Search for a Moving Target
… model of a discrete sequential search for a target moving in discrete space is given. The model is based on a Bayesian updating algorithm giving successive probability distributions of target position at intervals throughout the search. Updating allows for target movement and for negative …

Evolutionary Strategies for Secure Moving Target Configuration Discovery
Defense against many cyber security threats can be implemented with existing software on the machine, without requiring patches for current programs or the installation of specialized security software. There are certain operating system or program parameters which, if set properly, can close …

Design, Implementation and Experiments for Moving Target Defense Framework
The traditional defensive security strategy for distributed systems employs well-established defensive techniques such as; redundancy/replications, firewalls, and encryption to prevent attackers from taking control of the system. However, given sufficient time and resources, all these methods can …

Implementation of network moving target defense in embedded systems
<p>Moving target defense provides opportunities for adaptive defense in embedded systems. A great deal of work has been done on incorporating moving target defense techniques into enterprise systems to increase the cost to attackers and level the playing field. A smaller body of work focuses on …

Prediction of user action in moving-target selection tasks
<p>Selection of moving targets is a common task in human–computer interaction (HCI), and more specifically in virtual reality (VR). In spite of the increased number of applications involving moving–target selection, HCI and VR studies have largely focused on static-target selection. Compared to its …

Control of a flexible space robot tracking a moving target
… payload and to dock smoothly with an orbiting target whose motion is either known or not known a priori. The dynamical equations for planar motion of the space robot are derived by means of Lagrange’s equations. They are then separated into two sets of equations suitable for rigid-body maneuver …

Micro-Moving Target IPv6 Defense for 6LoWPAN and the Internet of Things
… are using IPv6 addressing, we seek to adapt a moving-target defense measure called Moving Target IPv6 Defense for use with embedded devices in order to add an additional layer of security. This adaptation, which we call Micro-Moving Target IPv6 Defense, operates within IPv6 over Low power …

Cybersecurity for the Internet of Things: A Micro Moving Target IPv6 Defense
… for the IoT through the exploration of a moving target defense to apply for limiting the time attackers may conduct reconnaissance on embedded systems while considering the challenges presented from IoT devices such as resource and performance constraints. We introduce the design and …

RESONANT: Reinforcement Learning Based Moving Target Defense for Detecting Credit Card Fraud
… iterated game. This paper proposes an adaptive moving target defense (MTD) approach based on deep reinforcement learning (DRL), termed RESONANT to identify the optimal switching points to another ML classifier for credit card fraud detection. It identifies optimal moments to strategically switch …

Evaluation of Moving Target IPv6 Defense and Distributed Denial of Service Defenses
… machine that attempts to prevent the victim, the targeted machine, from communicating to other devices on the network or perform its normal tasks. The extension of these attacks to include many malicious machines became known as Distributed Denial-of-Service (DDoS) attacks. DDoS attacks cause an …

Distributed Location Estimation of a Moving Target Characterized by a Spatial Poisson Field
Wireless Sensor Networks (WSNs) are traditionally employed to collect spatial and temporal data characterizing various events. These data are then used to solve inference problems such as object detection, counting, classification, estimation and tracking. Distributed solutions provided by WSNs are …

Synthetic Aperture Radar Image Formation for the Moving -Target and Near -Field Bistatic Cases
Bistatic SAR imaging is more involved than the monostatic SAR case, because of the separation of the transmitter and the receiver, and possibly the changing bistatic geometry. For near-field bistatic SAR imaging, we develop a novel fast BP algorithm, motivated by a newly proposed fast BP algorithm …

Investigation of ground moving target indication techniques for a multi-channel synthetic aperture radar
… cars on a highway. In SAR, the radar platform is moving during the imaging period, hence everything that the radar illuminates has motion relative to the radar platform. In order to specifically detect objects on the ground that are moving relative to stationary ground objects (often termed …

Improving the Security, Privacy, and Anonymity of a Client-Server Network through the Application of a Moving Target Defense
… that occur at the network layer. A network-based moving target defense is a technique that obfuscates the location of a machine on the Internet by arbitrarily changing its IP address periodically. MT6D is one of these techniques that leverages the size of the IPv6 address space to make it …
