Social Engineering as an Approach for Probing Organizations to Improve IT Security

From the article: This paper describes the external IT security analysis of an international corporate organization, containing a technical and a social perspective, resulting in a proposed repeatable approach and lessons learned for applying this approach. Part of the security analysis was the utilization of a social engineering experiment, as this could be used to discover employee related risks. This approach was based on multiple signals that indicated a low IT security awareness level among employees as well as the results of a preliminary technical analysis. To carry out the social engineering experiment, two techniques were used. The first technique was to send phishing emails to both the system administrators and other employees of the company. The second technique comprised the infiltration of the office itself to test the physical security, after which two probes were left behind. The social engineering experiment proved that general IT security awareness among employees was very low. The results allowed the research team to infiltrate the network and have the possibility to disable or hamper crucial processes. Social engineering experiments can play an important role in conducting security analyses, by showing security vulnerabilities and raising awareness within a company. Therefore, further research should focus on the standardization of social engineering experiments to be used in security analyses and further development of the approach itself. This paper provides a detailed description of the used methods and the reasoning behind them as a stepping stone for future research on this subject. van Liempd, D., Sjouw, A., Smakman, M., & Smit, K.

Displacement-based earthquake loss assessment for an earthquake scenario in Istanbul

DBELA is a Displacement-Based Earthquake Loss Assessment methodology for urban areas which relates the displacement capacity of the building stock to the displacement demand from earthquake scenarios. The building stock is modeled as a random population of building classes with varying geometrical and material properties. The period of vibration of each building in the random population is calculated using a simplified equation based on the height of the building and building type, whilst the displacement capacity at different limit states is predicted using simple equations which are a function of the randomly simulated geometrical and material properties. The displacement capacity of each building is then compared to the displacement demand obtained, from an over-damped displacement spectrum, using its period of vibration; the proportion of buildings which exceed each damage state can thus be estimated. DBELA has been calibrated to the Turkish building stock following the collection of a large database of structural characteristics of buildings from the northern Marmara region. The probabilistic distributions for each of the structural characteristics (e.g. story height, steel properties etc.) have been defined using the aforementioned database. The methodology has then been applied to predict preliminary damage distributions and social losses for the Istanbul Metropolitan Municipality for a Mw 7.5 scenario earthquake.

The social visuality of distant suffering

How to fulfil social needs of older people

Social needs are important basic human needs; when not satisfied, loneliness and social isolation can occur and subsequently sickness or even premature death. For older people social needs can be more difficult to satisfy be­cause of the loss of resources such as health and mobility. Interventions for older people to satisfy social needs are often not evaluated and when evaluated are not proven successful. Technological interventions can be successful, but the relationship between technology and social wellbeing is complex and more research in this area is needed. The aim of this research is to uncover design opportunities for technological interventions to fulfil social needs of older people. Context-mapping sessions are a way to gain more insight into the social needs of older people and to involve them in the design of interventions to fulfil social needs. Participants of the context-mapping sessions were older people and social workers working with older people. Four sessions with a total of 20 participants were held to generate ideas for interventions to satisfy social needs. The results are transcripts from the discussion parts of the context-mapping sessions and collages the participants cre­ated. The transcripts were independently analysed and inductive codes were attached to quotations in the transcripts that are relevant to the research question and subsequently thematic analysis took place. Collages made by the participants were independently ana­lysed by the researchers and after discussion consensus was reached about important themes. The following three main themes emerged: ‘connectedness’, ‘independence’ and ‘meaningfulness’. Technology was not identified as a separate theme, but was addressed in relation to the above mentioned themes. Staying active in a meaningful way, for example by engaging in volunteer work, may fulfil the three needs of being connected, independent and meaningful. In addition, interventions can also focus on the need to be and remain independent and to deal with becoming more dependent. The older people in our study have an ambivalent attitude towards technology, which needs to be taken into account when designing an intervention. We conclude this paper by making recommendations for possible technological interventions to fulfil social needs.

What is the social in social media?

The use of the word “social” in the context of information technology goes back to the very beginnings of cybernetics. It later pops up in the 1980s context of “groupware.” The recent materialist school of Friedrich Kittler and others dismissed the use of the word “social” as irrelevant fluff – what computers do is calculate, they do not interfere in human relations. Holistic hippies, on the other hand, have ignored this cynical machine knowledge and have advanced a positive, humanistic view that emphasizes computers as tools for personal liberation. This individualistic emphasis on interface design, usability, and so on was initially matched with an interest in the community aspect of computer networking. Before the “dot-com” venture capitalist takeover of the field in the second half of the 1990s, progressive computing was primarily seen as a tool for collaboration among people.
