IIoT security practices

Consider the Distributed Denial of Service (DDoS) attack of October 16th, 2016, which almost brought down the internet on the east coast of the USA due to its attack on DYN's servers. This was later identified as having been due to a Mirai botnet attack using Internet of Things (IoT) devices, such as cameras, home routers, and so on. The Mirai bot targeted devices that used a stripped-down Linux OS by scanning the internet for open Telnet ports and logging into the device using one of the default passwords, thereby taking over the devices and using them for the DDoS. This is a very clever and effective way to implement a bot that rides on IoT devices. With billions of IoT devices around, these types of attacks have become common and it is natural that some of these attacks will be targeted toward IIoT devices as well, which could have a devastating...
