Simulating Malware with MAlSim
PublikacjaThis paper describes MAlSim - Mobile Agent Malware Simulator - a mobile agent framework developed to address one of the most important problems related to the simulation of attacks against information systems i.e. the lack of adequate tools for reproducing behaviour of malicious software (malware). The framework can be deployed over the network of an arbitrary information system and it aims at simulating behaviour of each instance...

MAlSim - Mobile Agent Malware Simulator
PublikacjaOne of the problems related to the simulation of attacks against critical infrastructures is the lack of adequate tools for the simulation of malicious software (malware). Malware attacks are the most frequent in the Internet and they pose a serious threat against critical networked infrastructures. To address this issue we developed Mobile Agent Malware Simulator (MAISim). The framework uses the technology of mobile agents and...

Modelling the malware propagation in mobile computer devices
PublikacjaNowadays malware is a major threat to the security of cyber activities. The rapid develop- ment of the Internet and the progressive implementation of the Internet of Things (IoT) increase the security needs of networks. This research presents a theoretical model of malware propagation for mobile computer devices. It is based on the susceptible-exposed- infected-recovered-susceptible (SEIRS) epidemic model. The scheme is based on...

Empirical Analysis of Forest Penalizing Attribute and Its Enhanced Variations for Android Malware Detection
PublikacjaAs a result of the rapid advancement of mobile and internet technology, a plethora of new mobile security risks has recently emerged. Many techniques have been developed to address the risks associated with Android malware. The most extensively used method for identifying Android malware is signature-based detection. The drawback of this method, however, is that it is unable to detect unknown malware. As a consequence of this problem,...

Zagrożenia bezpieczeństwa IT/OT
PublikacjaZłośliwe oprogramowanie, obok ataków rozproszonej odmowy świadczenia usług (ang. Distributed Denial of Servi-ce – DDoS), podszywania, SPAMu oraz ogólnie niechcianej komunikacji, stanowi aktualnie jedną z najważniejszych kwestii bezpieczeństwa. Sam termin (Malicious Software – Malware) określa zbiorczo między innymi wirusy, konie trojańskie i robaki komputerowe. Ostateczne rozwiązanie wspomnianych zagrożeń bezpieczeństwa wymaga...
