Fundamentals of Ethical Hacking

Fundamentals of Ethical Hacking 🛡️

Ethical hacking, also known as penetration testing or white-hat hacking, involves legally breaking into systems to identify vulnerabilities before malicious hackers exploit them. Ethical hackers use their skills to strengthen cybersecurity and protect sensitive information.

📌 1. What is Ethical Hacking?

Ethical hacking is the authorized practice of testing a system, network, or application for security weaknesses. Unlike black-hat hackers, ethical hackers follow legal and professional guidelines.

📌 2. Key Concepts in Ethical Hacking

🔹 Reconnaissance (Information Gathering) – Collecting data about a target system before launching an attack.
🔹 Scanning & Enumeration – Identifying open ports, services, and vulnerabilities.
🔹 Gaining Access – Exploiting vulnerabilities to break into systems.
🔹 Maintaining Access – Keeping access for further analysis (done ethically for security testing).
🔹 Covering Tracks – Ethical hackers must not erase logs but learn how attackers might do so.

📌 3. Types of Hackers

👨‍💻 White Hat Hackers – Ethical hackers who work to improve security.
🕶️ Black Hat Hackers – Malicious hackers who exploit systems for personal gain.
⚪ Grey Hat Hackers – Hackers who identify flaws without permission but report them.

📌 4. Important Ethical Hacking Tools

🔹 Nmap – Network scanning tool
🔹 Metasploit – Exploitation framework
🔹 Wireshark – Network traffic analysis
🔹 Burp Suite – Web vulnerability scanner
🔹 Kali Linux – A security-focused OS with built-in hacking tools

📌 6. Legal & Ethical Considerations

🔹 Always have written permission before testing systems.
🔹 Follow laws and regulations (e.g., IT Act, GDPR, Cybersecurity Laws).
🔹 Do not exploit data for personal gain.
