IoT security has evolved from an industry-focused problem into an essential investment. As organizational reliance on IoT devices is becoming ubiquitous, the potential consequences of compromise stemming from insecure IoT devices can be financially crippling for entities of all sizes. This scenario has resulted in corporations slowly recognizing that IoT cybersecurity is no longer a luxury, but an essential investment in long-term operational sustainability. But as with any technology, the requirements for effective IoT security are in a regular state of flux. As many IoT devices in use today lack an onboard agent with which to interact, there is growing demand for an agentless approach to IoT security. As a result, an effective IoT security solution will need to rely on machine learning, signature-less approaches for device classification.
