The following security capabilities can safeguard IoT devices against cyberattacks by making them more secure:
Secure boot : use of cryptographic code signing techniques.
Secure communication : it involves the use of security protocols like TLS, DTLS, and IPSec.
Secure firmware update : it ensures that the device firmware is updated only with firmware from the device OEM or other trusted party.
Data protection : encryption of all sensitive data stored on the IoT device.
Authentication : it verifies the credentials of users that request access to the device.
