Abstract-This paper describes the Infrastructure and Network Description Language (INDL). The aim of INDL is to provide technology independent descriptions of computing infrastructures. These descriptions include the physical resources and the network infrastructure that connects these resources. The description language also provides the necessary vocabulary to describe virtualization of resources and the services offered by these resources. Furthermore, the language can be easily extended to describe federation of different existing computing infrastructures, specific types of (optical) equipment and also behavioral aspects of resources, for example, their energy consumption.Before we introduce INDL we first discuss a number of modeling efforts that have lead to the development of INDL, namely the Network Description Language, the Network Markup Language and the CineGrid Description Language. We also show current applications of INDL in two EU-FP7 projects: NOVI and GEYSERS. We demonstrate the flexibility and extensibility of INDL to cater the specific needs of these two projects.

In the computer science field coordinated vulnerability disclosure is a well-known practice for finding flaws in ITsystems and patching them. In this practice, a white-hat hacker who finds a vulnerability in an IT-system reports that vulnerability to the system's owner. The owner will then resolve the problem, after which the vulnerability will be disclosed publicly. This practice generally does not focus on potential offenders or black-hat hackers who would likely exploit the vulnerability instead of reporting it. In this paper, we take an interdisciplinary approach and review the current coordinated vulnerability disclosure practice from both a computer science and criminological perspective. We discuss current issues in this practice that could influence the decision to use coordinated vulnerability disclosure versus exploiting a vulnerability. Based on different motives, a rational choice or cost-benefit analyses of the possible reactions after finding a vulnerability will be discussed. Subsequently, implications for practice and future research suggestions are included.

Current research networks allow end users to build their own application-specific connections (lightpaths) and Optical Private Networks (OPNs). This requires a clear communication between the requesting application and the network. The Network Description Language (NDL) is a vocabulary designed to describe optical networks based on the Resource Description Framework (RDF). These descriptions aid applications in querying the capabilities of the network and allow them to clearly express requests to the network. This article introduces NDL and shows its current applications in optical research networks.

In the fight against the unauthorised sharing of copyright protected material, aka piracy, Dutch Internet Service Providers have been summoned by courts to block their subscribers' access to The Pirate Bay (TPB) and related sites. This paper studies the effectiveness of this approach towards online copyright enforcement, using both a consumer survey and a newly developed non-infringing technology for BitTorrent monitoring. While a small group of respondents download less from illegal sources or claim to have stopped, and a small but significant effect is found on the distribution of Dutch peers, no lasting net impact is found on the percentage of the Dutch population downloading from illegal sources.
