Many organizations have adopted agentless asset discovery to improve IoT security, and reports from the field are that it takes longer than expected to deploy and even longer to effectively remediate IoT device vulnerabilities. In part this is because asset discovery alone does not provide the context that IoT devices operate in, especially when it comes to the overall application workflow and how all elements need to work together in a tightly coupled fashion. This talk will show how application-directed discovery adds to the information uncovered in asset discovery, and how the two together dramatically accelerates the time to remediation and shrinking the attack surface. Data examples from application-directed discovery will be provided, as well as an industrial IoT use case.
