IoTLS 2.0: How Far Has IoT Industry Come in Securing Communications with TLS?

Transport Layer Security (TLS) is commonly used to secure communications over the Internet. However, since the rise of Internet of Things (IoT) devices, there have been concerns regarding the security practices adopted in the development of these devices. In particular, the study IoTLS (IMC'21) analyzed TLS practices in consumer IoT devices and revealed widespread use of insecure protocol versions, weak cipher suites, and improper certificate validation.
