Lab 12 - Telnet and SSH ( I Captured My Own Password in Wireshark — Here's What Telnet Taught Me About Network Security )

Short summary

Hands-on networking lab that demonstrates why SSH is essential and Telnet is dangerous. The author sets up a 4-router GNS3 network, configures both protocols, then captures traffic in Wireshark to show Telnet's plain-text passwords visible to any network attacker and SSH's encrypted protection. Essential learning for understanding network security fundamentals.

• •Practical lab comparing Telnet (unencrypted) vs SSH (encrypted) protocols
• •Uses GNS3 simulation and Wireshark packet capture to demonstrate security differences
• •Hands-on learning of router configuration and network security basics
