Cameras and other smart devices: a simple security check

What is this about?

The camera watches the door. But who watches the camera's own door to the network? Smart devices need protection too. The same basic idea applies to connected equipment at work. [1, 2]

Before you start

You need permission to administer the device and access to its normal app or the manufacturer's instructions. For cooling, heating, locks or alarms, let the responsible technician plan changes. A security check should not accidentally switch off a freezer.

Do this

1. Write down the model, app and person responsible for the device. Then you know who can help when a warning appears.
2. Open the usual app or the manufacturer's own website. Check sign-in security: replace any remaining factory-set password and use a unique password. Enable an extra sign-in check if available. Store recovery access securely. [1, 2]
3. Look for updates and information about continued security support. Follow the manufacturer's instructions. Plan downtime before installation and do not disconnect power during the update. [2]
4. Do you need to reach the device while away? If not, disable unnecessary remote access using the model's instructions. First check that the feature is not needed for alarms or servicing. If unsure, ask for help. [2]
5. Ask IT or your network provider to check that the device's administration page is not unnecessarily exposed directly to the internet. A working app does not prove that the network is properly protected. [1]

Check the result

• Try a fresh sign-in and the device's normal function after the change. Also check any alarm function with the responsible person.
• Record the date, installed version, what you changed and who will do the next check. Never put passwords in this note.

Troubleshooting and things that need more help

Has the app stopped working? Stop making further changes and check the manufacturer's advice. Reverse only a documented change that the responsible person considers safe; do not open ports by guesswork. A factory reset may erase settings. Ask for help before resetting important equipment.

A separate network can limit which other devices the equipment can reach. Let IT plan this at work. At home, a guest network may be an option, but check that the model supports it and that controls and alarms work. [1, 3]

If security support has ended, ask the vendor to assess protection or replacement. The absence of an update button does not mean the device is secure. [2]
