Definition of Penetration Testing in Computer Science

📚 Quick Study Guide

• 🔍 Definition: Penetration testing, also known as pen testing, is a simulated cyberattack against your system to check for exploitable vulnerabilities.
• 🛡️ Purpose: Identify weaknesses in systems, applications, and network infrastructure *before* malicious actors can exploit them.
• 🛠️ Types:
  • ⚫ Black Box Testing: The tester has no prior knowledge of the system.
  • ⚪ White Box Testing: The tester has complete knowledge of the system.
  • Gray Gray Box Testing: The tester has partial knowledge of the system.
• ⚙️ Process:
  • 👣 Planning & Reconnaissance: Defining the scope and gathering information.
  • 🔎 Scanning: Identifying entry points and vulnerabilities.
  • 💥 Gaining Access: Exploiting vulnerabilities.
  • 🛰️ Maintaining Access: Seeing how long access can be maintained.
  • 📝 Analysis & Reporting: Documenting the findings and suggesting remediation.
• 💡 Tools: Examples include Metasploit, Nmap, Wireshark.
• 🔑 Key Benefit: Helps organizations improve their security posture by proactively identifying and addressing vulnerabilities.
