The static nature of current IT systems gives attackers the extremely valuable advantage of time, as adversaries can take their time and plan attacks at their leisure. Although cloud infrastructures have increased the automation options for managing IT systems, the introduction of Moving Target Defense (MTD) techniques at the entire IT system level is still very challenging. The core idea of MT...

The classification of targets by the use radars has received great interest in recent years, particular defence and military applications, which development sensor systems that are able to identify classify threatening is a mandatory requirement. In specific case drones, several techniques have already been proposed and, up now, most effective technique was considered be micro-Doppler analysis ...

This paper proposes a Software-Defined Network (SDN)-based Moving Target Defense (MTD) to protect the network from potential scans in compromised network. As unique feature, contrary traditional MTDs, proposed MTD can work alongside other tools and countermeasures already deployed (e.g., Intrusion Protection Detection Systems) without affecting its behavior. Through extensive evaluation, we sho...

Architecture-Based Self-Adaptation for Moving Target Defense Report Title The fundamental premise behind Moving Target Defense (MTD) is to create a dynamic and shifting system that is more difficult to attack than a static system because a constantly changing attack surface at least reduces the chance of an attacker finding and exploiting the weakness. However, MTD approaches are typically chos...

Based on the sparsity of scene (moving target and few scatterers on the same resolution cell), MTD and 3D imaging are investigated by means of compressed sensing (CS) for airship sparse array radar and airborne three-aperture MMW SAR. Based on the sparsity of continuous scene sparse spectrum, sidelooking 3D imaging is investigated by means of CS for airborne cross-track sparse array SAR. Some s...

in this paper, the detection of moving targets in airborne widely separated phased multiple input multiple output (mimo) radars which are located on moving platform is investigated. in order to derive the detector, the generalized likelihood ratio test is applied. the proposed detection rule, exploits the clutter subspace information and its maximum likelihood estimation, to improve the detecti...

Context: Internet-of-Things (IoT) systems are increasingly deployed in the real world, but their security lags behind state of art non-IoT systems. Moving target defense (MTD) is a cyberdefense paradigm, successfully implemented conventional systems, that could improve IoT security. Objective: Identify and synthesize existing MTD techniques for validate feasibility as cybersecurity paradigm sui...

We study moving-target defense (MTD) that actively perturbs transmission line reactances to thwart stealthy false data injection (FDI) attacks against state estimation in a power grid. Prior work on this topic has proposed MTD based on randomly selected reactance perturbations, but these perturbations cannot guarantee effective attack detection. To address the issue, we present formal design cr...
