Het succes van social engineering

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Awareness, E-mail phishing, Social Engineering, Telefoonfraude
Auteurs Jan-Willem Bullée, Lorena Montoya, Marianne Junger e.a.
SamenvattingAuteursinformatie

    Social engineering is the usage of social manipulation and psychological tricks to make the targets assist offenders in their attack. This paper aimed to discuss the success of social engineering attacks and interventions in an organisational setting. Three kinds of social engineering experiments were discussed, each using a different modality (i.e. face-to-face (f2f), email and telephone). In each experiment, the targets (i.e. participants) were persuaded to perform actions that contribute to their victimisation.
    A portion of the participants in both the f2f and telephone experiment received an intervention to reduce victimisation. The conclusion is that awareness raising about dangers, characteristics and countermeasures related to social engineering proved to have a significant positive effect on protecting the target. The results of these experiments allow practitioners to focus awareness campaigns to maximise their effectiveness.

Persoonlijkheidskenmerken van e-fraudeslachtoffers

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Online fraud, Big Five personality traits, Phishing, online marketplace fraud, cybercrime prevention
Auteurs Jildau Borwell, Jurjen Jansen en Wouter Stol
SamenvattingAuteursinformatie

    With the digitization of society, perpetrators gained new tools to commit crimes. Online fraud, also referred to as e-fraud, is one of the most common types of cybercrime. The present study focusses on two types of e-fraud: phishing and online consumer fraud. Although e-fraud always contains a digital component, the human is the weakest link in such crimes. Perpetrators deceive their victims to acquire sensitive data or to conclude a fraudulent sale, which makes victims unwillingly participate in the offence. However, not every person adheres to such fraudulent schemes. This raises the question what makes some people comply with these schemes and thus become a victim of cybercrime, while others do not. In this study, the differences between personality traits of e-fraud victims and the Dutch population were investigated. Personality traits influence the way people process information and react to situations, which also applies when people are confronted with e-fraud. Data were collected through an online survey, in which 224 e-fraud victims participated. The outcomes of the survey were compared with norm groups representative for the Dutch population. E-fraud victims, compared to the Dutch population, scored higher on extraversion, altruism and conscientiousness, and lower on neuroticism. Based on the findings, recommendations have been made for the development of targeted preventive measures against e-fraud.

De twitterende wijkagent en het veiligheidsgevoel van de burger

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2016
Trefwoorden Twitter, police, safety perceptions, communication, social media
Auteurs Imke Smulders, Wilbert Spooren en Emile Kolthoff
SamenvattingAuteursinformatie

    This article reports on a conceptual model that provides insight into the relationship between Twitter use by community policing officers and citizens’ safety perceptions. The model has been tested using data from a relatively large-scale survey study and these results are supporting the model. Furthermore, a small impact of Twitter use has been found on feelings of safety and judgments about the police. To confirm these findings, further research on a larger scale is necessary. To find out more about the exact positive and negative effects of Twitter use by community policing officers, a more experimental design is required.

Positieve veiligheid. Een theoretische analyse van een omstreden begrip

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2015
Trefwoorden Positieve veiligheid, geschiedenis, begripsanalyse, kritiek, ethiek
Auteurs Gerben Bakker
SamenvattingAuteursinformatie

    The concept of positive security appears more and more often in academic and public discussions. It presents a normative agenda for a non-repressive approach of security. In the article, it is claimed that the concept and its implications lack fundamental clarity. First of all, it is illustrated that the meaning of positive security primarily develops on the renouncement of negative security. Second, a historical comparison between the discipline of international relations and criminology discloses that different meanings have been assigned to positive security that seem at times at odds with each other. These frictions substantiate the view that it is problematic to accept positive security as an unequivocal recipe for change. Finally, the consequences of the disseminated structure of meaning are discussed in relation to the ambition of reform that positive security represents. For example, advocates of positive security do not seem eager to commit themselves to very clear normative views. This makes it difficult to really pin down what the suggested changes underlying positive security, are truly implying. Moreover, positive security invites us to extend the horizon of security politics to include various kinds of positive needs and values. But doesn’t this take us back to the initial criticism that the reach of the security concept has extended too much, covering virtually every aspect of life?
