- 2. Introduction A honeypot is a trap set to detect, deflect, or in some manner counteract attempts at unauthorized use of information systems They are the highly flexible security tool with different applications for security. They don't fix a single problem. Instead they have multiple uses, such as prevention, detection, or information gathering A honeypot is an information system resource whose value lies in unauthorized or illicit use of that resource
- 3. What is a Honey Pot? • A Honey Pot is an intrusion detection technique used to study hackers movements
- 4. What is a Honey Pot?(cont.) • Virtual machine that sits on a network or a client • Goals Should look as real as possible! Should be monitored to see if its being used to launch a massive attack on other systems Should include files that are of interest to the hacker
- 5. Classification By level of interaction • High • Low By Implementation • Virtual • Physical By purpose • Production • Research
- 6. Interaction Low interaction Honeypots • They have limited interaction, they normally work by emulating services and operating systems • They simulate only services that cannot be exploited to get complete access to the honeypot • Attacker activity is limited to the level of emulation by the honeypot • Examples of low-interaction honeypots include Specter, Honeyd, and KFsensor
- 7. Interaction High interaction Honeypots • They are usually complex solutions as they involve real operating systems and applications • Nothing is emulated, the attackers are given the real thing • A high-interaction honeypot can be compromised completely, allowing an adversary to gain full access to the system and use it to launch further network attacks • Examples of high-interaction honeypots include Symantec Decoy Server and Honeynets
- 8. • Physical • Real machines • Own IP Addresses • Often high-interactive • Virtual • Simulated by other machines that: – Respond to the traffic sent to the honeypots – May simulate a lot of (different) virtual honeypots at the same time Implementation
- 9. • Production honeypots are easy to use, capture only limited information, and are used primarily by companies or corporations • Prevention • To keep the bad elements out • There are no effective mechanisms • Deception, Deterrence, Decoys do NOT work against automated attacks: worms, auto-rooters, mass-rooters • Detection • Detecting the burglar when he breaks in • Response • Can easily be pulled offline Production
- 10. • Research honeypots are complex to deploy and maintain, capture extensive information, and are used primarily by research, military, or government organizations. • Collect compact amounts of high value information • Discover new Tools and Tactics • Understand Motives, Behavior, and Organization • Develop Analysis and Forensic Skills Research
- 11. Advantages • Small data sets of high value. • Easier and cheaper to analyze the data • Designed to capture anything thrown at them, including tools or tactics never used before • Require minimal resources • Work fine in encrypted or IPv6 environments • Can collect in-depth information • Conceptually very simple
- 12. Disadvantages • Can only track and capture activity that directly interacts with them • All security technologies have risk • Building, configuring, deploying and maintaining a high- interaction honeypot is time consuming • Difficult to analyze a compromised honeypot • High interaction honeypot introduces a high level of risk • Low interaction honeypots are easily detectable by skilled attackers
- 13. Working of Honeynet – High – interaction honeypot • Honeynet has 3 components: Data control Data capture Data analysis
- 14. Working of Honeyd – Low – interaction honeypot Open Source and designed to run on Unix systems Concept - Monitoring unused IP space
- 15. Conclusion • Not a solution! • Can collect in depth data which no other technology can • Different from others – its value lies in being attacked, probed or compromised • Extremely useful in observing hacker movements and preparing the systems for future attacks
