INTRODUCTION TO ETHICAL CYBER SECURITY 11 | Ethiopia | በአማርኛ

Introduction

This tutorial provides an introduction to ethical cyber security, specifically focusing on network hacking. It is part of a series aimed at educating individuals about ethical hacking practices. Understanding network vulnerabilities and hacking techniques is crucial for professionals in the field of cybersecurity, as it helps protect networks from malicious attacks.

Step 1: Understanding Network Hacking Basics

• Definition: Network hacking refers to exploiting weaknesses in networks to gain unauthorized access.
• Purpose: Ethical hackers aim to identify vulnerabilities to improve network security.
• Types of Network Attacks:
  • Active Attacks: Involves altering the data (e.g., man-in-the-middle attacks).
  • Passive Attacks: Involves eavesdropping on network communications without altering data.

Step 2: Setting Up Your Environment

• Tools Required:
  • Install a virtual machine (VM) software (e.g., VirtualBox or VMware).
  • Use a penetration testing distribution (e.g., Kali Linux).
• Configuration:
  • Set up your VM with Kali Linux.
  • Ensure your VM network settings allow for both NAT and bridged connections to simulate different environments.

Step 3: Information Gathering Techniques

• Active Information Gathering:
  • Use tools like Nmap to scan networks and identify open ports.
  • Command example:

    nmap -sP 192.168.1.0/24
    

• Passive Information Gathering:
  • Monitor network traffic using tools like Wireshark.
  • Analyze packet data to identify potential vulnerabilities.

Step 4: Identifying Vulnerabilities

• Scanning Tools:
  • Use vulnerability scanners (e.g., Nessus, OpenVAS) to identify weaknesses.
• Common Vulnerabilities:
  • Unpatched software
  • Weak passwords
  • Open ports

Step 5: Exploiting Vulnerabilities

• Ethical Considerations:
  • Always have permission before attempting to exploit any vulnerabilities.
  • Follow legal guidelines and ethical practices.
• Exploitation Techniques:
  • Use Metasploit framework for testing vulnerabilities.
  • Command example:

    msfconsole
    

Conclusion

In this tutorial, we explored the basics of network hacking within the context of ethical cyber security. Key takeaways include understanding the types of network attacks, setting up a safe environment for testing, gathering information, identifying vulnerabilities, and ethical considerations when exploiting those vulnerabilities.
