Whenever we hear the word “hacking”, we think of it as a negative act of stealing passwords and data from other websites. While this is not true, hacking can be used for beneficial purposes. One such act of hacking for good is called Ethical Hacking.
What is Ethical Hacking?
Ethical hacking is a legal hacking technique in which hackers use their skills for the defense or security purpose of their working area or agency.
Companies that work online are at a greater risk of hacking, all such companies perform ethical hacking techniques like penetration testing to ensure the safety and security of their company’s websites. In order to determine the security and vulnerability of a company’s website, ethical hackers have to compromise their computer systems.
Ethical Hacking is a key skill when considering several job roles related to protecting an organization's online properties. The professionals working on these activities manage the machines, networks and servers of the particular company. An Ethical Hacking course have helped professionals and individuals to scale up their career ladder and find better pay.
The question arises how a person can become an ethical hacker, so let’s discuss some of the points to become ethical hackers.
Important Skills Needed for Ethical Hacking
Some of the most important ethical hacking skills one must-have to become an ethical hacker includes:
To become an ethical hacker the most important skill that is necessary is networking skills. The computer network is the connection of multiple devices, these multiple devices are mostly the host that sends data and receives data.
To be a successful hacker you should know about network models, internet protocols and IP address. You should also be familiar with Routers, Servers, Clients, and Transmission Media, access points, Shared Data and Network Interface Card etc.
Computer skills are abilities that allow one to use computers and computer technology. Basic computer skills include processing data, computer files management, and creating presentations. Advanced skills may include managing databases, programming, and doing calculations in spreadsheets. Some of the most essential computer skills are MS Office including all its programs, Spreadsheets, Email, Database Management, Social Media, Web, etc. An ethical hacker needs to be a computer systems expert.
It is an open-source Unix culture, like the Linux Kernel-based operating systems. It is a free and open-source operating system, and under the GNU General Public License, the source code can be updated and distributed to anyone commercially or non-commercially.
The key justification for learning about Linux as an ethical hacker is that Linux is more stable in terms of security than any other operating system. This does not mean that Linux is 100 percent stable, but less vulnerable than any other operating system, since it has some malware. Therefore, it doesn’t need anti-virus software.
Programming Skills are another most critical ability to become an ethical hacker. So, what does the term programming really mean in the machine world? It means, "The act of writing code understood to perform different instructions by a computational device." So, one will be writing a lot of code to get better at programming! Before you write code, you have to choose the right programming language for your programming. Here is the list of programming languages.
SQL is a Cross-platform programming language used to communicate with databases. As an ethical hacker, having SQL skills will help you to hack a website for good. The SQL injection can be used to by-pass web application login algorithms that are weak, and even delete data from the database.
When you start learning the core of hacking, Python language is great. With a giant standard library and a packaging system that puts prebuilt tools and frameworks at your fingertips, it is often very easy to hack something into existence.

Having a good idea of hardware or how to handle it is advantageous if you wish to be an ethical hacker. The physical components of a computer, such as the central processing unit (CPU), display, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard, etc., consists a computer’s hardware. The program, on the other hand, is a series of instructions that can be stored and controlled by hardware. Suppose, for instance, one tries to hack a machine that is operated by a computer. He wants to inquire about the computer or how it operates first. Finally, he has to obtain access to the computer that controls the machine. Now, the computer would have a very good protection framework for software; but hackers don't care about hardware security, so if someone can access it, they can play with the hardware.
Knowledge in Reverse Engineering
Knowledge in Reverse Engineering is another added skill an Ethical Hacker should possess. Reverse Engineering is a method of retrieving a product's architecture, requirements and features from an analysis of its code. It creates a database of programs and extracts knowledge from it. The aim of reverse engineering is to speed up the maintenance work by enhancing a system's understandability and generating the requisite documentation for a legacy system.
Reverse engineering is commonly used in software security to ensure that any significant security bugs or weaknesses are missing from the framework. It helps to make a device stable, thereby shielding it from spyware and hackers. Some developers also go as far as hacking their system, a system known as ethical hacking, to recognize vulnerabilities.
Cryptography knowledge is another area an ethical hacker should be skilled in. Cryptography is the study and use of techniques in the presence of third parties called adversaries for secure communication. It deals with the creation and analysis of protocols that prevent the exchange of information between two entities by malicious third parties. Thus pursuing the various aspects of information security.
To make it nonsensical to hackers, cryptography deals with translating a standard text/message known as plain text to a non-readable type known as ciphertext throughout the transmission. An ethical hacker must ensure that there is no leakage of contact between various entities within the organization.
The crux of the development and management of all databases is DBMS. Accessing a database where all the data is stored will put the business at considerable risk, so it is necessary to ensure that this program is hack-proof. In order to help the company create a powerful DBMS, an ethical hacker must have a clear understanding of this, along with various database engines and data schemes.
Problem-solving skills allow one to assess and find an appropriate solution to the root of a problem. An Ethical Hacker should be a strategic thinker and creative problem solver apart from the technological skills pointed out above. You may have to learn new approaches to ensure that any violations of security are carefully reviewed. This needs loads of tests and an ingenious penchant for discovering new forms of solving the problem.
The above skills allow you to achieve your desired goals within the available time and resources. As an Ethical Hacker, you will need to develop these skills to help you get the job done. Using these skills you could learn how to program, use the internet, be good at solving problems, and take advantage of the existing security tools. Today, every high-profile organization brings on ethical hackers to test the security of their networks. More and more companies have begun to invest in strengthening the safety of their software and hardware systems. Certified Ethical Hacker Course will help you to protect any network and systems from data breaches and threats.
