A Hierarchical Detection and Response System to Enhance Security Against Lethal Cyber-Attacks in UAV Networks

2018

International audience; Unmanned aerial vehicles (UAVs) networks have not yet received considerable research attention. Specifically, security issues are a major concern because such networks, which carry vital information, are prone to various attacks. In this paper, we design and implement a novel intrusion detection and response scheme, which operates at the UAV and ground station levels, to detect malicious anomalies that threaten the network. In this scheme, a set of detection and response techniques are proposed to monitor the UAV behaviors and categorize them into the appropriate list (normal, abnormal, suspect, and malicious) according to the detected cyber-attack. We focus on the m…

Cyber Security and the Internet of Things: Vulnerabilities, Threats, Intruders and Attacks

2015

Internet of Things (IoT) devices are rapidly becoming ubiquitous while IoT services are becoming pervasive. Their success has not gone unnoticed and the number of threats and attacks against IoT devices and services are on the increase as well. Cyber-attacks are not new to IoT, but as IoT will be deeply interwoven in our lives and societies, it is becoming necessary to step up and take cyber defense seriously. Hence, there is a real need to secure IoT, which has consequently resulted in a need to comprehensively understand the threats and attacks on IoT infrastructure. This paper is an attempt to classify threat types, besides analyze and characterize intruders and attacks facing IoT device…

The Cyberspace Threats and Cyber Security Objectives in the Cyber Security Strategies

2013

Threats in cyberspace can be classified in many ways. This is evident when you look at cyber security on a multinational level. One of the most common models is a threefold classification based on motivational factors. Most nations use this model as a foundation when creating a strategy to handle cyber security threats as it pertains to them. This paper will use the five level model: cyber activism, cybercrime, cyber espionage, cyber terrorism and cyber warfare. The National Cyber Security Strategy defines articulates the overall aim and objectives of the nation's cyber security policy and sets out the strategic priorities that the national government will pursue to achieve these objectives…

Una strategia nazionale a difesa del Cyberspazio

2023

L’articolo intende proporre un’analisi circa lo stato dell’arte della sicurezza ci- bernetica in Italia, prestando particolare attenzione alle principali novità conte- nute all’interno della Strategia Nazionale di Cybersicurezza 2022-2026. Nello specifico, dopo aver offerto un inquadramento giuridico del fenomeno degli at- tacchi informatici, il contributo intende approfondire con una visione critica le future sfide che vedranno l’Italia e l’Europa protagoniste nella difesa del pro- prio “dominio cibernetico”. The article intends to propose an analysis about the state of the art of cyber security in Italy, paying particular attention to the main innovations contained in the National Cyberse…

E-health systems in digital environments

2019

As we live in the digital world, people can be provided with more effective treatment methods that allow them to live longer in their home and to live there better. People can be provided with better home care and preventive health care. People can easily carry portable sensors and intelligent devices in their bodies and wrists that relay their vital information to hospital systems in real time, from which healthcare staff can track human vitality even in real time. Although the digital world offers good opportunities to improve healthcare systems and make disease analyses more effective, we must look deeper about that issue. Devices and systems may not work well together. Almost every manu…

AI-based quantum-safe cybersecurity automation and orchestration for edge intelligence in future networks

2023

The AIQUSEC (AI-based quantum secure cyber security automation and orchestration in the edge intelligence of future networks) brings measurable advances to the cyber security of access and edge networks and their services, as well as Operational Service Technologies (OT). The research aims for significant cybersecurity scalability, efficiency, and effectiveness of operations through improved and enhanced device and sensor securities, security assurance, quantum security, and Artificial Intelligence (AI) based automation solutions. The new application scenarios of near future, the multiple stakeholders within each scenario, and the higher data volumes raise the need for novel cybersecurity s…

APT Cyber-attack Modelling: Building a General Model

2022

The global community continues to experience an increase in the scale, sophistication, and successful perpetration of cyber-attacks. As the quantity and value of electronic information have increased, so too have the efforts of criminals and other malicious actors who have embraced the Internet as a more anonymous, convenient, and profitable way of carrying out their activities. The systems are attacked more and more by single or multiple hacktivists, state sponsored hackers, cyber criminals, cyber terrorists, cyber spies, or cyber warfare warfighters. The cyber security approach requires a balance of cyber threat intelligence, real time cyber-attack detection and especially the cyber early…

Vulnerability Analysis of Interdependent Critical Infrastructures upon a Cyber-attack

Semi-supervised deep learning-driven anomaly detection schemes for cyber-attack detection in smart grids

2022

Modern power systems are continuously exposed to malicious cyber-attacks. Analyzing industrial control system (ICS) traffic data plays a central role in detecting and defending against cyber-attacks. Detection approaches based on system modeling require effectively modeling the complex behavior of the critical infrastructures, which remains a challenge, especially for large-scale systems. Alternatively, data-driven approaches which rely on data collected from the inspected system have become appealing due to the availability of big data that supports machine learning methods to achieve outstanding performance. This chapter presents an enhanced cyber-attack detection strategy using unlabeled…
