Herding Vulnerable Cats: A Statistical Approach to Disentangle Joint Responsibility for Web Security in Shared Hosting

Hosting providers play a key role in fighting web compromise, but their ability to prevent abuse is constrained by the security practices of their own customers. {\em Shared} hosting, offers a unique perspective since customers operate under restricted privileges and providers retain more control over configurations. We present the first empirical analysis of the distribution of web security features and software patching practices in shared hosting providers, the influence of providers on these security practices, and their impact on web compromise rates. We construct provider-level features on the global market for shared hosting -- containing 1,259 providers -- by gathering indicators from 442,684 domains. Exploratory factor analysis of 15 indicators identifies four main latent factors that capture security efforts: content security, webmaster security, web infrastructure security and web application security. We confirm, via a fixed-effect regression model, that providers exert significant influence over the latter two factors, which are both related to the software stack in their hosting environment. Finally, by means of GLM regression analysis of these factors on phishing and malware abuse, we show that the four security and software patching factors explain between 10\% and 19\% of the variance in abuse at providers, after controlling for size. For web-application security for instance, we found that when a provider moves from the bottom 10\% to the best-performing 10\%, it would experience 4 times fewer phishing incidents. We show that providers have influence over patch levels--even higher in the stack, where CMSes can run as client-side software--and that this influence is tied to a substantial reduction in abuse levels

Exploring Cybertechnology Standards Through Bibliometrics: Case of National Institute of Standards and Technology

Cyber security is one of the topics that gain importance today. It is necessary to determine the basic components, basic dynamics, and main actors of the Cyber security issue, which is obvious that it will have an impact in many areas from social, social, economic, environmental, and political aspects, as a hot research topic. When the subject literature is examined, it has become a trend-forming research subject followed by institutions and organizations that produce R&D policy, starting from the level of governments. In this study, cybersecurity research is examined in the context of 5 basic cyber security functions specified in the cyber security standard (CSF) defined by the National Institute of Standards and Technology (NIST). It is aimed to determine the research topics emerging in the international literature, to identify the most productive countries, to determine the rankings created by these countries according to their functions, to determine the research clusters and research focuses. In the study, several quantitative methods were used, especially scientometrics, social network analysis (SNA) line theory and structural hole analysis. Statistical tests (Log-Likelihood Ratio) were used to reveal the prominent areas, and the text mining method was also used. we first defined a workflow according to the “Identify”, “Protect”, “Detect”, “Respond” and “Recover” setups, and conducted an online search on the Web of Science (WoS) to access the information on the publications on the relevant topics It is seen that actors, institutions and research create different densities according to various geographical regions in the 5 functions defined within the framework of cybersecurity. It is possible to say that infiltration detection, the internet of things and the concept of artificial intelligence are among the other prominent research focuses, although it is seen that smart grids are among the most prominent research topics. In the first clustering analysis we performed, we can say that 17 clusters are formed, especially when we look under the definition function. The largest of these clusters has 32 data points, so-called decision making models

An analysis of cybersecurity culture in an organisation managing Critical Infrastructure

The 4th industrial revolution (4IR) is transforming the way businesses operate, making them more efficient and data-driven while also increasing the threat-landscape brought on by the convergence of technologies and increasingly so for organisations managing critical infrastructure. Environments that traditionally operated entirely independent of networks and the internet are now connecting in ways that are exposing critical infrastructure to a new level of cyber-risks that now need to be managed. Due to the stable nature of technologies and knowledge in traditional industrial environments, there is a misalignment of skills to emerging technology trends. Globally cyber-crime attacks are on the rise with Cisco reporting in 2018 that 31% of all respondents had seen a cyber-attack in their operational environment[1]. With up to 67% of breaches reported in the Willis Towers report due to employee negligence [2], the importance of cybersecurity culture is no longer in question in organisations managing critical infrastructure. Developing an understanding of the drivers for behaviours, attitudes and beliefs related to cybersecurity and aligning these to an organisations risk appetite and tolerance is crucial to managing cyber-risk. There is a very divergent understanding of cyber-risk in the engineering environment. This study endeavours to investigate employee perceptions, attitudes and values associated with cybersecurity and how these potentially affects their behaviour and ultimately the risk to the plant or organisation. Most traditional culture questionnaires focus on information security with observations focussing more on social engineering, email hygiene and physical controls. This cybersecurity culture study was conducted to gain insight into people's beliefs, attitudes and behaviours related to cybersecurity encompassing people, process and technology focussing on the operational technology environment in Eskom1. Both technical (Engineering and IT) and nontechnical (business support staff) staff were questionnaireed. The questionnaire was categorised into four sections dealing with cybersecurity culture as they relate to individuals, processes and technology, leadership and the organisation at large. The results from the analysis, revealed that collaboration, information sharing, reporting of vulnerabilities, high dependence and trust in technology, leadership commitment, vigilance, compliance, unclear processes and lack of understanding around cybersecurity all contribute to the current levels of cybersecurity culture. Insights from this study will generate recommendations that will form part of a cybersecurity culture transformation journey

Internet research and the implications for ethical research practice

The Internet has extended the opportunity for researchers to investigate human actions and interactions. This study aims to critically examine the various ways that ethical considerations associated with Internet-Mediated Research (IMR) are constructed as a social reality by Australian Human Research Ethics Committee (HREC) and the implications for research practice. This project builds on research undertaken in the United States by Buchannan and Ess (2009) which discussed US Institutional Review Boards (IRBs) and the state of Internet research ethics. An explanatory sequential mixed design, consisting of two distinct phases was conducted (Creswell & Plano Clark, 2003). Quantitative data was collected and analysed in the first phase (Study 1) via an online survey of Australian Human Research Ethics Committee members from March to April 2016. Semi-structured interviews (n=3) were then conducted with Chairpersons of Australian Human Research Ethics Committees (Study 2) and analysed to further explain and clarify results found in the first data collection phase. Results of current processes and practices of Australian HRECs obtained in Study 1 were found to be similar to those reported by US IRBs and suggested that ethical review boards may be ill-equipped and ill-trained to navigate the review of IMR protocols. However, the addition of a qualitative overlay via the Australian HREC Chairperson’s interviews in Study 2 provided additional detail that suggested that reviewing IMR protocols is more complex than previously understood. Thematic analysis of the interview data identified that the ethical review of IMR protocols is thoroughly undertaken via a principle-based process as it is not viewed as being different to any other research method or tool. Additionally, ethical responsibility in this space is shared amongst the HREC, researchers, and participants themselves

SoK: Design, Vulnerabilities and Defense of Cryptocurrency Wallets

The rapid growth of decentralized digital currencies, enabled by blockchain technology, has ushered in a new era of peer-to-peer transactions, revolutionizing the global economy. Cryptocurrency wallets, serving as crucial endpoints for these transactions, have become increasingly prevalent. However, the escalating value and usage of these wallets also expose them to significant security risks and challenges. This research aims to comprehensively explore the security aspects of cryptocurrency wallets. It provides a taxonomy of wallet types, analyzes their design and implementation, identifies common vulnerabilities and attacks, and discusses defense mechanisms and mitigation strategies. The taxonomy covers custodial, non-custodial, hot, and cold wallets, highlighting their unique characteristics and associated security considerations. The security analysis scrutinizes the theoretical and practical aspects of wallet design, while assessing the efficacy of existing security measures and protocols. Notable wallet attacks, such as Binance, Mt. Gox are examined to understand their causes and consequences. Furthermore, the paper surveys defense mechanisms, transaction monitoring, evaluating their effectiveness in mitigating threats
