Abstract: 

This applied research talk will discuss the privacy threat modeling gap, challenges and opportunities of privacy threat modeling in practice, and a new qualitative threat model currently under development. In privacy risk management, there are well-respected methods for modeling vulnerabilities and consequences (or harms), but there is no commonly used model nor lexicon for characterizing privacy threats. We will discuss the gap in privacy risk modeling, how privacy threat-informed defense could better protect systems from privacy harms, and a working definition for a “privacy attack.” Then we will present a draft qualitative threat model – the Privacy Threat Taxonomy – developed to fill this gap in privacy risk modeling. This model was generated iteratively and collaboratively using a dataset of almost 150 non-breach privacy events, which includes directed, accidental, and passive attacks on systems. We will also discuss how practitioners can incorporate a threat model into their privacy risk management program.
