Episode 16: Physical Security Features — Biometrics and NFC

Mobile devices increasingly rely on physical security features to prevent unauthorized access, and this episode explores those mechanisms in depth. We discuss biometric authentication options such as fingerprint readers and facial recognition systems, including where they are integrated into devices and how they are managed through software settings or group policy. You’ll also hear about token-based and proximity-based systems that utilize technologies like Near Field Communication to enforce access control.

This topic is important not only because it appears in multiple Core 1 objectives, but also because it overlaps with security discussions in Core 2. The episode explains how to distinguish between security hardware versus software and how CompTIA might frame exam questions using terms like multi-factor authentication or physical token presence. A strong understanding of these technologies gives you an edge when dealing with hybrid scenarios on the test. Brought to you by BareMetalCyber.com.
