Dobësitë e Zakonshme të IoT-së

IoT devices share a recurring set of weaknesses that have been documented by OWASP IoT Top 10 for over a decade.

The list reads like a rogues gallery: weak or hardcoded passwords, insecure network services (telnet, open SSH with default credentials), lack of secure update mechanisms, use of unsupported components, insecure data transfer (HTTP instead of HTTPS, no cert validation), and insufficient privacy protections. The Mirai botnet exploited exactly these weaknesses in 2016, taking over hundreds of thousands of IP cameras and DVRs and launching some of the largest DDoS attacks ever recorded. Underneath, the root causes are economic: IoT vendors compete on price and time-to-market, security is rarely visible to buyers, and devices are often expected to run without updates for 5–10 years. Even when vulnerabilities are disclosed responsibly, patching depends on the customer updating the firmware — which most consumers never do. Countries like the UK (PSTI Act 2024) and the EU (Cyber Resilience Act) are now legislating minimum security requirements for connected products, which is starting to change vendor behavior. For individuals, the best defense is network segmentation: put IoT devices on a separate Wi-Fi SSID routed through a dedicated VLAN with restricted inter-VLAN traffic, so a compromised smart lightbulb cannot reach your workstation. For organizations, maintain an inventory of IoT devices, isolate them from production networks, and require a vendor security questionnaire before deploying new products.
