* Define a new small UAV cyber risk
assessment tool (assuming none
exists).
* Establish the objectives a hardware-inthe-loop simulation of a small UAV

should meet to best bring awareness
to potential vulnerabilities.
The hypothesis of this research is that
no cyber risk assessment tool currently
exists and no similar domain assessment accurately portrays the risk of
small UAVs to its operators/owners. If

sight by regulators. Most organizations
do incorporate some sort of cyber risk
framework to manage risks, but these
frameworks are reliant on lackluster risk
assessments for small UAVs.
In some sense, manufacturers currently control small UAVs' cyber security
standards by setting their own levels of
protection, which may not be acceptable
with consumers. Organizations have little measurement or insight into the risks
accepted with purchasing and operating
these vehicles as there is no formal
method of comparison, as may be seen
with other vehicle safety. Additionally,
while manufacturers may have a vested
interest in protecting their devices from
outside compromise, the cost of cyber security efforts and overhead of components and software compete with financial and physical constraints.
This research defines a new cyber risk
assessment for small UAVs using the lessons learned from assessments in related systems and then tests and analyzes this new scoring system by
presenting case studies that represent
the breadth of models and mission scenarios for small UAVs. The research objectives of this work are as follows:
* Assess whether any cyber or physical
risk assessments of similar domains
accurately quantify the cyber risk of
small UAVs.
* Determine the success criteria a small
UAV cyber risk assessment should
