• Introduction

• Honeypot Technology

• KFSensor

• Honeyd

• Features

• Tests

• Conclusion

Introduction

• Good Defence is Good Offence

• Network security – Firewall, IDS, antivirus.

• Traditional approach – defensive

• Today – offensive approach

• Honeypot solutions

Honeypot Technology• “A honeypot is security resource whose value lies in

being probed, attacked, or compromised.” - Lance Spitzner

• we want attackers to probe and exploit the virtual system running emulated services.

• System no production value, no traffic, most connection probe, attack or compromised.

• Complements the traditional security tools.

TYPES of ATTACKERS

1) Script Kiddies- Amateurs, don’t care about the host- Educate the inadequacy of the security policy

1) Blackhat- Focus on high value system, more

experienced- More dangerous and operate silently

Types of HoneypotInteraction: level of activity Honeypot allows with attacker

• Low InteractionEmulated services, easy to deploy and maintain, less risk.

Designed to capture only known attack

• High InteractionSetup real services and provides interaction with OS

More information, no assumption made give full open environments.

Can use the real honeypot to attack others.

Symantec Decoy Server, Honeynet

KFSensor

• Commercial low interaction honeypot solution

• Windows OS

• Preconfigured services: ssh, http, ftp etc

• Easy configuration and flexible

• Components of KFSensor

• Scenarios, Sim Server – standard and banner

Honeyd

• Low interaction, open source

• Developed by Niels Provos of U of M

• Features: service emulation and IP stack of OS

• Product Detail• Software: honeyd

• Version: honeyd 0.8

• License: open source

• Download site: http://honeyd.org

• OS: Windows, Linux, Unix – Solaris

Installation

• ARPD, Libraries Dependencies

• Libevent-0.8a.tar.gz, libpcap0.8.3.tar.gz

• Honeyd package

Installation process:# tar -zvxf libevent-0.8a.tar.gz

Compile the libevent:

# cd libevent-0.8a (Note: pwd is /honeyd_packages/ libevent-0.8a)

#. /configure

# make

# make install

Major Differences between the two software

• IP address assignment

• Listening port

• OS emulation

• Open source advantage

• Financial value

How it works

1. Configuration File

2. Nmap.print & Xprobe2

3. Script for running the services

Test Environment

• Inside the router

1) University network

2) Home network: putting the honeypot system inside the router [192.168.0.102]

Various test performed:

Testing Honeyd

IP of honeypot: 192.168.1.122

IP of host running the honeypot: 192.168.1.121

1) Running ARPD

#arpd 192.168.0.0\24

2) Running Honeyd

#honeyd –d –f config.sample –p nmap.print –x xprobe2 –l \”Log File” –I 2

Test 1: FTP (KFSensor)

Conclusion

• Both are low interaction

• Honey with better feature like IP simulation and OS IP stack simulation

• KFSensor better GUI easy configuration

Can not replace the existing system. Work better along with it.
