Economic aspects of information protection under present large-scale cyber-attacks conditions

Identifying cyber attacks under local model information

This work considers the problem of detecting corrupted components as well as external attacks in a large scale decentralized system. The electric power system, the transportation system, and generally any computer or network system are examples of large scale systems for which cyberattacks have become an important threat. Despite the recent advances in the theory of detection and identification...

Information Warfare How to Survive Cyber Attacks

Cyber Stealth Attacks in Critical Information Infrastructures

Current Critical Infrastructures (CIs) are complex interconnected industrial systems that, in recent years, have incorporated information and communications technologies such as connection to the Internet and commercial off-the-shelf components. This makes them easier to operate and maintain, but exposes them to the threats and attacks that inundate conventional networks and systems. This paper...

Large-scale classification of traffic signs under real-world conditions

Traffic sign inventories are important to governmental agencies as they facilitate evaluation of traffic sign locations and are beneficial for road and sign maintenance. These inventories can be created (semi-)automatically based on street-level panoramic images. In these images, object detection is employed to detect the signs in each image, followed by a classification stage to retrieve the s...

Protection of flows under targeted attacks

Due to the importance of robustness in many real-world optimization problems, the field of robust optimization has gained a lot of attention over the past decade. We concentrate on maximum flow problems and introduce a novel robust optimization model which, compared to known models from the literature, features several advantageous properties: (i) We consider a general class of path-based flow ...
