A New Hybrid Approach for Infrastructure Discovery, Monitoring and Control

Presented at DEF CON 13 (2005), July 30, 2005, 8 p.m. (50 minutes)

An enterprise IT infrastructure is a complex and a dynamic environment that is generally described as a black hole by its IT managers. The knowledge about an enterprise network's layout (topology), resources (availability and usage), elements residing on the network (devices, applications, their properties and the interdependencies among them) as well as the ability to maintain this knowledge up-to-date, are all of critical for managing and securing IT assets and resources. Unfortunately, the current available network discovery technologies (active network discovery and passive network discovery) suffer from numerous technological weaknesses which prevent them from providing with complete and accurate information about an enterprise IT infrastructure. Their ability to keep track of changes is unsatisfactory at best. The inability to "know" the network directly results with the inability to manage and secure the network in an appropriate manner. This is since it is impossible to manage or to defend something, or against something, its existence is unknown or that only partial information about it exists. The first part of the talk presents the current available network discovery technologies, active network discovery and passive network discovery, and explains their strengths and weaknesses. The talk highlights technological barriers, which cannot be overcome, with open source and commercial applications using these technologies. The second part of the talk presents a new hybrid approach for infrastructure discovery, monitoring and control. This agent-less approach provides with real-time, complete, granular and accurate information about an enterprise infrastructure. The underlying technology of the solution enables maintaining the information in real-time, and ensures the availability of accurate, complete and granular network context for other network and security applications. During the talk new technological advancements in the fields of infrastructure discovery, monitoring and auditing will be presented.
