INTRODUCTION TO ETHICAL CYBER SECURITY 9 | Ethiopia | በአማርኛ

Introduction

This tutorial introduces the key concepts of ethical cybersecurity, specifically focusing on network hacking. It is part of a series that aims to equip you with the foundational knowledge necessary to understand network vulnerabilities and ethical hacking practices. Whether you're a beginner or looking to sharpen your skills, this guide will help you grasp essential topics in ethical cybersecurity.

Step 1: Understanding Ethical Hacking

• Definition: Ethical hacking involves legally breaking into computers and devices to test an organization’s defenses.
• Purpose: To identify vulnerabilities before malicious hackers can exploit them.
• Key Principles:
  • Obtain permission before testing.
  • Follow legal and ethical guidelines.
  • Report vulnerabilities responsibly.

Step 2: Basics of Network Security

• Network Security Fundamentals:

  • Protecting the integrity, confidentiality, and availability of data.
  • Use firewalls, intrusion detection systems, and encryption.

• Common Threats:

  • Malware: Software designed to disrupt or gain unauthorized access.
  • Phishing: Deceptive attempts to obtain sensitive information.

Step 3: Information Gathering

• Purpose: Collect information about your target to identify potential vulnerabilities.
• Techniques:
  • Passive Information Gathering: Collect data without interacting with the target.
    • Use search engines and social media.
    • Gather DNS information.
  • Active Information Gathering: Engage with the target to collect data.
    • Use tools like Nmap for network scanning.
    • Conduct port scans to identify open ports.

Step 4: Using Network Hacking Tools

• Popular Tools:

  • Nmap: For network discovery and security auditing.
    • Basic command to scan a network:

      nmap -sP 192.168.1.0/24
      

  • Wireshark: For network protocol analysis.
  • Metasploit: For developing and executing exploit code.

• Practical Tips:

  • Always test in a controlled environment.
  • Familiarize yourself with the tool's documentation.

Step 5: Analyzing Network Vulnerabilities

• Vulnerability Assessment:

  • Regularly evaluate network security measures.
  • Identify weaknesses through penetration testing.

• Reporting:

  • Document findings clearly and provide actionable recommendations.
  • Share reports with stakeholders to improve security measures.
