How to Reduce the Cybersecurity Breach Contagion Effect

This article discusses a recent study titled “Do voluntary disclosures mitigate the cybersecurity beach contagion effect?” (Kelton and Pennington 2020).

This article offers practical implications of the study for financial reporting executives, boards of directors, and auditors.
