Nick decided that he wanted a more visual representation of the attempts bots made to attack and gain access to his server. To do this, he took a Raspberry Pi Zero W, a Pimoroni Blinkt<\/a> and a 7-segment display and created a device called the PiAlert, the case of which was 3D-printed. For the software, he configured fail2ban<\/a> (which monitors log files) to trigger a special action whenever it detected a potential intrusion. The triggered action is a Python3 script<\/a> (which Nick admits is an absolute mess!) which acts as an HTTP server, listening for the notifications from fail2ban and lighting up LEDs accordingly. The 7-segment display is also updated to show the number of intrusion attempts made.<\/p>\n

You can read more about the device on Nick’s blog<\/a>, including how to do it yourself..<\/p>\n

Here is a video of the PiAlert in action:<\/p>\n
