Linux Skills

Linux is a free and open-source operating system based on the Linux Kernel. The source code of Linux can be modified and distributed to anyone commercially or non commercially under the GNU General Public License. The main reason why learn Linux for ethical hackers is its security. Linux is more secure than any other operating system. Although 100 per cent security is not guaranteed for Linux, it has some malware which makes it less vulnerable than any other operating system. Furthermore, it does not require any anti-virus software. Therefore, it is crucial to have Linux skills for hacking.

Programming Skills

Programming Skills are another most crucial skill to become an ethical hacker. Programming means “The act of writing code understood by a computational device to perform various instructions.” So, if you want to be an ethical hacker, you need to know the various programming languages used by hackers and the languages required for hacking. 

Which Are The Languages Used For Hacking?

Although there are many programming languages, all are not used for hacking purposes. Here is the list of programming languages used by ethical hackers. 

  • Python
  • SQL
  • C
  • JavaScript

The SQL injection is used to bypass weak web application login algorithms, delete data from the database, etc.

An Ethical Hacker needs to master SQL Skills for Hacking. They must: 

  • Learn how to perform a SQL injection against login
  • Learn how to include metadata in the SQL injection results
  • Understand the purpose of error-based SQL injection
  • Write the syntax to load a file into the web page using SQL injection
  • Demonstrate how to write to a file with SQL injection
  • Uncover tools that automate SQL injection attacks.

Hardware Knowledge   

An Ethical Hacker must have the basic computer hardware knowledge for ethical hacking. Computer hardware comprises the physical parts of a computer, like the central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard, etc.

In contrast, the software is the set of instructions that can be stored and run by hardware. Therefore, if someone wants to hack a machine controlled by a computer, he needs to know about the device or how it works. Then, he has to access the computer that controls the machine. Therefore, having basic Hardware Knowledge is the key to becoming an ethical hacker first. If one doesn’t know about hardware, how will they know how the motherboard works, how USBs transfer data, how CMOS or BIOS work together, etc.? So one must have basic hardware knowledge also to become an ethical hacker.

Knowledge in Reverse Engineering

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. 

Reverse engineering aims 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 make a device stable, thereby shielding it from spyware and hackers. Some developers also hack their systems, known as ethical hacking, to recognize vulnerabilities.
