Network security lab focused on IP address discovery, port scanning, and hash function performance comparison under Linux.

Network analysis and security testing on Linux

Overview

This lab simulated network attacks and security testing to evaluate the robustness of a local network.
Tools like nmap, hashcat, and john were used to perform dictionary attacks and compare the performance of different hash algorithms (MD5, SHA1, SHA256).

Key Learnings

  • Network discovery and scanning with Nmap
  • Dictionary attacks and password hash analysis
  • SSH connection security best practices
