ABSTRACT
Autonomic networks are adaptive and self-organizing, and as a consequence, securing such networks is crucial. Most security schemes suggested for autonomic networks, for example, MANETs tend to build upon some fundamental assumptions regarding the trustworthiness of the participating hosts and the underlying networking system. If autonomic network is to achieve the same level of acceptance as traditional wired and wireless network infrastructures, then a framework for trust management must become an integral part of its infrastructure. The main goal of this chapter is to highlight critical issues that impinge on trust management and to detail the approaches used
