IoT devices ship with security debt. Default creds, no update mechanism, hardcoded keys. Supply chain compounds it.
IoT devices ship with security debt. Default creds, no update mechanism, hardcoded keys. Supply chain compounds it.
Issues
- Default credentials never changed (Mirai botnet exploited this)
- No firmware updates after sale (10-year-old vulns active)
- Hardcoded private keys discovered post-shipment
- Foreign-manufacture concerns (geopolitical)
- Recycled chips with unknown firmware
Indian regulatory environment
2022 CERT-In Direction requires equipment imported into critical sectors to be assessed. NCIIPC publishes vulnerability advisories. NCERT-CSF specific to telecom IoT (TRAI mandate).
Defender
- Network segmentation (IoT untrusted zone)
- Mandatory password change at deployment
- Update tracking; replacement schedule for unpatchable
- Vendor risk management for IoT manufacturers (RingSafe Trust use case)
