HALE-IoT: HArdening LEgacy Internet-of-Things devices by retrofitting defensive firmware modifications and implants
2022
Internet-Of-Things (IoT) devices and their firmware are notorious for their lifelong vulnerabilities. As device infection increases, vendors also fail to release patches at a competitive pace. Despite security in IoT being an active area of research, prior work has mainly focused on vulnerability detection and exploitation, threat modelling, and protocol security. However, these methods are ineffective in preventing attacks against legacy and End-Of-Life devices that are already vulnerable. Current research mainly focuses on implementing and demonstrating the potential of malicious modifications. Hardening emerges as an effective solution to provide IoT devices with an additional layer of d…
Cyber warfare : the game changer in the battlespace
2022
A recent development in warfare has been the integration of Electronic Warfare (EW), Information Warfare (IW) and Cyber Warfare (CW) systems designed to generate non-kinetic effects in battle space together with the traditional use of kinetic weapons. These new capacities of armed forces create new possibilities to achieve the goals of war. These advanced and new capabilities form a whole new non-kinetic environment in which they have become a game changer in battle space. This article focuses on describing cyber warfare and the first experiences of the war in Ukraine. nonPeerReviewed
Leveraging the benefits of big data with fast data for effective and efficient cybersecurity analytics systems : A robust optimisation approach
2020
In recent times, major cybersecurity breaches and cyber fraud within the public and private sectors are making international headlines. Majority of organisations are facing cybersecurity adversity and advanced threats. On the one hand, we have asynchronous cybersecurity practices, many standards and frameworks to consider while on the other hand, we have to deal and secure our organisations against cyber-criminals, organised hacktivists, insider threats, hackers and nation-states with malafide intentions. The Center for Cyber Safety and Education's Global Information Security Workforce Study (GISWS) confirms that globally we are not only loosing but also backpedalling against threats and ri…
Data Mining for the Security of Cyber Physical Systems Using Deep-Learning Methods
2022
Cyber Physical Systems (CPSs) have become widely popular in recent years, and their applicability have been growing exponentially. A CPS is an advanced system that incorporates a computation unit along with a hardware unit, allowing for computing processes to interact with the physical world. However, this increased usage has also led to the security concerns in them, as they allow potential attack vendors to exploit the possibilities of committing misconduct for their own benefit. It is of paramount importance that these systems have comprehensive security mechanisms to mitigate these security threats. A typical attack vector for a CPS is malicious data supplied by compromised sensors that…
On the (In)Security of 1090ES and UAT978 Mobile Cockpit Information Systems : An Attacker Perspective on the Availability of ADS-B Safety- and Missio…
2022
Automatic dependent surveillance-broadcast (ADS-B) is a key air surveillance technology and a critical component of next-generation air transportation systems. It significantly simplifies aircraft surveillance technology and improves airborne traffic situational awareness. Many types of mobile cockpit information systems (MCISs) are based on ADS-B technology. MCIS gives pilots the flight and traffic-related information they need. MCIS has two parts: an ADS-B transceiver and an electronic flight bag (EFB) application. The ADS-B transceivers transmit and receive the ADS-B radio signals while the EFB applications hosted on mobile phones display the data. Because they are cheap, lightweight, an…
Protecting the besieged cyber fortress : Russia’s response to cyber threats
2019
The Information Security Doctrine of the Russian Federation (RF) defines the threat to information security as a complex of actions and factors that represent a danger to Russia in the information space. These threats can be information-psychological (i.e., when the adversary tries to influence a person’s mind) or information-technical (i.e., when the object of influence is the information infrastructure). The information infrastructure of the RF is a combination of information systems, websites, and communication networks located in the territory of the RF, or those used as part of international treaties signed by the RF. A cyber threat is an illegal penetration or threat of penetration by…
On Attacking Future 5G Networks with Adversarial Examples : Survey
2022
The introduction of 5G technology along with the exponential growth in connected devices is expected to cause a challenge for the efficient and reliable network resource allocation. Network providers are now required to dynamically create and deploy multiple services which function under various requirements in different vertical sectors while operating on top of the same physical infrastructure. The recent progress in artificial intelligence and machine learning is theorized to be a potential answer to the arising resource allocation challenges. It is therefore expected that future generation mobile networks will heavily depend on its artificial intelligence components which may result in …
Adversarial Attack’s Impact on Machine Learning Model in Cyber-Physical Systems
2020
Deficiency of correctly implemented and robust defence leaves Internet of Things devices vulnerable to cyber threats, such as adversarial attacks. A perpetrator can utilize adversarial examples when attacking Machine Learning models used in a cloud data platform service. Adversarial examples are malicious inputs to ML-models that provide erroneous model outputs while appearing to be unmodified. This kind of attack can fool the classifier and can prevent ML-models from generalizing well and from learning high-level representation; instead, the ML-model learns superficial dataset regularity. This study focuses on investigating, detecting, and preventing adversarial attacks towards a cloud dat…
National cyber threat prevention mechanism as a part of the E-EWS
2020
The research will find out feature-based functionalities concerning the national cybersecurity system HAVARO and how the system is possible to implement to the EU level early warning system. The research based on interviews, official materials concerning the HAVARO information sharing system, scientific literature and other official published documents. The European level decision-makers have recognized that lack of cooperation between EU member countries effects to completely public safety atmosphere. The only problem does not consist of separate operational functions and procedures between national Cyber situation centers. One main problem is that the European Union does not have a common…
Cyber security of vehicle CAN bus
2019
There are currently many research projects underway concerning the intelligent transport system (ITS), with the intent to develop a variety of communication solutions between vehicles, roadside stations and services. In the near future, the roll-out of 5G networks will improve short-range vehicle-to-vehicle traffic and vehicle-to-infrastructure communications. More extensive services can be introduced due to almost non-delayed response time. Cyber security is central for the usability of the services and, most importantly, for car safety. The Controller Area Network (CAN) is an automation bus that was originally designed for real-time data transfer of distributed control systems to cars. La…
