We propose interdependent defense (IDD) games, a computational game-theoretic framework to study aspects of the interdependence of risk and security in multi-agent systems under deliberate external attacks. Our model builds upon interdependent security (IDS) games, a model by Heal and Kunreuther...

Security researchers agree that security control is a difficult to observe credence quality of online services that Internet users cannot easily assess through research or experience. Yet there is evidence that users form perceptions of security control that strongly determine how much trust...

Computer crime, also referred as cyber-crime, is considered today one of the main leading problems in the ongoing global economic crisis and an impediment in the development of many countries. Objectives of this work are: to determine the evolution of cyber-crime during the current economic...

Internet worm attacks have become increasingly more frequent and have had a major impact on the economy, making the detection and prevention of these attacks a top security concern.
