Lecture Notes: IT Security - Using Deception Techniques

Introduction

• Importance of preventing unauthorized access to systems.
• Utilize security knowledge to create deception and disrupt attackers.

Honeypots

• Definition: A tool to attract attackers and observe their methods.
• Purpose: Engage attackers to understand their techniques, often automated.
• Functionality: Virtual environments that imitate real systems but are isolated from production.

Building a Honeypot

• Can use commercial or open-source software packages.
• Create non-production virtual worlds to attract attackers.
• Challenges: Continuous upgrade to beat attackers' ability to recognize honeypots.

Honey Nets

• Definition: Larger infrastructures composed of multiple honeypots.
• Components: Workstations, servers, routers, firewalls.
• Goal: Create realistic environments to engage attackers longer.

Honey Files

• Definition: Files with fake or seemingly important information.
• Examples: Files named password.txt containing false data.
• Monitoring and Alerts: Alerts if accessed inappropriately in the network.

Honey Tokens

• Definition: Traceable data added to networks for monitoring leaks.
• Examples:
  • Fake API credentials on public clouds.
  • Fake email addresses for tracking unauthorized distribution.
• Application: Any falsified data for tracking, like database records to browser cookies.

Conclusion

• Honeypots, honey nets, honey files, and honey tokens are tools for deception.
• Aim to learn about attackers' methods and protect real systems.
• Continuous improvement and monitoring are critical for effectiveness.
