Abstract
Mobile devices and the surrounding mobile ecosystem face many security threats. This
presentation will provide an in-depth discussion and analysis of NIST's National
Cybersecurity Center of Excellence's (NCCoE) efforts to enumerate and model these
threats, resulting in our Mobile Threat Catalogue and a mobile profile of MITRE's
ATT&CK model.
NCCoE's mobile security efforts are dedicated to solving enterprise mobile security
challenges. In talking with mobile security stakeholders, we realized there was a
need for a comprehensive catalog of threats posed to mobile devices. The resulting
Catalogue outlines a taxonomy of threats, including those faced by a mobile device
itself as well as the broader mobile ecosystem upon which the device depends. Each
Catalogue entry includes a title, exploit examples, countermeasures, and references.
The Catalogue resides on GitHub, enabling public collaboration and continuous
development.
The NCCoE and MITRE have augmented the Catalogue by building a mobile-specific
version of MITRE's ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge)
model. The mobile ATT&CK model depicts tactics and techniques used by adversaries
to gain initial access to a mobile device and then take advantage of that access to
accomplish adversarial objectives.
We will discuss how our work can benefit mobile security stakeholders, including
enabling stakeholders to depict strategies used in adversarial campaigns, identify
defensive gap areas, implement countermeasures, and determine effective security
testing strategies.
