A botnet is a group of connected computers that work together on performing repetitive tasks, and it does not necessarily have a malicious purpose. Unfortunately, it’s possible for an attacker to take control of a botnet by infecting a vulnerable device with malware. Then they can use the network as a group of devices to perform DDoS attacks that can be much more dangerous, depending on the number of mechanisms involved. What’s more, since IoT devices often interact in the physical world in ways that other IT devices don’t, it’s difficult to monitor and safeguard them.
If we strive to protect IoT devices the same way we protect our conventional IT devices, there will invariably be faults in the system that cybercriminals might exploit. To eliminate vulnerabilities, we must think of IoT protection in its terms and take into account the various types of IoT use when we do.
