Learning About the Adversary

The evolving nature of the tactics, techniques, and procedures used by cyber adversaries have made signature and template based methods of modeling adversary behavior almost infeasible. We are moving into an era of data-driven autonomous cyber defense agents that learn contextually meaningful adversary behaviors from observables. In this chapter...

Pipe failure modelling for water distribution networks using boosted decision trees

Pipe failure modelling is an important tool for strategic rehabilitation planning of urban water distribution infrastructure. Rehabilitation predictions are mostly based on existing network data and historical failure records, both of varying quality. This paper presents a framework for the extraction and processing of such data to use it for...

The Role of Hosting Providers in Web Security: Understanding and Improving Security Incentives and Performance via Analysis of Large-scale Incident Data

In theory, hosting providers can play an important role in fighting cybercrime and misuse. This is because many online threats, be they high-profile or mundane, use online storage infrastructure maintained by hosting providers at the core of their criminal operations. <br/>However, in practice, we see large differences in the security measures...

Built environment and car travel: Analyses of interdependencies

An academic and policy debate has been running in recent decades on whether and to what extent travel behaviour is influenced by the built environment. This dissertation addresses this influence on daily travel distance, chaining behaviour, car ownership, and car commuting. As cars are the dominant mode of transport, car travel received most...
