12. Art Crime Does not pay: Multiplexed Social Network Analysis in Cultural Heritage Trafficking Forensics.

Author

Salonen, Jarno and Guarino, Alessandro

Abstract

Nowadays, crimes connected to cultural heritage can feature as a staple for organised crime networks and act as financial enablers for international conflicts, including terrorism organisations and even inter-state conflicts, in several ways. Goods of cultural significance include a range of valuable objects related to human cultures, like works of art, historical artefacts, and other antiques, but also forgeries based on such objects. These crimes are almost always transnational, for instance, involving theft or looting in one country and goods moved across borders to be sold. This article presents an intelligence methodology based on Social Network Analysis (SNA) techniques that can support law enforcement agencies (LEAs) in their daily struggle against criminals that also pose a threat to national security. The methodology proposed is based on the building of a blended, multiplexed social network graph, deriving from the fusion of a diverse set of data sources, both in the open-source domain (OSINT) and in the classified domain. We will present data collection methods, correlation between sources, possible ways to generate blended links between individuals that retain information from different sources, and SNA techniques applied to intelligence and investigations. The article provides an answer to the following research questions: how we can detect and identify criminal activities and networks related to cultural goods crimes, how we can assist LEAs in countering illicit trafficking, and how we can ensure that art crime does not pay.

Abstract

The ongoing need for societal and industrial digital transformation requires rapidly expanding networks of interconnected organizations and dictates an increasing role for cybersecurity in information sharing. A typical setup consists of multiple stakeholders working closely together and needing efficient channels for sharing relevant information in a secure manner. This is especially prevalent with complex modern supply chains and critical information infrastructures. They often comprise of numerous co-operating organizations, people and in some cases smart devices having different levels of access to a variety of information. Granular access control plays a vital role when distributing information efficiently between stakeholders without revealing sensitive pieces of data to unwanted third parties. This article presents a novel framework for enabling fine-grained access control to share information efficiently and securely in these situations. Our motivation and use case for the framework originates from the secure sharing of cyber incident information in the maritime logistics industry. We present a novel solution to this problem by developing an information sharing platform and a meta-model, demonstrated using an implementation with structured JSON data formats, while supporting previously researched attribute-based encryption schemes. The proposed framework provides a broader context to the fine-grained data access control challenge in addition to the technical implementation.

Abstract

The current shortage of cybersecurity professionals is about 2 million people worldwide, and in Europe the industry is seeking for about 350 000 skilled professionals. There is also an enormous need for dedicated cybersecurity training courses for existing professionals who wish to acquire completely new skills or maintain their current ones. Due to the lack of new skilled workforce, the current cybersecurity personnel are overworked in their work. In order not to waste the valuable time of cybersecurity professionals with unnecessary training, cyber exercises should be well prepared. This article is based on research conducted in a European collaborative project and more specifically, a cyber exercise organised in early 2022. The purpose of our research was to conduct a preliminary assessment of the participants to learn about their skills and expectations before the cyber exercise. This assessment was used for fine-tuning the exercise. To achieve this, we identified common trends in the participants’ interests during the cyber exercise. The preliminary assessment was carried out as a web survey. The responses were cross tabulated to find meaningful indicators related to skills and interests of the participant group. We identified the most and least preferred knowledge areas for both the industry and public sector participants. Our findings show that the most interesting knowledge areas of all respondents were primarily technical in nature (Data Security, Connection Security, System Security), but Organisational Security was also reported. The least interesting knowledge areas were mostly non-technical in nature (Human Security, Organisational Security, Societal Security) but also Component Security was reported. We also enquired about the preferred team size. The majority of the respondents preferred a team size of three to four persons. The preferred single session duration was 46–60 minutes. The results help cybersecurity professionals to match their knowledge needs with the existing cybersecurity proposition and to determine the right and most beneficial training for them. The results also assist the providers of cyber training and other exercises to describe the targeted development of specific cybersecurity and other knowhow in a coherent, standard-like, way.
