IoT Security for Business: Managing the Devices Nobody Thinks of as Computers

Printers, cameras, smart TVs, meeting-room systems, sensors and other connected devices are computers even when nobody thinks of them that way. They have software, network access, credentials and vulnerabilities, but they often sit outside normal device-management processes.

Know what is connected

Maintain an inventory of network-connected devices, who owns them, where they are, what they can reach and whether they still receive vendor updates.

Change default credentials

Default or shared administrator passwords are an unnecessary risk. Use unique credentials and limit who can reach management interfaces.

Keep firmware current

Connected devices need updates too. If a vendor no longer supports the model, decide whether it should be replaced, isolated or otherwise restricted.

Limit network access

A meeting-room display or printer usually does not need the same network access as a staff laptop or server. Network design can reduce what happens if a device is compromised.

Retire devices properly

Before disposal or resale, remove business configuration and stored data and remove the device from management/inventory records.

Printers create enough specific operational and search intent that we keep printer security as a separate related guide. For the broader security baseline, use the IT Security Self-Check.
