IoT security procurement: ten blind spots to challenge

A procurement checklist covering credentials, updates, identity, encryption and end-of-life controls for IoT.

Every connected device is also a credential, software stack and operational dependency.

IoT security cannot be added solely at the firewall after deployment. Procurement decisions determine whether devices can be identified, updated, monitored and retired safely throughout a potentially long working life.

Ask about the device lifecycle

Confirm how default credentials are removed, firmware is signed and updated, vulnerabilities are disclosed and unsupported products are handled. If access to a device is difficult, remote maintenance and recovery become even more important.

Examine the connectivity layer

Understand how devices authenticate and where data travels.

  • Unique device and SIM identities
  • Private routing or APN options where appropriate
  • Encryption in transit and at rest
  • Usage restrictions and anomaly alerts
  • Remote suspension for lost or compromised endpoints

Make ownership explicit

Manufacturers, platform providers, connectivity partners and customers may each own part of the control set. Document responsibility for patches, certificates, monitoring, incidents and disposal so gaps do not sit between contracts.

What to do next

Add a security schedule to IoT procurement covering identity, software updates, data flows, monitoring, incident response and end of support. Reject answers that depend on undocumented future work.
