IoT devices are network-connected smart devices that can transmit, retrieve, and analyze data from other connected smart devices, such as smoke alarms, proximity sensors, or optical devices. The communication techniques used by the system will vary, however, they may include network protocols like BLE and ZigBee, as well as Wi-Fi, cellular data, and Ethernet.
Smart technologies are special in that they can make decisions without human intervention. This level of device autonomy poses difficulties in ensuring consumer-grade mobility and interoperability without jeopardizing IoT device safety.
Viruses, spyware, ransomware, and Trojans could use exploited service vulnerabilities in IoT devices to execute stealthy malware. These open-port services could be used by cybercriminals to gain access to sensitive data, listen in on private communications, or launch DoS and Man-in-the-Middle (MITM) attacks.
An administrator who knows which ports should remain open to connect vital services to the network is required for port maintenance. The port should be closed promptly if it is open and not connected to any critical network services.
It should not take much for a small network with few IP addresses to shut susceptible ports. However, with the ongoing addition of new devices to workplace networks, monitoring and managing open ports can be time-consuming.
System administrators must monitor their networks for unwanted open ports and services that share data and close them.
