  1. 26. Man in The Middle Attacks on Software Defined Network

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Eskil Christensson; [2023]
    Nyckelord :;

    Sammanfattning : Software Defined Networking (SDN) is a method of abstracting the network to ease administration by centralizing it. Doing this removes intelligence from the devices and this might open up local security vulnerabilities. LÄS MER

  3. 27. Cyber Threat Detection using Machine Learning on Graphs : Continuous-Time Temporal Graph Learning on Provenance Graphs

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jakub Reha; [2023]
    Nyckelord :Graph neural networks; Temporal graphs; Benchmark datasets; Anomaly detection; Heterogeneous graphs; Provenance graphs; Grafiska neurala nätverk; temporala grafer; benchmark-datauppsättningar; anomalidetektering; heterogena grafer; härkomstgrafer;

    Sammanfattning : Cyber attacks are ubiquitous and increasingly prevalent in industry, society, and governmental departments. They affect the economy, politics, and individuals. LÄS MER

  4. 28. Hidden Markov Models for Intrusion Detection Under Background Activity

    Master-uppsats, KTH/Matematisk statistik

    Författare :Robert Siridol-Kjellberg; [2023]
    Nyckelord :Hidden Markov models; Cyber security; Intrusion detection; Clustering; Background subtraction; Dolda Markovmodeller; Cybersäkerhet; Dataintrång; Klustring; Bakgrundssubtraktion;

    Sammanfattning : Detecting a malicious hacker intruding on a network system can be difficult. This challenge is made even more complex by the network activity generated by normal users and by the fact that it is impossible to know the hacker’s exact actions. LÄS MER

  5. 29. Third-party risks in industrial control systems: : A case study in the wind power sector

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Abdullahi Ahmed; [2023]
    Nyckelord :Supply chain security; Wind power; Risk management; Third-party risk management; SCADA-system; Säkerhetshantering för försörjningskedjan; Vindkraft; Riskhantering; Tredjeparts riskhantering; SCADA-system;

    Sammanfattning : This report investigates third-party risk for SCADA systems, using Swedish wind power as an empirical case study. Supervisory, Control, and Data Acquisition (SCADA) systems are used in the wind power industry to monitor and control the operational process. The paper also proposed potential strategies for reducing third-party risks and exposures. LÄS MER

  7. 30. Observability in Machine Learning based Intrusion Detection Systems for RPL-based IoT

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Malin Strand; [2023]
    Nyckelord :;

    Sammanfattning : As IoT devices become more and more present in our daily lives, security in IoT networks has become a major concern. A promising approach for detecting attacks is the use of machine learning based Intrusion Detection Systems (IDSs). The attack studied in this thesis is the blackhole attack, an attack causing parts of the network to disconnect. LÄS MER
