Security Stack Integration
Overview
The security of connected devices is a growing concern and is now a top priority at every stage of the product design. Security has many aspects and breaches can occur along any single point of weakness. A comprehensive approach to device and system security is paramount and requires a thorough understanding of the relevant IoT security standards, security features required to mitigate risks, and implementation details

Secure Boot
Secure boot, the very first code that MCUs execute after the power-up or hard reset, even before the BIOS and OS run, verifies the software authenticity by showing the exact same image of the original firmware.
Secure FW OTA updates
The factory and OTA update images are encrypted using a device-specific key and stored in the secure file system. This prevents attackers from easily analyzing or running the image on another device, either for cloning purposes or to load an older image with known security vulnerabilities.
Secure Data Communication
Secure communication is when two entities are communicating and do not want a third party to listen in. ... Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what is said.
Device Authentication
Endpoint authentication is a security mechanism designed to ensure that only authorized devices can connect to a given network, site or service. The approach is also known as device authentication. ... The password response sent from the registered device verifies that the user is connecting from an authorized endpoint.
X.509 certificate support
An X. 509 certificate is a digital certificate based on the widely accepted International Telecommunications Union (ITU) X. 509 standard, which defines the format of public key infrastructure (PKI) certificates. They are used to manage identity and security in internet communications and computer networking.
Mutual Device Authentication
Mutual authentication or two-way authentication refers to two parties authenticating each other at the same time in an authentication protocol. It is a default mode of authentication in some protocols and optional in others.
