Honeypot System for Attacks on SSH Protocol

Honeypots are effective network security systems built to study the tactics of attackers and their intents. In this paper, we deployed Kippo honeypot to analyze Secure Shell attacks. Both the dictionary attack and intrusion activities of attackers have been discussed. We collected usernames and passwords that are attempted by dictionary attack targeting Secure Shell service. We have traced the frequently attacking machines based on their IP addresses. We have also recorded the commands they executed after successful logins to the Secure Shell honeypot server. We logged vast amount of connection requests destined to number of ports originated from different locations of the world. From our honeypot system, we have collected attack data that enables us to learn common Secure Shell based attacks.
