage of their flaws. 

Linux Operating System (OS) – As anybody working in the IT industry is aware, Linux is a strong operating system that offers users a variety of tools and functions. Linux skills are vital for ethical hackers since they provide you access to a system’s internals and let you see possible security holes. While there are numerous methods to learn Linux, working with a number of various distributions gives you the most practical experience and is the most efficient way to do it. Linux is both less prone to vulnerability and more secure than any other operating system. Therefore, no anti-virus software is needed. 

Cryptography – Cryptography, sometimes known as adversarial cryptography, is the research and use of techniques for private communication while third-party candidates, also known as adversaries, are present. Cryptography is a fundamental ethical hacker ability that is necessary for ethical hacking. An ethical hacker must ensure that information about conversations between various employees does not leak. Cryptography is a tool used by ethical hackers to prevent unwanted access to data. In order to access sensitive information without setting off alarms, they also utilize it to build backdoors into systems. 

Behavioral Psychology & Social Engineering – Combining technical and social abilities is necessary for ethical hacking. A strong understanding of social engineering is also necessary for ethical hackers. Being able to learn details about potential targets through observation, study, and discussion is a part of this. This data is used by ethical hackers to target weaknesses in security measures.
