Strong encryption is one of the security techniques used to shield Internet of Things devices from cyberattacks. It guarantees the security of data transferred between devices and servers. Unauthorised access can be avoided with the use of authentication mechanisms like secure password management and multi-factor authentication (MFA). Updates to the firmware are necessary on a regular basis to address vulnerabilities and enhance device security. Intrusion detection systems (IDS) assist in monitoring and alerting for odd activity, while network segmentation reduces risk by separating IoT devices from important systems. Device authentication also makes sure that only reliable devices are able to connect to the network.

Consider enrolling in an IoT certification course from platforms like Coursera or edX if you want to expand your knowledge in this area.
