Apps that use your smartphone’s microphone need to ask permission, but the motion sensors? No say-so needed. That might not sound like a big deal, but security researchers from Stanford University and defense firm Rafael have discovered a way to turn Android phone gyroscopes into crude microphones.

CSIAC Report - Smart Cities, Smart Bases and Secure Cloud Architecture for Resiliency by Design

Integration of Smart City Technologies to create Smart Bases for DoD will require due diligence with respect to the security of the data produced by Internet of Things (IOT) and Industrial Internet of Things (IIOT). This will increase more so with the rollout of 5G and increased automation "at the edge". Commercially, data will be moving to the cloud first, and then stored for process improvement analysis by end-users. As such, implementation of Secure Cloud Architectures is a must. This report provides some use cases and a description of a risk based approach to cloud data security. Clear understanding, adaptation, and implementation of a secure cloud framework will provide the military the means to make progress in becoming a smart military.
