• A Feature-Driven Analysis of Global Cybersecurity Regulations and their Impact on Safeguarding Data Value

  Journal of Data and Information Quality · 2026-03-27

  articleSenior author

  An important goal of Chief Data Officers (CDOs) and data quality efforts is to increase the value of an organization's data. But that increased value makes the data an even more desirable target for cyberattacks, which have become more frequent, sophisticated, and impactful. In addition to the efforts that individual companies have made, the governments worldwide are responding by introducing or proposing new cybersecurity regulations to help protect that data, making security an important aspect of data quality. This study offers a novel perspective on the evolving global cybersecurity regulatory environment. Drawing on a comprehensive comparative analysis of nearly 200 regulatory frameworks from a wide array of international and national jurisdictions, the research identifies a core group of regulatory features that are systematically organized into five principal thematic categories. In particular, this research employs an integrated classification schema and a multidimensional taxonomy to facilitate more precise navigation of the complex regulatory landscape. Using a structured qualitative synthesis approach combining elements of review and cross-jurisdictional mapping, the analysis highlights notable disparities in regional regulatory focus, with Data Privacy, Incident Reporting, and Security by Design standing out as the most recurrent regulatory priorities. A significant outcome of the study is the identification of varying synergy levels between regulatory features, with high integration observed in Data Privacy and Cross-Border Data Transfer, medium synergy in areas such as Incident Reporting and Risk Management, and low synergy between Security by Design and Emerging Technologies. Therefore, by examining how various regulatory features align—or fail to align—across jurisdictions, the study provides critical insights for legislators, regulators, and data quality leaders and researchers. The paper concludes with targeted recommendations to support more consistent, adaptive, and future-resilient cybersecurity governance worldwide to further improve data quality.

• Analyzing and Categorizing Emerging Cybersecurity Regulations

  ACM Computing Surveys · 2025-08-02 · 2 citations

  reviewOpen accessSenior author

  As cyber-attacks become more frequent, sophisticated, and impactful, governments worldwide are responding by introducing or proposing new cybersecurity regulations. This article examines over 170 recent regulations and trends in cybersecurity across various regions, including the United States, Europe, and beyond. It identifies 17 key features in many of these regulations, which we have grouped into 5 categories, analyzes observed patterns, and proposes areas for improvement. This article's primary objective is to significantly contribute to the cybersecurity compliance domain by helping researchers understand the structure of these regulations and helping organizations to assess and mitigate their cyber risk within an increasingly complex and regulated cybersecurity environment. Our findings provide valuable direction to those trying to navigate the flood of new cybersecurity regulations and the governments enacting new cybersecurity regulations.

• Weathering the storm: examining how organisations navigate the sea of cybersecurity regulations

  European Journal of Information Systems · 2024-04-26 · 12 citations

  articleOpen accessSenior author

  Governments around the world routinely regulate the activities of private enterprises to guide the behaviour of individuals and organisations towards acceptable norms. This holds true in a cybersecurity context. However, practitioners report that cybersecurity regulations are often out of date and compliance is confusing, expensive, and time consuming. As a result, organisational leaders are often uncertain about the practicalities of adopting and implementing the various rules, which can lead to trickle-down effects on the robustness of lower-level cybersecurity controls and compliance activities. In this research, we aim to clarify how cybersecurity regulations are operationalised in organisations, as well as reveal the compliance and performance consequences of cybersecurity regulations. To do so, we interviewed 22 senior leaders with expertise in cybersecurity regulations. Our analysis reveals 7 distinct themes (i.e., concept groupings) that are ordered within four phases (i.e., temporal stages), which we use to create the Institutional Cybersecurity Regulations Model (ICRM). The results provide a holistic view of the cybersecurity regulations process in organisations that can serve to clarify current theory relationships and inform future research. As well, the ICRM can provide a practical roadmap for managers to navigate regulatory cybersecurity challenges in their own companies.

• The Importance of Board Member Actions for Cybersecurity Governance and Risk Management

  MIS Quarterly Executive · 2023-01-01 · 4 citations

  article

  Boards of directors are increasingly responsible for providing guidance and oversight on cybersecurity risk, yet are often unequipped to do so. This critically important mandate introduces novel challenges to what is already a complex governance environment. Drawing on in-depth interviews with board members and executives, we describe four core cybersecurity challenges that boards encounter and provide 10 recommended actions they can take in response. These actions enable boards to optimize their ability to provide meaningful, effective governance to address cybersecurity risk.

• Decoding Cyber Incident Reporting Requirements: A Cross-Regulatory Examination

  2023-08-14 · 2 citations

  articleSenior author

  With the rise of digital technologies, cyber incidents have become increasingly common and complex, presenting significant dangers to individuals and organizations. In response, various governments and regulatory bodies have established incident reporting regulations for organizations to abide by. However, the efficiency of these regulations in managing cyber incidents is still a matter of discussion. This paper assesses recent cyber incident reporting laws and evaluates their effectiveness in terms of factors such as timing rules and the level of detail in defining cyber incidents and reporting procedures. Finally, this paper suggests improvements to regulatory requirements to better address the reporting of cyber incidents in today’s rapidly changing regulatory landscape.

• The evolution of global cybersecurity norms in the digital age: A longitudinal study of the cybersecurity norm development process

  Figshare · 2023-01-01

  datasetOpen accessSenior author

  Developing cybersecurity norms and global normative cybersecurity behaviors play an increasingly critical role in global cybersecurity governance. This paper takes a longitudinal approach to analyze cybersecurity norms development activities during the period 1997–2020. A total of 206 individual cases were collected, and 233 individual cybersecurity norms were identified and compiled into 25 subject categories. Categorizing the norm subjects alongside the frequency of cases and norms identified each year allowed for a longitudinal view of cyber norm activities and the evolution in developments over these years. This examination enables us to categorize cybersecurity norms, including their dynamic focus and evolution patterns. By studying those viewed as “successful,” we gain guidance regarding the construction of global cybersecurity governance in the digital age.

• A Systematic Analysis of the Capital One Data Breach: Critical Lessons Learned

  ACM Transactions on Privacy and Security · 2022-07-07 · 56 citations

  articleOpen accessSenior author

  The 2019 Capital One data breach was one of the largest data breaches impacting the privacy and security of personal information of over a 100 million individuals. In most reports about a cyberattack, you will often hear that it succeeded because a single employee clicked on a link in a phishing email or forgot to patch some software, making it seem like an isolated, one-off, trivial problem involving maybe one person, committing a mistake or being negligent. But that is usually not the complete story. By ignoring the related managerial and organizational failures, you are leaving in place the conditions for the next breach. Using our Cybersafety analysis methodology, we identified control failures spanning control levels, going from rather technical issues up to top management, the Board of Directors, and Government regulators. In this analysis, we reconstruct the Capital One hierarchical cyber safety control structure, identify what parts failed and why, and provide recommendations for improvements. This work demonstrates how to discover the true causes of security failures in complex information systems and derive systematic cybersecurity improvements that likely apply to many other organizations. It also provides an approach that individuals can use to evaluate and better secure their organizations.
