Moving-target defense has been hypothesized as a potential game changer in cyber defense, including that for computer networks. However there has been little work to study how much proactively changing a network’s configuration can increase the difficulty for attackers and thus improve the resilience of the system under attack. In this paper we present a basic design schema of a movingtarget network defense system. Based on this design schema, we conducted a simulation-based study to investigate the degree to which proactively changing a network’s various parameters can decrease an adversary’s chance for success. We believe this is an important first step towards understanding why and how the concept of a moving target can be successfully applied to computer network defenses. 1

A multi-tier, multi-craft mission architecture has been proposed but, despite its apparent promise, limited use and testing of the architecture has been conducted. This paper proposes and details a mission concept and its implementation for testing this architecture in the terrestrial environment. It is expected that this testing will allow significant refinement of the proposed architecture as well as providing data on its suitability for use in both terrestrial and extra-terrestrial applications. Logistical and technical challenges with this testing are discussed. I. MAJOR HEADINGS Fink [1, 2] and others [3, 4] have proposed the use of teams of multiple robots in the exploration of planets and for other applications. These multi-robot teams could (and it would seem, generally, would) include robots of various configurations. Under Fink’s concept, robots would be separated in to tiers based on their scope of influence. Specifically, orbital, flying and ground-based tiers are defined. Each tier would exert influence over tiers of lesser range by selecting points of

Abstract- An autonomic system provides self-adaptive ability that enables system to dynamically adjust its behavior on environmental changes or system failure. Fundamental process of adaptive behavior in an autonomic system is consist of monitoring system or/and environment information, analyzing monitored information, planning adaptation policy and executing selected policy. Evaluating system utility is one of a significant part among them. We propose a novel approach on evaluating autonomic system at runtime. Our proposed method takes advantage of a goal model that has been widely used at requirement elicitation phase to capture system requirements. We suggest the state-based goal model that is dynamically activated as the system state changes. In addition, we defined type of constraints that can be used to evaluate goal satisfaction level. We implemented a prototype of autonomic computing software engine to verity our proposed method. We simulated the behavior of the autonomic computing engine with the home surveillance robot scenario and observed the validity of our proposed method Index Terms—autonomic computing, adaptive systems, goal model, embedded system I.
