Section 4

Topic 12: IoT and Smart Home Security

Assessing weak security designs in connected appliances, local cameras, smart lighting panels, and smart environment sensors.

Auditing device credentials, disabling vendor hardcoded entry accounts, and applying regular vendor edge patches.

Isolating insecure Internet-of-Things (IoT) nodes onto separate VLAN structures to block lateral movement vectors.

Hardening local video storage nodes, configuring strict out-of-network access rules, and managing hardware capture permissions.

Evaluating vendor lifecycle documentation policies, limiting device microphone exposure, and turning off unneeded cloud sync features.

Knowledge Check

What risk arises if an IoT device is placed on the same local network segment as a primary workstation?

If compromised via firmware bugs, the IoT node can serve as a pivot point for attackers to move laterally onto the workstation.
