What Is Ethical Hacking?

Ethical hacking is the authorized practice of testing computer systems, networks, or applications to find security weaknesses. Ethical hackers use the same techniques as cybercriminals—but with permission and for defensive purposes.

Ethical hackers are also known as:

• White Hat Hackers
• Penetration Testers
• Cybersecurity Analysts

Their goal is to protect data, systems, and users, not to cause harm.

Is Ethical Hacking Legal?

Yes, ethical hacking is completely legal when performed with proper authorization.

Legal Ethical Hacking Includes:

• Written permission from the system owner
• Clearly defined scope of testing
• Reporting vulnerabilities responsibly
• No data misuse or damage

Illegal Hacking Includes:

• Accessing systems without permission
• Stealing personal or financial data
• Disrupting services or networks

⚠️ Without permission, hacking is a crime—even if your intention is good.

How Ethical Hacking Works

Ethical hacking follows a structured process:

1. Reconnaissance (Information Gathering)

Collecting publicly available information about the target system.

2. Scanning & Enumeration

Identifying open ports, services, and potential entry points.

3. Vulnerability Assessment

Finding security weaknesses such as outdated software or weak passwords.

4. Exploitation

Testing whether vulnerabilities can be exploited safely.

5. Reporting

Preparing a detailed report with findings and security recommendations.

Types of Ethical Hacking

Ethical hacking covers various areas, including:

Network Hacking

Testing firewalls, routers, and network configurations.

Web Application Hacking

Identifying issues like SQL injection, XSS, and CSRF.

System Hacking

Checking operating systems for misconfigurations.

Wireless Hacking

Testing Wi-Fi security and encryption standards.

Social Engineering (Authorized)

Evaluating human vulnerabilities through controlled simulations.
