May 1st, 2023 Talk: Rethinking the Security Posture of On-Premises Enterprise Networks

Iffat Anjum, Department of Computer Science Research Assistant,  North Carolina State University

Good pedagogy should have a far-reaching influence on the students; it should support students in developing critical thinking and problem-solving skills as they enter the real world. As an educator, I always aim to engage with the students to build a lasting interest in the topic and develop their confidence to explore independently.

In this presentation, I will briefly explain how traditional network security followed the castle and moat model. I will explain the basics of this perimeter-based enterprise network security and why it’s no longer an effective security paradigm. Through discussion of fundamental ideas and attack scenarios, I hope to motivate the audiences about my Ph.D. research, “Dissolving the reliance on the perimeter to enable zero trust within on-premises enterprise networks.” My presentation will conclude with my career aspirations and philosophy as an educator in cyber security and computer science.

March 15, 2023 Talk: Coercion in Cyberspace: A Model of Extortion via Encryption

Jenny Jun, Research Fellow, Center for Security and Emerging Technology (CSET)

Coercion using cyber capabilities is often thought to be difficult due to a severe tradeoff between the need to credibly demonstrate capability versus the need to maintain a covert presence until the final payload is dropped. Jenny Jun of the Center for Security and Emerging Technology will argue that such assessments may be premature considering the logic behind the success of ransomware, which extorts victims by using encryption to deny access to critical systems or information. This discussion will provide a counterexample to the claim that cyber weapons are poor tools of coercion, and that cyber coercion depends on situational variables rather than universal features of the cyber domain itself.

Feb 15, 2023 Talk: Assessing the Cyber-attack Surface of Local Infrastructures

Dr. Ido Sivan-Sevilla, Assistant Professor, University of Maryland College of Information Studies


Access to social goods such as information, education, health, news, and utilities is now mediated through private & public socio-technical systems. Those systems advance certain goods, but at the same time risk our privacy and are vulnerable to alarming security compromises. Public policy systems have been trying to respond, struggling to create meaningful changes. Their struggle is not only due to political and bureaucratic reasons [1-5], but also because of the inability of public officials to evaluate and scrutinize the technologies they govern.

My talk discusses how we can use ‘civic technologies’ to collect & analyze publicly available data on the operation of central socio-technical systems in society. I will demonstrate that through a project that aims to assess potential vulnerabilities in US’ local infrastructures – a usually under-funded cybersecurity space [6]. This is a collaboration with Charles Harry & Mark McDermott in which we apply a self-developed application to scan publicly facing devices of government networks, hospitals, K-12 schools, and wastewater infrastructures across local counties in the US. Through interaction with commercial port scan services – Censys & Shodan – the tool finds open ports, services, and CVEs that can be exploited in sensitive public networks. Then, we aim to rank the severity of open services based on the pace of their exploitation in the wild, evaluated through adapted honeypot farms. The project produces routine attack surface reports grouped by organizations within a given geographic jurisdiction and compiled into a first-of-its-kind integrated picture of cyber risks across local infrastructures. This is work-in-progress, and preliminary results on Maryland, Delaware, and Virginia’s attack surfaces will be presented.


May 13, 2021 Talk: Reflecting on Sociotechnical Perspectives, Gaps, and Opportunities for Medical Device Security: A Fireside Chat

Today, it would be difficult to find medical device technology that does not critically depend on computer software. Network connectivity and wireless communication has transformed the delivery of patient care. The technology often enables patients to lead more normal and healthy lives. However, medical devices that rely on software (e.g., drug infusion pumps, linear accelerators, pacemakers) also inherit the pesky cybersecurity risks endemic to computing. What’s special about medical devices and cybersecurity? What’s hype and what’s real? What can history teach us? How are international standards bodies and regulatory cybersecurity requirements changing the global manufacture of medical devices? This talk will provide a glimpse into the risks, benefits, and regulatory issues for medical device cybersecurity and innovation of trustworthy medical device software. This talk will also explore current and potential uses for sociotechnical approaches to medical device security, including identifying human-domain security challenges, and how these uses complement current practices.

April 21, 2021 Talk: A Playbook for Effective Corporate Communication After Cybersecurity Incidents

Speaker: Dr. Jason Nurse

A cybersecurity incident can cripple an organization, particularly because of the related risk of significant reputational damage. As the likelihood of falling victim to a cyberattack has increased, so too has the importance of understanding what effective corporate communications and public relations look like after an attack. Key questions that need immediate answers include: What messages should be communicated to customers? How should correspondence be released? Who should speak to the media and public? In this talk, Dr. Nurse presents recent research into a playbook to support companies in deciding how to answer these questions and more. This work is grounded in real-world case studies and academic insights and has been validated and refined through interviews with senior security and crisis response industry professionals.

March 11, 2021 Talk: Trusting Infrastructure: The Emergence of Computer Security Incident Response, 1989-2005

Speaker: Dr. Rebecca Slayton

Historians have tended to analyze maintenance as an intrinsically local activity, something very unlike the development of large technological systems. This article challenges this historiographic dichotomy by examining efforts to construct a global infrastructure for maintaining computer security. In the mid-1990s, as the internet rapidly grew, commercialized and internationalized, a small community of computer security incident responders sought to scale up their system of coordination, which had been based on interpersonal trust, by developing trusted infrastructure that could facilitate the worldwide coordination of incident response work. This entailed developing not only professional standards, but also institutions for embodying and maintaining those standards in working infrastructure. While some elements of this infrastructure became truly global, others remained regionally bounded. We argue that this boundedness resulted not from the intrinsically local nature of maintenance, but from the historical process of infrastructure development, which was shaped by regionally based trust networks, institutions, and needs.

Feb. 11, 2021 Talk: How managed security and technology are redefining how insurance operates in society

Speaker. Dr. Shauhin Talesh

Existing research suggests an increasing prevalence and reliance on data and technology across significant segments of society. This often takes the form of datafication, information capitalism, and involves data brokers. However, there has been less focus on the processes and mechanisms through which data and technology influence particular industries. Using cybersecurity as an area of focus, this study explores how data and technology influence how the insurance industry operates. We focus on cyber insurance, an area where insurers historically have lacked large actuarial data and have faced challenges on how to manage this risk. Drawing from interviews with over sixty persons in the insurance industry, analysis of big data, insurance applications, and industry materials, we find that technology is the mechanism through which insurers regulate. In addition to risk management, we explore how technology and managed security influence the underwriting, pricing, advertising, and purchase of insurance. We explore the implications of the rise of insur-tech for the insurance industry, cybersecurity, and society.

headshot of Shauhin TaleshProfessor Talesh is an interdisciplinary scholar whose work spans law, sociology, and political science. His research interests include the empirical study of law and business organizations, dispute resolution, consumer protection, insurance, and the relationship between law and social inequality. Professor Talesh’s most recent empirical study addresses the intersection between organizations, risk, and consumer protection laws, focusing on private organizations’ responses to and constructions of laws designed to regulate them, consumers’ mobilization of their legal rights and the legal cultures of private organizations. Professor Talesh’s scholarship has appeared in multiple law and peer-reviewed social science journals including Law and Society Review and has won multiple awards in Sociology, Political Science and Law & Society.

Dec. 11, 2020 Talk: The simulation of scandal: Hack-and-leak operations, the Gulf States, and U.S. politics

Speaker: Dr. James Shires

Four hack-and-leak operations in U.S. politics between 2016 and 2019, publicly attributed to the United Arab Emirates (UAE), Qatar, and Saudi Arabia, should be seen as the “simulation of scandal” — deliberate attempts to direct moral judgment against their target. Although “hacking” tools enable easy access to secret information, they are a double-edged sword, as their discovery means the scandal becomes about the hack itself, not about the hacked information. There are wider consequences for cyber competition in situations of constraint where both sides are strategic partners, as in the case of the United States and its allies in the Persian Gulf.

Nov. 19, 2020 Talk: Cybersecurity and local government: Findings from a nationwide survey

Speakers: Dr. Donald Norris & Laura Mateczun

This talk discussed data and results from the first nationwide survey of cybersecurity among local or grassroots governments in the United States and examined how these governments manage this important function. As we have shown elsewhere, cybersecurity among local governments is increasingly important because these governments are under constant or nearly constant cyberattack. Due to the frequency of cyberattacks, as well as the probability that at least some attacks will succeed and cause damage to local government information systems, these governments have a great responsibility to protect their information assets. This, in turn, requires these governments to manage cybersecurity effectively, something our data show is large
ly absent at the American grassroots. That is, on average, local governments fail to manage cybersecurity well. After discussing our findings, we conclude and make recommendations for ways of improving local government cybersecurity management.
