Top 10 Skill Requirements for an Ethical Hacker

1. Computer Networking Skills

The ability to network is one of the most crucial requirements for becoming an ethical hacker. In order to send and receive data or media, a computer network consists of a number of devices, commonly referred to as hosts, connected by a number of paths.

Gaining knowledge of networks such as DHCP, supernetting, subnetting, and others will enable ethical hackers to investigate the different connected computers in a network, the possible security risks that may arise, and how to mitigate those risks. Computer network tutorials are a good resource for learning computer networking.  

2. Computer Skills

The ability and knowledge necessary to operate computers and related technology are known as computer skills. Generally speaking, data processing, file management, and presentation creation are considered fundamental computer skills. Database management, spreadsheet computation, and programming are examples of advanced computer skills.

Microsoft Office, spreadsheets, email, database administration, social media, the web, enterprise systems, etc. are some of the most important computer skills. An ethical hacker must possess extensive knowledge of computer systems.  

3. Linux Skills

Based on the Linux kernel, Linux is a community of open-source operating systems. The operating system is free and open-source, and anyone can alter and distribute its source code under the GNU General Public License, whether for profit or not. The primary reason an ethical hacker should learn Linux is that, in terms of security, it is more secure than other operating systems.

This does not imply that Linux is completely safe; it does have some malware, but it is less susceptible than other operating systems. Antivirus software is therefore not necessary.  

4. Programming Skills

The ability to program is another essential skill for becoming an ethical hacker. What, then, does the term "programming" mean in the context of computers? "The act of writing code that a computational device understands to perform various instructions" is what it means. Writing a lot of code will therefore be necessary to improve one's programming skills.

One must select the most appropriate programming language before writing any code. The programming languages that ethical hackers use are listed here, along with resources for learning them.

• Python: Python Programming Language
• SQL: SQL Tutorial
• C: C Programming Language
• JavaScript: JavaScript Tutorials
• PHP: PHP Tutorials
• C++: C++ Programming Language
• Java: Java Programming Language
• Ruby: Ruby Programming Language
• Perl: Perl Programming Language 

5. Basic Hardware Knowledge

Computer hardware includes the actual components of a computer, such as the motherboard, graphics card, sound card, speakers, central processing unit (CPU), monitor, mouse, keyboard, and computer data storage. Software, on the other hand, is the collection of instructions that hardware can store and execute. Let us take an example where someone wants to hack a computer-controlled machine. He must first understand the machine's operation.

The final step is for him to gain access to the computer that runs the machine. The machine will now be equipped with an excellent software security system. However, if he has access to the hardware, he can play with it because hackers do not care about hardware security. If someone is not familiar with hardware, how will they understand how the motherboard functions, how USBs transfer data, how CMOS and BIOS interact, etc.? Therefore, in order to become an ethical hacker, one must also possess a basic understanding of hardware. 

6. Reverse Engineering

The process of recovering a product's design, requirements, and functions from an analysis of its code is known as reverse engineering. It builds a program database and generates information from this. Reverse engineering aims to create the required documentation for a legacy system and speed up maintenance by making a system easier to understand.

To make sure the system is free of significant security vulnerabilities or flaws, reverse engineering is a common technique in software security. It makes a system more resilient, which keeps hackers and spyware away from it. Some developers even go so far as to hack their system in order to find weaknesses; this is known as ethical hacking. 

7. Cryptography Skills

The study and use of methods for trustworthy communication in the presence of adversaries—third parties—is known as cryptography. In order to adhere to the different facets of information security, it deals with creating and evaluating protocols that stop malevolent third parties from obtaining data that has been exchanged between two entities.

The goal of cryptography is to render ordinary text or messages—known as plain text—unintelligible to hackers by transforming them during transmission into ciphertext.

It is imperative for an ethical hacker to ensure that communication between various individuals within the organization does not leak. See Network Security and Cryptography to learn the fundamentals of cryptography. 

8. Database Skills

All databases are created and managed using DBMS. It is crucial to make sure that this software is impenetrable to hackers because accessing a database that contains all of the company's data can be extremely dangerous.

An ethical hacker needs to be well-versed in various database engines and data schemas in order to assist the company in developing a robust DBMS. Consult the Database Management System (DBMS) to learn more about it. 

9. Problem-solving Skills

One can identify the cause of an issue and come up with a workable solution with the aid of problem-solving abilities. An ethical hacker needs to be able to think critically and solve problems creatively in addition to having the technical abilities mentioned above.

They must want to learn new things and make sure that every security breach is investigated in detail. This necessitates extensive testing and a creative knack for coming up with novel approaches to problem-solving.

10. Steganography Skills

The ability to embed secret information into seemingly normal files, such as images, audio, or videos, is known as "steganography skills" in cybersecurity. This technique allows for covert communication by concealing sensitive information within a carrier file without drawing attention to itself, making it a useful tool for both information protection and malicious activity detection; in other words, it is the art of hiding messages "in plain sight."

Conclusion:

Ethical hackers play a vital role in enhancing organizational security by identifying vulnerabilities and providing recommendations for remediation, thereby safeguarding digital assets against potential cyber threats. Their expertise, which combines technical skills, practical experience, and ethical conduct, is increasingly essential in today's landscape of sophisticated cyberattacks.
