Know what is connected
Start with a simple record of connected cameras, doorbells, speakers, lighting, heating, televisions and smart appliances. Include the account used to manage each system and who can access it. This makes it much easier to remove old devices or change access when circumstances change.
Use separate access where practical
Smart-home equipment should not automatically sit alongside the computers and phones that hold personal information. A separate network for connected devices can reduce the effect of a vulnerable appliance while keeping the home simple to use.
Guest Wi-Fi should be separate too. It gives visitors reliable internet without giving their devices access to the wider home network.
Review accounts and shared access
Use unique passwords and multi-factor authentication on the main accounts that control cameras, alarms and home automation. Review household, staff, contractor and former supplier access regularly. Individual access is safer and easier to remove than a shared password.
Keep the system maintained
Security updates apply to routers, cameras and smart devices as well as computers. Keep supported equipment current, replace devices that no longer receive updates and document who provides support for each important system.
A CONSIDERED NEXT STEP
Review the whole environment.
Technology risks rarely sit in isolation. A short review can identify priorities across people, devices, accounts, connectivity and recovery.
