"We believe our paper adds to the important body of cybersecurity literature that explores the roles of government and business, particularly corporate directors, in the governance of data security."
"Using a large sample of U.S. firms over the period 2007-2017, we find that when cybersecurity risk is higher, firms hold more cash."
"These attacks are unknown to the human eye due to malicious intent to harm any underlying infrastructure. So, to overcome the problems and make a flexible solution, we propose a framework where machine learning algorithms are applied to find relevant features from the existing dataset."
"... there is a risk that the EU’s Network and Information Systems Directive (‘NIS Directive’) might lead to only incremental improvements in the cybersecurity of Europe’s critical infrastructure and digital services, while generating substantial compliance activity, aimed at placating regulators and reassuring the general public."
"We apply Weick’s (1995) sensemaking framework to examine four foundational tensions of cyber-resilience: a definitional tension, an environmental tension, an internal tension, and a regulatory tension. We then document how these tensions are embedded in cyber-resilience practices at the preparatory, response and adaptive stages. We rely on qualitative data from a sample of 58 cybersecurity professionals in the financial sector..."
"We conclude that the purchase of cyber insurance is indicative of an overall higher risk profile, but that having that insurance after experiencing a breach and formalizing cyber risk oversight within the audit committee reduces auditors’ perceptions of risk."
"Likelihood and impact are variables that are stressed when characterizing risks, evolving as an organization increases scalability and network infrastructure. Effective security risk management preparation relies severely on initiative-taking and adversarial mindsets."
"We show how to use Schelling’s focal points together with Kahneman & Tversky’s reference points and related concepts from behavioural economics to complement technical innovations and improve threat detection and deterrence."
"Cyber attacks can impair banks operations and precipitate bank runs. When digital infrastructure is shared, banks defend themselves by investing in cybersecurity but can free-ride on the security measures of others. Ex ante free-riding by banks interacts with the ex post coordination frictions underpinning bank runs."
" Through this analysis we are able to address the question that, to the best of our knowledge, no other study has investigated in the context of cyber risk: is model risk present in cyber risk data, and how does is it translate into premium mispricing?"
