1. 6. A method of detecting and predicting attack vectors based on genetic programming

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Yekatierina Churakova; Oleksii Novikov; [2023]
   Nyckelord :MITTRE ATT CK; genetic programming; attack vectors; attack prediction;

   Sammanfattning : This Master's thesis presents a novel approach for detecting and predicting attack vectors based on genetic programming. The proposed method utilizes a genetic algorithm to evolve a set of rules that predict attack vectors over the system based on caught indicators of compromise. LÄS MER

3. 7. Learning Policies for Path Selection in Attack Graphs

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

   Författare :Manuel Rickli; [2022]
   Nyckelord :;

   Sammanfattning : IT systems are indispensable nowadays. With thousands of hacking attempts happening daily, cyber defense mechanisms are crucial for maintaining a working state of those systems. Simulating an attacker is a means of preparing for future hacking attacks by determining the most likely vulnerabilities where an attack could be attempted. LÄS MER

4. 8. The Internal Mechanisms of an International Arms Trade Network - The Case Study of Armscor Global Defense : The applicable network perspective of the Uppsala model for a multinational enterprise.

   Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Albin Brahimi; Danielle Lee; [2022]
   Nyckelord :Innovation; entrepreneurship; arm dealers; defense sector; internationalization; globalization; networking theory; Uppsala model; risk management;

   Sammanfattning : The process by which a firm internationalizes has long been a topic of discussion in academia. Several models, hypotheses, and theories have been created to explain how a company expands and sells its products to a new market. However, each industry and pathway to internationalization has yet to be explored. LÄS MER

5. 9. The Binding Mechanism of Carbapenems in the Class A beta-lactamase IMI-1 : A Molecular Dynamics Study of Ligand Stability

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Biokemi

   Författare :Isabell Lindahl; [2022]
   Nyckelord :antibiotic resistance; IMI-1; betalactamase; Carbapenemase; free energy; LIE; linear interaction energy; β-lactamase; meropenem; biapenem; imipenem; active site;

   Sammanfattning : Antibiotic resistance is a global and accelerating matter. Over time, the bacteria have evolved several defense mechanisms against the antibiotics. One of the defense mechanisms is that the bacteria can produce enzymes with the ability to hydrolyze the characteristic b-lactam ring of the antibiotics. These enzymes are called b-lactamases.

7. 10. A Game-theoretical Framework for Byzantine-Robust Federated Learning

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

   Författare :Wanyun Xie; [2022]
   Nyckelord :Game theory; distributed robust learning; training-time attacks; exploration-exploitation tradeoff; Spelteori; distribuerad robust inlärning; attacker på träningstiden; kompromiss mellan utforskning och exploatering;

   Sammanfattning : The distributed nature of Federated Learning (FL) creates security-related vulnerabilities including training-time attacks. Recently, it has been shown that well-known Byzantine-resilient aggregation schemes are indeed vulnerable to an informed adversary who has access to the aggregation scheme and updates sent by clients.
