Frequently Asked Questions
- How often should I update my smart device passwords? Change passwords every 3-6 months and immediately after any suspected security breach.
- Do I really need a separate network for smart devices? Yes, a separate network for IoT devices adds an essential layer of security by isolating potentially vulnerable devices from your main network.
- What's the most important security feature for a smart home? Network segmentation and strong password policies are equally important as your first line of defense.
- Should I disable my smart devices when away? If not needed while away, disabling devices reduces potential attack vectors. However, some devices (like security cameras) need to remain active.
- How can I tell if my smart home has been hacked? Watch for unusual device behavior, unexpected network activity, changed settings, or unauthorized access attempts in your logs.
