In the last few years, data extraction from online social networks (OSNs) has become more automated. The aim of this study was to extract all friends from MySpace profiles in order to generate a friendship graph. The graph would be analysed to investigate and apply node vulnerability metrics. This research is an extension of our previous work which concentrated on the extraction of top friends but did not investigate the graph or node vulnerability. The graph was generated from the friendship links that were extracted and placed into a repository. From the graph structure and profiles' personal details, vulnerability was calculated to find the most vulnerable node. Results were promising and provided interesting findings. Metric validation highlighted that the graph can be used to infer information that may not be present on the profile. The number of neighbours and the clustering coefficient were two main factors that affect the vulnerability of nodes.

    • "In this case the probability values are chosen values between [0] [1] which add up to 1. The attribute fullname and neighbourhood feature number_of_friends are given higher weights because fullname is a common attribute used in identity theft. "

    ABSTRACT: The increase in online social network (OSN) usage has led to personal details known as attributes being readily displayed in online profiles. This can lead to the profile owners being vulnerable to social engineering attacks. Our vulnerability model is based upon a way to quantify the vulnerability of a profile and consists of three components. The individual vulnerability is determined by the presence of values for the profile attributes which may contribute towards the composite personal vulnerability via a weight based system. The relative vulnerability indicates the contribution of collective vulnerability of the profile's friends, whereas the absolute vulnerability is the overall composite vulnerability for the profile by considering the contributions of the individual and relative vulnerabilities. In this paper we introduce a set of axioms on probability dependent effect of profile attributes and probability change for OSN profiles. The research offers a formal background for future work on estimating how attribute changes for an OSN profile influence the individual vulnerability ofthe profile and validating this composite model.

    ABSTRACT: Online social networking sites have changed the landscape of the internet. The increasing popularity of such sites leads to the aggregation of huge amount of personally identifiable and sensitive personal data online. Along with other security considerations, protection of such personal data is also coming under the responsibility of such service providers. Apart from traditional network attacks targeted on social networking sites, malicious crawlers possess greater threads to the online digital data. Today's security mechanisms to deal with malicious crawlers are not mature and having their own limitations. This paper presents a link encryption primitive to counteract with such crawlers.

    ABSTRACT: Online social network (OSN) usage has led to personal details being presented on online profiles readily. This can cause profile owners to be vulnerable to social engineering attacks. Our approach to quantifying vulnerability consists of a model with three components: individual, relative and absolute vulnerabilities. The individual vulnerability is calculated by allocating weights to profile attribute values disclosed which may contribute towards the personal vulnerability of the profile owner. The relative vulnerability is the collective vulnerability of the profiles' friends. The absolute vulnerability is the overall vulnerability for the profile which considers the individual and relative vulnerabilities. This paper extends research done on axioms based on the vulnerability model, by stating propositions to explore the effects of different operators on the profiles relative and absolute vulnerabilities. The case studies show that our approach offers a formal background for estimating how attribute and operator changes influence the individual, relative and absolute vulnerability of OSN profiles.
