🛡️ What is Ethical Hacking?

📘 Definition

Ethical Hacking is the process of legally breaking into computers, systems, or networks to test their security and find vulnerabilities before malicious hackers can exploit them.

An Ethical Hacker is also known as a White Hat Hacker.

🎯 Purpose of Ethical Hacking

  • Identify security weaknesses

  • Prevent cyber attacks

  • Protect sensitive data

  • Improve system security

  • Ensure compliance with security standards

👨‍💻 Who is an Ethical Hacker?

An Ethical Hacker is a cybersecurity professional who:

  • Has permission to test systems

  • Follows legal guidelines

  • Reports vulnerabilities responsibly

  • Helps organizations strengthen security

They work for companies, government agencies, banks, and IT firms.

🎩 Types of Hackers

1️⃣ White Hat Hackers

Ethical hackers who work legally to improve security.

2️⃣ Black Hat Hackers

Malicious hackers who steal data or damage systems.

3️⃣ Grey Hat Hackers

Hack without permission but may not have harmful intent.

🔎 Phases of Ethical Hacking

Ethical hacking follows a structured process:

1️⃣ Reconnaissance (Information Gathering)

Collecting information about the target system.

2️⃣ Scanning

Identifying open ports, vulnerabilities, and weaknesses.

3️⃣ Gaining Access

Attempting to exploit vulnerabilities.

4️⃣ Maintaining Access

Testing whether continued access is possible.

5️⃣ Clearing Tracks

Checking how attackers hide their activities.

🔐 Types of Ethical Hacking

🌐 Network Hacking

Testing network security.

🖥️ System Hacking

Finding vulnerabilities in operating systems.

🌍 Web Application Hacking

Testing website security.

📶 Wireless Network Hacking

Checking Wi-Fi security.

📱 Mobile Hacking

Testing mobile app vulnerabilities.

👥 Social Engineering

Testing human security awareness.

🛠️ Common Ethical Hacking Tools

  • Nmap (Network scanning)

  • Wireshark (Packet analysis)

  • Metasploit (Penetration testing framework)

  • Burp Suite (Web testing)

  • John the Ripper (Password testing)

  • Kali Linux (Security testing OS)

📜 Legal Aspects

Ethical hacking is legal only when:

  • Written permission is obtained

  • Work is within agreed scope

  • Findings are reported responsibly

Without permission, hacking is illegal.

🏆 Benefits of Ethical Hacking

  • Prevents data breaches

  • Protects business reputation

  • Saves financial losses

  • Ensures regulatory compliance

  • Builds customer trust

⚠ Risks

  • Legal issues if done without permission

  • Misuse of tools

  • Exposure of sensitive data if not handled properly

📚 Skills Required

  • Networking knowledge

  • Operating systems (Windows, Linux)

  • Programming (C, Python, Java)

  • Web technologies (HTML, PHP, SQL)

  • Cybersecurity concepts

  • Problem-solving skills

🎓 Certifications in Ethical Hacking

  • CEH (Certified Ethical Hacker)

  • OSCP (Offensive Security Certified Professional)

  • CompTIA Security+

  • CISSP

🔥 Real-World Applications

  • Banking systems security

  • Government cybersecurity

  • Corporate IT security

  • E-commerce platforms

  • Cloud security testing

📌 Short Exam Definition

Ethical Hacking is the legal practice of testing computer systems and networks for security vulnerabilities using hacking techniques with proper authorization.

Computers are electronic devices that are designed to process, store, and retrieve data. They are used for a wide variety of purposes, from personal computing to complex scientific simulations and industrial automation. A computer consists of various hardware components, including a central processing unit (CPU), memory, storage devices, input/output (I/O) devices such as keyboards, mice, and displays, and various other peripherals. Computers communicate with each other over networks, which are interconnected groups of computers that share resources and information. The internet is a global network that connects millions of computers around the world and enables communication and information sharing on an unprecedented scale. The field of computer science is concerned with the study of computers and computational systems, including their design, development, and application. It encompasses many subfields, including artificial intelligence, computer graphics, databases, programming lang...

 There are five generations of computer:  First generation– 1946 - 1958  Second generation– 1959 - 1964  Third generation– 1965 - 1970  Fourth generation– 1971 - today  Fifth generation– Today to future The First Generation   The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.  They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. The Second Generation   Transistors replaced vacuum tubes and ushered in the second generation of computers.  One transistor replaced the equivalent of 40 vacuum tubes.    Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable.  Still generated a great deal of heat that can damage the computer. The Third Generation  The development of the integrated circuit was ...
