Internet of Risks: Cybersecurity Risk in the Internet of Things | UpGuard

This article explains the Internet of Things (IoT), highlights key security risks (e.g., weak/no encryption, insecure interfaces, weak authentication, DDoS, device theft, firmware/software vulnerabilities, and ransomware), and recommends mitigations such as risk assessment, asset mapping, network segmentation, access control, and continuous monitoring with alerting. It also details common IoT protocols and ports—AMQP (5671), CoAP (5683/5684), MQTT (1883/8883), and OPC UA (4840)—advising closure or strict restriction when not required and use of encryption (e.g., DTLS/TLS) and VPN/firewall controls. The piece positions UpGuard’s external attack surface and vendor risk monitoring capabilities to detect exposed IoT services and support ongoing security oversight.
