This paper provides an examination of an emerging class of security mechanisms often referred to as deception technologies or honeypots. It is based on our experience over the last four years designing and building a high, end commercial deception system called ManTrap. The paper will provide an overview of the various technologies and techniques and will examine the strengths and weaknesses of each approach. It will discuss deployment criteria and strategies and will provide a summary of our experiences designing and constructing these systems. It also presents the results of work demonstrating the feasibility and utility of a deep deception honeypot.
