Therefore, it has become very important to learn Ethical Hacking

This Beginner’s Guide We will tell you the importance of ethical hacking, its benefits, what is ethical hacking, and how you can make a career in it

What is Ethical Hacking?

Ethical hacking: – It means finding vulnerabilities by manipulating any systems, software, or networks in a legal manner, so that no criminal use can be exploited and misused

An Ethical hacker called a white hat hacker always checks security by following all permissions and rules of law, and in front of him, a black hat hacker who is criminals is also like ethical hackers who clean up cybersecurity. Ethical hackers work to strengthen cybersecurity and “clean up” systems — that is, to expose vulnerabilities and make them more secure from malicious hackers.

Example: When a company hires a White Hat hacker to test its website, Ethical Hacker will use SQL injection, Phishing or Brute-Force attacks to identify the vulnerabilities. But they never steal their data and never misuse it.

Types of Hackers

Before you learn about ethical hacking, you should know how many types of hackers there are.

1. Black Hat Hackers – The exact opposite of white hat hackers are black hat hackers. They hack the system without permission and steal their personal details and data. As a result, companies and organizations may sometimes face problems like financial losses.
2. White Hat Hackers – White hat hackers always work in a legal way. These people hack the system by taking the permission of the company and organization and test them and find out their weaknesses. These people use their skills to make the company’s security strong.
3. Grey Hat Hackers – Gray hat hackers are a mix of both black hat and white hat hackers. This or type hackers are good, but their way of working is illegal. These hackers find vulnerability in the system without permission. They would have done no harm to anyone.

Types of Ethical Hacking

• Network Penetration Testing– Testing Reuters, firewalls, and LAN/WAN using tools like Nmap and Metasploit to identify open ports.
• Web Application Testing– testing websites, web applications using tools like burp suite, OWASP etc
• Mobile App Security Testing – This involves testing Android and iOS applications.
• Wireless (Wi-Fi) Network Testing –  This involves testing protocols such as WPA/WPA2/WPA3 and wireless networks such as Wi-Fi.
• Social Engineering– Getting people to reveal information by deception.
• Physical Penetration Testing – Their job involves tasks such as bypassing locks and gaining access to system controls.
• Cloud Security Testing – testing cloud setups (like AWS, Azure and GCP), misconfigurations etc.

Why Ethical Hacking is Important?

In today’s modern world full of technology, cyber-crime takes place every day. As a result, the company, the bank, the government, the people and sometimes the whole country suffer a loss of lakhs of crores.

In 2025, cybercrime has cost 10.5 trillion US dollars in the whole world, and it is said that if cybercrime increases even more, then this number can reach $ 16 trillion by 2029.

6 Common Techniques Used in Ethical Hacking

In ethical hacking, hackers test system security by using different types of methods and techniques. I will tell you about 6 common techniques used by hackers.

1. Foot printing & Reconnaissance – This involves targeting the system, exploiting vulnerabilities within it, and gathering information from the system.
2. Scanning Networks – In this method, tools like Nmap and Burp Suite are used to check open and closed ports, allowing us to collect information such as the target system’s IP address and user accounts.
3. Gaining Access – The system is exploited using tools like phishing and Metasploit so that we can gain access to the system.
4. Privilege Escalation– Privilege escalation means gaining higher-level access to a system, allowing us to move from a normal user account to an account with administrative control.
5. Clear Tracks: This method is used to erase all evidence from a hacked system.
6. Reporting – This is the final phase, in which the hacker prepares a report of all the information they have gathered, and this report must be given to the system owner or company.
