  Bluetooth Low Energy (BLE) has become the primary transmission media due to
its extremely low energy consumption, good network scope, and data transfer
speed for the Internet of Things (IoT) and smart wearable devices. With the
exponential boom of the Internet of Things (IoT) and the Bluetooth Low Energy
(BLE) connection protocol, a requirement to discover defensive techniques to
protect it with practical security analysis. Unfortunately, IoT-BLE is at risk
of spoofing assaults where an attacker can pose as a gadget and provide its
users a harmful information. Furthermore, due to the simplified strategy of
this protocol, there were many security and privacy vulnerabilities. Justifying
this quantitative security analysis with STRIDE Methodology change to create a
framework to deal with protection issues for the IoT-BLE sensors. Therefore,
providing probable attack scenarios for various exposures in this analysis, and
offer mitigating strategies. In light of this authors performed STRIDE threat
modeling to understand the attack surface for smart wearable devices supporting
BLE. The study evaluates different exploitation scenarios Denial of Service
(DoS), Elevation of privilege, Information disclosure, spoofing, Tampering, and
repudiation on MI Band, One plus Band, Boat Storm smartwatch, and Fire Bolt
Invincible.
