Enterprises IoT Devices Security Concerns & Traffic Analysis

**Executive Summary:** Zscaler analyzed IoT device traffic from its cloud (26 Aug–26 Oct 2016), identifying common device types (cameras, TVs, printers, IP phones, DVRs), frequent use of insecure protocols (HTTP, basic auth), and weak/default credentials that expose devices to sniffing, MiTM, and automated compromise; although Mirai-style DDoS activity is discussed, Zscaler found no traffic spikes or evidence that their customers' devices were involved. The report highlights specific device vulnerabilities, provides security recommendations for enterprises and manufacturers, and offers guidance for detecting and remediating potentially compromised devices.
