Security factors are neglected while IoT devices are produced as they are only made for convenience. They are the most vulnerable machines prone to be attacked by hackers:  Weak default setting: Keeping the default setting of an IoT device can give unauthorized access to your network to an attacker.  Weak encryption: Strong encryption is often neglected in IoT devices making it easy to exploit.  Insecure firmware: The firmware of such devices is difficult to update for a layman, creating an easy entry point for a potential attack.
