In May 2020, NIST published Foundational Cybersecurity Activities for IoT Device Manufacturers (NIST IR 8259), which describes recommended cybersecurity activities that manufacturers should consider performing before their IoT devices are sold to customers. These foundational cybersecurity activities can help manufacturers lessen the cybersecurity-related efforts needed by customers, which in turn can reduce the prevalence and severity of IoT device compromises and the attacks performed using compromised devices. In the nearly 5 years since this document was released, it has been published in
