AR-SEC: Augmented Reality Meets Security Assessment

Article summary

How I built a React Native mobile app that overlays real-time threat intelligence on physical spaces using AR — turning any smartphone into a security assessment tool.

The Idea Physical security assessments still rely on clipboards and photos. What if you could point your phone at a building entrance and see an AR overlay showing known vulnerabilities — exposed ports on nearby access points, CCTV blind spots, or badge reader models with CVEs?

Architecture AR-SEC is a React Native app with three modules: AR Scanner — uses the device camera with AR overlays to tag physical objects. Network Recon — passive Wi-Fi scanning and Bluetooth enumeration, displayed as AR nodes in physical space. Threat Intel Overlay — pulls CVE data and maps it to detected hardware models.

AR Integration The app uses ViroReact for 3D AR rendering on top of ARKit/ARCore. Detected access points appear as floating nodes in the camera feed — red for vulnerable, green for hardened. Tapping a node shows CVE details, remediation steps, and a risk score.
