The proposition of balanced and explainable surrogate method for network intrusion detection in streamed real difficult data

Mateusz Szczepanski, Mikołaj Komisarek, Marek Pawlicki,Rafał KozikMichał Choraś

Handling the data imbalance problem is one of the crucial steps in a machine learning pipeline. The research community is well aware of the effects of data imbalance on machine learning algorithms. At the same time, there is a rising need for explainability of AI, especially in difficult, high-stake domains...More>>

Preprocessing Pipelines Including Block-Matching Convolutional Neural Network for Image Denoising to Robustify Deep Reidentification against Evasion Attacks

Marek Pawlicki, Ryszard S. Choraś

Artificial neural networks have become the go-to solution for computer vision tasks, including problems of the security domain. One such example comes in the form of reidentification, where deep learning can be part of the surveillance pipeline. The use case necessitates considering an adversarial setting—and neural networks have been shown...More>>

Hybroid: Toward Android Malware Detection and Categorization with Program Code and Network Traffic

Mohammad Reza Norouzian, Peng Xu, Claudia Eckert, and Apostolis Zarras

Android malicious applications have become so sophisticated that they can bypass endpoint protection measures. Therefore, it is safe to admit that traditional anti-malware techniques have become cumbersome, thereby raising the need to develop efficient ways to detect Android malware. In this paper, we present Hybroid, a hybrid Android malware detection...More>>

Development of the Information Security Management System Standard for Public Sector Organisations in Estonia

Mari Seeba, Raimundas Matulevičius, and Ilmar Toom

Standardisation gives us a common understanding or processes to do something in a commonly accepted way. In information security management, it means to achieve the appropriate security level in the context of known and unknown risks. Each government’s goal should be to provide digital services to its citizens with the...More>>

Security Risk Estimation and Management in Autonomous Driving Vehicles

Abasi-amefon O. Affia, Raimundas Matulevičius, and Rando Tõnisson

Autonomous vehicles (AV) are intelligent information systems that perceive, collect, generate and disseminate information to improve knowledge to act autonomously and provide its required services of mobility, safety, and comfort to humans. This paper combines the security risk management (ISSRM) and operationally critical threat, asset, and vulnerability evaluation (OCTAVE allegro) methods...More>>

Information Security Analysis in the Passenger-Autonomous Vehicle Interaction

Mariia Bakhtina, Raimundas Matulevičius

Autonomous vehicles (AV) are becoming a part of humans’ everyday life. There are numerous pilot projects of driverless public buses; some car manufacturers deliver their premium-level automobiles with advanced self-driving features. Thus, assuring the security of a Passenger–Autonomous Vehicle interaction arises as an important research topic, as along with opportunities,...More>>

Risk-Oriented Design Approach For Forensic-Ready Software Systems

Lukas Daubner, Raimundas Matulevičius

Digital forensic investigation is a complex and time-consuming activity in response to a cybersecurity incident or cybercrime to answer questions related to it. These typically are what happened, when, where, how, and who is responsible. However, answering them is often very laborious and sometimes outright impossible due to a lack...More>>

A Novel Approach for Network Intrusion Detection Using Multistage Deep Learning Image Recognition

Toldinas, Jevgenijus, Algimantas Venčkauskas, Robertas Damaševičius, Šarūnas Grigaliūnas, Nerijus Morkevičius, and Edgaras Baranauskas

The current rise in hacking and computer network attacks throughout the world has heightened the demand for improved intrusion detection and prevention solutions. The intrusion detection system (IDS) is critical in identifying abnormalities and assaults on the network, which have grown in size and pervasiveness. The paper proposes a novel...More>>

Method for Dynamic Service Orchestration in Fog Computing

Morkevicius, Nerijus, Algimantas Venčkauskas, Nerijus Šatkauskas, and Jevgenijus Toldinas

Fog computing is meant to deal with the problems which cloud computing cannot solve alone. As the fog is closer to a user, it can improve some very important QoS characteristics, such as a latency and availability. One of the challenges in the fog architecture is heterogeneous constrained devices and...More>>
