IoT Security Assessment: Testing Connected Devices in Enterprise Environments — 日本企業向けガイド

Enterprise IoT deployments — smart building systems, environmental sensors, security cameras, badge readers, printers — often operate with minimal security controls on the corporate network. IoT security assessment covers: device firmware analysis, default credential testing, network exposure (what services do devices expose? are management interfaces accessible?), communication protocol security, update mechanism security, and the critical question of network segmentation (can a compromised IoT device be used as a pivot point to reach sensitive internal systems?). The last point is often the highest-impact finding — IoT devices on flat networks can provide attackers with a foothold inside the perimeter.
