US Patent 11132447 Determining security vulnerabilities of Internet of Things devices

Determining security vulnerabilities of smart home devices. A method may include obtaining data regarding a first application associated with a first IoT device associated with a known security vulnerability; analyzing the data regarding the first application to analyze expected communications with the first IoT device; identifying a second application available for download associated with a second IoT device; analyzing expected communications between the second application and the second IoT device; comparing the expected communications between the first application and first IoT device and between the second application and second IoT device to determine a similarity level between the first and second IoT devices; determining the second IoT device shares the same known security vulnerability as the first IoT device based on determining the similarity level; and implementing a security action on the second IoT device based on determining that the second IoT device shares the same known security vulnerability.
