With the proliferation of attack surfaces in IoT, the increase in firmware-based attacks on hardware, and growing threats to systems throughout their lifecycle, companies are beginning to embrace the new model of zero trust for systems. To help facilitate this zero-trust model, compute lifecycle assurance (CLA) is playing an increasingly pivotal role. CLA is a framework that helps analyze and address the security and integrity of a system and its components across its entire lifecycle. CLA recommends verifying that the system is still exactly what was ordered when received on site at the company after the Build and Transfer Stages.
