This book constitutes the refereed proceedings of the 6th IFIP WG 6.6 International Conference on Autonomous Infrastructure, Management, and Security, AIMS 2012, held in Luxembourg in June 2012. The 10 full papers presented were carefully reviewed and selected from 23 submissions. They cover autonomic and distributed management, network security, network monitoring, and special environments and Internet of Things. In addition, this book contains 9 workshop papers which were selected from 18 submissions. They deal with high-speed networks and network management, intrusion detection, and network monitoring and security.

This volume of the Lecture Notes in Computer Science series contains the papers accepted for presentation at the Third International Conference on Autonomous - frastructure, Management and Security (AIMS 2009). The conference took place in Enschede, The Netherlands, hosted by the University of Twente. AIMS 2009 was - ganized and supported by the EC IST-EMANICS Network of Excellence (#26854) and co-sponsored by IFIP WG 6.6 and the Strategic Research Orientation of the University of Twente on Dependable Systems and Networks (DSN). AIMS 2009 constituted the Third edition of a single-track and standalone c- ference on management and security aspects of distributed and autonomous systems, which took place initially in Oslo, Norway in June 2007, followed by AIMS 2008 in Bremen, Germany. The theme of the AIMS 2009 conference was "Scalability of Networks and S- vices," focusing on how scalable networked systems can be monitored, managed, and protected in an ef cient and autonomous way. The research papers that have been - lected for publication in the present proceedings have approached this theme from d- ferent perspectives, covering topics such as network resource management, overlays andpeer-to-peernetworks,networkcon gurationandoptimization,andmonitoringand visualization.
